A GRP fibreglass roof is meant to give you one seamless, waterproof surface with no joints for water to creep through. When the gel coat starts to craze, a resin layer cracks, or a section begins to lift, fibreglass roof repair in Melton Mowbray needs to match the actual fault, not just hide it under fresh topcoat. Tate & Sons Roofing repairs GRP roofs across Melton Mowbray and the surrounding villages, from a single hairline crack on a garage roof to a full recover on a house extension.
This page covers the warning signs, how we tell a cosmetic crack from real delamination, what repair day looks like, and honest cost ranges. If your flat roof is felt or rubber rather than fibreglass, our flat roof repair page covers those systems instead. Either way, we're the roofing contractor across Melton Mowbray people call first when a flat roof starts letting water in.
Spot the Warning Signs Before a Small Crack Becomes a Leak
Most GRP roofs give clear warning before they let water through. The signs are easy to miss from ground level, though, especially on a garage or extension roof you rarely look at closely.
Look out for:
- Fine, spider-web cracks in the top coat — this is gel coat crazing
- Deeper, straighter cracks that follow a stress line or upstand
- Bubbles or blisters where the surface has lifted slightly
- Soft, spongy patches when you walk the roof carefully
- Dark staining or a chalky, faded finish after years in the sun
- Water stains on a ceiling below a flat-roofed extension
We see a good number of these roofs on garages and single-storey extensions across Melton Mowbray, particularly ones backing onto Melton Country Park, where mature trees drop debris that blocks outlets and lets water sit. Standing water is one of the fastest ways to turn a small gel coat crack into a proper leak. A roof that looks fine from the garden can still be failing at the upstands and edge trims, which is why we check the whole surface, not just the middle of the roof.
Gel Coat Crack or Structural Delamination — Getting the Diagnosis Right
Not every mark on a fibreglass roof means the same thing, and treating a serious fault as a cosmetic one wastes your money. Gel coat crazing is a network of fine surface cracks in the top coat only. It looks worse than it is, and on its own it rarely lets water through straight away.
A resin crack runs deeper, usually along a stress point such as an upstand, corner, or old repair edge. Left alone, it lets water reach the fibreglass matting underneath, and that is when real trouble starts. Delamination is more serious again — the layers of the laminate separate from each other, or from the timber deck below, and the roof develops a soft, springy feel underfoot.
Deck movement is the most common root cause we find on older Melton Mowbray properties, often from timber that was never quite dry enough when the roof was first laid. Wind-driven water gets forced under edge trims on exposed sites, and freeze-thaw cycles push trapped moisture further between the layers each winter. Properties out toward the Vale of Belvoir Scarp take a harder battering from wind than a sheltered garden roof in town, which speeds up crazing and edge failure on exposed extensions. Poor original falls that leave water sitting on the roof make every one of these problems worse — the Single Ply Roofing Association's guidance on flat roof drainage and falls sets out why standing water shortens the life of any flat roof covering, GRP included. A free drone survey shows us exactly which fault we're dealing with before we recommend a fix.
Repair, Resin Overlay or Full Recover — Choosing the Right Fix
Three options cover almost every fibreglass roof problem we see around Melton Mowbray. Which one suits your roof depends on how much of it is affected, and whether the deck underneath is still sound.
A crack or gel coat repair grinds back the damaged area, adds fresh resin and matting where needed, then finishes with new topcoat. A resin overlay goes further, bonding a new resin and topcoat layer across the whole existing roof without stripping it back, which suits an ageing roof with crazing spread over a wide area. A full recover strips the roof back to the timber deck and rebuilds it from scratch, which is the right call once the deck itself is soft, wet, or delaminated.
| Option | Typical cost | What it involves | Best for |
|---|---|---|---|
| Crack / gel coat repair | £150–£500 | Grinding back the damaged area, resin and matting reinforcement, new topcoat | Isolated cracks or crazing on a roof with a sound, dry deck |
| Resin overlay | £600–£1,800 | New resin and topcoat bonded over the existing laminate, no strip-out | Widespread crazing or several small cracks, deck still stable |
| Full recover | £70–£110 per m² | Full strip to the deck, timber repairs, new laminate and topcoat | Delamination, soft or spongy decking, roofs past 20 years old |
On the newer, higher-spec homes around Old Dalby, we increasingly fit and repair walkable GRP roof terraces, which need a thicker, non-slip topcoat rated for regular foot traffic rather than the standard finish used on a garage roof. Repairing a walkable terrace the same way as an ordinary flat roof risks a surface that looks fixed but isn't safe to stand on. If your roof needs a full new fibreglass covering rather than a patch or overlay, our GRP fibreglass roofing service covers a complete new installation.
What Happens on Repair Day, Start to Finish
A fibreglass roof repair follows the same order on every job, whether it's a small garage roof in Melton Mowbray or a larger terrace out at Frisby on the Wreake.
Here's what to expect:
- The roof is inspected and the damaged area marked out
- Loose or damaged gel coat and laminate is ground back to sound material
- The area is left to dry fully — GRP will not bond over damp material
- Fresh resin and chopped strand matting are laid into the prepared area
- A matching topcoat is applied once the resin has cured
- Edge trims and upstands are checked and resealed where needed
- The finished repair is inspected before we leave site
Most isolated crack or gel coat repairs take half a day to a full day. A resin overlay across a whole garage roof usually takes one to two days, and a full recover on a typical extension runs two to four days depending on size and deck condition. Temperature matters more with GRP than with most other materials — resin needs a dry surface and a reasonable temperature to cure properly, so we plan repairs around the weather rather than rushing a job in damp or near-freezing conditions.
What Fibreglass Roof Repair Really Costs in Melton Mowbray
Cost depends on how much of the roof is damaged, how easy the roof is to access, and the condition of the deck underneath. As a general guide, a small gel coat or crack repair on a garage roof typically runs £150–£500. A resin overlay across a wider area of crazing usually costs £600–£1,800. A full recover, where the roof is stripped back to the deck and rebuilt, runs £70–£110 per square metre, so a typical 15–20m² garage roof often lands between £1,200 and £2,200.
What pushes a price up or down:
- Size of the damaged area — one crack costs far less than crazing across the whole roof
- Deck condition — rotten or soft timber under the laminate adds repair cost before any new GRP goes on
- Access — a garage roof reached by ladder costs less to work on than a terrace needing scaffold
- Colour matching — matching an existing topcoat colour can add a little over standard grey
- Walkable spec — terraces and balconies need a thicker, textured topcoat that costs more per square metre
- Weather delays — resin needs the right temperature and a dry surface to cure, and winter jobs sometimes need extra site visits
We see the full range of these jobs across the borough, from straightforward garage roofs in Asfordby to larger terrace repairs on bigger properties out toward Harby. These are general market ranges, not a quote for your roof. A fixed price needs a survey.
Keep Your Fibreglass Roof Sound for Years to Come
A well-fitted GRP roof can last 20 to 30 years, but only if small problems get caught early. Gel coat crazing that's left alone eventually lets water through, and a small resin crack rarely stays small.
A few simple habits keep a fibreglass roof performing across its full lifespan:
- Clear leaves and debris from the surface and outlets each autumn
- Check for standing water 48 hours after heavy rain — it should have drained away
- Look over upstands, edge trims and any pipe collars once a year
- Get crazing or hairline cracks looked at before they spread
- Book a free drone survey every few years, or after a bad storm
None of this needs specialist tools, just a regular look and a call to us if something seems off. We check roofs like this across Melton Mowbray all year round, and catching a hairline crack early is always cheaper than dealing with a delaminated deck later.
Why Melton Mowbray Homeowners Trust Tate & Sons With Their GRP Roof
Fibreglass roofing rewards a roofer who does the groundwork properly, and punishes one who doesn't. Daniel Oakland, our project manager, has more than twenty years in the trade and specialises in GRP alongside EPDM and standing-seam systems. He grinds back and preps every repair himself on larger jobs, because a GRP repair is only as good as the surface it's bonded to.
Founder James Tate started the business after fifteen years working roofs across Melton Mowbray and the East Midlands, and still prices most jobs himself. He built Tate & Sons around a simple idea — find out what's genuinely wrong, use the right materials, and stand behind the result.
That's why we diagnose before we quote, rather than reaching for the same fix on every roof. Between us we carry over 40 years of combined team experience, hold NVQ Level 2 and 3 qualifications in Roofing Occupations, and hold CSCS cards. Janice Whitmore, our office manager, keeps you posted from your first call through to the finished repair.
Every repair comes with our 10-Year Workmanship Guarantee, backed by a team that repairs fibreglass roofs across Melton Mowbray every week, not once in a while. Read more about the people behind the work on our About Tate & Sons Roofing page.

Got Questions?
Your Fibreglass Roof Repair Questions, Answered
Can a fibreglass roof be repaired, or does it need replacing?
Most fibreglass roof problems can be repaired rather than replaced. If damage covers less than around a quarter to a third of the roof, a targeted repair or resin overlay is usually the more cost-effective route. Replacement becomes the better option once the timber deck underneath is soft, wet, or delaminated across several areas. A free drone survey tells you which category your roof falls into before any work is agreed.
What causes cracks and crazing in a GRP roof?
Cracks and crazing usually come down to movement, weather, or an original installation that wasn't quite right. Deck movement, thermal expansion, and UV exposure all put stress on the laminate over time. Trapped moisture and poor detailing around trims or outlets create weak points that crack first. Roofs laid on plywood rather than OSB decking are also more prone to poor adhesion and early cracking.
How much does fibreglass roof repair cost in Melton Mowbray?
A small crack or gel coat repair typically costs £150–£500, a resin overlay across a wider area runs £600–£1,800, and a full recover costs £70–£110 per square metre. The final price depends on the size of the damaged area, the condition of the deck, and how easy the roof is to access. These are general market ranges rather than a quote for your specific roof. A fixed price always needs a survey.
How long does a GRP roof repair take to cure?
Resin typically cures within a few hours in good conditions, though full hardness can take a day or two. Cold or damp weather slows curing considerably, and GRP will not bond properly onto a damp surface at all. That's why we check both the forecast and the moisture level in the roof before starting any repair. A repair rushed in the wrong conditions is far more likely to fail early.
Can fibreglass roof repairs be done in cold or wet weather?
Repairs are possible in cooler weather, but the roof needs to be dry and the temperature needs to be reasonable for the resin to cure properly. Applying GRP in damp or near-freezing conditions is one of the most common causes of early repair failure. We plan repairs around a dry weather window rather than working to a fixed date regardless of conditions. Where a leak needs an urgent temporary fix, we can make the roof watertight and carry out the full repair once conditions allow.
What's the difference between gel coat crazing and structural delamination?
Gel coat crazing is a network of fine cracks in the top coat only, and it's largely cosmetic in the short term. Delamination is far more serious — it means the layers of the laminate have separated from each other or from the deck below, leaving a soft or springy feel underfoot. Crazing left unrepaired can eventually let water through and lead to delamination over time. Telling the two apart accurately is the main reason a proper inspection matters before any repair is quoted.
Why does a GRP roof crackle or flex underfoot without a visible crack?
A roof that flexes or crackles underfoot without an obvious crack usually points to an early-stage deck or bonding problem rather than a surface fault. It can mean the laminate has started to separate from the timber deck beneath it, even though the top coat still looks intact. Left unchecked, this kind of movement usually shows up as a visible crack or leak within a season or two. It's worth having checked even when there's nothing to see from the surface.
Does wind off the Vale of Belvoir Scarp make gel coat crazing worse on exposed roofs?
Yes, more exposed sites do tend to show crazing and edge wear earlier than sheltered ones. Properties out toward the Vale of Belvoir Scarp take a harder battering from wind-driven rain than a garden roof tucked in behind other buildings in town. That extra exposure stresses the gel coat and pushes water harder against edge trims and upstands. We factor a property's exposure into the repair specification, not just its postcode.
Do Old Dalby's walkable GRP terraces need a different repair spec to a standard garage roof?
Yes, a walkable terrace needs a thicker, textured, slip-resistant topcoat rated for regular foot traffic, not the standard finish used on a garage or extension roof. Repairing a walkable terrace with an ordinary topcoat can leave a surface that looks fixed but isn't safe or durable to stand on. We see more of these terraces on the newer, higher-spec homes around Old Dalby, and we spec the repair to match how the roof is actually used. Getting this detail right the first time avoids a repeat repair within a year or two.
