Abstract
The EPDM Roofing Association retained the services of Jim D. Koontz & Associates, to perform laboratory testing on 81 test targets provided by the association. The targets varied in age and substrate. The samples were impacted with ice spheres ranging in size from 1 to 3 inches utilizing National Bureau of Standards Procedure 23. Impact points were analyzed for relative damage. This presentation will be offered at an advanced level and will provide detailed technical data based on the results of the tests. These tests will confirm the results of previous anecdotal studies that have shown the EPDM has an outstanding performance record against hail damage and will also show that these results continue throughout the life of the membrane.
