Abstract
Severe (golf ball sized) and oversized (baseball to softball size) hail has caused millions of dollars of damage to roofing sytems. Facility managers and insurance carriers with extensive damages to their roofs are concerned with the performance of sprayed-in-place elastomeric coated SPF roof systems. Results of this research incude: 1) analysis and identification of performance factors of different types of elastomeric coated SPF systems for their severe and oversized hail resistance capability. 2) Identification of the hail resistance of SPF systems under normal and freezing temperatues. 3) Use of documented performance information to cofirm hail resistance levels determined by static testing. 4) Identification of the validity of current industry information on hail resistance of elastomeric coated SPF roof systems. 5) Proposal for an industry process to reduce the risk of hail damage to SPF roof ystems.
