  • Structure and method of reducing and redistributing uplift forces on membrane roofs
    Patent number: 5784846
    Abstract: A roof structure and method for reducing uplift on a roof resulting from a wind blowing over the roof at a rooftop wind speed. The roof has a membrane overlying a deck. An air permeable and resilient mat is installed over the membrane. The mat has openings of a size to reduce the wind velocity passing through it to the membrane while the openings being of a size that the mat is not lifted by a pressure differential therein reducing uplift on the membrane.
    Type: Grant
