If you have a commercial property and need a new roof, you’re probably wondering what material is best for your building. PVC vs. TPO roofing is a popular debate when it comes to commercial properties. Both materials offer advantages, but which one should you choose for a new build or roof replacement?
This guide will help you understand the pros and cons of both roofing systems so you can make the right decision for your building.
At All Elements, we’re experts at installing TPO and PVC roofs, so whichever you choose, you’ll be in good hands. Learn more about our commercial roofing services and how we can help with repairs, replacements, and inspections.
What is the Difference Between TPO and PVC Roofing?
Before exploring what sets TPO and PVC apart, it’s helpful to understand some of the similarities. Both roofing materials are:
- Manufactured in rolled sheets that are applied to the roof.
- Typically white, which is ideal for reflecting heat and keeping buildings cooler.
- Resistant to punctures and tears.
- Waterproof, but slippery when wet.
When comparing TPO vs PVC, the main difference is how the material is made and how it performs.
What is PVC Roofing?
PVC stands for polyvinyl chloride. While it’s often associated with plumbing pipes, PVC is used for a wide array of applications. For roofing, it’s made with two PVC layers that have a polyester reinforcement layer in between. The top is made with UV-resistant additives, while the bottom contains plasticizers that make the material more flexible and therefore easier to install.
What is TPO Roofing?
TPO is made from thermoplastic polyolefin. Though slightly newer than PVC roofing, it has quickly gained popularity in the commercial roofing industry. TPO sheets are made with a reinforced polyester mat that aids in installation. They are manufactured with UV inhibitors, flame retardants, and biocides that prevent mold, rodents, and insects.
Durability and Lifespan of PVC vs. TPO Roofing
PVC and TPO roofing are known for their strength and durability. However, there are benefits and drawbacks to both.
- Chemical Resistance: PVC has outstanding chemical resistance, whereas TPO is susceptible to damage from grease and oil, such as cooking oil that may get deposited on the roof at restaurants.
- Strength: TPO has a higher tear strength and break strength than PVC, meaning that it is a stronger material.
- Durability: Because of its higher resistance, TPO typically withstands hail and other severe weather better than PVC.
- Fire Resistance: When it comes to fireproofing, both materials have similar properties, as both are manufactured with flame-retardant additives.
- Extreme Heat: PVC is more susceptible to shrinking or expanding in extreme temperature changes.
It’s not just about the material you choose. Proper installation and maintenance can significantly impact a roof’s longevity, regardless of which material you choose.

Energy Efficiency and Environmental Impact
PVC and TPO are known for their energy efficiency. PVC roofing is highly reflective, which means it can reduce the heat your building absorbs. This can lower energy costs while keeping your employees and customers comfortable.
Duro-Last, a leading manufacturer and supplier of single-ply PVC roofing membranes, offers reflective and durable roofing systems that improve energy efficiency and reduce waste. Utilizing the post-industrial scrap from its manufacturing process, the company recycles this leftover material into new membranes, offering commercial owners a sustainable roofing option.

Cost and Installation Considerations
TPO roofing is typically less expensive than PVC roofing, making it a more budget-friendly option for building owners. Although PVC roofing tends to be more expensive, your roof is an investment, no matter what material you choose.
Installation methods also differ between the two materials. PVC roofing requires hot air welding, which can be more complex and time-consuming, so hiring a professional is key!
TPO roofing can be installed using various methods, including hot air welding, adhesive, and mechanical fastening. But again, proper installation is the only way to ensure your roofing system, regardless of its material, is built to last.
