A commercial roof tends to have a low slope or is entirely flat and much larger than a typical residential roof. Flat roofs tend to require more maintenance and involve repairs of larger spaces that are installed in sections. When installed and maintained properly, the average commercial roof can last anywhere from 10 to 40 years. The life expectancy will vary, however, based on the materials used as well as a few other factors.
Thermoplastic Polyolefin (TPO) is a single-ply roofing membrane that is one of the fastest growing commercial roofing systems on the market. TPO roofing systems are made up of a single layer of synthetics and reinforcing scrim that can be used to cover flat roofs. TPO membranes are manufactured in sheets that are 10, 12 or 20 feet wide. These sheets are then rolled up and taken to the commercial facility. TPO has gained industry acceptance with the natural reflective surface to reflect UV rays. As reported by the National Roofing Contractors Association (NRCA) TPO takes up about 40% of the commercial roofing market share.
