EPDM is the most common single ply membrane roof material used in both residential and commercial works.
Being made of synthetic rubber or polymer, they are flexible and elastic which can handle temperature changes and some impact types far better than built up types of single ply options.
Developed in Europe in the 1960’s, this option is a single ply system made of asphalt bitumen, modified with polymers and reinforced with fibreglass and or polyester. Bitumen is heat, UV ray and tear resistant due to the reinforcement layers and can handle foot traffic well. One of the biggest drawbacks to this type of roof covering is that in general, the lifespan is typically between 10-20 years.
Torch-on roofing, or torch-down roofing as it is also known, is a flat roof covering solution that involves three layers of modified bitumen (felt) melt-welded onto the roof surface and each other with the use of a blowtorch to create an impenetrable, waterproof seal.
Traditionally, the three layers used in this process are a vapour control sheet, reinforced felt and a cap sheet with mineral finish. Using three layers of felt is required by building regulations for habitable areas of a home. For sheds and garages, only two layers may be needed.
Torch-on roofing felt’s reliability lay in its resistance to UV rays, strong winds and rain. The mineral finish of the felt breaks up sunlight as it hits it to stop the bitumen from melting. This means temperatures inside applications are kept cool during the summer.
Torch-on felt roofing can last anywhere between 15 and 25 years, depending on whether it’s a 2 or 3-layer system.
Liquid rubber is an instant set, fully bonded, rapid curing waterproofing system. Its unique formulation provides a highly flexible seamless finish that can be applied to ant existing surface be it an asbestos roof, concrete deck, existing roof, new build or vertical surface.
