A monolithic, seamless shell
GRP (glass-reinforced plastic) fibreglass is the toughest flat roofing system available. Resin is applied over glass fibre matting to form a single, seamless, monolithic shell that is completely watertight and impact resistant. Unlike felt, it has no seams to fail and, unlike rubber, it can take regular foot traffic — making it ideal for balconies, walk-on roofs, and flat surfaces that see heavy use.
We lay OSB3 decking, bond the fibreglass resin and matting in one continuous pour, then finish with a coloured non-slip topcoat. The result is a single, jointless surface with no weak points — water simply cannot find a way through. Available in charcoal and slate grey finishes, GRP is the premium choice for any flat roof that needs to perform for the long term.
