What You Must Know About GRP Fibreglass Roofing
What is GRP Fibreglass Roofing?
GRP or glass reinforced polyester is a single-ply laminate material made of plastic strengthened with fine, glass fibres.
Although the material has been in existence for over sixty years, its popularity has increased in recent times, possibly because the Cromar range of resins and sealants have made installing a GRP roof accessible to the non-professional roofer.
GRP roofs are very modern, light and versatile enough for use in contemporary and traditional structures. Today, you can see GRP roofs covering a variety of buildings, and used in the making of boats and water tanks.

A GRP roof is a wooden deck, made from OSB-3 sterling board usualy tongue and groove 2ft by 8ft boards. pictured right…
free of structural faults. The GRP roofing professional places layers of catalysing resin and fibreglass upon one another, and then leaves the layers to cure or dry, a process that takes ten or fifteen minutes. a top-coat layer is then added with OR without non-slip finish If you are a handy roofer, you can install a GRP roof quite easily. However, edge trims and drip trims – often custom made – must be added to the roof before the layering process can begin. For this reason, it makes sense to hire a professional company, such as Abbey Roofing Cumbria, to carry out installation.
The Advantages of grp roof covering
Although the GRP roof is costlier to install than a felt or EDPM rubber roof, its long life – up to 25 years guarantee – means a cost saving for the customer in the longer term. Since the wooden deck is cut to fit and the resinous material is liquid moulded around details such as skylights, installation is relatively easy. Normally, the material is resistant to UV light, but the colour can fade over time. If this happens, you simply restore the lost shade by adding another top coat. The GRP material is generally impact resistant but if the roof does develop a crack or a hole, you can carry out a repair by adding one or more layers of resin and fibreglass roof top coat finish.
