Why Choose Us

Why GRP Fibreglass is Ideal for Local Flat Roofs

Gerrards Cross features a diverse mix of architectural styles, from modern residential extensions to post-war semi-detached properties. GRP roofing is particularly effective here because it is a cold-applied system, which eliminates the fire risks associated with torch-on bitumen alternatives. The resulting membrane is exceptionally strong, resistant to UV degradation, and can easily withstand light foot traffic. By choosing a fibreglass system, you are investing in a low-maintenance, long-term solution that prevents common flat roof issues like seam splitting and water pooling.

Is GRP Fibreglass the Right Choice for Your Extension?

Many property owners ask if GRP is suitable for their specific roof structure. Fibreglass is an excellent choice for most residential flat roofs, particularly those with complex detailing such as upstands, roof lights, or narrow drainage channels. Because the material is applied as a liquid and cures into a solid, seamless sheet, it avoids the vulnerable joints that cause traditional felt roofs to leak over time. If your existing flat roof is showing signs of blistering, sagging, or interior staining, a new GRP installation may be the most cost-effective way to secure your home.
