TPO (Thermoplastic Polyolefin) is a type of single-ply roofing membrane that’s quickly become a firm favorite for commercial properties. This relatively new roofing material has a fantastic range of benefits, being both cost-effective and energy-efficient, and it’s most commonly found on flat roofs. 

In this article, the roofing experts at A-to-Z Roofing & Exteriors are giving you the lowdown on TPO roofing. Here’s everything you need to know!

What is TPO Roofing? 

TPO is the acronym given to Thermoplastic Polyolefin, a synthetic material that’s used in roofing as a single-ply membrane providing an external cover to the structure of the roof. TPO is a unique blend of Polypropylene and Ethylene-propylene that has been deliberately developed for its distinctive advantages. 

TPO is incredibly versatile, but it’s most commonly used on flat roofs for commercial applications. You’ll often see distinctive, white roofs on large buildings in Colorado, reflecting the sunlight. These will undoubtedly be TPO roofs. 

TPO is part of a broader selection of rubber roofing materials, which include common materials such as PVC (Polyvinyl Chloride) and EPDM (Ethylene Propylene Diene Monomer). Since its widespread manufacture in the 1990s, TPO has become a distinct rival to these other popular roofing materials. 

Benefits of TPO Roofing

Enough talk of all these acronyms and synthetic compounds; what are the real-world benefits of installing a TPO roofing system on your property? 

TPO roofs have a range of benefits, including being low-cost, relatively easy to install, and remarkably eco-friendly. As a single-ply membrane, they also function as a resilient layer of protection for the roof structure, providing a weatherproof exterior. 

Let’s take a look at TPO’s best qualities in a little more detail.

Low Cost

One of the major benefits of TPO over similar materials is its relatively low cost. TPO can be manufactured in bulk as a synthetic material, and for that reason, manufacturing costs can be kept down. 

TPO is installed as a membrane over existing roofing structures, and the cost to actually install a TPO roof is cost-effective too. In addition, you can expect maintenance costs to be equally cost-effective, as well.


TPO is fantastically lightweight, making it a great choice for flat roofs. Not only does the light material make it easy to install, but it ensures that less reinforcement is needed beneath the membrane. 

TPO can be spread out over a large surface area with ease, making it a popular choice for large commercial properties. 


TPO is incredibly durable, too, a result of the unique synthetic compounds that have been blended together specifically to produce a material that’s perfect for roofing. 

TPO needs little maintenance and yet it can withstand the elements well, and in Colorado, that’s important. TPO is weatherproof and waterproof, and if it does need repairing, it’s low cost makes it easy to replace. 


TPO is most often installed as a bright white sheet, and for that reason, it works as an incredibly effective reflector. Bright white TPO will work to reflect the sun’s rays during the day, which in summer will stop your building from heating up inside. 

This ultimately stops energy wastage, as you no longer need to use as much energy to cool the building down when it’s hot outside. It stays naturally cool. This of course, also saves you money in the long run, proving TPO to be a worthy investment. 

Disadvantages of TPO Roofing

Of course, there’s no single roofing material that only comes with benefits. As roofing professionals, A-to-Z Roofing & Exteriors are happy to give you the disadvantages too when you’re deciding if TPO is right for you.

TPO is versatile and durable, but it is also a thin membrane. Yes, it’s lightweight and weatherproof, but other roofing materials are stronger. 

The second disadvantage comes from the material being fairly new. TPO is a modern, synthetic roofing material, and it has yet to prove its longevity (classic roofing materials, such as clay tiles, for instance, have been around for centuries, to give a comparison). There could be problems further down the line, but this is impossible to tell now. 

Overall though, we like to think that the benefits of installing a TPO roof, especially on a commercial property, outweigh the negatives. It’s cost-effective, highly resilient, and brilliantly energy efficient.
