UV radiation and building movement can cause cracks, splits and blisters in a traditional felt roof. Failure can also result from poor design or installation.  Sarnafil single ply membranes are flexible, installed by trained Registered Installers and certified, by the British Board of Agrément, to last in excess of 40 years.

Sarnafil provide a guarantee for 10 or 15 years covering both the Sarnafil membrane and Sarnafil ancillary products used within the installation. In addition the independent insurance backed guarantee will provide you with deposit cover and post completion insolvency cover for 10 years.

Sarnafil Roof Assured products are only supplied to Registered Installers to help you get the best possible roofing solution.  Sarnafil Roof Assured Installers are trained at Sarnafil’s Training & Assessment centre in Norwich and each trained fitter is issued with an identity card carrying their photograph, qualification level and expiry date.

With Sarnafil’s range of colours, aesthetic profiles and complementary edge trims we can provide a solution that is sympathetic to your property. We can simulate a traditional lead or copper appearance, and we can also help you benefit from a roof terrace or garden roof.

Sarnafil membranes are manufactured in Switzerland to ISO14001, the international environmental production standard.  This ensures that Sarnafil membranes have minimal impact on the environment. All membranes are recyclable and each new m2 contains a percentage of recycled membrane.

Sarnafil products have a life expectancy in excess of 40 years, require virtually no maintenance and are installed by trained experts. We can even improve the thermal efficiency of your home with high performance thermal insulation. Combined, these elements provide you with the best possible value for money.

Only by undertaking an investigation of the roof build up and condition, can problems be identified
and recommendations be made for remedial action.

Correct preparation is critical to the provision of a long-term solution that solves your roofing problems.

Installed without naked flames, hot bitumen, multiple layers, or resins, the Sarnafil membrane is simply secured to the roof using the most appropriate method.

Sarnafil roofing membranes are permanently fused together by hot air welding joints and details.
This ensures a durable and watertight finish.

Aesthetically pleasing membrane coated edge trims are available in a choice of colours. These provide strong weather resistant roof edges.
