To guarantee an expected lifespan of 25 to 30 years, a GRP roof must be installed with meticulous attention to detail. Our specialists never cut corners. We begin by entirely stripping away the old, failing substrate, whether that is torn felt or cracked asphalt, right down to the joists if necessary. We then install brand-new OSB3 tongue-and-groove decking to create a structurally sound, perfectly flat base.Next, we fit specialised edge trims, such as D-trims and B-trims, to direct water flow into your guttering efficiently. The core installation involves applying a precise ratio of liquid resin and glass fibre matting, which cures to form a solid, impenetrable laminate layer. Finally, we finish the surface with a pigmented, UV-stable topcoat. Because the chemical bond requires specific conditions, we strictly monitor the local weather, ensuring we only lay the system on a dry deck in temperatures above 5°C.
