What is fibreglass (GRP) roofing?
Fibreglass roofing—also known as Glass Reinforced Plastic or GRP—is a modern, high-performance roofing system. It combines glass fibres with a resin coating to create a strong, seamless and fully waterproof surface.
Unlike traditional felt or tar roofs, which can degrade over time, a GRP roof forms a tough, flexible shell that resists water ingress, UV damage and extreme weather. The result is a low-maintenance, long-lasting flat roof with a clean, attractive finish.
Benefits of choosing fibreglass roofing
-
Long-lasting protection – GRP roofs are highly durable and designed to last for decades with minimal upkeep.
-
Fully waterproof and weather-resistant – Excellent performance against rain, wind and UV exposure.
-
Seamless finish – Reduces the risk of leaks compared to tiled or felted systems.
-
Low maintenance – No need for regular treatments or frequent repairs.
-
Versatile application – Suitable for most flat roofs, including extensions, garages, porches and commercial properties.
-
Custom guttering – Box and valley gutters can be formed in GRP, avoiding the expansion issues associated with lead.
-
Choice of colours – Select a finish that complements your property.
-
20-year guarantee – Added peace of mind on all our fibreglass roofing projects.
Replacing old felt or tar roofs
If your current flat roof is made from felt or tar and is starting to show its age—lifting, cracking, pooling water or leaking—fibreglass is an excellent upgrade.
GRP roofing provides a stronger, more reliable and longer-lasting alternative to traditional materials. Our team can remove your old roof and install a new fibreglass system with minimal disruption to your home or business.
