Heavy winds are especially bad on a roof when light asphalt shingles are used. Actual high wind resistance also involves the method of installation. In order to receive the most wind resistance on a roof, it is important that the entire assembly is geared toward this purpose. This begins with the structural deck and includes the insulation/board layers, the membrane and the surface covering. Flat roofs are often the best in this kind of situation as long as they are insulated properly with an EPDM or TPO membrane and there typically isn’t large amounts of precipitation to create ponding.
