Why Choose Us

Why choose GRP over traditional flat roofing materials?

Many older flat roofs in Chertsey and Runnymede suffer from ponding water or splitting seams, often due to the limitations of aging mineral felt. GRP fibreglass is a superior, cold-applied alternative that forms a single, joint-free layer across the entire roof deck. Because it is applied as a liquid and cures into a solid, reinforced shell, it eliminates the vulnerable seams that typically lead to leaks. This material is not only UV-resistant but also incredibly durable, making it an excellent choice for surfaces that require occasional light foot traffic.
