GRP Fibreglass Flat Roofs In Royston
GRP fibreglass suits Royston homes that need a flat roof to be tough as well as tidy. It is laid wet as polyester resin and glass matting, then sealed with a topcoat that cures into a hard, seamless surface. With no laps to lift in the wind off the surrounding hills, it is a strong choice for extensions, garages and dormers.
Options for your roof
We install and repair across all major options to suit your home and budget.

GRP roofs on Royston homes
We fit GRP on post-war and newer homes across Royston, especially on extensions overlooked by upstairs windows and garages that people use for access. The old covering comes off, the joists are checked, and a new deck goes down. We then lay the resin and matting as one continuous layer, wrapping it into preformed edge trims and up the wall at the abutment. The topcoat goes on last. Because the whole roof is formed from one material, there are no seams for wind or water to work at, and the surface takes light foot traffic in its stride.
Every job starts with a free survey and a written quote. Call 01438 870485 or book online.

GRP needs dry, mild weather to cure properly, so we plan work around the forecast and protect the roof if showers arrive. In the historic centre's conservation area or on listed homes, visible changes may need approval. We check this before quoting and explain what it means.
