West Roofing Systems, Inc. uses multiple brands of Single-ply membranes, with a variety of different types within each manufacturer, which allows us to meet the needs of each customer for single ply roof OH. Each type of Single-ply membrane is designed to deliver a high quality of performance and durability, depending on weather conditions within each region.
Ethylene Propylene Diene Monomer, a Single-ply membrane consisting of a synthetic rubber compound allows it to remain flexible. EPDM is predominantly used in a 45, 60, or 90 mils thickness and offered in either black or white. For our Northern region, a dark EPDM is used in order to retain optimum sunlight and help reduce energy costs. In the Southern region, where it is warmer, a white EPDM or “Cool Roof” is used to help reflect sunlight and keep the structure cooler. Installation of this membrane usually comes either fully adhered or mechanically fastened.
Thermoplastic Polyolefin, a Single-ply membrane consisting of a synthetic rubber compound reinforced with fibers and a polyester scrim. Unlike EPDM, TPO is hot-welded and fused together at the seams. TPO is predominantly used in a 45, 60, or 80 mils thickness and offered in white, tan or gray. Typically white is chosen, which helps reflects direct sunlight and helps reduce cooling energy costs. Installation of this membrane usually comes fully adhered or mechanically fastened.
