Fibreglass Roofing Rochester | Durable GRP Roofs

The Problem

Why Fibreglass is the Premium Flat Roof Choice

If you want the strongest, most durable flat roofing system available, GRP fibreglass is the answer. Unlike felt or rubber, fibreglass creates a completely rigid, seamless shell over your roof - there are no joints, no seams, and no weak points. It's the same material used in boat hulls, which tells you everything about its waterproofing credentials. For homeowners who want a flat roof they can forget about for decades, fibreglass is the premium choice.

Our Solution

GRP Fibreglass - Built to Last

Our GRP (Glass Reinforced Polyester) fibreglass roofing system creates a single, seamless, incredibly strong surface over your entire flat roof. The system is built up in layers - resin, fibreglass matting, and a topcoat - to create a rigid, waterproof shell. Available in a range of colours including grey, green, and black, with optional anti-slip finishes for walkable areas. We offer guarantees of up to 25 years on our fibreglass installations.
