Pros and Cons of TPO Roofing
Since its introduction in the 1990s, TPO roofing has continued to grow in popularity compared similar materials. TPO is now one of the most popular flat roofing solutions available, and for good reason. It offers property owners a flat roofing solution that is affordable and durable. But, to determine it it’s the right flat roofing solution for you, you need to weigh the pros and cons of TPO roofing.
TPO is short for thermoplastic polyolefin, a blend of rubber, ethylene and propylene bonded with a variety fillers, including talc and fiberglass. This blend of materials makes TPO one of the strongest available solutions for flat roofing and a formidable choice against everything mother nature has to offer. Though TPO is single-ply, it is one of the thickest plys available, making it a good choice especially for commercial properties with roofs that are subject to heavy foot traffic, reducing maintenance needs. TPO is also resistant to mold growth and dirt accumulation. It is made to be flexible, which helps it account for foot traffic as well as building movement or thermal expansion. The average lifespan of a TPO roof is 15-20 years.
TPO roofing is available in rolls. These rolls are offered in three different widths, so you can more easily customize the cut and sizing for your roof. With multiple sizes, your contractor is able to provide you with a better, more custom fit: a roofing system that matches to the exact shape of your roof. This also helps reduce the number of seams, which reduces the opportunity for moisture to enter your roof’s underlayer and cause leaks. TPO roofing also comes in a variety of colors, such as white, light gray and black.
TPO roofing offers the same benefits of heat-welded seams (such as with PVC roofing) at a more affordable price point. At a price point comparable to EPDM roofing, TPO provides benefits comparable to PVC roofing, a more expensive flat roofing option. TPO is also easy to install, and a quicker, easier installation means savings for the property owner.
Another added benefit of TPO that it is eco-friendly. Because TPO roofing materials are 100% recyclable, installing a TPO roof can reduce roofing waste. TPO is also free of chlorine, which can be toxic to the environment. TPO roofing is also energy efficient, especially in reflective, light color options such as white, tan and light gray. These colors reflects the sun’s rays instead of absorbing them, such as a dark- or black-colored roof would. The absorption of this UV light converts to heat, which is then transferred into your property, causing it to be warmer and require more energy to cool down.
Con: Not as established
TPO is still a relatively new roofing material. Though this means that more research and knowledge of other, more established roofing materials has gone into the creation of TPO roofing, there is still an element of experimentation uncertainty regarding installation and lifespan. Though new and improved formulas and methods are constantly being discovered, there is still risk involved. To minimize this, be sure to enlist an experienced, licensed contractor who knows the ins and outs of TPO roofing.
Con: Can’t handle excessive heat
TPO roofs that are exposed to high amounts of heat and sun can experience accelerated weathering. This is particularly a problem in southern states that experience a lot of direct heat and sunlight year-round and not so much in states with more temperate and variable weather.
