Why Choose Us

Why Choose GRP Fibreglass for Your Flat Roof

Flat roofs on many Ashford properties often suffer from water pooling and joint failure, especially when older multi-layer felt systems begin to degrade. Our cold-applied GRP fibreglass installation eliminates the fire risks associated with torch-on bitumen. Because the system is applied as a liquid resin with glass matting, it moulds perfectly to complex roof shapes, upstands, and abutments, creating a single, unbroken waterproof seal that is highly resistant to UV rays and extreme weather.

Who We Are

Meeting Building Regulations and Thermal Standards

When replacing a flat roof covering, we strictly adhere to Building Regulations Part L requirements regarding thermal performance. If the roof deck is being significantly renewed, we ensure that modern insulation boards are incorporated to meet current U-value standards. This not only keeps your home warmer and more energy-efficient but also protects your roof structure from the risks of interstitial condensation.

Does my flat roof in Ashford need a full replacement

Determining whether a roof requires a full replacement or a targeted repair depends on the condition of the underlying timber deck and the extent of any water ingress. Our team conducts thorough surveys to assess the structural integrity of your roof. In many cases, if the decking is sound, we can provide a robust GRP upgrade that offers peace of mind for years to come. For properties with active leaks, we can provide temporary weatherproofing while we plan the permanent installation.
