1. Exceptional lifespan

SOPREMAs SBS bitumen membranes have a tested life expectancy of over 30 years. With a multi-layer bituminous roofing membrane system, a reliable and robust waterproofing solution can optimise longevity for the building. Bitumen roofing requires little upkeep over the years, although annual maintenance is recommended to extend its lifespan.

2. Versatility and sustainability

Bituminous roofing membranes are not just for flat roofs, but can also be applied to barrel and dome roofs, ballasted and complex profile roofs, and guarantees a seamless finish for upstands and complex detailing. Bituminous membranes are also available for green roof applications. Root resistant bituminous roofing membranes, such as SOPRALENE Flam Garden 250 AF, can be used for green roofs as they stop the roots from penetrating the waterproofing system.

3. Ideal for refurbishment projects

Bituminous roofing membranes are perfectly suited to refurbishment projects where existing bituminous or asphalt systems have exceeded the performance lifespan of the existing waterproofing system.
