If you are thinking of replacing your commercial roof, there are many material options. The arrival of single-ply membranes has completely changed the roofing industry. These are lighter, stronger, and more durable than the traditional ‘layered’ systems.
Among these innovative solutions, TPO (thermoplastic polyolefin) roofing has emerged as a popular choice for commercial building owners. In fact, many new building owners and property managers are choosing a TPO roof for their next project.
As commercial roofing experts, we understand that choosing the right roofing material involves careful consideration of various factors – from climate conditions to budget constraints. In this comprehensive guide, we’ll examine various aspects of TPO roofs. Everything you need to know about this material will be covered here.
What Is A TPO Roof?
Before we assess whether TPO is the best roofing material around, let’s start with the basics. So, what is TPO? What does TPO stand for? Let’s get straight to it.
TPO roofing, short for thermoplastic polyolefin, is a type of single-ply roofing membrane. These are roofing systems made from sheets of rubber and other synthetics that can be chemically or mechanically fastened to insulation to create a durable, protective layer for your roof. The idea is to install a single layer that acts as a barrier to protect the building beneath it from leaks, weather, and other hazards.
TPO is one of the most popular single-ply roofing materials used today, especially for commercial buildings with flat or low-sloped roofs. TPO offers a streamlined, single-layer approach, unlike traditional roofs, which may have multiple layers. It’s typically white, which reflects sunlight and helps keep energy costs down.
How Long Does A TPO Roof Last?
The first thing you should know before you install a new roofing material is how long it lasts. TPO roofs last for about 20 to 25 years.
With high-quality materials and professional installation, some TPO roofs can even reach above 25 years. However, factors like climate, foot traffic, and maintenance frequency can influence its lifespan. This lifespan is respectable compared to other roofing alternatives available.
Routine inspections and timely repairs can help maximize a TPO roof’s longevity, ensuring it stays strong and protective over time.

How Much Does A TPO Roof Cost?
The cost of a TPO roof can be a bit higher than traditional materials. The cost of a TPO roof generally ranges from $6 to $12 per square foot, including both materials and installation. Though total costs can vary widely, a 10,000-square-foot commercial roof may land between $60,000 and $120,000. However, certain factors can push this higher or lower. Premium-grade TPO membranes, added insulation, or installation on a complex roof structure can increase costs.
Why Is TPO So Popular in Commercial Roofing?
TPO’s popularity has skyrocketed in recent years, especially for commercial buildings. Here are a few key reasons why many people consider it a top choice:
TPO Roofs Can Help You Save On Your Bills
As a commercial building owner, you are likely concerned about how much you are spending on your monthly utility bills. After all, the office needs to stay up and running all year round.
Installing a TPO roofing system can be a good option if you want to lower your energy bills. How? TPO membranes are often white or light-colored, which means they reflect sunlight rather than absorbing it. This UV resistance means TPO won’t deteriorate quickly under prolonged sunlight exposure.
This “cool roofing” effect can help reduce your building’s energy costs, especially in hotter climates, and can steer your business toward sustainability.
TPO Roofs Are Environment-Friendly
Continuing our discussion of sustainability, TPO roofs are a good option for environmentally conscious property owners. This single-ply membrane is often marketed as an environmentally friendly option because it doesn’t contain chlorine, which is harmful to the environment. Many TPO roofs are also recyclable at the end of their lifespan, making them a greener choice compared to some other roofing types.
TPO Roofing Systems Are Highly Durable
Durability isn’t just an added bonus when it comes to roofing—it’s essential, especially for commercial buildings. TPO roofs stand out in this department, and it’s one of the main reasons property managers and building owners favor it.
As we already know, TPO has an impressive lifespan thanks to its composition. TPO is a blend of rubber and other synthetic compounds. This combination creates a membrane that is naturally flexible and highly resistant to tears and punctures. So whether it’s a minor impact or some shifting equipment, TPO is built to handle some rough treatment. Additionally, TPO is resistant to certain chemicals, which is especially useful for buildings with rooftop HVAC equipment.
Comparatively Faster Installation
Another benefit that makes TPO great for commercial roofs is that it can be installed faster and more efficiently than other roofing materials.
For property owners, a quicker installation means less disruption to business operations and a faster timeline to get the building protected from the elements. It also translates to lower labor costs, as installers need less time on-site, which can lead to substantial savings for large buildings.
TPO’s straightforward installation process is a plus for contractors, too. The material is lightweight and flexible, which means it’s easier to maneuver on a roof. TPO sheets also come in wide rolls, allowing our roofers to cover large areas quickly with fewer seams to seal.
Are There Any Limitations Of TPO Roofs?
So, as we covered above, TPO roofs are a strong contender for the best single-ply membrane. But there are certain areas where it can lack.
Relatively New
Compared to other roofing materials like EPDM, which has been around for decades, TPO is relatively new to the commercial roofing scene. While TPO has shown strong performance in recent years, it doesn’t have as long a track record, which means we have less data on how it holds up over extended periods, especially in extreme climates.
Quality Variance
One drawback of TPO is that it’s available from multiple manufacturers, which can lead to variations in quality and performance. Some brands may produce stronger, longer-lasting TPOs than others, so the results can vary. To ensure you get the best out of your TPO roof, work with a reputable installer who uses a high-quality, trusted TPO brand.

TPO vs. Other Roofing Materials
To be called the best roofing material, you need to compare TPO with other popular options. In this section, we will pit TPO against other widely used single-ply roofing membranes: EPDM and PVC.
TPO vs. EPDM (Ethylene Propylene Diene Monomer)
EPDM is another popular single-ply roofing material, known for its flexibility and durability. It’s been around a bit longer than TPO and has a solid track record.
Material Composition:
While TPO is plastic-based (polypropylene) EPDM is a rubber-based membrane, which gives it excellent flexibility. This can be an advantage in colder climates where the roof may expand and contract with temperature changes.
Color and Energy Efficiency:
Unlike TPO, EPDM membranes are typically black, which absorbs rather than reflects heat. This can make EPDM less energy-efficient in hot climates but may be beneficial in colder regions where a bit of heat absorption helps.
Cost:
Cost is a major difference between TPO and EPDM. TPO is more expensive than EPDM rubber roofs. Even high-quality, thicker EPDM rolls are usually lower or are similarly priced to TPO, though the price can vary depending on the installation method and insulation requirements.
TPO vs. PVC (Polyvinyl Chloride)
PVC is another high-quality single-ply membrane that is widely used in commercial roofing. But unlike EPDM, PVC’s use in roofing came much later.
Material Composition:
PVC is a thermoplastic material, like TPO, but it includes additional polymers or ‘plasticizers’ that give it enhanced flexibility and durability. PVC is known for its excellent resistance to chemical exposure and grease, which can be beneficial for warehouses and factories.
Color and Energy Efficiency:
There is not much difference when it comes to aesthetics, as both roofing materials have a similar appearance. PVC also comes in white and other light colors, so it shares TPO’s energy-saving benefits.
Cost:
PVC is the most expensive single-ply membrane, costing more than both TPO and EPDM. However, some building owners find it worth the extra investment due to its durability and chemical resistance.
As you can see, each has its strengths, and what might be the “best” choice really depends on the specific needs of your building.
When Is TPO The Perfect Choice For Your Commercial Roof?
So, is TPO the best single-ply membrane for your commercial building? Here’s what to consider when deciding:
- Your Climate: If your building is in a hot area, TPO’s reflective qualities could help keep cooling costs down.
- Your Budget: TPO is generally affordable, but consider potential cost variations based on installation, insulation, and specific product quality.
- Foot Traffic: TPO can handle foot traffic well, but if your roof is constantly exposed to chemicals or grease, PVC might be worth the extra investment.
- Long-Term Goals: If you’re looking for a green roofing option, TPO’s recyclability and lack of chlorine might appeal to you.
