Currently, commercial roof contractors hand weld a roofing membrane with edge metal strips while standing at the edge of the roof at a job site to create a metal drip edge. For example, to achieve a commercial workmanship warranty, the contractor is required, at roof perimeters, to terminate the roof with ANSI/SPRI/FM 4435/ES-1 compliant details. (Sec, e.g., ES-1, “Wind Test Design Standard for Edge Systems Used with Low Slope Roofing Systems,” which is a standard addressing wind resistances testing of edge metal systems, except gutters, used to secure the perimeters of low-slope membrane roof systems.) Basically, the roofing membrane is required to wrap over the roof edge with an edge metal fastened over the top. This detail requires the edge metal to then be stripped in to waterproof the metal and fasteners. This can be done in a few different ways. One method is to use an adhered cover strip. Another method is to use TPO clad metal (on TPO systems) or PVC clad metal (for PVC systems) and heat weld a flashing strip to the metal and membrane. A few manufacturers allow the field membrane to be welded to the top of the clad metal, which is not ES-1 compliant. In that case, the roof perimeter is secured by only the bottom half of the membrane, which is not securing the reinforcing scrim layer. Thus, to achieve the ES-1 compliant details requires a considerable amount of labor by the installer, while working at the edge of the roof. This is tedious, slow, and dangerous. Accordingly, the current methods of creating a metal drip edge result in high inefficiency in labor cost, safety, and case of installation.
For example,
As further shown in
Thus, the purpose of the current invention is to offer a simple, easy to use, pre-fabricated product that will improve safety, labor cost, and case of installation in a significant way. In this regard, a new pre-fabricated product is proposed that provides a pre-welded or secured TPO/PVC membrane to edge metal that will offer labor savings, faster installation, and safety. Thus, the proposed pre-fabricated product will address the current methods of hand welding single-ply TPO or PVC membranes with edge metal at the job site, which results in unsafe conditions for the installers, high labor cost, and low productivity.
