What is TPO Roofing? Frequently Asked Questions

November 21, 2023

Getting a new roofing system for a flat roof can be overwhelming. If you’re thinking about getting TPO roofing, you may be curious about how it works, why it's beneficial, or what makes it a popular choice for flat roofs.

In this post, we’ll answer the top 10 questions we get about TPO roofing, explain in better detail what it is, and look at factors that influence the cost of a TPO roofing system.

1. What is TPO Roofing?

TPO stands for thermoplastic Olefin. It’s a single-ply roofing membrane renowned for its durability, leak resistance, and energy efficiency. Composed of a blend of polypropylene and ethylene-propylene rubber, TPO is a relatively environmentally friendly roofing option with excellent durability and efficiency.

2. Why Choose TPO Roofing Over Other Options?

TPO roofing boasts a myriad of benefits over many other flat roofing products. It has excellent UV resistance, can help improve the energy efficiency of your building, and is relatively easy for your roofing company to install. 

3. How Long Does TPO Roofing Last?

Typically, TPO roofing lasts about 20-30 years. Different brands of TPO roofing vary in quality, thickness, and durability. Depending on the brand you go with, the lifespan and required maintenance for your roof will vary.

4. Is TPO Roofing Suitable for My Building?

TPO roofing is very versatile. Most flat-roof buildings accommodate TPO roofing well. The type of building and flat roof you have will determine if your roof is compatible with TPO.

5. What Colors Are Available for TPO Roofing?

TPO typically comes in variations of white, black, and gray. Because TPO is known for its energy-efficient qualities, white tends to be the most common color. White is reflective and helps UV rays and heat bounce off of the roof, helping to keep your building cooler in hot weather while also insulating when it is cold outside.

6. How is TPO Roofing Installed?

TPO installation involves prepping the roof surface for installation, attaching the membrane to the roof, and seam welding to seal the roof from leaks or other issues. TPO requires specific equipment and expertise for installation and should always be installed by a professional roofing company.

7. Does TPO Require Maintenance?

TPO is relatively low maintenance in comparison to other roofing materials, but it does require some upkeep. Regular inspections and debris removal are key to keeping up with your TPO roof. Proactivity is the best way to prevent roofing issues in the long run.

8. Can TPO Withstand Harsh Weather?

In general, yes, it can. TPO is designed to stand up to extremely high and low temperatures, resist high winds, and hold up against precipitation and hail. It is also a very flexible material, meaning it expands and contracts with temperature changes without breaking. It is a great choice for diverse climates that experience a variety of weather conditions.

9. How Does TPO Make Buildings More Energy Efficient?

TPO contributes to energy efficiency in buildings because of how reflective it is. It not only reflects heat, but it also reflects UV rays to keep your building cooler in the warmer months. This can lead to cost savings on energy bills.

10. Is TPO Roofing Environmentally Friendly?

Yes. TPO roofing is recyclable and able to reduce energy consumption in buildings. TPO contributes to more sustainable building practices and is a more environmentally-conscious roofing option than some other materials.

TPO Cost Considerations

With any roofing system, the customizations and variables you choose will influence the cost of your roof. Here are a few things that can change the cost of your TPO roofing system.


Not all TPO systems are created equal! TPO is one of the most cost-effective roofing options available, but different manufacturers use different processes and materials that can affect cost. They also come in different thicknesses, which can determine not only the cost but the longevity of your roof.

Adhesive/Adherence Options

Most roofing companies and contractors use one of three types of adhesion for TPO roofs. TPO can be attached using special adhesives, fasteners, or with a ballast system. The adhesion method preferred by your roofer will affect the cost. Specialized adhesives are the most durable option, but they can be more expensive.

Season of Installation

Typically, roofing companies are busiest during warm weather and following severe weather events like heavy rain, hail, snow, or tornadoes. During peak times like these, some companies may charge more to help manage demand. Avoiding busy periods for roofing companies may help you save on costs.
