General TPO Roof Installation Cost In 2025

So without any further ado, let’s have a look at what property owners generally spend on TPO roofs. You can expect to spend around $4.50 to $16 per square foot for TPO roof installation. For a typical 1,500-square-foot commercial roof, this translates to approximately $6,500 to $24,000, with most property owners paying around $10,700 on average.

But this is just a general estimate, the exact cost of installation for your property depends on many other factors that we will discuss in the next section of our article.

What Are The Factors That Affect TPO Roof Installation Costs?

#1 Roof Size

The size of your roof is the most important thing affecting TPO roofing costs per square foot. Larger roofs naturally need more materials and more time to install, but they may benefit from economies of scale, meaning the TPO cost per square foot may decrease slightly with larger projects. For example:

• Small roof (250 to 500 square feet): $1,000 to $5,000
  
• Medium roof (1,000 to 1,500 square feet): $4,000 to $15,000
  
• Large roof (2,000+ square feet): $8,000 to over $20,000

Using a TPO roofing cost calculator can help you estimate prices based on your specific roof dimensions.

#2 Material Thickness

TPO membrane thickness affects durability and price. Thicker TPO roofing membranes provide better puncture resistance and have longer lifespans. 

• 45-mil TPO: $1 to $1.50 per square foot (material only)
  
• 60-mil TPO: $1.50 to $2.50 per square foot (material only)
  
• 80-mil TPO: $2.50 to $3 per square foot (material only)

Most commercial buildings benefit from 60-mil TPO, offering a balance between cost and durability.

#3 Installation Method

The membrane roof attachment method significantly impacts your TPO installation cost.

• Ballasted system: $1.50 to $2.50 per square foot (materials only)
  
• Mechanically fastened: $2 to $3 per square foot (materials only)
  
• Fully adhered: $2.75 to $3.50 per square foot (materials only)

Fully adhered systems provide better wind resistance and fewer seams but cost more than other methods. However, they can prevent expensive leaks down the road, making them worth considering.

#4 Insulation

Insulation represents about 25% of your TPO roofing price. Different types include:

• Extruded polystyrene (XPS): $1.60 to $2 per square foot
• Polyisocyanurate (Polyiso): $1.60 to $2.40 per square foot
• Expanded polystyrene (EPS): $3 to $4.20 per square foot
• Fiberboard: $2.50 to $15 per square foot

The thickness of insulation affects both price and energy efficiency. Better insulation can lower your heating and cooling bills over time.

#5 Roof Complexity and Penetrations

Roof penetrations like chimneys, vents, skylights, and HVAC units increase the complexity and cost of TPO roofing installation. Each penetration requires special flashing and detailing to prevent leaks, adding $1 to $50 per penetration to your total TPO roof cost.

#6 Removal of the Existing Roof

If your project requires removing old roofing materials, expect to pay an extra $1 to $2 per square foot. This cost includes labor and disposal fees for the old roofing system.

#7 Geographic Location

Your location affects labor rates and material shipping costs. Areas with higher costs of living typically have higher TPO roofing costs per square foot. Additionally, remote locations may incur higher transportation costs for materials.

#8 Contractor Experience and Reputation

Experienced contractors with strong reputations may charge more but they often deliver better quality work. When comparing quotes, consider the contractor’s experience with TPO roofing specifically, as proper installation is crucial for performance over time.

How To Lower TPO Roof Installation Costs?

You can reduce your TPO installation cost without compromising quality. You can schedule your installation during the off-season (late fall or early spring) when roofing contractors might offer discounts. Get at least three quotes from experienced contractors to find the best value. Consider the least expensive recommended insulation type that meets your needs.

If your existing roof is in good condition, ask if a TPO overlay is possible rather than a complete tear-off, saving on removal costs. Finally, regular maintenance after installation will extend your roof’s lifespan, giving you better long-term value from your investment. 

Remember that the cheapest option isn’t always the most cost-effective in the long run. Quality materials and proper installation prevent expensive repairs later.
