Fibreglass Roofs in Dublin

A Hard, Moulded Finish for Roofs with Awkward Shapes

GRP stands for glass reinforced plastic. Rather than arriving as a sheet, a fibreglass roof is made on the roof itself: resin is worked into glass matting laid over a timber deck, and it cures into a solid, continuous layer. A coloured topcoat then goes on to protect the laminate and give the surface its finish. The result is hard enough to walk on and has no laps.

We use Cure It GRP, and it comes into its own where a roof is anything but plain. Balconies, roofs with several upstands, valleys between two flat sections, or a dormer with a lot of edge detail can all be covered without the joins a sheet product would need. Preformed GRP trims give clean, crisp edges that suit modern extensions.

Fibreglass depends on dry conditions and a well-prepared base. We lay new OSB boards to the right fall, tape the board joints, and only start laminating when the weather allows, because damp boards and rain spoil the cure. Corners and upstands are reinforced with extra matting, and the topcoat goes on once the laminate has set.
