What Is TPO Roofing?
Thermoplastic polyolefin (TPO) roofing is a single-ply membrane made from a blend of polypropylene and ethylene-propylene rubber. Developed in the 1980s as a cost-effective alternative to PVC roofing, TPO comes in thicknesses of 45, 60, and 90 mils (1 mil equals 0.001 inches).
TPO works best on flat or low-sloped roofs and does a great job of kicking heat away from your house. The bright white surface reflects up to 80% of the sun’s rays, helping to keep summertime cooling bills in check.
TPO Roofing Cost Factors
Just like PVC or EPDM, TPO costs depend on materials and labor, with labor often accounting for the most significant portion of the budget. The factors below outline how various aspects, from roof size to insulation choice, can impact your total cost.
Roof Size
The larger your roof, the higher the cost of TPO roofing will be. Plan on paying between $4.50 and $16 per square foot, depending on the size of your project.
| Roof Size (Sq. Ft.) | Average Cost Range |
|---|---|
| 200 | $2,000–$3,500 |
| 500 | $2,500–$8,500 |
| 1,200 | $5,500–$20,400 |
| 1,500 | $6,750–$24,000 |
| 2,000 | $9,000–$34,000 |
| 3,000 | $14,000–$40,000+ |
Labor
Roofers charge $3 to $7 per square foot—or $75 to $120 per hour in some markets—to install TPO roofing. If you live in a high-cost area, expect rates on the upper end. Because labor can eat up as much as 70% of the budget, get at least three quotes before you sign a contract.
Additional labor costs may also arise if access to the roof is challenging and you need to remove the old roof before installing a new TPO roof.
Installation Method
TPO roofing offers several installation methods. You have three ways to attach the membrane, each with its own price tag:
Ballasted attachments cost $1.50 to $2.50 per square foot. Here, the membrane is weighed down by river-washed stones or pavers.
Fastened roofs cost $2 to $3 per square foot. This method uses screws to attach the membrane to the decking or underlayment.
Adhered roofs cost $2.75 to $3.50 per square foot. Roofers use an adhesive to bond the membrane to the decking or underlayment.
Insulation Choice
Your roofer will add insulation before rolling out the membrane. Depending on the thickness and type, expect to pay between $1.60 and $4.20 per square foot for the cost to install insulation. The table below outlines the most common options and their average pieces.
| Insualtion Type | Average Cost (per Sq. Ft.) |
|---|---|
| Polyisocyanurate (PolyISO) | $1.60–$2.40 |
| Extruded polystyrene (XPS) | $1.60–$2 |
| Fiberboard | $2.50–$15 |
| Expanded polystyrene (EPS) | $3–$4.20 |
Membrane Thickness
TPO membranes are available in 45-mil, 60-mil, and 90-mil thicknesses. The thicker the membrane, the higher the material cost, though lifespan depends more on material quality than thickness.
Roof Penetrations and Accessories
Every chimney, skylight, or vent your roofer works around adds time and materials to the project. Budget for a $1 to $50 per penetration.
Does TPO Roofing Increase Home Value?
Installing TPO roofing can increase your home value, especially if you have a flat or low-sloped roof. TPO offers enhanced energy efficiency, durability, and minimal maintenance, all of which appeal to prospective buyers. While it doesn’t provide the curb appeal of other materials, its functional benefits are a strong selling point for energy-conscious buyers.
DIY TPO Roof Installation vs. Hiring a Pro
You might save on labor by installing the roof yourself, but it’s not recommended. TPO requires heat-welded seams, specialized tools, and strict code compliance—one mistake can lead to leaks or void your warranty. A licensed local roofer brings the gear, training, and insurance needed to keep both you and your home safe.
