FIX-R FLEXI-GRP Roofing Kits

The new FIX-R FLEXI-GRP Roofing Kits include all the components you will need in order to successfully install a GRP roof. There are ten different kits to choose from with varying sizes, coverage rates and application types.


FIX-R FLEXI-GRP is the evolution of standard GRP by giving a seamless, flexible finish that won’t crack or peel. In addition to new OSB3 roofs, FIX-R FLEXI-GRP can be applied to existing stripped decks (if in suitable condition). It can also be used as an overlay on a variety of substrates such as Single Ply, GRP, Concrete, Asphalt and Bitumen.


Smooth kits are suitable for use on GRP, new Single Ply, worn Felt, smooth Concrete/ Screed and OSB3 TG4.


Medium kits are suitable for use on Mineral Felt, medium-finish Concrete, medium-finish Asphalt, OSB3 TG4, uneven GRP and uneven Single Ply.


Rough kits are suitable for use on old Concrete/ Screed, rough Asphalt and Cementitious Panels.
