Roofing Materials

Asbestos was integrated into a wide variety of roofing materials until the mid-1980s. Asbestos was used in roofing products because it provided fire resistance, structural strength and flexibility, which are highly desirable traits for roofing applications. Shingles and siding commonly contained asbestos; however, asbestos was also widely incorporated into felt underlayments, sheathing, tars, simulated wood trim and cement corrugated board, otherwise known as transite. Asbestos was also used in cements, paints, mastics and putties, as well as other types of sealants used in roofing applications. CertainTeed, GAF, Bird, and Johns Manville were a few of the manufacturers whose roofing products contained asbestos.

Prior to the late 1970s, roofers, electricians, carpenters and other laborers were exposed to asbestos through the application, manipulation and removal of roofing materials. Unfortunately, exposure to asbestos can cause mesothelioma and other asbestos-related diseases. It was quite common for roofers or carpenters to cut or drill asbestos shingles and asbestos-cement corrugated board, also known by the Johns Manville trade name, Transite. This material was often utilized as a roof covering and building siding. Transite was typically manufactured in 4 foot by 8 foot sheets. Using a circular reciprocating saw, workers cut panels to a desired length. This process was extremely messy and created a lot of dust, which roofers and anyone in the vicinity inhaled.
