Claim Text:
1. A ballast free method for improving single ply roof performance in wind conditions on a roof having a substantially flat deck with turbulent wind vortex areas and a field-of-roof area outside the turbulent wind vortex areas, said turbulent wind vortex areas having a higher wind load than the field-of-roof area, comprising: determining the turbulent wind vortex areas of the substantially flat deck, gluing and mechanically fastening an under layer of insulation to the substantially flat deck in the turbulent wind vortex areas and field-of-roof area, gluing and mechanically fastening a single ply roofing membrane to the under layer of insulation in the turbulent wind vortex areas, said single ply roofing membrane having a row of mechanical fasteners along a first edge at a roof edge and a row of mechanical fasteners along a second edge; loose laying the single ply roofing membrane over the entirety of the under layer of insulation in the field-of-roof area, said single ply roofing membrane in the turbulent wind vortex areas having a row of mechanical fasteners on a transition between the turbulent wind vortex areas and the field-of-roof area; and, installing at least one vent only in the field-of-roof area outside of the turbulent wind vortex areas.
