The EPDM membrane is essentially one piece of rubber, cut to size for
your job. The membrane can survive all forms of weathering and will
last 50 years or more. Its so strong its been tested to withstand desert
and arctic temperatures.
Since the rubber is glued straight onto the roof surface it easily
and quickly creates a water tight seal for your roof. So no need for
any flames or heat treatment, it’s also incredibly flexible meaning
that it wont rip or crack.
