Abstract
In recent years the use of elastomeric roofing systems in the United States has been increasing. A survey was conducted to ascertain the current state of the art of these roofign systems. The information obtained in the survey was gathered from a literature search complemented by the opinions of people knowledgeable in the field including researchers, contractors, manufacturers and users. A listing of the current elastomeric roofing membrane materials was compiled, along with test methods for determining the properties of membranes fabricated with these materials. The principal materials, available in either liquid or sheet applied systems, included acrylic, butyl, chloro- sulphonated polyethylene, EPDM, neoprene, PVC and vinyl, silicone and urethane. In addition, to these materials some composite membranes were also available. Factors affecting the performance of the membranes were identified including durability, design of the roofing system, substrate condition at the time of application attachment of the membrane to the substrate and workmanship during application. The performance of elastomeric roofing was discussed based on its advantages, disadvantages and limitations. Guidelines to assist the user in the selection and use of elastomeric roofing were prepared for both new and remedial roofing applications.
