TPO is one of the most popular and readily available commercial roofing options and is fast becoming an excellent choice for homes with flat roofs. It’s a single-ply membrane that has a comparable price to PVC and EPDM. Despite this, it actually surpasses the two in utility and weather tolerance.
While popular, not a lot of people know what to look for in this single-ply roofing membrane. In this post, American Roofing Inc. discusses the features and aspects to take note of.
What Is TPO?
TPO, short for thermoplastic polyolefin, is a type of single-ply membrane roof introduced in the early 1990s as a more economical and efficient alternative to the then-popular PVC roof. One of its key features is its natural resistance to mold growth and dirt and its ease of resisting punctures and tears.
As with other membrane-based roofs, TPO uses common fillers such as talc, carbon fiber and fiberglass to reinforce it. All three of these are things to consider during the roof installation of your new TPO roof.
TPO membranes come in two thickness options: 45 mils or 60 mils, while the width and length of the membrane ultimate varies depending on the manufacturer. Thickness plays a key role in the weather resistance of the TPO roof, with the thicker membranes able to shrug off the negative effects of inclement weather very easily.
Commercial TPO roofs usually come in 80 mils due to the larger size of most commercial roofs, which, in turn, require more weather resistance.
TPO is an energy-efficient roof due to the natural solar reflectiveness of the roofing material. That said, the level of solar reflectiveness depends on the color of the membrane roof, with lighter colors boasting a higher solar resistance. Keep this in mind when you’re choosing a color for your new roof.
