How Much Does TPO Roofing Cost? [2026 Data]

In 2026, the national average cost to install TPO roofing on a 1,500-square-foot flat or low-slope roof is $10,700. Most homeowners pay between $6,500 and $24,000, with the spread driven by roof size, number of penetrations like chimneys and vents, and local labor rates.

Roof Size: How Much Does TPO Roofing Cost per Square Foot?

Roof size is one of the biggest drivers of your total TPO roofing cost, so use your home's actual square footage rather than national averages when budgeting. According to the United States Census Bureau, the average new home measured 2,200 square feet in 2020, but your home may be significantly smaller or larger. Smaller roofs tend to cost slightly more per square foot than larger ones, so costs vary meaningfully by size, the table below shows how installed prices break down across common roof sizes.

Roofing Contractor Costs: What Do Pros Charge?

TPO roofing labor typically runs $3 to $7 per square foot, with the higher end applying when the installer must remove old roofing or add insulation. Some contractors charge by the hour instead, with roofing labor ranging from $75 to $120 per hour. Because TPO installation requires specialized training and experience, expect your project to land toward the upper end of that hourly range.

Cost by Location: Where Are Prices Highest?

Where you live can meaningfully affect what you pay for TPO roofing, with higher costs appearing in both dense urban markets and remote areas. In cities, elevated costs of living push labor and overhead higher, while remote locations add expense through long material transport distances and a limited pool of roofing pros who offer TPO installation.

Additional TPO Roofing Cost Factors

There are a number of factors that determine how much you'll pay for TPO roofing beyond the size of your roof. The specific brand, insulation type, attachment type, customizations, and more can all add to your project cost.

Material

TPO is a newer rubber roofing material made from a blend of synthetic rubber and fillers such as talc and fiberglass, and because each manufacturer's formula differs, prices per square foot can vary significantly from brand to brand. For context, a rubber roof installation costs between $6,000 and $18,000, making it a useful benchmark when comparing TPO quotes.

Roll Size

TPO membranes come in a range of widths and thicknesses, each carrying its own price point, so the roll size your project requires will directly affect material costs. Common widths are 4, 6, 10, and 12 feet, with thicknesses of 45, 60, and 90 mils, and as a general rule, longer and thicker rolls cost more.

Insulation Material

Insulation is a significant budget line for TPO roofing, accounting for roughly 25% of the total installation cost, and the type you choose affects both performance and price. Costs vary by insulation material, as the breakdown below shows.

PolyISO is the most popular choice for insulating a flat-top roof. Prices vary based on thickness (either 1 or 4 inches thick, generally speaking) and the R-value, the material's ability to resist heat flow.

Flashing

TPO roof flashing is a specialty product, similar to what you'd find on other low-slope roof types like torch-down roofs, made from metal pieces with a TPO exterior or form-specific TPO material that bonds directly with the membrane during installation. Your roof will need flashing at every junction where walls meet the roof plane and at any penetration for plumbing, air vents, or chimneys. These costs are separate from the base roofing price and range from a few dollars each up to $50 per item, depending on the complexity of the penetration.

Attachment Type

The attachment method you select affects your per-square-foot TPO cost, with three main options available: ballasted, fastened, and fully-adhered. Costs also shift based on membrane thickness, since costs vary by both method and thickness as shown in the table below.

The prices of these options can vary based on the thickness of the membrane, with most membranes measuring at 45 mils or 65 mils. For reference, one mil is 0.001 inches. Membranes that are 65 mils will fall at the higher end of the price range, while 45-mil membranes will fall on the lower end.

Customizations

Customizations such as roof penetrations for vents, electrical conduits, piping, chimneys, and skylights can add $5 to $50 each to your TPO roofing cost, depending on the complexity of each penetration. If your project requires multiple add-ons, these individual costs can accumulate quickly, so factor them into your budget before finalizing a quote.

Why You Should Hire a Roofer

You'll spend an extra $3 to $7 per square foot when you hire a local roofing pro, but this isn't a job you can DIY. Installing your own roof poses a safety risk, and improper work can lead to leaks and result in costly damage.

Here's why it's ideal to hire a TPO roofing pro

There are a few reasons you should forgo this DIY and hire a roofer to install a TPO roof:

• Roof repairs come with a risk of falls and injury, but pros have the tools to do it safely.

• TPO roofing requires the right roof slope, which a pro can assess.

• Improper roof installation can lead to leaks and damage your home.

• DIYing your roof may void your homeowner's insurance.

• Pros have insurance and may offer warranties that can help protect your investment.

TPO Roof Replacement vs. Repair

TPO roof repair can cost anywhere between $600 and $3,000, depending on the extent of the damage, the repair area, and the complexity of the repair. TPO repair is a fairly straightforward process, and a roofing repair pro with experience working with this material can fix damage quickly. In cases of widespread damage or for a TPO roof that's more than 20 years old, a full replacement may be more cost-effective in the long run.

How to Save Money on the Cost to Install a TPO Roof

While it may be tempting to save on a TPO roof by attempting to install it yourself or use a budget material, there are better ways to cut costs that won't potentially lead to bigger problems.

• Schedule your roof installation during an off-season. Some roofing contractors offer discounts during slow times like late fall or early spring.

• Get a quote from at least three experienced contractors to find the best deal.

• Choose the least expensive recommended insulation type.

Does a TPO Roof Increase Home Value?

A new roof will help when it comes time to sell your home due to the energy savings, low likelihood of upcoming repairs, and extended time before expected replacement. While TPO roofing isn't a particularly stylish aesthetic choice, a new, well-installed, durable roof will always be a plus if you're putting your home on the market.
