ABSTRACT:
A roof system which includes a generally moisture and gas impervious membrane connected to the roof structure at its perimeter. A suction device driven by the wind or electrical motors or a combination of both creates a suction between the membrane and the roof substrate which causes the membrane to be held closely to the roof substrate. The wind driven suction devices increase the suction between the membrane and roof substrate in direct proportion to the velocity of the wind crossing the roof area.
