What is a GRP Roof?A GRP roof is a single-ply GRP laminate applied in situ over a good quality conditioned plywood or OSB3 deck. The roof is finished with pre-formed GRP edge trims and a coat of pigmented topcoat. GRP has been used as a waterproofing material for over 50 years for applications as diverse as boats, water tanks, lorry and car bodies, roof lights, ponds and pools. When used to construct a boat, GRP will provide waterproofing for the boats entire lifespan without the need for maintainance or replacement. This same level of performance is easily replicated on a domestic roof.
