GRP Fibreglass Flat Roofs In Grays
GRP suits Grays homes where a flat roof gets used, not just looked at. If a rear extension below a bedroom window doubles as a small terrace, or a porch roof has to take a ladder for window cleaning, fibreglass gives a hard, seamless surface that copes with foot traffic far better than felt.

Fibreglass roofs on Grays homes
Across Grays, many extensions added to 1930s to 1970s houses were finished in felt that has since cracked and pooled. When the owner wants something tougher, we lay GRP. We fit a new board deck, then lay glass-reinforced polyester wet over it, soaking a fibreglass mat in resin so it cures into one rigid layer. A coloured topcoat goes on last for weather and sunlight protection, and preformed GRP trims form the edges and drips. On the Victorian terraces near the town centre, it also works well on small back-addition roofs that need a tidy, hard-wearing finish.

GRP has to be laid in dry weather and sensible temperatures, so in a damp Thames-side spell we may move the date rather than rush the cure. If you plan to use the roof as a balcony, that can need planning permission even when re-roofing alone would not. A new GRP roof is backed by our 10-year guarantee.
