Company info

Smartseal Flat Roofing Ltd was established in 2005, by Darren John, who has 22 years experience in GRP and liquid roofing systems. Smartseal specializes in GRP and rubber/liquid systems, which includes 25-30 year guarantees. Our roofs can have an added optional independent insurance backing, if required.

Smartseal systems offer an alternative to traditional forms of roofing which have proven to be superior to the traditional bitumen based waterproofing systems. Our systems are designed to provide complete waterproof protection for 100-years, or more. Furthermore, they are designed to deliver a low carbon footprint installation solution, which is environmentally safe, and energy-efficient.

It is designed with the ability to conform to practically any shape and size of building construction, and can further be applied with a wide range of colours from the Topseal 98 BS4800 range. The roof can be completed in 3 finishes, which include: smooth, aggregate, or non-slip. We also cover a range of styles to suit standard specification from a standard flat roof, to complete water containment. 

Smartseal roofs are all fire retardant and completely UV resistant. They suitable for use on historic buildings, and new build, for retrofitting or for any architecturally challenging building project. 

While the GRP roofing system boasts qualities that arguably make it the best roofing system money can buy. These qualities are dependent on how the roof is laid. GRP can be rendered completely ineffective if it is laid incorrectly. The performance of the roof is therefore reliant on the contractor's ability to lay it.
