Abstract
In recent years there have been reports of wind damage to fully supported aluminum standing seam roofs in the U.K. On investigation itwas found that the holding down clips made from aluminum had fractured at their base, allowing the roof panels to lift and eventually break away. This paper describes the findings from site investigations on two different roofs that failed at wind speeds significantly less than design. The mode of failure is examined, recognizing that the wind applies a cyclic dynamic load onto the lightweight flexible roofing system. This paper concludes with current best advice for designers and contractors.
