On every installation, Fibreglass, Glass-Fibre, or GRP is a hard, plastic-like material that is installed immediately on top of a new roofing deck. It is wet placed in place, resulting in a fully bonded and seamless structure. There are no failure points, no laps, and it is incredibly durable. You can slam a hammer on our fibreglass roofs as hard as you want; there will be no damage. This is why our loyal customers return for every new roof they require and always recommend the GRP system to anybody they tell about their beautiful new roof.
