GRP Fibreglass Flat Roofs In Southminster
GRP fibreglass is a strong option for flat roofs in an exposed place like Southminster. Glass-reinforced polyester is laid wet over a new deck, then finished with a hard topcoat that cures into one seamless skin. There are no laps for the wind to lift, and the surface is good for walk-on areas, such as a roof you need to step onto for maintenance.
Options for your roof
We install and repair across all major options to suit your home and budget.

GRP on Southminster homes
Around the old centre, the post-war houses, bungalows and newer homes have plenty of flat-roofed garages, porches and outbuildings, plus some rear extensions. Many have failing felt or old repairs that have worn through. We remove the old covering, fit a new deck, and fix GRP trims to the edges. The resin and matting are then rolled out wet in one continuous layer, wrapped up into upstands, and sealed with the topcoat. Because GRP is formed in place, awkward shapes and outlets are dealt with neatly. If you want the roof to double as a walkway, we check the structure can take it. Our 10-year guarantee comes with every new GRP roof.
Every job starts with a free survey and a written quote. Call 01245 520306 or book online.

GRP needs dry, reasonably mild weather to cure, so we plan work around the forecast. In the conservation area covering the historic centre, we check whether a visible flat roof or terrace would need permission. Listed buildings always need checking first.
