In January, NRCA and the Midwest Roofing Contractors Association (MRCA) issued a report about a fire-testing research program they conducted. The research revealed some findings that should be of concern to roofing professionals.
In 1996, MRCA undertook a limited series of fire tests intended to determine the fire resistance of "aged" roof membrane systems. Half the specimens tested passed the tests, and the other half failed.
In 2001, MRCA conducted an additional series of fire tests on aged roof membrane systems. Again, only half the specimens passed the fire tests.
