TPO (thermoplastic polyolefin), is a single-ply roofing membrane that has been used in both residential and commercial roofing for the last three or more decades. There are a wide range of reasons why TPO is an excellent choice for roofing, so let’s take a look at some of them.

Initial Cost Savings

One of the big reasons people choose TPO roofing for their home or building is because it tends to be quite cost effective. TPO offers a lot of the same benefits as PVC roofing, including hot-air weldable seams and energy efficiency, but at a lower cost to you. There are some factors to be considered when you are estimating the cost, such as labor charges, the thickness of the TPO, the method that is used to attach the TPO, and the time of year (Spring and Summer may cost more since they are busier seasons). But even considering these factors, TPO does tend to cost less than the competing products. The current average is estimated between $5-$10 per square foot.

Ongoing Cost Savings – Energy Efficient Roofs

Energy efficient roofs save money and TPO roofing is very energy efficient. One of the reasons is because the reflective surface helps lower the amount of energy needed to cool down a building by repelling the heat of the sun. TPO is UV resistant, as well. For the best energy efficiency performance, you want to purchase a TPO membrane with a smooth surface. A smooth surface offers the most protection against dirt and debris, which can severely reduce the roof’s reflective properties and lead to accelerated aging.


Another advantage of TPO roofing is its durability. The flexible nature of the membrane makes it very resistant to tears, punctures and damage from impact of any kind. This flexibility also allows for a building to move and settle, without compromising the roof’s performance. Reinforced TPO also handles thermal expansion and contraction more effectively than the other single-ply products out there.

Ease of Installation

One of the last benefits worth mentioning is the ease of installation of TPO. The sheets are wide and lightweight, so there aren’t as many seams, which means they are easier to install. Keep in mind that when it takes less time and labor to install this roofing, you will save on installation costs. These single-ply membranes can be installed in several different ways. They can be point-affixed, mechanically attached or fully adhered.
