What Is TPO Roofing?

What Is TPO Roofing?A TPO roofing system is a good choice if you have a flat roof or a low-sloped roof. It is energy efficient and long-lasting. TPO roofing systems have all the advantages of EPDM and PVC roofing systems, but without the added cost. TPO roofing systems can be heat-welded just like PVC roofing and are as UV and heat resistant as EPDM roofing. TPO roofs have some drawbacks, as with all roofing systems. They were introduced to the market in the early 1990s. Market research continues and the flaws in the roofing system are still being sorted out.

What is a TPO Roofing System and how does it work?

TPO stands for Thermoplastic Polefin. TPO roofing systems were introduced to the market in 1990 as an economical and more efficient roofing system than EPDM and PVC. TPO is a single-ply thermoplastic polyolefin membrane made up of three layers. These layers include the TPO polymer base and polyester reinforced fabric center, also known as scrim, and the thermoplastic polyolefin compounded topped ply.

The most commonly used fillers in the TPO manufacturing process are fiberglass, talc, and carbon fiber, as well as metal oxy, sulfurate, and wollastonite. EPDM and ethylene-propylene rubber are the most commonly used rubbers in TPO manufacturing.

What are the benefits of a TPO Roof


TPO roofs are cheaper than other roof systems like PVC. TPO roofing systems have the same benefits of more expensive roofing systems, such as being heat-weldable and efficient, but at a lower cost. TPO roofing systems are versatile and can be fitted to many roof types and slopes. TPO roofs are available in a variety of colors, including black, light grey, or light grey. They also remain energy efficient. A TPO roof is more energy-efficient than a white roof.


This roofing system can withstand the effects of dirt, mold, and debris. TPO roofs are very flexible and can be adjusted as the building or home settles. TPO roofs are more resilient to thermal expansion and contraction of buildings than single-ply roofing systems.

Easy Installation

TPO roofing systems are easy to install. This roofing is lightweight and available in large rolls. This makes it easy to move and requires less welding. The customer benefits from the ease of installation.

Energy Efficiency

Many customers find TPO roofs attractive because they are more energy efficient and have a lower carbon footprint. TPO’s white reflective surface surpasses the EPA energy star requirements. The white, tan, and grey surfaces are all listed with the Cool Roof Rating Council. A TPO roof may be the right roof for you if you want to cool your home and reduce your energy costs.

What are the drawbacks of a TPO roofing?


These roofing systems were only introduced in 2005. There is still much research to be done to determine the best chemical formula for TPO roofing. Many manufacturers have had to overcome this challenge. There have been cases of membrane cracking or curling, seam failure and membranes bursting. Although newer membranes and formulas have been tried, it is not yet possible to predict how long they will last. It is best to choose materials from a company that has been in business for a while when installing a TPO roofing.

Questionable Heat Load

Some TPO membranes can experience accelerated weathering under higher temperatures than usual. These problems have been particularly noted in southern states, where the roof is constantly exposed to heat and sunlight. Consider the possibility that temperatures can regularly exceed 160 degrees.

There is a high risk of solar loads exceedingly “normal”. It is recommended that you ask the manufacturer for information about their product durability in such situations.
