We now install well over 20,000m2 of Sarnafil annually. Nevertheless, we remain a family based 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.
Since March 2007 Derwent Roofing Services Ltd has been on the Sarnafil Plus Register. Approximately only 10% of all Sarnafil registered contractors are accepted onto the this Register, approved to act in a “Main Contractor” capacity on refurbishment projects. Each of the companies has signed the Plus Charter, providing the client with a single point responsibility guarantee, covering design, materials and workmanship.
We are happy to quote for Sarnafil work anywhere in the UK. 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.
