Hurricane Performance of Spray Polyurethane Foam Roofing

The 2004 hurricane season in Florida provided a unique opportunity to observe the performance of SPF roofing systems following actual high wind events. The four hurricanes which came ashore that year demonstrated that SPF roofs performed very well. Most SPF roofs survived with undamaged or with minor surface damage and building occupants remained protected by the roof system. Some roofing failures were noted, however, due, in part, to the failure of the structural roof deck or the substrate.
