Abstract
Until 20 years ago, almost all nonresidential roofing in the U.S. was either built up roofing or corrugated metal. New roofing materials and processes devleoped during World War II did not significantly affect the market. However, the Arab oil embargo in the 1970's drove up the price of bituminous roofing products, providing a new incentive to find alternate roofing materials. These new materials are now being used to replace damaged or failed low slope roofs. Most Air Force buildings have low slope, or built-up roof (BUR) systems. Although repairs are generally by in-house crews, roof replacement is usually completed by contractors because most Air Force bases no longer have the asphalt kettle equipment needed to install or resurface BURs. However, for some conditions other than economical, managers at Air Force bases should consider in-house installation of nonconventional systems as practical alternatives for low slope roof replacement. This report discusses the role of industry particpants, sources of roofing information, and the factors to evaluate when considering reroofing, and lists procedural steps for the roof engineer and roof technician.
