GRP Fibreglass Flat Roofs In Borehamwood
GRP fibreglass is a strong option for Borehamwood's many flat roofs, especially on extensions that need to look smart or get walked on. Post-war homes across the town have flat-roofed garages and back extensions, and where those original felt roofs have failed, GRP gives a hard, seamless replacement.
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.

Where GRP fits in Borehamwood
We often fit GRP on rear extensions with a door or window opening onto them, and on garage roofs that owners need to step onto for maintenance. On many estates, the original felt has split along the joints and the boards beneath are spongy. Our GRP roofs start with a new timber deck. Resin is then laid wet into a layer of glass-fibre matting, which cures into a single, bonded laminate. A topcoat goes over it for colour and protection, and GRP trims form the edges, drip and upstands. The finish is clean and suits newer homes on the edges of town as well as post-war houses.

Because GRP must cure in dry conditions, we schedule it carefully in wetter months. Joined garage roofs need a neat junction with next door. Roof terraces and balconies may need planning permission, so check with us before planning a sitting-out area. Our 10-year guarantee covers the new flat roof.
