    Desirable performance characteristics common to all roof installations are the ability to accommodate movement and to remain functional at ambient temperatures while resisting the extremes of the elements, particularly the ravages of ultraviolet light, air pollutants, and water. Synthetic rubbers possess desirable performance attributes for single-ply roofing membranes, particularly those sheets based on properly formulated compositions of polychloroprene, chlorosulfonated polyethylene and ethylene/propylene/diene terpolymer. The latter elastomers have demonstrated long-term resistance to weather and water in a variety of other applications to a degree that has commended their consideration as sheet rubber roofing membranes throughout the world. Such membranes have satisfactorily served as integral parts of successfully functioning roofing systems for 15 to 20 years.

    The fundamental characteristics of these synthetic rubbers as single-ply rubber roofing membranes are examined by reviewing: (1) architectural and design considerations, (2) installation parameters, (3) performance and durability, (4) synthetic rubber polymers, (5) role of rubber products manufacturer and contractor/installer, and (6) industry acceptance.
