GRP Fibreglass Flat Roofs In Harwich
GRP, or glass-reinforced polyester, is laid wet on site and cures into a hard, seamless shell. In a coastal town like Harwich that rigidity is useful: it shrugs off salt spray and gives you a surface you can actually stand on, whether it covers a rear extension or forms a small roof terrace.
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 fibreglass works best in Harwich
We tend to suggest GRP for the flat roofs on post-war houses that get foot traffic, such as a balcony off a bedroom or a roof you step onto to clean windows. Fibreglass also suits awkward shapes, because it is moulded rather than cut from a roll. The process is simple to follow: a new deck goes down, resin and glass matting are laid and rolled out, and a coloured topcoat seals the surface. Edge trims are bonded in, so the whole roof becomes one solid piece with no joins to open up.
Every job starts with a free survey and a written quote. Call 01206 648098 or book online.

Resin needs dry weather to cure, so on this exposed peninsula we plan the laying around the forecast and cover the deck if a shower blows in. A new balcony or terrace can need planning permission, especially inside the Old Town conservation area, so we check that before you commit.
