Are you considering TPO for your upcoming flat or low-slope roof replacement? Is your biggest how much TPO roofing costs?
TPO (thermoplastic polyolefin) roofing is a single-ply white membrane mainly used in commercial roofing. However, with modern home designs and more complex roof with flat sections are on the rise, TPO is becoming common in residential roofing.
Unfortunately, it's hard to find TPO roofing information geared towards residential, especially around pricing. Let's change that.
For over 35 years, Bill Ragan Roofing has taken pride in helping homeowners understand the budget they'll need for their upcoming roofing project. So, let's break down everything you need to know about the cost of TPO roofing.
By the end of this article, you'll have the answers to:

How much does TPO roofing cost?
Including labor and materials, installing TPO roofing will cost around $12.00 to $17.00 per square foot in 2025. Obviously, the size of the roof determines where you'll fit in the price range.
However, the cost per square foot will trend towards the higher end of the price range on smaller projects. This is because TPO roofing comes in rolls, so smaller roofs require more cutting, fitting, and other finer details to prevent leaks.
With that in mind, the table below gives you a better idea of TPO roofing's cost based on the area's square footage.
Square Footage |
TPO roofing cost in 2025 |
| Under 500 square feet | $17.00 per square foot |
| 500 to 1000 square feet | $14.00 per square foot |
| Over 1,100 square feet | $12.00 per square foot |
Just keep in mind that it’s impossible to give you an exact price due to all the different cost factors (more on this next). However, you'll find most TPO roofs will cost around the price range above.
What factors impact TPO roofing's cost?
At this point, you have an idea of how much TPO roofing costs in 2025. The roofing contractor you hire and your area's supplier prices play a huge role in the cost, but there are many things that must be considered when estimating a TPO roof.
Let's break down all the factors that impact TPO roofing's cost.
Labor costs
Labor costs are factored into every line item on an estimate. So, if anything takes time and labor, it adds to the labor costs of a TPO roof.
Unfortunately, there’s no set price for labor and time because it depends on the roofing contractor you hire. But the more manpower and time it takes to replace your roof, the higher the cost.
Square footage of the roof
As I've already mentioned, the square footage of the roof plays a huge role in TPO roofing's cost. It affects the amount of materials used, labor, and time needed to complete the job.
I say square footage because it’s what homeowners are familiar with. However, you’ll also hear a roofing contractor say “price per roofing square” (100 square feet).
Residential or commercial project
While it plays into square footage, whether the roof is residential or commercial can affect TPO roofing's cost. Remember, the cost per square foot will trend towards the higher end of the price range on smaller projects.
So, commercial TPO roofs actually end up being cheaper per square foot than residential TPO roofs. This doesn't mean it'll be cheaper overall, but residential roofs are more complex and require more attention to detail that usually increase labor costs.
Insulation type and other components
A big cost factor is the type of insulation and amount being installed under the TPO roofing membrane. Insulation that’s thick enough to insulate the entire structure costs more than using fabric insulation and gluing the membrane to it.
Another thing that always factors into pricing is the other components that are included with a membrane roof system. However, this depends on how the TPO roof is being installed.
Tearing off and dump fees
During the tear-off process, the old TPO membrane and other components are ripped up until there's only a clean roof deck. So, there will be a labor cost associated with tearing off the old roof.
However, the torn off debris also must be loaded into a dump truck or trailer to be taken to a dump of the contractor’s choice. The dumpsites charge significant fees for this service, so there will also be a dump fee and labor cost for the crew member(s) doing the work.
Accessibility
Roofers use a roof access point for every single piece of the roof replacement process. The harder your roof is to access, the more it impacts your TPO roof's cost.
Things like landscaping below the roofline, patio area, a fence, and how far away the materials and dump truck are a few examples of what makes a roof hard to access. Simply put, the more obstacles they have to work around to get the job done increases labor and time costs.
Roof penetrations
A roof penetration is anything that comes through your roof, like plumbing vents, gas vents, kitchen/bathroom vents, skylights, and chimneys. The more penetrations your roof has, the more it impacts the cost.
This is especially true for flat roofing, which doesn't have enough pitch to drain. Smaller pipes or vents won’t impact much, but skylights and chimneys add more to a new roof’s cost because they take longer to flash and work around.
What other flat roofing materials should you consider?
After reading this article, you now know how much TPO roofing costs and the things that directly impact pricing. Just remember, you won't get a 100% exact estimate until after an inspection from a roofing contractor.
But before reaching out to one, are sure TPO roofing is right for you? The truth is, you can’t make the best decision without knowing all the options available.
In fact, there's still more to learn about TPO roofing. That’s why I wrote another article breaking down the best options for a residential flat or low-slope roof system.
