STRUCTURE AND METHOD OF REDUCING UPLIFT OF AND SCOURING ON MEMBRANE ROOFS

摘要

A roof structure (10) and method for reducing uplift on a roof resulting fro m a wind blowing over the roof at a rooftop wind speed. The roof has a membrane (16) overlying a deck (12). An air permeable and resilient mat (24) is installed over the membrane (16). The mat (24) has openings of a size to reduce the wind velocity passing through it to the membrane (16) while the openings being of a size that the mat (24) is not lifted by a pressure differential therein reducing uplift on the membrane (16).
