What Is TPO Roofing?
Thermoplastic polyolefin, also known as TPO, is a durable rubber roofing membrane known for its exceptional performance. This membrane is made by heat-fusing a TPO polymer base, a polyester fabric or material in the middle, and a TPO polymer top ply.
White TPO membranes are the most popular option and can help maintain the temperature of commercial buildings by reflecting harsh sunlight instead of absorbing the heat.
TPO roofs have pros and cons, which we will share in this article.
What Are The Pros Of TPO Roofs?

TPO roofs are made by blending polypropylene and ethylene-propylene rubber, making them a durable flat roofing material. Because of this, TPO roofing systems have grown to dominate about 40% of the commercial roofing market.
One of the main advantages is the white surface of a TPO roof membrane naturally reflects sunlight and UV rays, which substantially reduces the load on your building’s HVAC system.
The material costs are generally lower than many alternative commercial roofing systems, and the installation process is more straightforward, which helps keep labor costs in check.
Durability is another most impressive thing about TPO roofing systems. Modern TPO roofing membranes are engineered to resist tears, punctures, and impact damage, making them suitable for commercial applications where roof traffic is common.
Additionally, the material maintains its integrity even under harsh weather conditions, and with proper maintenance, a TPO roof can last between 20 to 25 years.
What Are The Challenges With TPO Roofing Membranes?
While TPO roofing systems have various advantages, it’s important to understand their potential limitations.
The quality of TPO products can vary significantly between manufacturers, which makes choosing a reputable brand is very important. Some lower-quality TPO materials may not perform as well over time, potentially leading to premature aging or deterioration.
The performance and the integrity of the seams also need to be checked regularly after installation. Although the TPO membrane itself is highly durable, the seams between sheets can become vulnerable points if not properly welded.
This is why choosing experienced installers who understand the specific requirements of TPO roofs is crucial for a long-lasting system.
How Much Does It Cost To Install A TPO Roof?
Understanding the cost of a TPO roof installation helps property owners make decisions about their roofing system.
The exact cost of installing TPO roofs on your property depends on a few things, but here we will share general estimates so you know what to expect when installing TPO roofs.
For a 20,000-square-foot commercial roof, you can expect to spend between $4 to $16 per square foot, depending on specific project requirements. Larger commercial projects mostly see lower per-square-foot costs, averaging around $12.
These costs encompass more than just the TPO membrane itself. They include important things like insulation, fasteners, and professional installation.
The complexity of your roof, including features like vents, skylights, and other penetrations, can also impact the final price. Additionally, factors like roof accessibility and local labor rates play a role in the overall cost.
How To Maintain The Lifespan Of Your TPO Roof
The key to getting the most value from your TPO roof lies in proper maintenance. Regular roof inspections by experienced professionals are very important, and we recommend scheduling these at least twice a year (generally in fall and spring). During these inspections, professionals will identify and repair any small problems before they develop into serious issues.
Keeping your TPO roof clean is very important for its energy-efficient properties. The white surface needs regular cleaning to maintain its reflective capabilities. However, make sure to use appropriate cleaning methods and avoid harsh chemicals that could damage the membrane.
Keeping gutters and drains clear is another critical aspect of TPO roof maintenance. Make sure that all drains and gutters are free from debris and clogs to prevent water pooling, which can result in premature aging and potential leaks. This is even more important in Wisconsin’s climate, where snow and ice can create additional drainage challenges.
How To Choose The Right TPO Roofing Membrane for Your Building
When you are choosing a TPO roofing system, there are various options available to meet different building requirements.
The standard white TPO remains the most popular choice, and it provides really nice reflectivity and energy efficiency. But if we talk about Wisconsin’s weather, where summers are not always hot, you can go for colored TPO roofing membranes like red, green, tan, and gray.
Membrane thickness is another important consideration. While 45-mil membranes are suitable for many applications, 60-mil options provide improved durability for high-traffic areas. Some manufacturers also offer 80-mil membranes for the best protection in severe weather conditions.

What Are The Different Installation Methods For TPO Roofs?
There are different installation methods for TPO roofing membranes. Here, we will quickly go over each of them!
#1 Fully Adhered
When we say “fully adhered,” we mean the TPO roofing membrane is glued down to the roof surface. A roofing glue or adhesive is spread across the roof, then the TPO membrane is carefully laid on top and pressed down.
This method works great because it creates a smooth, tight seal across the whole roof. It’s especially good for roofs in areas with strong winds because there’s no way for wind to get under the membrane.
However, it takes longer to install and costs more because of the adhesive needed.
#2 Mechanically Fastened
This method uses screws to hold down the roofing membrane. The fasteners are placed along the edges of the membrane sheets, and then the next sheet overlaps these fasteners and is welded down to create a water-tight seal.
This is generally faster and less expensive than the fully adhered method. It’s a popular choice for many buildings because it’s straightforward and effective.
The main drawback is that strong winds can cause the membrane to lift between the fasteners.
#3 Ballasted
Ballasted systems are the simplest – the TPO membrane is laid loose on the roof deck and then held down by weight. Generally, this weight comes from gravel or concrete pavers placed on top.
This method is quick to install and can be less expensive since you don’t need adhesives or lots of fasteners. However, it only works on roofs that are strong enough to hold all that extra weight.
Also, if there is a leak, it can be tricky to find because you have to remove all the ballast first to see the membrane.
If you aren’t sure about the right installation method for your TPO roof, it is best to ask your roofer.
