Patent attributes
The present invention relates to a method of securing multiple layers of roofing material onto a building with need for ballasting objects. A plurality of roofing panels are installed across a roof deck forming a first layer. Then a plurality of fasteners are installed in each roofing panel of the first layer of roofing panels. Each fastener comprises a base having opposing longitudinal surfaces and a fastening member secured to and extending away from each opposing longitudinal surface. An adhesive is then applied to a surface of either the first layer or a second layer of roofing panels. The plurality of fasteners then perforate the surface of each roofing panel of the second layer to secure the second layer to the first layer, thereby allowing the adhesive to cure, preventing wind from resetting the panels, and without external ballasts.
