With a number of different flat roofing systems out there, why should you choose Topseal GRP? The benefit with Topseal's GRP systems is that installers have the backing of a company that has 20+ years' experience in manufacturing high quality accredited flat roofing systems. We also provide an intensive training course at our head office in Harrogate for all our installers, as well as technical and specification support.

Installers have the reassurance that all our GRP roofing systems are BBA-certified and suitable for domestic and commercial work, both refurbishments and new builds.


Where installers are carrying out renovations of existing buildings, then a GRP system like Topseal Direct Lay has an advantage as it can be fitted onto existing substrates. This means that the roof refurbishment can be carried out more quickly and the building can remain in use throughout the process, providing greater convenience.

With health and safety being a priority, so are flat roofing methods that don't involve heat treatment. This is another reason why Direct Lay is popular as it is safe and easy to install, with no heat treatments required. GRP is also popular for its aesthetics as it is available in a range of colours and finishes to complement the aesthetics of a building.

As our flat roofing products can only be fitted by our approved installers, this gives Topseal installers a clear advantage.
