Abstract
This paper reviews current wind design guidelines for aggregate ballasted single-ply membrane roof systems and discusses selected case histories from Hurricane Hugo. It addresses the importance of careful design of ballasted roof systems to avoid aggregate blow-off during high winds, which may result in personal injury or property damage. Additionally, the paper notes that designers need to have adequate design guidelines to develop suitable wind-resistant systems. Finally, the paper presents conclusions and recommendations for enhancing performance of aggregate ballasted single-ply membrane systems and provides recommendations for improvements to the primary U.S. wind design guidelines.
