Membrane Roof Lifespan

The specifier or client can draw some comfort on how long their single ply roof should last from the membranes independent testing such as a bba certificate.

Membrane roof lifespan.

Sbs roof membrane modified bitumen. The rubber that comprises this roof s membrane is what puts it at a higher lifespan of anywhere from 20 to 30 years. According to righteous rubber roofing epdm roofing membrane has an extremely long lifespan and is able to stand up against years of inclement weather thermal cycling and extreme uv exposure. It can also stay flexible at hot or cold temperatures.
