TPO roofing costs typically range from $8,250 to $13,125 , but many homeowners will pay around $10,700 on average for a 1,500-square-foot roof. Thermoplastic polyolefin (TPO) roofing—a single-ply rubber roofing material best suited for low-sloped or flat roofs—is most commonly featured on commercial buildings, but it’s growing in popularity among homeowners for its energy-efficient design. The material is typically white, which helps reflect up to 80% of the sun’s heat and radiation.

This guide outlines the costs of TPO roofing and how to hire a professional roofing company. We also offer guides on metal roof installation costs and tile roof pricing if you want to learn more about other types of roofing systems.

Major Cost Factors of TPO Roofing

The cost of a TPO roof depends on various factors, such as the size of your roof, the materials you choose, and the installation process.

Factor 1: Cost by Roof Size

A roof’s size plays a critical role in determining its replacement cost, as larger roofs require more materials, labor, and time.

Here are the costs of TPO roofing by roof size:

Roof SizeCost Range of InstallationAverage Cost of Installation
1,000 sq ft$5,500–$8,750$7,150
1,500 sq ft$8,250–$13,125$10,688
2,000 sq ft$11,000–$17,500$14,250
2,200 sq ft$12,100–$19,250$15,675
2,500 sq ft$13,750–$21,875$17,813

Factor 2: Cost by TPO Size

TPO is most commonly available in gauges of 45 mils, 60 mils, and 80 mils, which are .045 inches, .06 inches, and .08 inches thick, respectively. For example, a GAF 80-mil TPO full-size roll is 10 feet by 100 feet, and a half-size roll is 5 feet by 100 feet. Thicker membranes and larger rolls are more expensive than smaller alternatives.

Factor 3: Cost by Insulation Material

Before installing the TPO membrane, you’ll need insulation, which accounts for roughly 25% of the project’s total cost. Prices range from $1.60 to $15 per square foot, depending on the type of insulation.

Here’s a breakdown of the most common insulation materials and their costs:

Insulation Material Cost RangeAverage Cost
Polyisocyanurate (PolyISO)$1.60–$2.40 per sq ft$2.00
Extruded polystyrene (XPS)$1.60–$2.00 per sq ft$1.80
Fiberboard$2.50–$15 per sq ft$8.75
Expanded polystyrene (EPS)$3.00–$4.20 per sq ft$3.60

Factor 4: Cost by Installation Method

Prices for installation range from $1.50 to $3.50 per square foot depending on related attachment methods; the thickness of the membrane can also be a factor. There are three installation methods:

Below are installation methods and how much they cost:

Installation MethodCost RangeAverage Cost
Ballasted attachment$1.50–$2.50 per sq ft$2.00
Fastened roof$2.00–$3.00 per sq ft$2.50
Attached roof (fully adhered)$2.75–$3.50 per sq ft$3.13

Factor 5: Cost of Labor

Labor costs fall between $3.50 and $5.25 per square foot or $75 to $90 per hour. Expect to pay more if the roofing company needs to remove and dispose of the older roof and less if your roof is in good condition.

Professional vs. DIY TPO Roofs

If you’re deciding whether to tackle TPO roof installation as a DIY project or hire a professional, consider the following:

Professional

We recommend hiring a professional roofing company to install your TPO roof. It’s a dangerous task, and roofing requires knowledge of local building codes. If you make a mistake, you could void your home insurance policy.

Here are some additional benefits of hiring a pro:

DIY

Installing your own TPO roof can save you $3 to $7 per square foot, but we don’t recommend DIYing a TPO roof unless you have professional experience. If your roof does not have the type of slope necessary to support TPO roofing, you should not proceed with the project, as it could lead to leaks and other issues.

Our Recommendation

TPO is a relatively new roofing material developed as an alternative to PVC roofing and is best suited for slow-sloped or flat roofs most commonly associated with commercial buildings. TPO roofing costs depend on the material’s quality, the project’s complexity, and the professional roofers you hire to do the job.

TPO Roofing Cost FAQ

How much does a roll of TPO cost?

The cost of a roll of TPO depends on its quality and the thickness of the TPO membrane. The average TPO roofing material is $2.00 to $3.50 per square foot, including the insulation, flashing, and other tools and supplies needed for the roofing project.

How long does a TPO roof last?

The average TPO roof has a life span of 15 to 20 years but can last for as long as 30 years with regular maintenance. Frequent roof inspections and timely repairs will extend the life of your roof and help you save on roof replacement expenses.

Which costs more: TPO or EPDM?

TPO roof installation costs more than other materials such as EPDM (ethylene propylene diene monomer) and PVC. TPO has a higher resistance to punctures and can help you save money on energy costs.

Can TPO roofing be installed over shingles?

Yes, you can install a new TPO roof over existing shingles, but the current roof must be in good condition and able to support the weight of the TPO roof. Check out our shingle roof pricing guide for more information.
