Single Ply Roofing by Sika-Trocal

~7522859Waterproofing typically accounts for only 3 – 5% of a project budget but its importance must not be undervalued. In fact, it is responsible for more than 25% of problems post-construction so should be considered at the earliest possible stage in the design and build process.

Decades of research and development have gone into the design and manufacture of liquid-applied waterproofing systems, so it’s vital to get the product and installation right. With smaller budgets and tighter deadlines than ever, as well as absolutely no room for error, the quality of specification has never been so important.

Whether obvious or unforeseen, roof problems are always a pain and undoubtedly a significant expense. Unfortunately, problems will be inevitable as a roof ages and deteriorates so it’s vital to choose a roofing membrane that will deliver long term performance with an application that is relatively simple, quick and hassle-free.

For many refurbishment projects, an adhered membrane should be considered where the existing surface is sound and remains firmly attached to the substrate. Additionally, as the membrane is exposed, any alterations are easily executed as access is easy and damage will be easy to spot and repair.

Mechanically fastened roofs are generally quick and economical to install and because of their lightweight nature, will often enable savings to be made on the supporting structure. Again, as the membrane is exposed, any alterations, fixes or repairs can be easily executed, as access is easy.

A ballasted (gravel/paved) roof will generally require a stronger supporting structure than that for the exposed membrane one, but will allow the roof to be used as a trafficked or leisure use area. Additionally, a ballasted roof will provide a higher degree of sound reduction and, if covered with minimum 50 mm depth of gravel ballast or 50 mm thick pavers, is deemed to achieve an FAA fire rating.

Once the single ply membrane and installation method has been specified, the relationship between the manufacturer and the roofing contractor will become absolutely crucial. So a supplier with an approved contractor scheme will ensure the roofing system is installed by a high quality and trusted applicator.

By utilising the expertise of the manufacturer and producing highly detailed plans before the project begins, you can get the job right first time, every time. Whatever the project, specifiers, contractors and their clients must turn to manufacturers and designers they can trust to ensure a quality specification that meets the very highest standards.
