Abstract

Facility managers and insurance carriers with extensive damages to roofs are concerned with the performance of sprayed-in-place elastomeric-coated SPF roof systems. This paper analyzes the resistance of different types of SPF roof systems. This research identifies: factors affecting the resistance of the SPF roof systems to hail damage; hail resistance characteristics of the SPF roofs near freezing temperatures; use of the `information theory' to modify and add decision-making information to the Factory Mutual Class I, Severe Hail (FM-SH) test; differences in hail resistance of SPF roofs and recommendations for expanding the FM-SH test.
