Abstract

A method includes obtaining a roofing membrane. A first layer of the roofing membrane is applied along a length of a roofing substrate covering a first portion of the roofing substrate. At least a first edge of the first layer is fastened to the roofing substrate. A second layer of the roofing membrane is applied over the first layer along the length of the roofing substrate such that a first edge of the second layer overlies the second edge of the first layer. The first edge of the second layer and the second edge of the first layer are fastened to the roofing substrate using a second fastener in a fastening zone along the length the roofing substrate. The second layer is reoriented such that the second layer overlies the fastening zone and covers a second portion of the roofing substrate adjacent the first portion of the roofing substrate.
