Abstract : Because no procedures exist to inspect and evaluate the condition of single-ply membrane roofing systems within the ROOFER program, the U.S. Army Construction Engineering Research Laboratories (USACERL) has developed this inspection and distress manual for these roofing systems. Included is the standardized information needed to conduct the visual inspection survey, including names, descriptions, severity levels, measurement criteria, causes and photographs of membrane and flashing distresses. Procedures for distress density calculations are also provided. Roof inspectors can use this information to objectively determine the indexes that reflect the (1) ability of the membrane and flashing to perform their functions, (2) needed level of maintenance, and (3) waterproof integrity.
