Arguably, the most innovative design enhancement in roofing systems was the introduction of the single-ply roofing membranes. Successful in Europe for many years, the systems were first introduced in the United States in the 1970’s. Over the past thirty years, a number of different membranes have been successfully introduced including EPDM, Hypalon, CPE, PVC to name a few. These membranes have performed well but, as with all building materials, will require maintenance at some point in the life of the system. Many of these membranes, installed in the later 70’s and 80’s are now out of warranty. Several have developed problems such as UV attacking the surface causing chalking, crazing and cracking. Seams and flashings have weakened and become loose causing water infiltration. What options does a building owner have? Since the single-ply systems are relatively new compared to conventional built-up and metal roofing systems, the restoration solution has only been recently addressed. Do you proceed with expensive tear-off and replacement? Can a new membrane be installed over the existing one? What about weight load? Cost of new installation? Conditions of existing insulation and deck?

A possible alternative solution is to apply a coating system designed to protect the existing membrane and extend its service life. Not just any roof coating can be applied to weathered single-plies. Uniflex has developed a unique coating system designed to be applied to provide excellent adhesion to Uniflex approved membranes. Once installed, the coating provides a seamless, self-flashing, bright white finish that protects against damaging UV rays, reduces energy costs and eliminates costly membrane replacement. Uniflex offers a free, comprehensive roof inspection to determine if the single-ply membrane is in condition to warrant the application of the coating system. Condition of the membrane and underlying substrate is critical to consideration for coating.
