SDH Advanced Developments LTD are fully certified to refurbish and install Sarnafil Single Ply Flat Roofs.
Sarnafil is the largest supplier of single ply roofing in the UK and is part of the global Sika Group Company, the largest single ply membrane supplier in the world.
Our systems have been independently certified to last in excess of 40 years.
We can replace old lead, copper patina and metal roofs with Sarnafil single ply which has no scrap value what so ever.
Lead and copper roofs are more vulnerable to theft than ever before. Schools and churches seem to be most at risk as they are often isolated and have a high level of lead and copper on their roofs. Sarnafil is much more effective than reinstating with milled lead or cooper roofing.
We provide a guarantee for 15 years, covering both the Sarnafil membrane and Sarnafil ancillary products used within the installation. We can also offer additional independent insurance backed guarantee with deposit cover and post-completion insolvency cover.
Quality Installation
Roof Assured Products are only supplied to Registered Installers to help you get the best possible roofing solution. Our staff were trained at Sarnafil's Training & Assessment centre, in Norwich, and each is issued with an identity card.
Aesthetically Pleasing
With a 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.
Environmentally Friendly
Our mmbrances are manufactuered in Switzerland to ISO14001, the international environmental production standard. This ensures that Sarnafil membrances have minimal impact on the environment. All our membrances are recyclable.
Value For Money
Our products have a life expectancy of 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.
