GRP Flat Roofing

GRP or Fibreglass roofing is one of the best, reliable ways to weatherproof flat, pitched or barrel-vaulted roofs.

Its low-maintenance and quality materials make it one of the most cost-effective roofing methods available.

What does a GRP flat roof involve?

Materials required to fibreglass a flat roof include;

Fibreglass roofing consists of wetting out layers of glass mat on the roof of the building. When cured, your roof should have strength and provide a continuous waterproof barrier across the surface of the roof. One layer of 450g glass mat is standard for a roof with no footfall, 600g glass mat should be used in areas of light footfall and 900g or two layers of 450g for balconies or areas of heavy footfall.

When the resin has cured, the Roofing Topcoat can be applied. This not only adds colour to the roof but also acts as a tack-free sealant to secure the fibreglass underneath. If there is a requirement for the roof to be walked on after the build, we recommend that a non-slip topcoat is used. To achieve fire resistance topcoat should be applied at a rate of 0.8kg/m2.

Once cured, the roof will be seamless and waterproof. It will also be virtually maintenance free. Unlike other roofing materials, the fibreglass will not rot or smell and is less likely to gather organic moss. If needed, the roof can be easily cleaned with a mop or hose or simply brushed.

Advantages of a GRP Flat Roof

Fibreglass Roofing offers many benefits including;

  • Safer Installations: GRP Roofing requires no complicated machinery and in most cases does not require heat equipment resulting in safer installations and reduced risk of on-site accidents
  • Durability and Strength: Most fibreglass roofs have a life expectancy of 20 years once they have been installed correctly
  • Flexibility: Choose from a variety of trims to suit the roof build. Materials can also be easily cut to suit the shape of the roof
  • Waterproof: Has no seams
  • Resistant to weathering: Waterproof Topcoat finish
  • Easy to repair and maintain: Brush or hose the completed roof to keep it clean

GRP Roofing Applications

Fibreglass Roofing is suitable for both domestic and commercial use. In commercial applications it is used for schools, hospitals and office blocks.

For domestic purposes it can be used for extensions, sheds, garages, porches and balconies (with non-slip topcoat) to name but a few.
