A seamless, walk-on fibreglass flat roof that lasts for decades, ideal for balconies and dormers across Amersham and Buckinghamshire. Free survey, fixed written quote, and a 15-year insurance-backed guarantee.
GRP, or glass-reinforced plastic, is the same tough material used in boat hulls, and it makes for an exceptionally durable flat roof. It is laid wet and cures into a single, seamless layer with no joins, overlaps or weak points, then finished with a hardwearing topcoat that locks out water for decades.
Because the finished surface is solid and walk-on, GRP is the ideal choice for balconies, terraces and dormers, as well as standard garage and extension roofs. We can add a non-slip finish to areas that get regular foot traffic. Fitted properly over sound, prepared decking, a GRP roof is a clean, low-maintenance solution that looks smart and performs for years.
One continuous layer means no overlaps and nothing to lift.
A solid surface that takes foot traffic for balconies and terraces.
The same tough resin used in boat hulls, built to take a beating.
A clean, neat topcoat in your choice of colour.
We inspect the deck and confirm GRP is the right fit for your roof.
A clear, fixed, itemised estimate with no obligation and no pressure.
We prepare the decking, lay the matting and resin, then apply the topcoat.
A final inspection with you, a tidy hand-over, and your 15-year guarantee.
