NRCA and the Midwest Roofing Contractors Association (MRCA) have revised their guidelines for safely torch applying polymer-modified bitumen sheet products. Specifically, the changes affect safety practice recommendations for applying polymer-modified bitumen membrane flashings over combustible substrates.

The changes are reflected in the current Certified Roofing Torch Applicator (CERTA) program, which provides training in the latest safety practices and industry requirements for torching activities through the combined use of manuals, video instruction and a hands-on training class. It is the only program of its kind available in the roofing industry.

The program's curriculum was developed in 1986 through joint efforts of MRCA; the Asphalt Roofing Manufacturers Association; and United Union of Roofers, Waterproofers and Allied Workers. In 2003, the insurance industry approached NRCA to address concerns about increasing incidents and losses occurring during torching activities by roofing workers. NRCA arranged with MRCA to adopt and revise the CERTA program to meet this industry need.
