TPO Roofing Cost
TPO roofing costs $5.00 to $10.00 per square foot installed in 2026, or roughly $500 to $1,000 per roofing square (100 square feet). For a typical 10,000 sq ft commercial roof, expect a total installed cost of $50,000 to $100,000, including insulation, fasteners, and flashing. Price depends mainly on membrane thickness, attachment method, insulation, tear-off, and roof complexity. This page breaks down TPO roofing costs in detail.
TPO Cost Per Square Foot
Membrane thickness (measured in mils) is the biggest single driver of TPO material and installed cost.
| Membrane Thickness | Installed Cost (per sq ft) | Cost per Square (100 sq ft) | Typical Use |
|---|---|---|---|
| 45 mil | $5.00–$7.50 | $500–$750 | Budget commercial roofs, light foot traffic |
| 60 mil | $6.00–$9.00 | $600–$900 | Most common — best balance of cost and durability |
| 80 mil | $7.50–$11.00 | $750–$1,100 | High traffic, hail-prone regions, longest warranties |
Material alone (the membrane) runs roughly $1.50–$3.00 per square foot; the remainder is insulation, fasteners, adhesives, flashing, and labor.
Total TPO Roof Cost by Size
The table below estimates total installed cost for a 60 mil mechanically attached TPO system including insulation. Larger roofs usually have a lower per-square-foot cost due to economies of scale.
| Roof Size | Estimated Installed Cost (60 mil) |
|---|---|
| 2,000 sq ft | $13,000–$18,000 |
| 5,000 sq ft | $30,000–$45,000 |
| 10,000 sq ft | $50,000–$90,000 |
| 20,000 sq ft | $90,000–$170,000 |
| 50,000 sq ft | $200,000–$400,000 |
What Affects TPO Roofing Cost?
- Membrane thickness: 45, 60, or 80 mil — thicker membranes cost more but last longer.
- Attachment method: Mechanically attached is most economical; fully adhered costs more but improves wind resistance; ballasted adds material but reduces fasteners.
- Insulation: Polyiso insulation (for R-value and code compliance) often adds $1.50–$3.00 per square foot.
- Tear-off and disposal: Removing an old roof adds $1.00–$2.00 per square foot; recovering over an existing roof costs less.
- Roof deck repair: Rotten or damaged decking discovered at tear-off adds to the bill.
- Roof complexity: Penetrations, curbs, skylights, HVAC units, and parapet walls increase labor.
- Roof access and height: Tall buildings or poor access raise crane, hoisting, and labor costs.
- Region and season: Labor rates and demand vary by location and time of year.
TPO Cost vs Other Single-Ply Membranes
| Membrane | Installed Cost (per sq ft) | Notes |
|---|---|---|
| TPO | $5.00–$10.00 | Reflective, heat-welded seams, mid-priced |
| EPDM | $4.50–$9.00 | Often lower material cost; black absorbs heat |
| PVC | $6.50–$12.00 | Best chemical/grease resistance; premium price |

TPO Roof Repair Cost
Repairing a TPO roof is far cheaper than replacement:
- Small puncture or seam patch: $150–$500 per repair.
- Flashing or penetration reseal: $300–$800.
- Recoating an aging TPO roof: $1.00–$2.50 per square foot, extending service life several years.
Catching problems early during an annual inspection keeps repair costs low and avoids premature replacement.
Frequently Asked Questions About TPO Roofing Cost
How much does TPO roofing cost per square foot?
TPO roofing costs $5.00–$10.00 per square foot installed in 2026, depending on membrane thickness (45–80 mil), insulation, attachment method, and roof complexity. The membrane material alone is about $1.50–$3.00 per square foot.
How much does a TPO roof cost per square?
At roofing-industry pricing, a "square" is 100 square feet. TPO costs roughly $500–$1,100 per square installed, with 60 mil systems averaging $600–$900 per square.
How much does 60 mil TPO roofing cost?
60 mil TPO — the most common thickness — costs about $6.00–$9.00 per square foot installed. For a 10,000 sq ft roof, that is roughly $60,000–$90,000 including insulation.
Is TPO cheaper than EPDM?
TPO and EPDM are similarly priced, though EPDM often has a slightly lower material cost ($4.50–$9.00/sq ft installed vs $5.00–$10.00 for TPO). TPO's reflective surface can lower cooling costs, partly offsetting the difference in hot climates.
Why is my TPO roof quote so different from another?
TPO quotes vary based on membrane thickness, insulation R-value, whether tear-off is included, deck repairs, attachment method, and roof access. Always compare quotes line by line — see How to Read a Roofing Estimate.
