GRP Fibreglass Flat Roofs In Letchworth Garden City
Arts and Crafts houses in Letchworth often have dormers with small flat tops, and later homes have extensions and balconies that people want to step out onto. GRP fibreglass suits these well. It is laid wet, sets into a hard seamless layer and is finished with a coloured topcoat, giving a surface you can walk on.
Options for your roof
We install and repair across all major options to suit your home and budget.

Where fibreglass earns its place in Letchworth
Small dormer roofs on the older cottages are fiddly to cover, and the way GRP can be moulded around upstands and corners makes it a neat fit. On flat-roofed extensions from the post-war estates, homeowners sometimes want a roof they can reach for clearing leaves or maintaining a window, and fibreglass handles light foot traffic well. The job starts with a sound, dry deck, often new boards where the old ones have gone soft. We fit edge trims, lay the resin and glass matting, then apply the topcoat once the laminate has cured.
Every job starts with a free survey and a written quote. Call 01438 870485 or book online.

GRP needs dry weather to cure properly, so we plan around rain rather than rushing. On homes under the Scheme of Management, altering a dormer's shape or finish may need consent, and we check before quoting. A like-for-like re-cover is usually simpler. New flat roofs come with our 10-year guarantee.
