Topseal GRP flat roof system installed by Right Roof Solutions

When installing a glass reinforced plastic (GRP) fibreglass roof, we use the Topseal GRP Flat Roof System. This is the leading system in the market and widely recognised in the building industry and often specified by architects.

This system can be used on a variety of domestic and commercial roofing projects, including new builds, garage roofs and refurbishment projects.

Topseal is also suitable for cold and warm roofs. The versatility of this system ensures that it will fit in with almost any style from ultra-modern homes to more traditional listed buildings.

In addition, Topseal’s fibreglass flat roofing system has a life span that will outlast traditional bitumen based roofing systems.

One of the most fundamental features of a fibreglass flat roof, setting it apart from other options, is that it’s a monolithic laminate. Many traditional roofs are bitumen based which requires tar boilers. But GRP is a cold applied system, which means the laminate is formed without the risks associated with using naked flames or burners on a roof.

This means that it does not suffer any weakness at seams, joints or welds, which are usually the weak points within a flat roof. GRP is made of one continuous layer and can mould on or around almost anything.
