Abstract
Although widely practiced within the roofing industry, roof re-cover, particularly over failed roofs that contain significant amounts of moisture, remains a controversial issue. The key issues surrounding this controversy are the drying of wetted insulation, deck deterioration (dry rot of wood, disintergratin of concrete, corrosion of metal) and fastener failuires. To address theseissues, a consortium made up of SPRI and its member companies, RCI, and ORNL have initiated demonstration projects to re-cover failed roofing systems containing moisture and to monitor the performance of those roofing systems after the reroofing.
