PJR Creative Building is proud to be one of few approved ProGRP installers in the UK.

ProGRP is a new advanced liquid applied GRP – Glass Reinforced Polyester – flat roof system. It has been specifically engineered for flat roof applications for the UK market. It is a fully integrated seamless system where all the components are designed to work together to ensure that you can take full advantage of this rapidly expanding market. ProGRP can be used on virtually all types of flat roofs up to an including vertical surfaces for example the cheeks of a dormer or the inside face of a mansard or parapet roof.

We have extensive experience using GRP to solve the problems often associated with the failed leaking bitumen felt roofs.

A ProGRP roof is a wet laid, singly ply GRP laminate made up of two layers of catalysed resin sandwiching a layer of chopped strand fibre mat (450/600gsm). It is applied to a new OSB T&G3 board. Profiled GRP edge trims are applied to the roof edged and abutments and the roof is finished with a coat of catalysed pigmented top coat.
