About Topseal

Topseal offer a range of advanced GRP fibreglass roofing systems fitted through a national network of highly trained and approved installers.

Since our flat roof system was introduced back in 1992 it has been installed on millions of square metres of roofs all over the UK.

Topseal is the ultimate fibreglass flat roofing system suitable for both domestic and commercial works.

We continue to innovate and have recently launched a ground breaking direct lay flat roof system. This liquid applied flat roofing system has secured BBA certification and is suitable for refurbishments and new builds.
