GRP Fibreglass Flat Roofs In Manningtree
If you want a flat roof you can walk on, GRP is hard to beat. Glass-reinforced polyester is laid wet, built up with glass matting and finished with a topcoat, curing into one solid layer. For Manningtree homes with extensions or flat dormers, it gives a tidy, hard-wearing surface with no seams.

We install and repair across all major options to suit your home and budget.

Fibreglass roofs on Manningtree homes
Around Manningtree, Mistley and Lawford, we use GRP mostly on rear extensions, flat dormers and the odd balcony or roof terrace on newer homes. It's especially useful where people need to step onto the roof, for instance to clean windows or maintain a neighbouring slope. To lay it, we remove the old covering, fit a new deck and add preformed trims around the edges. Then the resin and glass mat are rolled on in one continuous coat, with corners and upstands formed in the same layer. Once cured, the topcoat goes on, giving a smooth finish in a colour of your choice.

Being close to the Stour estuary means damp air, so a flat roof here must shed water quickly. We set the falls carefully and make sure outlets and gutters take water away cleanly. GRP is laid in dry weather only. New fibreglass flat roofs come with our 10-year guarantee.
