Fibreglass Roofs in Finchley, Harringay, and Across London
While more complicated than an EPDM rubber roof, fibreglass is another method of finishing a flat roof that proves very popular among our London clients. Applied as a liquid resin, it can take the shape of even the most unusual roof. When it cures, it sets as a hard, durable and – most of all – watertight layer across your flat roof, ensuring years of use. With forty years in the business, ABC Roofing Company London can be relied upon to deliver quality fibreglass roofing solutions every time.
Expert Fibreglass Roof Installation
Installing a fibreglass roof begins with stripping your existing roof right down to the joists. We inspect the support structure for signs of deterioration or damage, replacing any timbers that we consider too far gone. On top of the joists, we lay a roof deck comprising thick and sturdy OSB boards, sufficient to take the weight of the fibreglass resin, plus any expected foot traffic on the roof.
The fibreglass is applied in layers as liquid treatments. We attach edge trims to the end of your flat roof to prevent run off, before pouring in a fibreglass resin, followed by a scratch mat and a laminate layer. Each section has to dry before the next can be applied, which makes this process longer than simply sticking down an EPDM rubber sheet.
The final layer is another layer of fibreglass resin, only this one includes a curing agent that speeds up the hardening process as it dries. The finished product is hard to the touch, scratch- and scuff- resistant, highly durable, and completely watertight.
Reliable Fibreglass Roof Maintenance and Repairs
As tough as fibreglass roofing is, on occasions it can be damaged, usually as a result of impact damage from an outside source – a falling tree branch, perhaps, or someone dropping a heavy item while standing on the roof. This kind of damage is easy enough to repair, as we seal any cracks or divots in the fibreglass shell with the same protective resin.
In terms of maintenance, a fibreglass roof requires very little. A brief inspection once a year to sweep up any dead leaves that might have been collected is normally enough.

The Benefits of
Fibreglass Roofing
The primary advantage of choosing fibreglass is that it forms an unbroken, seamless shell across the whole structure. Traditional flat roof coverings rely on joins or overlapped seams that eventually lift or let water in, especially with the weather shifts common across Finchley and Haringey. GRP cures into a rigid composite sheet that standing water simply cannot penetrate. Beyond its waterproofing qualities, it is tough enough to walk on, making it a brilliant option for balcony spaces or roofs that need regular access. It also looks clean and tidy, giving extensions, garage tops, and dormer windows a crisp finish that holds up against sun exposure without cracking or blistering.

Maintenance and Repairs
GRP flat roofs need very little attention to stay in top shape, though keeping them clear of garden debris is always a good idea. In tree-lined neighbourhoods across Finchley and Haringey, autumn leaves and moss can block gutters, forcing water to pool longer than it should. Sweeping off wet leaves once in a while and ensuring drainage outlets stay clear is usually all it takes. If a roof does get damaged, perhaps from a heavy tile slipping off a main pitch or a falling branch, you rarely need a full re-roof. We sand down the area around the fracture, check that the timber deck beneath remains dry, and laminate a fresh glass-mat patch directly over the break before applying a matching topcoat to seal it completely.
FAQs
GRP roofing combines liquid resin with glass-fibre matting to form a rigid laminated covering. Once the layers have cured, a protective topcoat completes the surface. The result is a continuous finish shaped around the roof deck, edges and details rather than a covering supplied as one flexible sheet.
Fibreglass cures into a rigid surface, so it needs a sound, stable deck beneath it. Rotten, weakened or uneven boards can affect the finished roof and should be dealt with first. ABC Roofing Company London strips the existing covering, checks the supporting structure and replaces unsuitable timber before laying the new deck.
Because the resin and matting are applied on site, GRP can be formed around corners, upstands and other details on many irregular flat roofs. Careful preparation remains essential, particularly where the roof meets walls, outlets or rooflights, because these changes in level must be incorporated into the waterproof system.
Yes. A GRP system is built in stages, and the relevant layer must be ready before the next treatment is applied. Temperature and weather can influence curing conditions, so installation needs to be planned around a suitable forecast rather than rushed simply to complete the roof more quickly.
Fibreglass is hard-wearing, but a strong impact from a branch, dropped tool or other heavy object can crack or chip the surface. Damage should be examined before water reaches the deck. Localised defects can often be repaired using compatible resin and reinforcement without replacing the entire covering.
Use a soft brush and avoid sharp tools that could mark the protective topcoat. Pay particular attention to outlets and gutters, where collected leaves may hold water back. An annual visual inspection is generally sensible, although roofs beneath trees may need debris removed more frequently.
