EPDM , a type of synthetic rubber, is an elastomer used in roofing systems. Roof assembly consists of structural base element, like fibrous deck as the substrate layer that is fully adhered to top layer EPDM membrane that covers the system and prevents damage and water intrusion. The focus of research was to study the nature and threshold of damage caused by hailstone impact on fully adhered EPDM used in roofing systems. Hail impact experiments were conducted on EPDM of various thicknesses using a hailgun, projecting ice balls at hailstone terminal velocities. Irrecoverable damage to the roofing structure was defined by loss of adhesion between EPDM and the underlying substructure, which makes EPDM susceptible to tearing failure as a result of cyclic wind load. In addition, dynamic Finite Element Analysis (FEA) of hail impact on EPDM were performed using LSDYNA finite element for comparison with the experimental results.
