TPO Flat Roof is a single-ply style flat roof system that has many of the same benefits of the more expensive PVC flat roofing system, but cheaper. Though TPO Flat Roofs are costlier, they are more energy efficient, very durable and easy to install.


TPO is a single-ply membrane made of thermoplastic polyolefin rubber. TPO roofing is often likened to a combination of PVC and EPDM because it offers many of the benefits of the two systems and few drawbacks. TPO is seen popularity in the residential and commercial market since its creation in the 1990’s.



Technically there are three layers to TPO:


One of the main selling points of TPO roofing is that it’s cheaper than PVC roofing, but still offers the same benefits like weldable seams and better energy efficiency than EPDM. TPO resists mold, dirt, tears and cuts very well. It is a very flexible yet durable material that handles natural building movements (think expansions because of temperature) very well.

TPO has a number of innate properties that make it energy efficient, heat resistant and fire resistant, making it a good choice if you want to keep your utility bill down. It is impossible to go over all the benefits of TPO on this page so here is an abridged list:

Any member of AM Flat Roofing & Sheet Metal will be more than happy to discuss with you any of these benefits and more.


While the pros definitely outweigh the cons we believe you should be well informed before making any decision as big as this one. Like we mentioned earlier, TPO is a fairly new roofing material in comparison to some of the other options. As such the life expectancy on the roofs is uncertain. We can say that based on current statistics, well maintained TPO flat roofs last 10-30 years, but as you can see, that’s about as long as TPO roofs have been around to begin with. As TPO technology advances it’s guaranteed this life span will increase, but it’s hard to conclusively say by how much. Also, because TPO is new, there is a constant tweaking on the chemical formulas. While this means you will get the newest and most advanced membrane available, you may find there are several advancements that come out soon after you get your TPO roof installed.

AM Flat Roofing & Sheet Metal’s TPO Installation

TPO flat roofs are one of the easier roofing systems to install. Sheets come in a wide variety of sizes and can be mechanically attached or fully adhered using a couple different methods. Hot air welded seams provide the strongest bond possible and make the seams 3-4 times stronger than EPDM seams. Getting a TPO flat roof installed by us can be done in as little as a day depending on your current roof and roof size. We always start by properly inspecting your current roof so we can give you an accurate estimate and troubleshoot any problems before the installation day.
