Flat Roofing Specialists

Quality Service UK Wide


In 2020, Derwent Roofing Services Ltd was the UK’s largest Sarnafil contractor in terms of square meterage – over 40,000m2 of Sarnafil fitted. Nevertheless, we remain a family business, passionate about quality and good service; we aim to build long-term relationships with our customers by providing a competitive, flexible and efficient service.

We are happy to quote for Sarnafil work anywhere in the UK – we currently have contracts in London, Cambridge, Cumbria, Birmingham, Leamington Spa and Nottingham. Although we use Sarnafil single-ply membranes exclusively, we can also quote for associated works such as roof-lights, small amounts of tiling, rain-water goods etc.

We look forward to working with you in the future.
