Fibreglass Roofing

A GRP flat roof, or fiberglass roof as it’s also known, is one of the most popular flat roofing solutions in the UK. GRP stands for Glass Reinforced Polyester, a composite material formed by strengthening plastic with fine fibres made of glass.

This single-ply laminate has been used as a reliable means of covering and waterproofing roofs for over 60 years. As well as commercial and domestic buildings, GRP has been used on a wide array of other applications, from boats and lorries to water tanks and ponds.

At Cumberland Roofing, we utilise the Cromar Pro GRP Roofing System which is highly regarded for its safety and robust finish. The finished product it produces is recognised as having a lifespan that easily betters that of a felt roof.

GRP flat roofs begin with a layer of catalysed resin being applied to good quality, completely dry roof decking, ideally OSB3 wood. A layer of fibreglass matting is then laid on top followed by another layer of catalysed resin to complete the system. Once cured, a fire retardant topcoat resin is then applied to completely weatherproof the roof and give it a more attractive finish.
