Single ply roofs for any shape of building

Strong, flexible synthetic membranes that suit flat, curved and unusual roofs. Fitted by our own approved team.

Overview

Single ply membranes are made from synthetic polymers, so they are strong, flexible and light. They can be shaped around awkward details, which makes them a good answer for unusually shaped roofs, including curved barrel roofs.

We are approved installers for Sarnafil (Sika), Danosa, Alwitra and Soprema Flagon. Each has its strengths, and we will recommend the one that suits your roof, your budget and how you plan to use the space.

Whether you are refurbishing an original roof, building an extension or roofing a block of flats, we can help. A correctly specified single ply build-up can also help eliminate condensation problems.

Which single ply membrane will you use?

Our roofing systems carry a 15 or 20 year guarantee, and in most cases an insurance-backed manufacturer warranty is available. We will confirm the exact cover in your quote.
