What we've fixed in Reading this summer: a roofer's view of the local property mix

Thu, 30 Jul 2026 05:56:54 GMT

We've worked on roofs across Reading every week this summer. From Caversham to Earley, every neighbourhood has its own roof issues. Here's what we've been called out for.

Caversham — Victorian terraces and Edwardian semis

Caversham is one of the most rewarding areas to work in. The housing stock is genuinely varied, from tightly packed Victorian terraces near the river to broader Edwardian semis on the roads climbing toward Caversham Heights. Both eras produce a predictable set of problems, and this summer we've seen most of them.

Lead apron failures on bay windows are the most common call-out. The bay window is almost a defining feature of the Edwardian semi, and the lead apron that sits at the junction between the bay roof and the main wall is under constant stress. It expands in summer heat, contracts in winter cold, and after 100-plus years, even well-installed lead eventually lifts, cracks, or pulls away from the wall.

When it does, water tracks down the inside of the cavity and shows up as a damp patch on the ceiling above the bay, or a stain on the plasterwork inside the window reveal. We work to Lead Sheet Training Academy standards on all lead work, so when we refit or replace an apron, it's done correctly and fixed to last.

Chimney flashing leaks are the second recurring issue. Caversham's older properties often have original chimney stacks that have never had their flashings properly attended to. The step flashing and back gutter around a chimney are the most complex lead details on a domestic roof. When the mortar pointing fails, water gets behind the flashing and into the roof structure.

We've re-dressed and re-pointed several chimney stacks in Caversham this summer, including one on a detached Edwardian property near the Thames that had been leaking for two winters before the owner finally tracked down the source.

If you're in Caversham and you've got a bay window or a chimney stack, it's worth getting eyes on the lead before autumn arrives.

Tilehurst — 1930s housing, mixed concrete tile and clay

Tilehurst is dominated by 1930s semi-detached and detached houses, built during the interwar expansion of Reading's western suburbs. The roofs are typically pitched at a moderate angle and covered in either original clay plain tiles or, more commonly now, concrete interlocking tiles that were laid as replacements in the 1970s and 1980s. That replacement generation of concrete tiles is now 40 to 50 years old, and it's starting to show.

Ridge tile movement is the issue we see most in Tilehurst. On a concrete-tiled roof, the ridge tiles are bedded in mortar along the apex. Over decades, that mortar dries out, cracks, and allows the ridge tiles to shift. A loose ridge tile is more than a cosmetic problem. In a storm, it can lift completely and come down through the roof covering below, or land in the garden. More commonly, it simply allows water into the ridge line, which then saturates the felt and timbers underneath.

We've re-bedded and repointed ridge tiles on several Tilehurst properties this summer, and on two of them we found the underlying felt had already failed, requiring partial re-felting before the ridge work could be completed properly.

Fascia rot is the second consistent finding. The 1930s houses in Tilehurst were built with timber fascias and soffits, and many still have them. Decades of repainting can only do so much. Once water gets behind the paint film, the timber absorbs moisture and begins to decay. Rotten fascias don't just look poor, they undermine the gutter fixing and can allow birds and insects into the roof void.

We carry out Reading roof repair and roofline work together where needed, replacing timber fascias with low-maintenance uPVC boards that won't need painting again.

If your Tilehurst property still has its original timber roofline, it's likely due for attention.

Earley and Lower Earley — post-war and modern estates

Earley and Lower Earley are a different world from Caversham and Tilehurst. The housing here is mostly post-war, with large sections of Lower Earley built from the 1970s through the 1990s as part of one of the biggest housing developments in Europe at the time. The roofs are generally concrete interlocking tile on relatively shallow pitches, with felt and batten beneath. They were built quickly, and some of the detailing reflects that.

Storm damage to ridge tiles is the most frequent call-out after any significant weather event. The shallow pitches common on Lower Earley estates mean ridge tiles take more direct wind loading than on steeper Victorian roofs. We've been out to multiple properties in Earley this summer following the July storms, replacing ridge tiles that had lifted or cracked. In several cases the damage was to dry-fix ridge systems that had been installed as upgrades but not fixed correctly, allowing the plastic clips to fail under load.

Ageing felt roofs on garages are the second major issue we encounter across Earley. The integral and attached garages on these estates were almost universally covered in mineral felt when built, and that felt has a finite lifespan. Most felt flat roofs last 10 to 15 years. Many of the garages in Lower Earley are now 30 to 40 years old, and the felt is well past its useful life. We've replaced a number of garage roofs in the area this summer, in most cases upgrading to a modern torch-on system or GRP fibreglass finish that will outlast the original felt by decades.

Our free roof survey is particularly useful for Earley properties where the garage roof and the main roof may both need attention. We photograph everything and give you a clear picture of what needs doing now and what can wait.

Central Reading — Victorian terraces near the station

The streets around Reading station and the town centre contain some of the oldest and densest residential roofing in the area. Victorian terraces, many of them now in multiple occupation or recently converted back to single dwellings, with original Welsh slate roofs that have been patched, re-patched, and patched again over 130-odd years. This is where the most complex work tends to be.

Slipped slates are the most visible problem. Welsh slate doesn't wear out, but the nails that hold it do. As iron or steel fixings corrode, individual slates begin to slip. A handful of slipped slates is a repair job. A roof where the nails have generally failed is a re-slate. We've done both in central Reading this summer, and the honest assessment is always the same: if more than 20 to 25 per cent of the slates are loose or slipped, a full re-slate is more economical than repeated patching.

Valley failures are the second major issue on these terraced roofs. The valleys, where two roof slopes meet, are typically lined in lead or mortar-bedded tile, and on a terrace that runs for 20 or 30 houses, every roof has at least one valley. Failed valley lead or cracked mortar allows water to track down into the roof structure at exactly the point where two slopes are shedding water together. We've re-lined several valleys in central Reading this summer, working to British Standard 5534 throughout.

Complex chimney work is the third consistent finding. The Victorian terraces near the station often have multiple chimney stacks per property, some of them shared party-wall stacks serving several flues. The lead work on these is intricate, and it's not a job for anyone without proper heritage and lead skills. We've been carrying out this kind of work in Reading for 40 years, and we're NFRC-accredited, which means our work is independently assessed against national standards. That matters when you're dealing with a complex stack on a property that's been standing since 1880.

For anything in central Reading, get a proper survey done before committing to a repair. The full picture is rarely visible from the ground.

How Reading customers book us

We're based in Peppard Common, 7 miles from Reading. We're out in the town most weeks, and we can usually turn a survey around quickly. We offer a free photographic roof report for all Reading properties, which gives you a clear record of what's on your roof before any work begins. We've been working as roofers in Reading since 1985, and we know the housing stock well.

Booking a reroof for September: why now is the right time to start the conversation

Wed, 29 Jul 2026 09:54:12 GMT

If your roof needs replacing this year, the work happens in September, October, or November. The quote conversation happens now. That's not a sales pitch. It's just how reroof scheduling works, and understanding the timeline saves you money and stress.

Why most reroofs happen in autumn

September, October, and November are the busiest months of the year for roof replacement work, and there are good practical reasons for that.

Dry conditions without the heat. Summer gives you long days and dry weather, but high temperatures make working on pitched roofs genuinely uncomfortable and can affect some materials during installation. Autumn strips that problem out. You get stable, dry weather without July's heat.

The window before winter. A full reroof takes several days, sometimes longer depending on the size and complexity of the property. You need a run of dry weather to strip and relay properly. By November that run becomes harder to guarantee. September and October sit in the sweet spot.

Scaffold availability. Scaffolding contractors are in high demand through the summer. The good ones get booked out. Autumn sees some of that pressure ease, which matters both for availability and for cost, something we'll come back to shortly.

This pattern holds across the properties we work on regularly. Older Victorian and Edwardian terraces in Reading and Caversham, larger detached houses in Henley-on-Thames and the surrounding villages, barn conversions out towards Nettlebed and Stoke Row. Different buildings, same scheduling logic. Autumn is when the work gets done well.

The timeline from quote to start

Most homeowners underestimate how long the gap is between agreeing to a reroof and the roofers arriving on site. For a domestic property, the realistic timeline from first conversation to work starting is six to twelve weeks.

That's not because the work itself takes that long. It's because of everything that has to happen first. A proper quote takes time to put together. The surveyor needs to visit, assess the roof in full, and specify the scope of work. That specification then has to be priced accurately, scaffold needs to be measured and costed, and materials need to be ordered. Reputable roofers, particularly those working to British Standard 5534, don't price a reroof from the pavement and send you a figure by email the same afternoon.

Then there's booking. Good roofing firms don't have gaps sitting open in their schedule. If you want a September start, and you contact a contractor in late August, you will almost certainly be told the earliest available slot is October or November at best. The September slots will already be gone.

Forty years of scheduling reroofs across the Thames Valley tells us the same thing every year. The homeowners who get the dates they want are the ones who start the conversation in June or July. The ones who wait until August are already chasing the tail end of the season.

If you're reading this in July, you're in exactly the right position to secure a September start. But the window is short.

What a proper quote actually covers

A quote for a full roof replacement is not a single number on a piece of paper. A detailed, accurate quote is a document that specifies exactly what work will be done, with what materials, by whom, and under what terms. If a quote doesn't cover all of these points, it isn't a proper quote.

Survey and scope. The first step is a physical survey of the roof. A roofer who quotes without getting on the roof or using a drone to inspect it closely is guessing. The survey establishes the condition of the deck, the state of the timbers, the flashings, the valleys, and any areas of previous repair. All of that affects the scope and the price.

Materials specified. The quote should name exactly what is being used. Not "tiles" but the specific product, profile, and colour. Not "lead" but the code weight and the standard it's being worked to. You need to be able to compare one quote to another on a like-for-like basis.

Scaffold cost. Scaffold is often quoted separately, and it's one of the larger line items on a reroof. The quote should show the scaffold cost clearly, not fold it into a lump sum. You should know what you're paying for.

Waste removal. Stripping a roof produces a significant volume of waste. Old tiles, felt, battens, and sometimes sections of damaged decking all need to go. The quote should confirm how waste is handled and whether skip hire is included.

Payment terms. Reputable contractors set out clear stage payments tied to progress on site, not large upfront deposits before a single tile has been touched. The quote should state the payment schedule plainly.

Guarantee. Ask what guarantee comes with the work and what it covers. NFRC-accredited contractors work to a standard that supports meaningful guarantees. A guarantee that covers materials but not workmanship is not much use to you.

When Bondright carries out a roof survey before quoting, we go through all of these points. Nothing is assumed, and nothing is left vague for the homeowner to discover later.

Why booking in July saves you money

Scaffold pricing is not fixed year-round. It moves with demand, and demand peaks in late summer.

Scaffolding contractors serving the Reading and Henley areas run at high capacity from June through August. Builders, window companies, painters, and roofers all compete for the same scaffold crews and the same equipment. When demand is high, prices go up. That's not unusual, it's just how the market works.

The premium for booking scaffold in August versus July can be meaningful. Based on typical domestic reroof jobs in this area, the difference in scaffold cost alone between a mid-summer booking and a peak-August booking can run to several hundred pounds. On a full reroof, that's real money.

Booking your reroof in July, with a September start date, means your scaffold is contracted before the August peak. Your roofer can lock in the scaffold at the earlier rate. That saving flows directly to you.

There's a secondary benefit too. A July booking gives your contractor time to order materials without rushing. Supply chains for roofing materials aren't always instant. Ordering with a six-to-eight-week lead time means your roofer isn't chasing a delivery the week before work starts, which is when mistakes and delays happen.

Hamptons International, who use us as an approved contractor, understand this kind of scheduling detail. So do the property managers and estate agents across the Thames Valley who plan maintenance work properly. The principle is the same whether you're managing a portfolio or replacing the roof on your own home. Plan early, book early, save money.

Start with a free photographic survey

The first step isn't signing anything or committing to a date. It's understanding exactly what your roof needs.

Bondright offers a free roof report, a photographic survey that gives you a clear picture of the roof's condition before any conversation about price. You'll see what we see, in images, with notes on what needs doing and why. That report is yours to keep and to use when comparing quotes.

From there, if a full replacement is the right course of action, we can put together a detailed quote for your roof replacement services that covers everything described above, scope, scaffold, waste removal, payment terms, and guarantee.

July is the right time to start that conversation. Get in touch to book your survey and get on the autumn schedule before the slots go.

Flat roof repairs in summer: what we check and why heat damage is often invisible from below

Tue, 28 Jul 2026 04:55:48 GMT

Most flat roof failures start at the top and only reach the ceiling months later. By the time you see a damp patch, the surface has usually been compromised for a season.

That delay is what makes summer the most deceptive time of year for flat roofs. The sun is doing damage you cannot see from inside, and by the time autumn rain arrives to reveal it, the window for a straightforward repair may have already narrowed. This post explains what actually happens to a flat roof in summer, what we look for when we inspect one, and how we decide whether a patch or a full replacement is the right answer.

Why flat roofs fail in summer specifically

Heat is harder on a flat roof than most people realise.

UV degradation works slowly and continuously. Prolonged sun exposure breaks down the surface layer of a flat roof over time, making it brittle, prone to cracking, and less able to shed water effectively. This process happens across the whole surface, not just at obvious weak points. A roof that looks intact from the outside, and shows nothing unusual from the inside, may already have a surface that will fail as soon as the next significant rainfall puts it under pressure.

Thermal expansion is a separate problem. A flat roof surface heats up significantly during a hot day and cools again at night. That cycle of expansion and contraction puts repeated stress on seams, joints, and the points where the roof meets a wall or upstand. Over a number of summers, those stress points can open up, even on a roof that was installed correctly. The movement is small each time, but it accumulates.

Ponding water causes damage in summer too, though in a different way than in winter. When water sits on a flat roof in warm weather, it heats up and evaporates, but it leaves behind whatever it carried: dirt, debris, and mineral residue. Over time that residue builds up in low spots and adds weight, holds moisture against the surface, and accelerates the breakdown of the material beneath it. A flat roof with persistent ponding is ageing faster than one that drains cleanly.

Together, these three processes mean a flat roof can be in serious decline by late summer while showing nothing from below. The damage is real and ongoing. It just has not reached the ceiling yet.

What we check on a flat roof survey

A flat roof survey is not a quick glance from ground level. We get up on the roof and work through it methodically.

Surface condition is the starting point. We look at the whole surface for signs of cracking, blistering, splitting, or any areas where the surface has lost integrity. Some of this is obvious. Some requires closer inspection, particularly in areas that have been in direct sun all day or where water has been pooling.

Seam integrity matters because seams are where failures concentrate. Wherever the roof surface has a join, that join is a potential weak point. We check each one for signs of lifting, separation, or stress cracking, particularly around edges where thermal movement is greatest.

Edge trims and upstands are checked carefully. The point where a flat roof meets a wall, a parapet, or a raised edge is where water most commonly finds a way through. These junctions need to be properly formed and properly adhered. If an upstand has pulled away from the wall, or an edge trim has lifted, water will get behind it.

Outlets and drainage are inspected for blockage and for the condition of the area immediately around them. Outlets that are partially blocked slow drainage and increase ponding. The surface around an outlet often shows the first signs of stress because water sits there longest.

Parapet flashings, where present, are checked for condition and fit. A flashing that has cracked, lifted, or lost its seal at the top allows water to track down behind the roof surface, which is a failure mode that can cause significant damage before it becomes visible internally.

The substrate below is assessed where we can access it. If the roof surface has been allowing moisture in, the deck beneath it may have started to soften or deteriorate. That changes the repair options significantly. A sound substrate means a patch or a new surface is straightforward. A damaged substrate means the work is more involved.

We provide all of this as a written, photographic report. You get a clear picture of what is actually happening on your roof, not a verbal summary on a doorstep.

When patching is the right call

A patch repair is the right answer when the failure is localised and the rest of the roof is in reasonable condition.

A single seam that has lifted around a corner, or a small area of surface damage near an outlet, does not mean the whole roof needs replacing. If the substrate is sound, if the rest of the surface is still performing, and if the failure has a clear and contained cause, a well-executed repair will extend the life of the roof without the cost and disruption of a full replacement.

We are straightforward about this. If a patch will do the job, we say so. There is no benefit to us in recommending a full replacement when a repair is the honest answer. We have been doing roof repairs across the Thames Valley for 40 years, and a reputation built over that time is worth more than an upsell on a single job.

The key condition is that the rest of the surface is genuinely sound. A patch on a roof that is failing across its whole area is short-term thinking. It will hold in one place while the surface continues to deteriorate around it. That is why the survey matters. It tells you whether you are dealing with a single localised problem or something more widespread.

For many kitchen extension roofs in Henley and garage roofs across the area, a targeted repair at the right time is all that is needed to get several more years of reliable performance.

When the whole roof needs replacing

There are situations where a patch is not the honest answer, and we will tell you clearly when that is the case.

Widespread surface failure is the clearest signal. If the surface is cracking, blistering, or showing UV degradation across most of its area, patching individual spots will not address the underlying condition. The surface has reached the end of its serviceable life and needs to come off.

Ponding across the whole roof that has been present for years indicates that the falls, the slight slopes built into a flat roof to direct water to the outlets, are no longer doing their job. That may be because the substrate has deflected, or because the roof was never laid with adequate falls. Either way, it is a structural problem that a surface repair cannot fix.

Substrate damage is the other deciding factor. If moisture has been getting through for long enough to soften or rot the deck below, the repair has to go deeper than the surface. In that situation, a full replacement is the only approach that will produce a durable result.

This pattern is common in 1960s and 1970s extensions across Reading and the surrounding area. Roofs of that age have often had one or two surface repairs over the decades, and there comes a point where the substrate has simply had enough. A full replacement at that stage, done properly, should give you another 20 to 25 years without the cycle of repeated repairs.

Our flat roof services cover both repair and full replacement, and the survey is what determines which one is appropriate for your roof.

If your flat roof is ageing, if you have noticed a damp patch inside, or if you simply have not had it looked at in a few years, a survey is the right starting point. We will get up on the roof, go through it properly, and give you a written photographic report of what we find. No obligation, no pressure, just a clear picture of what is actually there.

Roof valley leaks: why we see them most on Henley and Reading older properties

Fri, 24 Jul 2026 06:00:03 GMT

A roof valley is the concentration point for water flow on a pitched roof. When it fails, the leak is fast and the damage spreads quickly. The fix is specialist work.

Valley failures are one of the most common calls we take from homeowners across Henley, Reading, and the surrounding villages. They are also one of the most misdiagnosed. If you have a stain on a bedroom ceiling and no obvious missing tiles, the valley is often where the problem started.

What a roof valley is and why it matters

A valley is the internal angle formed where two roof slopes meet. Think of the crease between two pages of an open book, but running down your roof at a pitch. Every drop of rain that falls on either slope drains toward that line.

That concentration effect is significant. On a typical pitched roof with one or two valleys, those channels can carry somewhere between 30 and 40 percent of all the water falling on the roof. On a more complex roofline, with multiple gables or dormers, the proportion can be higher still.

The older properties in Henley-on-Thames tend to have exactly that kind of complexity. Steeply pitched Victorian and Edwardian houses with multiple gables, as you find across Reading and Caversham, often have three or four valleys working at once. Each one is under constant hydraulic pressure every time it rains.

The valley lining itself sits beneath the tiles or slates on either side. It is usually formed in lead, mortar, or a moulded GRP (fibreglass) profile. In older properties, it may be the original lead laid decades ago, or a mortar repair done at some point in between. Either way, it has been handling that water volume for a long time.

When the lining degrades, even slightly, water finds its way underneath. And once it is underneath, it travels.

The four ways a valley fails

Not all valley failures look the same. We see four distinct failure modes, and each one has a different repair path.

Split or cracked lead. Lead is the traditional and most durable valley lining. But lead moves. It expands in heat and contracts in cold, and over many years that thermal cycling causes fatigue. Splits develop along the centre of the valley, or at the edges where the lead was dressed against the tiles. On older Henley properties with original lead valleys, this is the failure mode we see most often. The splits can be hairline and still let in a significant volume of water.

Cracked or degraded GRP. From the 1980s onward, many valleys were lined with moulded fibreglass sections. GRP is light, fast to install, and initially effective. Over time, UV exposure and thermal movement cause it to become brittle. It cracks along the spine of the valley or at the joints between sections. We see a lot of failed GRP valleys on Caversham 1930s detached homes where a previous owner had the roof worked on and opted for a cheaper lining. It performs well for a decade or so and then deteriorates quickly.

Eroded mortar joints. Some valleys, particularly on older clay-tile roofs, were finished with mortar pointing along the tile edges rather than a continuous lining. The mortar seals the gap between the tile and the valley board. When that mortar erodes, which it does over years of freeze-thaw cycles and rain, the gap opens up and water runs straight through. This is a gradual failure. It often goes unnoticed until the pointing has broken down across a long section.

Badly cut or incorrectly bedded tiles. This one is not always age-related. It is often the result of previous repair work done without proper knowledge of how a valley should be cut and dressed. Tiles on either side of a valley need to be cut at the correct angle and positioned to direct water into the valley, not past it. When they are cut too short, or laid at the wrong pitch, water runs behind them. We find this regularly when we survey roofs that have had work done by someone without specialist valley experience.

Why the leak appears nowhere near the valley

This is the detail that confuses most homeowners. The valley is on the back of the house. The ceiling stain is in the front bedroom. Surely they cannot be connected?

They almost always can be.

Water entering through a failed valley does not fall straight down. It hits the roof timbers, the sarking felt, or the top of a ceiling joist, and then it travels. It follows the slope of the timber, runs along a rafter, pools at a joist, and eventually soaks through the plasterboard at whatever low point it reaches. That low point might be two or three metres from where the water entered.

On a complex Victorian roofline with multiple internal angles, the travel distance can be even greater. Water entering at a valley above a rear extension can appear on the ceiling of a front room. Water entering at a high valley on a gabled dormer can stain a ceiling two floors below if the felt has degraded and the water is finding its way down a wall cavity.

This is why a visual inspection from inside the loft is always part of any proper valley assessment. The stain tells you there is a problem. The loft tells you where the problem actually is. Without both, you are guessing.

We have carried out heritage roof work on some of the older properties in this area, where the roof structures are complex and the water pathways are anything but obvious. Forty years of working on these roofs teaches you to follow the water, not the stain.

What proper valley repair involves

The repair approach depends on what is there and how far the failure has progressed.

Partial repair is appropriate when the lining is in reasonable overall condition and the failure is localised. A split section of lead can be patched or replaced in that section. A short run of failed mortar can be raked out and repointed with the correct material. This is the lower end of the cost range, typically from around £600 for a straightforward repair to a single valley section.

Full valley replacement is needed when the lining has failed along its length, when the underlying timber has been damaged by sustained water ingress, or when the existing material is simply at the end of its useful life. A full replacement means lifting the tiles on both sides of the valley, removing the old lining, inspecting and treating the valley board and any affected timbers, and laying a new lining to current standards.

We work to British Standard 5534 on all pitched roof work, and our lead work is carried out to Lead Sheet Training Academy standards. On older properties, particularly listed buildings or those with original lead, getting the specification right matters as much as the physical repair.

Full valley replacement typically runs from around £800 to £2,000 depending on the length of the valley, the access required, and whether any timber work is needed. On a complex roofline with multiple valleys, the cost reflects the time and the number of valleys involved. We always specify exactly what is needed before any work starts. You will not be quoted for a full replacement if a partial repair is the right answer.

The NFRC sets the professional standards we work to, and those standards include honest scoping of work. Replacing more than is necessary is not good practice, and it is not how we operate.

What the May heatwave did to your roof (and what to check this week)

Wed, 20 May 2026 19:23:00 GMT

Last week's heatwave was the hottest May on record in this part of the country. Roofs felt it. Here's what to look for now, before autumn arrives.

What heat does to roof materials

Most homeowners think of roof damage as a winter problem. Frost, ice, heavy rain. But a sustained heatwave, particularly one as sharp as May 2026, puts real stress on every material up there.

Lead expands in heat and contracts as it cools. Over a long hot spell, that movement is significant. Lead flashings around chimneys, valleys, and dormers can pull away from the mortar that holds them, or develop hairline cracks at folds and joints. On older properties across Henley and the surrounding villages, a lot of that lead has been in place for decades. It's had many summers. But record temperatures push it further than usual.

GRP flat roofs (fibreglass) are vulnerable to UV degradation over time. A prolonged heatwave accelerates that process. The surface can begin to chalk or blister, and any existing micro-cracks will have widened as the material expanded.

Felt roofs , particularly on 1960s and 70s extensions, soften in high heat. As the temperature drops overnight, that felt can shrink slightly. Repeated over several days, this pulls seams apart and creates splits at edges and upstands.

Mortar bedding on ridge tiles and verges dries out fast in sustained heat. Older mortar, already porous, loses its remaining moisture content and becomes friable. What looked solid in April may have crumbled by June.

Timber in the roof structure moves too. Rafters and battens absorb heat and expand, then contract overnight. On period properties with original timbers, this movement can shift tiles that were already sitting loosely.

None of this means your roof has failed. But the stress has been applied. The question is whether it has shown.

The five visible signs of heat damage to look for now

You don't need to go on the roof to do a first check. Start from the ground with a pair of binoculars, and look carefully at each of the following.

Cracked or lifted lead flashings. Look at the joints where your roof meets a chimney stack, a parapet wall, or a dormer. Lead flashings should sit flat and tight. If you can see a gap, a lifted edge, or a crack running along a fold, that needs attention. Water will find it in the first autumn downpour.

Lifted or displaced tiles. A tile that has shifted even a centimetre can let water in. Look along the ridge line and down the slopes. Any tile sitting higher than its neighbours, or at an angle, has moved. On Victorian terraces in Reading and Caversham, where roofs are steep and tiles are bedded on lime mortar, movement after a heatwave is not unusual.

Splits in felt or GRP. If you have a flat roof on a rear extension, walk out and look at it from an upstairs window if you can. You're looking for bubbles, splits, or areas where the surface has gone white and chalky. On a 1960s or 70s extension with original felt, a hot May is exactly the kind of event that tips ageing material into failure.

Mortar gaps at ridges and verges. The ridge is the line of tiles running along the top of your roof. The verges are the edges at each gable end. Both are bedded in mortar. Look for gaps, missing chunks, or sections where the mortar has crumbled away. A gap at a ridge tile is a direct route for water into the roof void.

Displaced lead aprons. These sit at the base of chimney stacks and around soil pipes. They're often the first to move in a heatwave because they're exposed to full sun. If an apron has lifted or buckled, the seal is broken.

Why heat damage often shows up weeks later

This is the part most people don't expect. You get through the heatwave, the weather breaks, and you think the worst is over. Then a leak appears in August, or you notice a damp patch in September, and you wonder where it came from.

The answer is thermal cycling.

When temperatures swing, materials expand and contract repeatedly. After a heatwave like May 2026, the roof doesn't just go back to where it was. Materials that have been pushed to their limits don't always return to their original positions. A lead flashing that lifted slightly will have let in a small amount of moisture each time it moved. Mortar that cracked under heat will continue to crumble as cooler, wetter weather arrives.

The effect is cumulative. A roof that looked fine during the heatwave may develop a visible problem four or six weeks later, when the thermal cycling has completed its work and rain starts probing the gaps.

This is why a post-heatwave check matters now, in late June, rather than waiting until something goes wrong in October. By then, the damage has had months to develop. Water may have reached timbers, insulation, or ceilings. What would have been a straightforward repair in summer becomes a bigger job in autumn.

We've been working across the Thames Valley since 1985. In forty years, we've seen this pattern after every significant heatwave. The homeowners who act early spend less.

When to call us, and when to monitor

Not everything you spot needs immediate attention.

If you can see a clear gap in a flashing, a displaced tile, or crumbled mortar at a ridge, that's worth getting looked at now. These are open routes for water. A wet summer or an early autumn storm will find them.

If you can see a small area of chalking on a GRP roof, or a tile that looks slightly high but is otherwise intact, it's reasonable to have it inspected and assessed rather than assuming the worst.

The key is knowing what you're looking at. A photographic roof inspection gives you a clear record of what's there, what's changed, and what needs doing. As NFRC-accredited contractors, we work to British Standard 5534 on all tiled and slated roof work. That means our assessments are grounded in what the standard actually requires, not guesswork.

If you're in Nettlebed, Sonning Common, Wargrave, or anywhere else in the villages around Henley and Reading, the same heat hit your roof. The property type matters more than the postcode. Period properties with mortar bedding, Victorian terraces with original lead, and 1960s extensions with felt are the ones to prioritise.

If you're unsure, call us. We'd rather tell you everything is fine than have you find out it isn't when the ceiling comes down.

Book your free post-heatwave roof report

The simplest thing you can do this week is book a free photographic roof report . We carry out the inspection, photograph every area of concern, and have the report back to you within 48 to 72 hours. There's no charge and no obligation.

If something needs roof repair , we'll tell you exactly what, why, and what it will cost. If everything is fine, you'll have a photographic record of your roof's condition taken in the summer of 2026.

For roofers in Henley and across the Reading area, contact us through the website to book your inspection now, while the heatwave is fresh and any damage is easiest to catch.

Flat Roof Reroofing in Henley: A Complete Transformation

Wed, 22 Apr 2026 08:24:02 GMT

Expert flat roof reroofing in Henley using durable, weatherproof systems built to last

If you own a property with a flat roof in Henley, you’ll know how important it is to keep it in top condition. Over time, even well-built flat roofs begin to show signs of wear—ponding water, cracking felt, or failing seams. That’s where flat roof reroofing becomes not just an option, but a smart investment.

In this recent project, we carried out a full flat roof transformation, replacing an ageing surface with a modern, durable system that not only protects the building but enhances its functionality and appearance.

Why Flat Roof Reroofing Matters

Flat roofs are exposed to the elements year-round, and unlike pitched roofs, water doesn’t run off as easily. This makes them more vulnerable to:

Water pooling and leaks
UV degradation
Thermal expansion and cracking
General ageing of materials

Flat roof reroofing addresses all of these issues by replacing the worn-out layers with a new, high-performance system designed for longevity.

Rather than constantly patching repairs, reroofing gives you a fresh start—improving reliability, insulation, and overall property value.

A Recent Flat Roof in Henley - What Was Done

This project involved a large flat roof in Henley that had reached the end of its lifespan. The goal was to modernise the structure while ensuring long-term durability.

Key upgrades included:

Installation of a new torch-on felt roofing system
Addition of multiple skylights to increase natural light
Improved waterproofing and drainage performance
Clean, uniform finish for a professional appearance

The result is a robust, weather-resistant surface that will perform reliably for years to come.

Benefits of Modern Flat Roof Systems

When you invest in flat roof reroofing , you’re not just fixing problems—you’re upgrading your entire roof system.

1. Long-Term Protection

Modern materials such as torch-on felt are designed to withstand harsh weather conditions, reducing the risk of leaks.

2. Improved Energy Efficiency

New roofing layers can significantly improve insulation, helping reduce heating costs.

3. Enhanced Natural Light

Adding skylights transforms internal spaces, making them brighter and more usable.

4. Increased Property Value

A newly installed flat roof in Henley is a strong selling point for both residential and commercial properties.

When Should You Consider Flat Roof Reroofing?

If you notice any of the following, it’s time to act:

Persistent leaks or damp patches
Visible cracks or blistering on the surface
Roof age exceeding 15–20 years
Frequent repair costs adding up

Delaying reroofing often leads to more expensive structural damage, so early action is key.

Choosing the Right Contractor in Henley

Not all roofing work is equal. For a successful flat roof reroofing project, you need:

Proven experience with flat roofing systems
High-quality materials
Proper installation techniques
Guarantees and insurance

A professional team ensures the job is done right the first time, saving you time and money in the long run.

Final Thoughts

A well-executed flat roof reroofing project can completely transform your property—both visually and structurally. If you have a flat roof in Henley that’s showing signs of age, now is the perfect time to consider an upgrade.

With modern materials, expert installation, and thoughtful additions like skylights, your flat roof can become a long-lasting asset rather than a recurring problem.

From Homes to Large Industrial Buildings – Bondright Roofing Services Can Do It All

Fri, 06 Mar 2026 08:37:40 GMT

This is a subtitle for your new post

Roofing comes in many forms. From small residential repairs to large commercial and industrial installations, every building has its own challenges and requirements. At Bondright Roofing Services , we take pride in being able to handle projects of all sizes with the same level of care, professionalism, and attention to detail.

Whether it’s a private home, a school building, a warehouse, or a commercial complex, our team brings the experience and practical knowledge needed to deliver reliable and long-lasting roofing solutions.

Working on Large Roofing Structures

Large buildings such as schools, industrial units, and commercial premises require a different level of planning and execution compared to standard residential roofing. The roof areas are often extensive, and they may include complex elements such as rooflights, ventilation systems, drainage solutions, and structural considerations.

In the project shown above, our team worked on a large roof structure featuring continuous rooflights designed to allow natural light into the building. Installations like this require careful attention to waterproofing, structural alignment, and long-term durability.

Every stage of the work is carried out with precision to ensure the roofing system performs effectively against the UK’s often unpredictable weather conditions.

The Importance of Proper Roofing Systems

A roof is more than just a covering for a building. It protects the structure from water damage, regulates temperature, and contributes to the overall longevity of the property.

For larger buildings, proper roofing systems become even more critical because any issues can affect large interior areas and potentially disrupt business operations or daily activities.

At Bondright Roofing Services , we focus on solutions that provide:

Strong weather resistance
Long service life
Reliable waterproofing
Efficient drainage
Safe and durable installations

Using quality materials and proven techniques ensures that the finished roof stands up to the demands placed upon it.

Residential, Commercial, and Industrial Expertise

One of the strengths of our team is the ability to work across different sectors. Roofing requirements vary greatly depending on the type of property, and having experience in multiple areas allows us to provide the right approach for each project.

Our services include:

Residential roof repairs and replacements
Commercial roofing projects
Industrial roofing systems
Roof maintenance and inspections
Leak detection and repair
Rooflight installations and repairs

By combining practical experience with reliable workmanship, we ensure that every project is completed to a high standard.

A Commitment to Quality Workmanship

Every roofing project, whether large or small, deserves the same professional approach. At Bondright Roofing Services, we believe in straightforward service, honest advice, and quality results.

From the initial inspection to the completion of the work, our goal is to provide roofing solutions that property owners can rely on for years to come.

Emergency Flat Roof Leak Repair in Tunbridge Wells – Main Street Shop Saved from Flooding

Fri, 06 Feb 2026 13:17:29 GMT

Rapid Response, Professional Assessment

Last weekend we were called out to an urgent emergency leak repair in Tunbridge Wells , after a newly opened main-street shop discovered active water ingress coming through their flat roof.

With the business having just launched , the timing couldn’t have been worse. Persistent rainfall combined with a worn-out flat roof system meant water was beginning to penetrate the structure, threatening ceilings, electrics, stock, and potentially forcing the shop to close its doors only days after opening. Left untreated, the situation could have quickly turned disastrous , with flooding damage and costly downtime.

Despite it being a Saturday , and the site being a considerable distance from our usual working area, we attended as soon as possible to prevent further escalation.

Rapid Response, Professional Assessment

On arrival, our team carried out an immediate inspection of the flat roof area. The issue was clear:

The existing roof covering had deteriorated over time
Previous detailing around edges, upstands, and service penetrations had failed
Water was finding its way through vulnerable points during heavy rain

This wasn’t something a temporary patch would solve. The roof required a proper professional intervention , and it required it fast.

High-Performance Rubber Roofing System Applied

To stabilise the situation and protect the business long-term, we treated the affected roof areas using our high-performance liquid rubber waterproofing system.

This system is specifically designed for:

Emergency leak containment
Long-term flat roof protection
Seamless coverage with no joints or weak points
Excellent resistance to standing water and extreme weather

The membrane was carefully applied to critical areas including:

The main flat roof surface
Perimeter edges and upstands
Around existing air-conditioning units and pipe penetrations

Once cured, the result is a fully sealed, seamless, and durable waterproof layer , designed to perform reliably even during prolonged periods of heavy rainfall.

Business Protected, Leaks Under Control

The leaks were brought fully under control, and the shop was able to continue trading without disruption. Most importantly, the roof is now protected against the next spell of bad weather, ensuring that future rainfall will not affect the business or its operations.

Our rubber roofing system comes with a long guarantee , giving the client peace of mind that this wasn’t just a quick fix - it was a lasting solution.

Emergency Roofing You Can Rely On

This job is a perfect example of why rapid response and correct materials matter. Flat roof leaks can escalate quickly, especially for commercial properties, but with the right approach they can be resolved efficiently and effectively.

If you’re experiencing:

Sudden flat roof leaks
Water ingress during heavy rain
Concerns over an ageing or worn roof covering

We’re always ready to help - even at short notice .

�� Bondright Roofing is here and can ensure emergency and planned flat roof repairs available across Tunbridge Wells and surrounding areas.

Supporting the NHS: Emergency Leak Repair at King Edward VII Hospital

At Bondright Roofing Services , we take pride not only in the quality of our workmanship, but also in responding quickly when it matters most - especially in sensitive environments such as healthcare facilities.

Recently, our team was called to assist the NHS at King Edward VII Hospital , where a leaking area had developed above one of the hospital’s consulting rooms.

The Situation

The leak was beginning to affect the internal space used for patient consultations - an area where reliability, cleanliness, and safety are critical. In healthcare environments, even a small roof issue can quickly escalate into disruption for staff and patients if not dealt with promptly.

Our Response

Upon arrival, our team carried out a rapid inspection to identify the source of the leak. The issue was traced to a vulnerable section of the roof where water ingress had occurred due to weather exposure and ageing materials.

We acted immediately to:

Secure the affected area
Stop active water ingress
Carry out targeted repairs suitable for the existing roof structure
Ensure the consulting room could continue to be used safely

All works were completed with minimal disruption, following site safety procedures appropriate for a live hospital environment.

Working in Healthcare Environments

Hospitals require a higher level of care and awareness during maintenance works. Our team is experienced in operating in sensitive locations, understanding the importance of:

Quiet, efficient working practices
Clean and controlled repair methods
Clear communication with on-site staff

We’re proud to have supported the NHS in maintaining a safe and functional environment for both patients and healthcare professionals.

A Commitment Beyond Roofing

Every job matters - but some carry extra responsibility. Supporting essential public services is something we take seriously, and we’re pleased to have been able to respond quickly and professionally when help was needed.

If you manage a commercial, healthcare, or public-sector property and require reliable roofing support or emergency repairs, our team is always ready to help.

Emergency Roofing Intervention at NHS Dellwood Community Hospital, Reading

Mon, 26 Jan 2026 14:48:52 GMT

Safeguarding Patients and Staff During an Urgent Roof Leak

Our team was recently called out to an urgent roofing emergency at NHS Dellwood Community Hospital , where a sudden roof leak was beginning to affect patient wards within the hospital.

In healthcare environments, even a small roofing issue can quickly escalate. Water ingress poses serious risks - from damage to ceilings and electrical systems to disruption of critical patient care areas. Understanding the sensitivity and urgency of the situation, our team responded immediately.

Rapid Response in a Live Hospital Environment

Upon arrival, we carried out a swift but thorough assessment to identify the source of the leak. Working carefully around an active hospital setting, we implemented immediate temporary measures to stop further water ingress and protect the affected wards.

Once the situation was stabilised, we proceeded with the necessary emergency repairs , ensuring the roof was made fully watertight and safe. All work was completed with strict attention to health and safety protocols, minimising disruption to hospital staff, patients, and daily operations.

A Trusted Partner in Critical Situations

Hospital sites demand a high level of professionalism, discretion, and technical expertise. Our experience working on sensitive and high-risk environments allows us to act decisively while maintaining the highest standards of workmanship and safety.

The hospital team expressed their appreciation for the speed, efficiency, and care shown throughout the intervention - and most importantly, the issue was resolved before any further impact on patient care.

Always Ready When It Matters Most

This call-out is another example of our commitment to being there when it truly matters. Whether it’s a healthcare facility, hotel, or public building, we understand that roofing emergencies can’t wait .

If you’re responsible for a site where safety and continuity are critical, you can rely on our team to respond quickly, work safely, and deliver effective solutions - even under pressure.

Emergency Roof Safety Work at Prestigious Relais Hotel, Henley-on-Thames

Thu, 15 Jan 2026 09:41:32 GMT

Ensuring public safety through fast, professional roofing intervention

Our team at Bondright Roofing Services were recently called out to the prestigious Relais hotel in Henley, following a health and safety concern involving a roof-mounted snow guard.

Due to the nature of the building and the volume of guests and members of the public using the premises daily, the issue required urgent attention . A compromised or incorrectly secured snow guard can pose a serious risk, particularly in winter conditions, where falling snow, debris or even tiles could endanger people below.

Upon arrival, our experienced roofing team, led by our own Dave, with over 35 years’ experience, carried out a full safety assessment of the affected area. We identified the issue, mounted a brand-new snow guard installation correctly on the whole width of the required area, and ensured the roof system was made fully safe and compliant . All work was completed with minimal disruption to the hotel’s operations, while maintaining the highest safety standards at all times.

Given the reputation of the property and its public-facing nature, it was essential that the work was carried out promptly, professionally, and discreetly . We are pleased to say that the issue was resolved efficiently, and the client expressed their appreciation for the fast response and quality of workmanship.

This project highlights the importance of regular roof inspections and professional installation of safety features such as snow guards - particularly on commercial and hospitality buildings where public safety is paramount.

If you require emergency roofing work , safety inspections, or specialist roof installations, our team is always ready to help.

Is Your Roof Still Safe After a Storm? What to Check Immediately

Wed, 17 Dec 2025 16:31:22 GMT

Storms are a fact of life in the UK - strong winds, heavy rain, and sudden temperature changes can all take a toll on your roof. While some damage is obvious, much of it isn’t. In fact, many serious roofing issues start small and go unnoticed until they turn into costly repairs.

If your area has recently experienced a storm, here’s what you should check straight away to make sure your roof is still protecting your home properly.

1. Look for Missing or Dislodged Tiles

High winds are one of the biggest causes of roof damage. Even if tiles haven’t completely fallen off, they can shift, crack, or lift slightly.

What to look for:

Gaps where tiles should be
Tiles that appear uneven or out of line
Broken or cracked tiles on the ground

Missing or loose tiles leave your roof exposed, allowing water to seep in during the next rainfall.

2. Check for Leaks or Damp Inside Your Home

Roof damage doesn’t always show immediately on the outside. Often, the first signs appear indoors.

Check:

Ceilings for water stains or discolouration
Loft or attic spaces for damp patches
Walls near the roofline for bubbling paint or peeling wallpaper

Even a small leak can cause long-term structural damage if ignored.

3. Inspect Flashings and Roof Edges

Flashings (the metal strips around chimneys, vents, and roof joints) are designed to keep water out - but storms can loosen or bend them.

Warning signs include:

Lifted or missing flashing
Visible gaps around chimneys
Water staining near roof joints

Damaged flashing is one of the most common causes of post-storm leaks.

4. Don’t Forget Gutters and Downpipes

Storm debris can block gutters, causing rainwater to overflow back onto your roof or walls.

After a storm, check for:

Overflowing or sagging gutters
Detached or cracked downpipes
Large amounts of leaves or debris

Blocked gutters can lead to damp walls, rotting fascia boards, and roof edge damage.

5. Check Ridge Tiles and Roof Peaks

Ridge tiles (the tiles at the very top of the roof) are particularly vulnerable in strong winds.

Look out for:

Loose or missing ridge tiles
Cracks in mortar
Tiles that appear to have shifted

If ridge tiles fail, water can enter directly into the roof structure.

6. Be Careful - Safety First

It’s important not to climb onto your roof unless you’re trained and equipped to do so. Wet surfaces, loose tiles, and hidden damage can be extremely dangerous.

A visual check from ground level is usually enough to spot warning signs — anything more should be handled by a professional.

When to Call a Professional Roofer

If you notice any of the above issues - or even if you’re unsure - it’s best to get a professional inspection. What looks minor now can quickly become a major repair if left unchecked.

✅ Our advice:

A quick post-storm roof inspection can:

Catch small problems early
Prevent water damage and mould
Save money on larger repairs later

If you’d like peace of mind after a storm, we offer honest, professional roof inspections and repairs , with clear advice and no unnecessary work.

How to Spot Roof Damage Before It Becomes a Problem

Tue, 11 Nov 2025 10:16:38 GMT

Learn the early warning signs of roof damage - from cracked tiles to hidden leaks - so you can protect your home and avoid costly repairs.

Your roof is your home’s first line of defence against rain, wind, and the unpredictable UK weather. But like any part of your property, it needs attention. Spotting early signs of damage can save you thousands in repairs and prevent serious structural issues down the line.

Here’s how to recognise the tell-tale signs before they turn into bigger problems.

�� 1. Look for Missing or Cracked Tiles

Even a single cracked or missing tile can let in water, leading to rot and damp patches inside. Check your roof visually from the ground or with binoculars after heavy wind or storms.
If you see slipped or broken tiles, it’s time to call a professional roofer before leaks spread.

�� 2. Watch Out for Moss and Algae Growth

A little moss may seem harmless, but it traps moisture, slowly eroding roof materials and loosening tiles.
If your roof looks green or patchy, consider a safe cleaning or treatment service - never pressure wash tiles directly.

�� 3. Check Your Loft for Damp or Light

Head into your loft on a sunny day. If you see sunlight streaming through or notice damp smells, stains, or insulation that feels wet, water may already be seeping in.
Catching this early prevents mould, rot, and insulation damage.

�� 4. Examine Flashing and Chimneys

Roof flashing (the metal or sealant around chimneys and skylights) is a common weak point. Cracks or lifting in this area can quickly lead to leaks.
Re-sealing or replacing flashing is a simple, affordable job - if done early.

�� 5. Inspect Gutters and Downpipes

Overflowing or clogged gutters cause water to pool under tiles and damage fascia boards.
Clean them regularly, especially in autumn, and make sure water drains freely away from the house.

⚡ 6. Notice Interior Signs - Stains or Bubbling Paint

Brown ceiling stains, peeling wallpaper, or bubbling paint are classic symptoms of hidden roof leaks.
By the time these appear, the issue is often more advanced, so act immediately.

�� 7. Schedule Regular Roof Inspections

Most homeowners only think about their roof when something goes wrong.
At Bondright Roofing, we recommend a professional regular roof inspection, especially after severe weather. This helps spot hidden wear before it becomes visible damage.

✅ Final Tip: Prevention Is Always Cheaper

Replacing a few tiles or repairing flashing costs far less than re-roofing after prolonged neglect.
So, even if your roof “looks fine,” early maintenance can save you money and stress.

Emergency Call-Out in Henley-on-Thames: Rescuing a Storm-Damaged Slate Roof (and Undoing a Botched “Fix”)

Wed, 24 Sep 2025 06:36:26 GMT

When a sudden squall tore through Henley-on-Thames last week, a customer watched in panic as wind lifted slates and water was pouring into the loft because of sub-standard work carried out by a previous contractor. We took the call at 7:10 pm and were on site by 8:00 pm - harnesses on, roof ladders up, and a make-safe plan ready before the next band of rain hit.

What We Found on Arrival

Roof type: Natural slate (traditional nailed slate covering).
Storm damage: Missing and slipped slates on the windward slope, torn underlay, cracked battens, and water ingress to loft insulation.
Complication: A recent “repair” had been carried out by a contractor with no traceable registration or recognised accreditation . The methods used were not appropriate for a slate roof , leaving the area in significant disrepair. We rectified the unsafe elements, made the property watertight, and rebuilt the area to best practice.

Same-Evening Make-Safe

Our priority was to stop the water and eliminate hazards - properly. We:

Removed the unsafe patch and loose fragments the previous team left behind.
Installed a heavy-duty breathable temporary covering , fixed to sound timbers (not through the laps), with controlled, storm-resistant weighting.
Secured vulnerable courses of slate and set up internal drip protection to keep the ceiling dry overnight.
Result: The leak stopped that night, and the customer finally got some sleep.

Permanent Slate Repair (Next Day)

With a dry window in the morning, we completed a full, durable repair:

Strip-back to sound fabric: We carefully lifted the affected slate courses and ridge area to expose torn underlay and failed battens.
Renew the substrate: Replaced damaged battens to current best practice and fitted breathable underlay with correct headlaps.
Re-slate to match: Installed like-for-like natural slates , fixed with copper nails and stainless fixings where required, maintaining the correct nailing pattern and bond.
Storm-secure ridge: Upgraded to a mechanically-fixed dry ridge solution for better ventilation and wind uplift resistance (no mortar to crack or wash out).
Leadwork check: Re-dressed and sealed the lead at the abutment for a clean, watertight finish.
Runoff restored: Cleared gutters/valleys so storm water moves off the roof as designed.

Why the Previous “Repair” Failed

Membrane pierced: Nailing through underlay invites leaks.
Adhesives on slate: Mastic and random cement smears don’t substitute for correct slate fixing and laps.
No controlled laps/coverage: Wind can get under poorly lapped courses and lift slates again.
Water traps: Debris and smeared mortar blocked drainage paths, pushing water sideways into the roof.

The Outcome

By late afternoon, the roof was watertight, tidy, and more storm-resilient than before. Because the make-safe happened immediately, the ceiling below dried without staining.
We documented the before/after with photos for the customer’s records and insurance.

“ From panic to relief in a couple of hours. The first repair we’d been told was ‘done’ clearly wasn’t—but your team sorted everything properly, and the roof looks better than before the storm. ”
— J., Henley-on-Thames

Quick Tips for Slate Roofs Before/After Storms

Scan ridge lines and windward slopes for slipped or “fluttering” slates.
Keep valleys and gutters clear so water can’t back up into laps.
Avoid DIY patches and stop-gaps that pierce the membrane or trap water.
Consider dry-fix upgrades on exposed ridges for better wind resistance.
Book a rapid post-storm check - small slate issues escalate quickly in high winds.

Before you hire a roofer, check:

Company details: A real business name/number and a traceable address (Companies House listing if LTD/LLP).
Insurance: Current public liability insurance (ask for the certificate).
Trade affiliations: Membership of recognised bodies (e.g., NFRC) or written proof of competence.
Written scope & warranty: Clear specification, materials, and guarantees in writing.
References & reviews: Recent local jobs you can verify.

If you’re in Henley-on-Thames or nearby and a storm has hit your slate roof, we offer fast, professional make-safe call-outs followed by long-lasting, standards-led repairs . We’ll get you watertight - properly.

Why summer is when roof problems show up (and why that's good news)

Tue, 27 May 2025 16:32:00 GMT

Most roofs fail quietly. Summer is when the failures become visible, and that's the best time to fix them.

Roof problems rarely start in winter. They start months or years earlier, then winter buries the evidence.

Water gets into a hairline crack in the mortar around a chimney stack. Temperatures drop and that water freezes. Ice expands, but it doesn't move the mortar visibly. It just widens the crack a fraction. Come spring, the ice thaws, the water drains away, and from inside the house you notice nothing. The crack is now bigger, but you can't see it from the ground and there's no stain on the ceiling yet.

Missing or slipped tiles tell a similar story. In winter, the roof is usually wet. Moss is dark and swollen with moisture. Shadows are long. A tile that has dropped an inch out of alignment blends into the general texture of a damp, mossy surface. You'd have to be standing on a ladder to spot it.

Lead flashings around chimneys and dormers contract in cold weather. That contraction can temporarily close a gap that will reopen when temperatures rise. So a flashing that is failing may actually look watertight in January.

Winter gives a roof the benefit of the doubt. Summer removes it.

Why summer makes problems visible

Heat does three things to a roof, and all three are useful to know about.

Thermal cycling is the daily expansion and contraction of roofing materials as temperatures rise through the day and fall at night. In a British summer, a south-facing roof surface can reach 60°C or more in direct sun, then cool to 15°C overnight. That range, repeated day after day, puts stress on any joint, lap, or seal that is already compromised. Mortar that was borderline in April starts to crack and drop in July. Flashings that were holding on lift at the edges. Ridge tiles that were slightly loose begin to rock.

Drying is the second factor. Wet winters keep moss, mortar, and felt looking more intact than they are. Moisture holds things together temporarily. A dry June and July strips that away. Mortar that was saturated and soft all winter dries out and falls. You'll see it in the gutter, or in a small pile on the path below a chimney.

UV degradation works on flat roof membranes, felt underlays that have become exposed, and any plastic or rubber components. Ultraviolet light breaks down these materials over time, and the process accelerates in a hot, bright summer. Blistering on a flat roof surface, for example, is often only visible after a sustained warm spell.

Material movement ties all of this together. Slates, clay tiles, concrete tiles, and lead all move at different rates when heated. If fixings are corroded or pointing is weak, that movement is enough to shift things out of position. What looked fine in March looks different in June.

None of this is bad news. It just means summer is doing your inspection for you, if you know what to look for.

Four things to check from the ground right now

You don't need to go anywhere near a ladder. A pair of binoculars and ten minutes in the garden or street will tell you a great deal. These are the four areas worth looking at carefully.

Tile and slate alignment. Stand back far enough to see the whole roof slope as a surface. Tiles and slates should form consistent, even rows. Look for any tile that sits higher or lower than its neighbours, or one that appears to have rotated slightly. On older properties, particularly the Victorian and Edwardian semis common across Reading and Caversham, original clay tiles can slip when the nibs that hold them to the batten corrode or break. A single slipped tile in summer can become a water entry point by October.

Ridge condition. The ridge is the highest point of the roof, where two slopes meet. It is pointed with mortar, and that mortar takes more thermal stress than almost any other part of the roof. Look for gaps in the pointing, ridge tiles that appear to have shifted, or any section where the line of the ridge looks uneven. On the older detached properties around Sonning Common and Nettlebed, you often find ridge mortar that has been there for decades and is well past its useful life.

Lead flashings. These are the strips of lead that seal the junction between the roof and a chimney, a dormer, a parapet wall, or a roof light. In summer, look for any flashing that has lifted away from the masonry, or where the pointing that holds the top edge of the lead into the mortar joint has cracked or dropped out. Lifted flashings are one of the most common causes of water ingress in older properties, and they are often straightforward to spot from the ground if you know where to look.

Gutters and roofline. Gutters are not strictly part of the roof, but they tell you a lot about what is happening above them. Check for sagging, for joints that have separated, and for any plant growth in the gutter itself. In summer you can also look for tide marks on the fascia below the gutter, which indicate that water has been overflowing regularly. A blocked or broken gutter left through autumn and winter can cause damp in the walls below and accelerate rot in the fascia and soffit boards.

Why summer surveys produce better outcomes

Getting a professional roof inspection done in summer is not just about catching problems early. It also affects what happens next.

Roofing work requires dry conditions . Mortar needs time to cure without rain. Lead needs to be dressed at the right temperature. Felt and membrane work should not be done in wet weather. A summer survey that identifies a repair means that repair can be scheduled and completed in good conditions, with the work fully cured and weathertight before the autumn rains arrive.

Materials are also more readily available. Matching tiles and slates, specialist lead, heritage clay products for conservation properties in Henley and the surrounding villages, all of these are easier to source when you are not competing with the post-storm rush that hits every October and November. In 40 years of working across the Thames Valley, the pattern at Bondright is consistent: the homeowners who call in summer get the work done properly, on their schedule.

The ones who wait until a leak appears in November are often working against the weather.

Scaffold, where it is needed, also tends to be more available and easier to plan in summer. The autumn rush for roofing contractors across Berkshire and South Oxfordshire is real, and it compresses lead times significantly.

A summer survey costs nothing. The information it gives you is worth a great deal.

If anything in this post matches what you have been looking at on your roof, the right next step is a professional roof inspection while conditions are good. Bondright's free roof survey includes a full photographic report of everything we find, sent to you in writing, with no obligation attached. If there is nothing wrong, you will know that. If there is something to address, you will have time to plan it properly and get it done before the weather turns. Our roof repair services are there when you need them, but the survey comes first. Book yours now, before the autumn rush begins.

The five most common roof problems we see in early summer (and what each costs to fix)

Wed, 19 Feb 2025 10:59:00 GMT

By mid-June, every roofer in the area has a pattern for what they're being called out for. Here's ours from this summer so far. Five problems keep coming up, in roughly the same order of frequency, and each one has a predictable cost range. If you've spotted something on your roof and you're trying to work out what you're dealing with, this should help.

This is the one we see most of all right now. Roofing tiles expand in heat and contract when temperatures drop overnight. After a sustained warm spell, that movement puts stress on the nibs, the small hooks that hold each tile in place on the batten. Older tiles, particularly plain clay or concrete tiles on roofs laid in the 1970s and 1980s, are the most vulnerable.

A slipped tile doesn't always mean a leak straight away, but it creates an opening for water to get under the surrounding tiles. Once that happens, the felt underneath takes the load, and felt doesn't last indefinitely.

Cracked tiles are a slightly different problem. Thermal stress causes fine cracks that are almost invisible from the ground but let water through every time it rains. The crack wicks water in, and the first sign is often a damp patch on a ceiling directly below.

The repair cost depends on how many tiles are affected and how accessible the roof is. A single slipped tile on a straightforward pitch might be £150. A run of cracked tiles on a steeper roof with limited access can reach £400. Our roof repair services cover both.

A recent customer in Sonning Common had three cracked clay tiles on the rear slope of their Victorian terrace. The ceiling below had a faint tide mark. We replaced the tiles and resealed the surrounding area. Job done in a morning.

HChimney flashings are the strips of lead that seal the joint between the chimney stack and the roof surface. They're doing a difficult job: bridging two structures that move independently, in all weathers, year after year.

Early summer is when we tend to find them, because the drier weather lets us see the damage clearly and get up there safely. But the failure usually happened over winter. Frost gets into a hairline crack in the mortar that holds the flashing in place, the mortar spalls away, and the flashing lifts. Once it lifts, rain drives in behind it.

The result is water tracking down the inside of the chimney breast, often appearing as a damp stain on the wall or ceiling of an upstairs room. Sometimes it looks like condensation. It isn't.

A typical chimney flashing repair, re-pointing the stepped flashings and re-dressing the lead, runs from £450 to £900 depending on the size of the stack and how much of the flashing needs replacing. If the chimney is tall or awkwardly positioned, access equipment adds to that.

A property on the Reading Road in Henley had both side flashings detached and the back gutter flashing almost entirely lifted. The internal damage was significant enough that the homeowner had assumed it was a plumbing leak. It wasn't. Total repair was within the range above.

We work to Lead Sheet Training Academy standards on all lead and heritage work, which matters particularly on older chimneys where the original lead was laid to a high specification and deserves to be matched properly.

Gutters seem like a minor item until they fail, and then the consequences can be serious. A blocked gutter in early summer is usually full of the debris that fell through autumn and winter and has been sitting there ever since. Moss, leaf matter, and silt compact into a plug that holds water against the fascia board. The fascia rots. The water overflows and runs down the wall.

A detached gutter, one where the bracket has pulled away from the fascia, causes a different problem. Water pours down the face of the building rather than being carried to the downpipe. On an older property with a solid masonry wall, that steady wetting can eventually cause damp internally.

A gutter clear is the most straightforward job on this list: typically £80 to £150 for a standard semi-detached. If the gutters need re-fixing or a section needs replacing, you're looking at £150 to £250. More extensive work on a larger property costs more. Our guttering repair service covers clearing, re-fixing, and full replacement of gutters, fascias, and soffits.

A 1960s semi in Tilehurst had a rear gutter that had sagged and detached at two brackets. The overflow had been running down the wall for long enough to cause efflorescence on the brickwork. The gutter repair was straightforward. The brickwork needed separate attention.

Dormers and bay windows both have lead aprons, flat sections of lead that sit at the base of the vertical face and lap onto the roof surface below. They're a common weak point because the lead has to flex around angles, and older lead that was dressed by hand rather than machine-formed can develop splits over time.

In summer, the heat causes lead to expand noticeably. If the lead wasn't installed with adequate drips and rolls to allow for movement, it eventually splits or lifts at the edge. Water then gets into the joint between the dormer and the roof, which is one of the harder places to trace a leak from.

Signs to look for: damp patches on the ceiling directly below a dormer, or water marks on the internal wall of a bay window room at first-floor level. The damage is often slow and cumulative, which means by the time you notice it, water has been getting in for some time.

Repair costs typically fall between £350 and £700, depending on how much lead needs to be replaced and whether the underlying timber has been affected. Where the substrate has rotted, that adds to the scope. Again, we work to Lead Sheet Training Academy standards here.

Forty years of working across the Thames Valley means we've seen this problem on everything from 1930s bay-fronted semis in Caversham to newer dormer extensions in Woodley. The failure mode is the same. The fix is the same.

Most modern single-storey extensions have a flat or low-pitch roof finished in either GRP (fibreglass) or felt. GRP is the more durable of the two, but it isn't indestructible. Felt roofs have a shorter lifespan and are more vulnerable to thermal movement.

Early summer is when flat roof problems announce themselves. The heat causes the surface to expand, and any existing weakness, a poorly sealed joint, a blister in the felt, a crack around a pipe collar, opens up. You might not notice it until the next rain, but when rain comes, the water finds the gap.

A repair to a localised crack or blister on a GRP roof typically costs between £200 and £600, depending on the size of the affected area. A felt repair is in the same range but may only buy you a few more years if the felt is already near the end of its life.

Full replacement is a different conversation: £2,500 to £6,000 for a typical single-storey extension roof, depending on size and the system specified. GRP replacement is at the higher end but lasts significantly longer. Our flat roof repair service covers both repair and full replacement.

From the ground, it's hard to tell. A damp patch on a ceiling could be a cracked tile, a failed flashing, or a flat roof blister. They look similar from inside the house but need completely different fixes.

The most useful thing you can do is get eyes on the roof before you call anyone for a quote. We offer a free roof check with a full photographic report. You'll know exactly what's there, what needs doing, and what it's likely to cost, before any work starts.

If you think you have an active leak or something that needs attention urgently, get in touch and we'll prioritise a visit.

Lead flashing in summer: why heat reveals failures that winter hid

Mon, 28 Oct 2024 00:13:00 GMT

Lead expands in heat and contracts in cold. Over a hot summer, it does both several times a day. That's when failures show up.

Lead flashing is the metal seal between your chimney and your roof. Without it, water finds a direct path into the gap where masonry meets tiles or slates, and from there into your ceiling.

It sits in several places around a chimney stack. The apron flashing covers the front face, where the chimney meets the slope below it. Step flashings run up each side, stepping with the tile courses. The back gutter sits behind the stack, collecting water that runs down from above and directing it away to either side.

On older properties, you'll also find lead soakers tucked under each individual slate or tile at the sides. These are thin pieces of lead, hidden from view, that work alongside the step flashings.

In the Henley conservation area, and across period houses throughout the Chilterns, lead is the standard material for all of this work. There's no substitute that performs as well over decades. It moulds to irregular shapes, it's durable, and when installed correctly it outlasts the building around it.

The problem is that "installed correctly" matters enormously. And a lot of lead on older roofs was not installed to modern standards, or has simply reached the end of its working life.

Why summer is when weak lead fails

Lead is a soft metal. That's part of what makes it useful. It can be dressed to fit complex shapes and it doesn't corrode the way steel does. But that softness also means it moves.

In direct summer sun, a south-facing chimney apron can reach 80°C or higher. At night, the same piece of lead drops back toward ambient temperature. That's a swing of 50°C or more in a single day. Lead expands at roughly 29 millimetres per metre for every 10°C of temperature change. On a long run of flashing, that movement is significant.

Over years, this thermal cycling puts stress on any point where the lead is restrained. A mortar joint that was tight in February becomes a weak point in July. The lead wants to move; the mortar holds it in place. Something has to give. Usually it's the bond between lead and mortar, or the lead itself develops a crack at the point of stress.

Summer also softens the lead slightly, making it more vulnerable to physical stress. A heavy rainfall after a heatwave, with cold water hitting metal that's been baking all day, adds a thermal shock on top of the existing stress.

Oxidation plays a role too. Lead develops a patina of lead carbonate over time, which actually protects it. But where that patina is disrupted, by movement, by poorly applied coatings, or by abrasion, the underlying metal is more exposed. Long hot summers accelerate that process.

The result is that problems which were dormant through winter, perhaps sealed by debris or frost-swollen mortar, open up in summer and let water in. A damp patch that appears in June or July is often a lead failure that's been developing for years.

Splits at the chimney apron. The apron is the largest single piece of lead on most chimney stacks. It covers the full width of the front face and tucks under the tiles or slates below. Because it's a large piece, it moves more in total than smaller sections. Splits tend to develop across the width, often near the top where the lead is tucked into the mortar joint. Once a split opens, water tracks straight down the face of the chimney and into the roof space.

Separation from mortar bedding. Lead flashings are held at the top by being tucked into a raked mortar joint and then pointed over with fresh mortar. Over time, the mortar breaks down, the bond fails, and the top edge of the flashing lifts away from the masonry. You may be able to see this from ground level on some stacks, a visible gap or a section of lead that's pulling away from the brick. Water enters at the top and runs behind the flashing rather than over it.

Lifted step flashings. Step flashings on the sides of a chimney are particularly vulnerable to thermal movement because each piece is relatively short and is fixed at both ends. When the lead expands, it has nowhere to go. Over time, the fixings work loose or the mortar fails, and individual steps lift away from the chimney face. On 1900-1930s Reading semis, lifted step flashings are the most common chimney fault we see. The houses are the right age, the original lead is at or past its design life, and the chimneys often face south or west.

Fatigue cracks along the back gutter. The back gutter sits in a confined space between the rear of the chimney and the rising slope of the roof. It collects a large volume of water and it's subject to constant thermal movement. Fatigue cracks, fine hairline splits caused by repeated expansion and contraction over many years, develop along the length of the gutter. These are difficult to spot without getting close to the stack, but they allow steady water ingress even in moderate rainfall.

When a homeowner spots a gap or a crack in lead flashing, the instinct is often to reach for a tube of silicone sealant. It's quick, it's cheap, and it looks like it fills the gap. It doesn't work.

Silicone doesn't bond reliably to oxidised lead. It can hold for a few weeks, sometimes a few months, but it has no flexibility to match the thermal movement of the lead beneath it. When the lead expands in the next heatwave, the silicone breaks away. Often it peels back and creates a channel that directs water into the joint rather than away from it.

More importantly, silicone hides the underlying problem. A split in an apron or a failed mortar joint needs proper repair. Covering it with sealant delays that repair and usually makes it worse by the time a roofer eventually opens it up.

There is no sealant-based fix for lead flashing that holds long-term. The lead needs to be repaired or replaced.

Correct lead flashing work starts with the right material. For chimney flashings, the minimum is code 5 lead, which is 1.8 millimetres thick. Code 4, at 1.25 millimetres, is sometimes used for soakers, but code 5 is the standard for any exposed flashing. Thinner material is more vulnerable to fatigue and thermal damage.

Laps between sections need to be correct. A minimum 100mm lap prevents water from tracking back through the joint by capillary action. The lead is dressed into a raked mortar joint, fixed with lead wedges, and pointed with a mortar mix that allows slight movement rather than locking the lead rigid.

On any run longer than 1.5 metres, expansion joints are formed by overlapping sections rather than running a single piece. This gives the lead room to move without building up stress at a fixed point.

All of our lead work follows Lead Sheet Training Academy standards and complies with British Standard 5534 . We've been doing this work for 40 years, across everything from Victorian terraces in Reading to listed properties in the Henley conservation area. Our heritage roofing experience covers churches, listed buildings, and complex chimney stacks where the lead work is as much about preservation as waterproofing.

The difference between a repair that lasts 20 years and one that fails in two comes down to the standard of the original installation.

If you've noticed a damp patch, a stain on a chimney breast, or water appearing after rain, don't leave it. Summer is the right time to get eyes on the lead while failures are visible. Book a free chimney inspection and we'll provide a full photographic report of the chimney and lead work, so you know exactly what you're dealing with before any work starts. If you have an active chimney leak repair that needs urgent attention, get in touch and we'll prioritise it.

Flat roof repairs in summer: what we check and why heat damage is often invisible from below

Wed, 18 Sep 2024 22:38:00 GMT

Most flat roof failures start at the top and only reach the ceiling months later. By the time you see a damp patch, the surface has usually been compromised for a season.

That gap between cause and symptom is what makes flat roofs awkward. You can be looking at a roof that is already failing and see nothing obviously wrong from street level. Summer makes this worse, not better. Heat accelerates the damage while making the surface look dry and intact.

This post explains what actually happens to a flat roof in summer, what we look for when we inspect one, and how we decide whether a patch or a full replacement is the honest answer.

Why flat roofs fail in summer specifically

Heat is not kind to a flat roof. Several things happen during a sustained warm spell, and they tend to compound each other.

UV degradation works slowly but continuously. Ultraviolet light breaks down the surface layer of a flat roof over time, making it brittle and less resistant to water. You cannot see this from below. The surface may look intact from a ladder glance, but close inspection will show cracking, crazing, or a chalky texture that tells you the waterproofing layer is losing its integrity. A summer of strong sun accelerates this process considerably.

Thermal expansion is a less obvious problem. A flat roof surface heats up significantly during the day, sometimes reaching temperatures well above ambient air temperature. It then cools overnight. That daily cycle of expansion and contraction puts repeated stress on seams, joints, and the points where the surface meets upstands, edge trims, and flashings. Over years, those stress points open up. Water finds the gaps.

Ponding and residue compound the problem. Flat roofs are designed with falls to drain water away, but those falls can become compromised over time as the substrate settles or the surface loses its shape. Water that sits on the roof during summer rain does not always evaporate cleanly. It leaves behind mineral deposits and debris that sit in the low points, holding moisture against the surface and accelerating deterioration. In a wet summer this becomes a cycle that does real damage to the waterproofing layer.

The result is a roof that can look reasonable from below while being significantly compromised above. By the time a damp patch appears on your kitchen ceiling or the plasterboard in your garage starts to stain, the surface has usually been failing for months, sometimes longer.

What we check on a flat roof survey

A proper flat roof inspection is methodical. We work across the whole surface, not just the area directly above a reported problem. Flat roof water ingress frequently travels before it drops, so the entry point is often not directly above the damp patch.

Surface condition is the starting point. We look at the overall texture and appearance of the waterproofing layer, checking for cracking, crazing, blistering, or areas where the surface has lifted. Blistering is common in summer: air or moisture trapped beneath the surface expands in the heat and creates bubbles. Some blisters are superficial. Others indicate delamination of the surface from the substrate below.

Seam integrity is checked carefully. Seams and laps are the most common entry points for water. Heat cycling opens them over time. We check that every seam is bonded, that there is no lifting at the edges, and that the lap widths are adequate.

Edge trims and upstands get close attention. The junction between the flat roof surface and any vertical element, whether that is a parapet wall, a raised edge trim, or the base of a chimney, is a high-risk area. The surface has to turn up and bond to something solid. If that bond fails, or if the trim itself has corroded or pulled away, water gets in at the perimeter.

Outlets and drainage are inspected for blockage and condition. A blocked outlet creates ponding. A corroded or poorly sealed outlet creates a direct water path into the roof structure.

Parapet flashings , where present, are checked for mortar condition, flashing continuity, and any signs of movement. A parapet flashing that has lifted even slightly can allow significant water ingress during heavy rain.

The substrate below the surface , where visible at edges or access points, tells us whether damage has already reached the structural layer. Soft or wet decking boards, staining on the underside of the deck, or visible rot are all signs that water has been getting in for some time.

This matters when deciding whether a patch will hold or whether the deck itself needs attention.

We cover all of this in a free photographic inspection report. Every finding is photographed and noted so you can see exactly what we have found, not just take our word for it. This is standard practice for us across the Thames Valley, whether we are looking at a 1960s extension in Reading or a kitchen roof on a period property in Henley-on-Thames.

When patching is the right call

Patching makes sense when the failure is localised and the rest of the surface is sound.

A single seam that has opened, a blistered area that has not delaminated the wider surface, an outlet seal that has failed, a flashing that has lifted at one point. These are all repairable without replacing the whole roof.

The condition of the surrounding surface matters here. If the surface around the damaged area is still flexible, bonded, and showing no signs of widespread UV breakdown, a well-executed repair will hold.

We are straightforward about this. If a patch is the right answer, we will tell you. We have been doing roof repairs across this area for 40 years and we have no interest in selling a full replacement to someone who does not need one. A repair done properly is a good job. A repair done on a surface that is already failing across most of its area is money spent twice.

The honest position is that patching works well on a roof that has one problem in an otherwise sound surface. It does not work well as a repeated sticking plaster on a roof that is deteriorating generally.

When the whole roof needs replacing

Some roofs are past the point where targeted repairs will give you a reliable result.

Widespread surface failure is the clearest indicator. If cracking, crazing, or delamination covers most of the surface rather than one localised area, patching one section leaves the rest of the roof still failing. You will be back within a year or two with a new problem.

Ponding across the whole roof suggests that the falls have been compromised, often because the deck below has moved or deteriorated. Fixing the surface without addressing the falls means the water will continue to sit and continue to do damage. This is common on older garage roofs and extensions across the area, particularly those built in the 1960s and 1970s when flat roof construction methods were less refined.

Substrate damage changes the calculation significantly. If the decking boards below the waterproofing layer are soft, rotten, or structurally compromised, a new surface laid over them will not perform correctly. The deck needs to be right before the waterproofing goes down. When the substrate is damaged across a significant area, a full replacement is the only way to get a roof that will last.

Multiple past repairs on the same roof are a signal too. If a roof has been patched repeatedly and is still letting water in, the surface has reached the end of its serviceable life. The repairs are no longer keeping pace with the deterioration.

In these cases, a full replacement gives you a roof that will perform reliably for years rather than a series of repairs that each buy a little more time.
