High-Quality Fibreglass Roofing Supplies

FibreGlassDirect roof kits provide all fibreglass roofing supplies and materials needed to complete a flat roof build or repair. Fibreglass is widely regarded as a durable and robust material for flat roofing applications. When applied correctly, a fibreglass roof will easily last in excess of 20 years. 

We supply a comprehensive range of GRP Roofing Materials such as Trims, Kits, Resins and Topcoats which are specific for Fibreglass Roofing. 

Fibreglass is commonly used for Flat Roofs but can also be used for Pitched Roofing applications as well.

Fibreglass Roof Kits

Our complete Fibreglass Roof Kits are designed to make flat roof repairs affordable and easy to use for professionals and homeowners alike.

Each roofing kit is supplied with a high ratio of resin and topcoat to ensure your roof has enough coverage. 

For additional peace of mind, we offer a Fire Retardant Topcoat in our Premium Kits which has been certified to British Standards. The Fire Retardant Topcoat is also available to purchase individually. 

Our Roof Kits are designed depending on the amount of foot traffic that your roof is expected to take. 450g Matting is recommended for roofs that will have little to no foot traffic while roofs that will be expected to take moderate foot traffic would use one layer of 600g. If you are working on a balcony, we would recommed two layers of 450g Matting for extra reinforcement.
