Fibreglass Roofs in Barnet
If you are looking for a long-lasting fibreglass roof in Barnet, you can count on the team at ABC Roofing Company (London) Ltd.
GRP, or glass-reinforced plastic, gives you a completely solid outer skin over a flat structure. Because resin and matting cure together into one unified sheet, there are no seams for water to seep through when rain sits on the roof during wet North London winters.
We fit new GRP systems and repair existing ones all across Barnet, working on residential extensions, garages, and commercial properties. Over the years, we have built our reputation on straightforward work that looks neat and holds up for decades without fuss.
GRP Fibreglass Roofing in Barnet
Unlike traditional felts that can crack along the joints as temperatures rise and fall, a fibreglass covering creates a single continuous shield across the whole timber deck. We work with domestic homeowners, landlords, and local business owners right across Barnet. Every roof gets assessed carefully on its own merits so we lay down the right resin buildup and trims to handle whatever the weather throws at it.
Fibreglass Roof Installation in Barnet
We always start by getting up on the roof to inspect the underlying timber base. If the existing boards show signs of rot or flex, we strip them back and lay down fresh OSB3 tongue-and-groove decking to give the GRP a completely rigid surface to adhere to.
The laying process needs a skilled hand and good timing. We roll out a liquid resin layer, bed in the heavy-duty fibreglass matting, coat it again to saturate the fibres, and let it cure. Once hardened, we coat the top with a dedicated grey finish that seals the whole system and stands up to UV rays. Purpose-fitted edge trims go around all fascias and drop-outs so water flows straight into your gutters without running behind the boards.
Fibreglass Roof Repairs in Barnet
GRP is tough enough that you can walk on it without causing damage, but severe impacts from heavy falling masonry or tree branches can sometimes craze or crack the surface.
If your fibreglass roof in Barnet takes a hit, you do not usually have to replace the whole deck. We grind back the damaged resin, dry out the timber underneath, key the surrounding surface, and laminate a fresh layer of mat and topcoat right over the break. When cured, it bonds directly to the old glass fibre and makes the roof fully watertight again.

FAQs
GRP is applied on site, allowing the laminate to follow many corners, upstands and changes in outline. More complex roofs require careful detailing and suitable trims, particularly where the covering meets walls or drainage points. The shape should be assessed before the deck and edge arrangement are finalised.
The deck provides the rigid base for the cured laminate. Boards need to be secure, level and installed so movement at joints is controlled. Poorly prepared decking can transmit stress to the surface above, so replacing damaged timber is only part of creating a dependable base.
Collected water can result from blocked outlets, debris or an inadequate fall in the deck. The cause should be identified rather than merely sweeping the water away. A GRP finish is designed to be watertight, but effective drainage still reduces unnecessary loading and helps keep outlets functioning.
Movement, impact and further weather exposure can enlarge an existing defect or allow moisture to reach the deck. Early inspection helps determine whether only the topcoat is marked or the reinforced laminate has fractured. Local repairs are generally simpler while the surrounding material remains sound.
The damaged area is prepared back to stable material, then compatible resin and reinforcement are laminated across it. Once cured, the patch receives a protective finish. Good preparation is essential because new material must bond to the existing surface rather than sit over dirt, loose coating or moisture.
Look over the surface for cracks, impact marks and lifting around edges, walls, outlets or rooflights. Clear debris using non-abrasive tools and make sure water can reach the gutter. A check after severe weather is worthwhile even when there is no obvious internal leak.
