TPO (thermoplastic polyolefin) Roofing
Green Apple Roofing is proud to offer TPO Roofing Systems. Over the past decade, TPO membranes have succeeded in gaining strong roofing industry credibility based on their physical property characteristics, wide sheet technology and long-term rooftop performance throughout the world. We strictly adhere to all ASTM TPO specifications, helping to ensure product quality, durability and longevity.
TPO roofing membranes are currently the fastest growing segment of the U.S. single-ply roofing industry. Green Apple Roofing uses TPO roofing membranes on polypropylene and EP (ethylene-propylene) rubber polymerized together using state-of-the-art polymer manufacturing technology. This technology enables the TPO membranes to be flexible at low temperatures without the use of polymeric or liquid plasticizers. Unlike some other popular thermoplastic roofing membranes, the TPO polymer does not contain chlorine and no chlorine-containing ingredients are added during sheet production. The result is a roofing material that is both environmentally friendly and extremely durable.
Another important characteristic of TPO membrane is its high level of reflectivity. Because of this, white TPO membranes can meet and even substantially exceed the U.S. Environmental Protection Agency’s ENERGY STAR performance levels. Those ENERGY STAR marks that have been posted on refrigerators, water heaters and other appliances for years now can be seen on rolls of white TPO membrane. White TPO membranes typically display reflectivity ratings in the high 80 percent range when new (ENERGY STAR specifications require 65 percent minimum) and in the low 80 percent range after three-year rooftop exposure with cleaning (ENERGY STAR specifications require 50 percent minimum). TPO membranes are highly resistant to mold and algae growth, which can degrade the overall reflectivity of the roof and reduce anticipated energy savings.
