A roof structure (10) 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 (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).
Structure (10) de toit et procédé permettant de réduire les forces de soulèvement sur un toit résultant du souffle du vent sur ledit toit à une vitesse élevée. Ledit toit possède une membrane (16) qui recouvre une plate-forme (12). Un matelas (24) souple et perméable à l'air est placé sur la membrane (16). Ledit matelas (24) possède des ouvertures dont la taille est destinée à réduire la vitesse du vent traversant ledit matelas pour atteindre la membrane (16) et dont la taille est telle que ledit matelas (24) n'est pas soulevé par un différentiel de pression à l'intérieur du matelas, ce qui réduit les forces de soulèvement agissant sur la membrane (16).
