Methods of Single Ply Roofing Application

Methods of Application

With today’s construction trends of highly intricate and complex structures and the requirement for higher thermal insulation values, only single ply roofing membranes which aspire to the highest quality standards and possess unquestionable technical properties, will be considered in the design process. The versatility of Sureplan FPO ensures the designer total freedom and security when specifying the roof waterproofing system.

Mechanically Fastened System

Mechanically fixed single ply roof systems are often favoured above timber or metal decks where the exposure of the fastener on the underside of the structure is not a consideration. This method of application involves the use of thermally broken fasteners fixed at pre-determined centres and is a fast and cost effective method of installing the single ply membrane which is less dependent upon amicable weather conditions.

Fully Adhered System

Fully adhered single ply roofing systems are more commonly used above concrete substrates where the process of installing mechanical fixings is invasive and labour intensive. Fully adhered systems are reliant upon suitable weather conditions (which should be considered) however, complex geometries and pitched surfaces can be accommodated with great success. Fully adhered membranes can also provide a superior surface finish.

Ballasted Roof System

In ballasted systems the waterproofing membrane is loose-laid and welded together at the overlaps prior to the application of a ballast which holds the membrane in place. This method offers maximum restraint to wind uplift and fast application times, while providing protection from mechanical and solar/UV damage.

The single ply roofing membrane can be placed above the insulation in a warm ballasted roof buildup.

Alternatively, the membrane may be used in an inverted warm roof situation, where the insulation is placed above the waterproofing. These inverted ballasted systems also provide maximum resistance against membrane damage, UV degradation, thermal shock, fire and noise.

Ballasted roof systems offer an excellent solution for situations where access or recreation is a priority.
