Expert GRP Fibreglass Roofing in Sunbury-On-Thames
High class roofing provides professional GRP fibreglass roofing services for property owners across Sunbury-On-Thames and the surrounding 15-mile radius from our base in Datchet. Led by Jimmy Frankham, our team specialises in the installation of high-quality Glass Reinforced Polyester systems. We create seamless, waterproof membranes that are perfectly suited for flat-roofed extensions, dormers, and balconies common throughout the Spelthorne area.
Why Choose Us
Why choose GRP over traditional roofing materials?
Traditional multi-layer mineral felt often fails due to seams pulling apart, which leads to water ingress and pooling. Our GRP fibreglass systems are cold-applied, eliminating fire risks during the installation process and creating a single, joint-free surface. This material is exceptionally durable, resistant to UV degradation, and capable of withstanding light foot traffic, making it a superior, maintenance-free alternative for modern garages and rear kitchen extensions.
