Roof Assured by Sarnafil offers self builders and renovators a fit and forget flat roofing system from Sika Sarnafil, the world’s largest manufacturer of single ply membranes.

In the past few years there has been a huge rise in the number of flat or low pitched roofs on self build and renovation projects. This is partly a design trend towards modern styling but also the increasing cost effectiveness of this roofing option. As a result single ply membranes are proving to be a real game-changer for people building new or low pitched flat roofs. Easy and quick to fit they are also cheaper than metals such as zinc and lead, are high performance and pleasing on the eye.

Sarnafil know that for many homebuilders and renovators a self build project is the fulfilment of a lifelong ambition and a painstaking journey towards creating an individual, unique home of their own. That is why the quality, performance and aesthetics of the roof are so important. The Sarnafil single ply membrane has a long history of developing and delivering high quality products, which is why, for many architects ‘Sarnafil’ has become a generic label for single ply membranes.

The high performance Sarnafil membrane is strong and flexible and can either by mechanically fixed or fully adhered to the roof surface. All Roof Assured by Sarnafil products come with a 15 year guarantee and are expected to last in excess of 40 years (independently assessed by the British Board of Agrément (BBA), in their opinion). This is based on actual projects that were installed in the demanding environment of Switzerland (home to the Sika Group) in the early 1960’s and still performing well to this day.

When it comes to roof covering Sarnafil know that quality products are only as good as their installation. All Roof Assured by Sarnafil projects are managed by Trained Registered Installers who have great insight and experience in fitting the Sarnafil membranes. They are used to working with homeowners, designers, surveyors, architects, project managers, building control, heritage and many more.  If extra help is needed on a project then they are supported by our expert team of Field Technicians.
