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 pre-pigmented topcoat.


The durability and lightweight properties of GRP make it the ideal construction material for roofs and gutters.  GRP is also used in hostile industrial settings for applications such as tanks and underground pipes; this is due to its ability to withstand high temperatures and its resistance to chemicals. Unlike other roofing materials it is robust, flexible and will never corrode.
