Single-ply membranes are installed over flat or low slope roof systems. It is a safer and longer lasting alternative to the older torch down or modified bitumen roof systems of years past. Of all the single-ply membranes on the market PVC has been the one to have the best and most proven track record. It has far outperformed TPO and EPDM membranes. Our list of PVC products we have installed

Most single-ply systems are installed by two methods, Fully Adhered and Mechanically Fastened. A fully adhered installation is using a glue or an adhesive to attach the PVC or TPO to the decking, with the overlapping seams welded with a heat gun. A mechanically fastened system is installed by using screws and plates to attach the PVC to the roof deck, also with the overlapping seams welded with a heat gun or walk welder. In most cases a mechanically fastened roof is the safest and most common method of installation. A roof that has a concrete deck or wants to eliminate any wrinkles or billowing of material will opt for a fully adhered application. These same methods apply to TPO applications as well. We are certified installers of GenFlex (division of Firestone) for all commercial applications and NDL warranties.
