GRP Fibreglass Flat Roofs In Chelmsford
GRP fibreglass suits Chelmsford homes where a flat roof needs to take a bit of foot traffic or has awkward corners to deal with. It is laid wet, layer by layer, onto a new deck and sealed with a hard-wearing topcoat, so it cures into one seamless surface that is happy to be walked on.
Options for your roof
We install and repair across all major options to suit your home and budget.

Where fibreglass makes sense in Chelmsford
Newer homes in Springfield, Beaulieu Park and Channels often have flat-roofed extensions under bedroom windows, and owners want a surface they can step onto to clean glass or reach a gutter. On older streets in Great Baddow, Broomfield and Melbourne, the job is usually replacing tired felt on a garage or rear addition. In both cases we start with a sound deck, lay glass matting saturated in resin, form the edges with GRP trims, and apply the coloured topcoat once the laminate has cured.
Every job starts with a free survey and a written quote. Call 01245 520306 or book online.

GRP needs dry weather to lay and cure properly, which helps in a city in one of the driest corners of the UK, though we still watch the forecast closely. If the roof runs up to a neighbour's, we talk about the party wall edge before we start. Like any new roof we fit, it carries our 10-year guarantee.
