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, although it's popularity has soared in recent 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.
The installation of a GRP roofing system is highly regarded for its simplicity and safety, while the finished product it produces is recognised as having a lifespan to compete with alternative solutions.
