TPO vs. PVC Roofing: Which Single-Ply System Is Right for Your Louisville Business?


Why Single-Ply Systems Matter for Louisville Businesses

Roofing systems are an important part of a business’s infrastructure that, ideally, you rarely have to think about. Flat roof replacement, while a headache, is also an opportunity to invest in a low-maintenance system that works for you.

Most commercial and industrial businesses have flat or low-slope roofs. For these roofs, single-ply roofing systems are a popular choice for their affordability, durability, and energy efficiency.

TPO and PVC are the most common single-ply commercial roofing materials. However, there are some important differences in the qualities of TPO and PVC roofing. We’ll walk through the benefits and drawbacks of both materials to help you make an informed choice. 

What Is TPO Roofing?

“TPO” is short for thermoplastic olefin, one of the most common single-ply roofing membranes used on commercial buildings. TPO is a synthetic plastic manufactured in long sheets, making it relatively easy and efficient to install. These sheets are unrolled on the rooftop, attached to the roof structure, and then heat-welded at the seams to form a watertight seal. 

TPO’s affordability is a major benefit, but it’s not the only one. It’s also an energy-efficient roofing system, also known as a “cool roof.” Often manufactured in bright white, TPO roofing reflects sunlight rather than absorbing it. This keeps the interior temperature of the building cooler, reducing energy use.  

Depending on specific conditions, TPO roofing typically has a 20 year lifespan. As a plastic polymer, it’s resistant to punctures from debris or weather. However, TPO has lower chemical and fire resistance than PVC roofing.

Highland Roofing’s work on the Main Street Apartment Building in Louisville is a great example of a TPO roofing application.

What Is PVC Roofing?

PVC roofing is another popular single-ply roofing membrane, short for polyvinyl chloride. As a single-ply membrane, it has some similarities to TPO roofing. However, rather than a rubber polymer, PVC is a vinyl polymer. Its different physical properties make it best suited for slightly different applications than TPO roofing. 

Installation is similar to TPO roofing; PVC comes in sheets that can be heat-welded together to become watertight. PVC is also a great cool roof choice, often manufactured in white to reflect sunlight. Unlike TPO, though, PVC is softer and slightly less resistant to punctures and therefore may require more frequent maintenance. 

PVC roofing has superior fire and chemical resistance to TPO. It also tends to have a slightly longer lifespan of around 20-30 years. These different characteristics tend to come at a higher price, however.

For applications that require extra durability, this price tag may be worth it. However, it’s not necessary for every commercial use.

TPO vs. PVC: Side-by-Side Comparison

Both TPO and PVC are excellent roofing choices for commercial and industrial buildings with low-slope roofs. They’re easy to install and maintain, in addition to being an energy-efficient choice. However, for specific commercial or industrial needs, one material might be a better fit than the other. 

TPO Roofing

  • Cost: TPO is an affordable roofing choice, with lower installation costs than many other materials. 
  • Durability: TPO roofing is puncture-resistant, holding up against hail and other poor weather. However, depending on the specific product, it is not as resistant to chemicals and fire risk. 
  • Best for: Balancing affordability, energy efficiency, and durability.

PVC Roofing

  • Cost: Compared to TPO, installing PVC tends to be pricier. However, for businesses that require extra durability, installation cost may be balanced by lower maintenance costs.
  • Durability: PVC is highly resistant to chemicals, grease, and fuels. It’s also naturally fire-resistant making it ideal for restaurant applications.
  • Best for: Facilities with frequent chemical exposure or fire risk that also prioritize energy efficiency.

Which Roofing System Is Right for Your Louisville Business?

Choosing the right roofing system comes down to balancing cost, both initially and long-term, with durability. Ultimately, TPO is more affordable, but is less fire- and chemical-resistant. PVC has superior fire and chemical resistance, but is pricier. Making the right choice depends on your priorities and the specific needs of your business. 

For general applications, such as office buildings, warehouses, and retail applications, TPO is typically well-suited. These businesses generally don’t encounter the same fire risk and exposure to chemicals as other industries. TPO is affordable and keeps energy costs low during hot Louisville summers. 

For restaurants, factories, and other industrial facilities, PVC will likely have better long-term ROI. Frequent exposure to grease and chemicals wears on less durable roofing systems. More frequent maintenance eventually overcomes the initial cost difference. Like TPO, PVC roofing systems are a great choice to reflect the blazing summer sun.
