GRP Fibreglass Flat Roofs In Harpenden
Dormers are everywhere on Harpenden's Victorian, Edwardian and 1930s houses, and lots of them have small flat tops. Larger homes also have extension roofs that double as a place to step out. Glass-reinforced polyester, better known as GRP or fibreglass, is laid wet and cures hard under a topcoat, which makes it a good match for both.
Options for your roof
We install and repair across all major options to suit your home and budget.
Dark blue GRP on terrace
Seamless GRP fibreglass system with non-slip finish laid across a walk-on terrace.
Light grey GRP roof
Monolithic light grey GRP fibreglass flat roof installed with perimeter upstands and trims.
GRP garage roof
Ultra-durable GRP fibreglass coating applied to a residential flat garage roof.
Dormers, links and terraces in AL5
On a dormer, GRP can be moulded neatly up the cheeks and around the window frame without joints. For an extension that you want to walk on, perhaps to reach a window or clear leaves, the cured laminate stands up to foot traffic far better than older coverings. Each job begins with a dry, sound deck, typically new boards bonded and screwed down. We fit GRP trims, lay resin and glass matting, then add the coloured topcoat. The result is seamless and looks smart from upstairs windows.
Every job starts with a free survey and a written quote. Call 01727 649498 or book online.

Fibreglass cures best in dry, mild conditions, so we watch the forecast and will not lay it in rain. Under Harpenden's big trees, outlets and gutters need to stay clear afterwards. If your house is listed or in the conservation area, altering a visible dormer can need consent, which we check first. As a new roof, it comes with our 10-year guarantee.
