James Bros are pleased to offer GRP – Fibreglass Flat Roofing Systems.

What is a GRP / Fibreglass Roof?

A GRP / Fibreglass flat roof is a GRP laminate consisting of roofing resin and chopped strand reinforced matting applied in situ over a good quality OSB3 deck.The roof is finished with pre-formed GRP edge trims and a coat of pre-pigmented topcoat available in standard grey or any colour in the BS400 range.

Why choose GRP over traditional bitumous felt products?

Continuous testing of glass reinforced plastic ( GRP ) roofs have shown that we should expect the laminate to last 25 years plus compared to the ten years a felted roof will last, also as GRP-Fibreglass roofs are cold applied, the need to use dangerous tar pots and blow torches has been removed.
