Expert GRP Fibreglass Roofing in London and Westminster

GRP roofing has rapidly become the preferred choice for homeowners and commercial clients alike. By moving away from traditional bitumen-based materials, you unlock a host of long-term benefits that protect your property and enhance its kerb appeal.Completely Waterproof and Seamless: Because GRP is formed as a single continuous layer, there are no joints or seams where water ingress can typically occur, guaranteeing leak-free roofing.Exceptional Durability: Fibreglass is tough enough to withstand heavy foot traffic, making it the ideal surface for roof terraces, balconies, and green roof installations.Maintenance-Free Finish: Unlike felt that can blister or crack in the sun, our UV-resistant topcoat ensures your new flat roof retains its integrity and colour without ongoing upkeep.Weather Resistant: Engineered to handle extremes of temperature and heavy rainfall, a GRP roof is built for the demanding British climate.

What is the difference between GRP and EPDM?While both are excellent flat roof replacements, GRP (Glass Reinforced Plastic) provides a hard, rigid surface that is ideal for balconies or areas needing regular access. EPDM rubber roofing is highly flexible and slightly quicker to install, making it great for standard extensions. We can advise on the best option for your specific property during our roof survey.How long will a GRP fibreglass roof last?When installed correctly by experienced roofing contractors, a GRP flat roof can easily last upwards of 25 to 30 years. Because the materials are completely seamless and highly resistant to weathering, they require virtually no maintenance.Can you install GRP over my existing felt roof?No, GRP must be laid onto a completely dry, clean, and structurally sound timber deck, specifically OSB3 boards. Applying it directly over old, potentially damp felt will trap moisture and cause the new fibreglass to fail. We always conduct a full structural assessment and install a fresh deck to guarantee longevity.
