Abstract
The roofing industry has had a consistent share of the U.S. construction industry output the last three years with the total production hovering around the $17 billion level. As the construction industry shifts toward "retrofitting" existing facilities, the reroofing market has grown. Problems have arisen, caused by the added insulation to retrofit jobs, the proliferation of roofing products, the lack of entry and exit barriers, the lack of understanding of roof system performance, the shrinking maintenance budgets, the rapidly changing composition of roof systems and the "low bid" award systems of the procurement of roofs. Richard Boone, director of RIEI, states that there is a "...perception that (BUR) roof life has declined from 20 years to seven years." Unreinforced PVC and EPDM roofs have had similar problems. Polyurethane roofs have had their share of premature replacments. Understandably, liability for nonperformance is a concern for roofing industry participants and facility owners.
