GRP (fibreglass) roofing has a number of benefits compared to traditional roofing products, especially for flat roofing. Unlike traditional flat roofing systems, GRP flat roofs are extremely durable and completely waterproof, plus they can be finished in any wide range of colours and include options such as nonslip finishes. The entire area on a GRP roof is encapsulated into one single continuous GRP membrane and there are no seams joints or welds. It is also completely UV resistant.

GRP roofing systems are also highly adaptable allowing conversion of the roof area to include features such as balconies or walkways within the roof area. Special features such as roof lights can also be included. GRP roofing systems can also be used instead of pitched roofs or to make special features. The major benefit of GRP roofing comes from the fact that a high-quality GRP roofing system installed correctly should remain leak-free for at least 50 years.
