A strong and waterproof flat roofing solution will keep you warm and dry

Customers often make a decision about a new flat roof based on costs and aesthetics but when it comes to a flat roof cheapest is definitely not always the best. Performance and longevity should be at the top of the list – the last thing any homeowner wants to do is  renew a flat roof after a few years or have a roof that suffers from leaks and other problems.

Drainage and maintenance are always main concerns when it comes to a flat roof. Traditionally, flat roofs have had a reputation for being difficult to weatherproof but products such as the Sarnafil single ply membrane guarantees longer lifespans, weatherproofing and durability.

Ideally all flat roofs should have a low (slight) fall to allow rainwater to drain from the roof.  Part L Building regulations states a minimum fall of 1:80.  However, particularly in refurbishment projects, this isn’t always achievable.  Rest assured, the Sarnafil single ply flat roofing membrane, heat welded at every seam and either mechanically or adhered (designed in accordance with BS6399:Part 2) to the underlying surface, will cope with standing / ponding water without detriment to the product or the guarantees.

Also steel reinforced details and a unique seal copes with building movement and guarantees a waterproof wall joint, that will not crack or fail.  Sarnametal steel reinforced edge trims are mechanically fixed to form a solid, storm resistant roof edge.  The Sarnafil waterproofing is fusion welded to the Sarnafil trim to permanently seal the roof edge.

And as far as durability goes the Sarnafil waterproofing membrane has been independently assessed by the British Board of Agrement (BBA) to last in excess of 40 years, in their opinion.

As we say – the Sarnafil single ply flat roof membrane protects homes around the world whatever the weather throws at it!
