Quick answerQuick answer: Most homeowners pay $6,500 to $24,000 to install a TPO roof, averaging about $10,700, or $4.50 to $16 per square foot (HomeAdvisor). TPO costs roughly the same as EPDM and less than PVC. Membrane thickness and attachment method — ballasted, fastened, or adhered — both move the price.
  • The typical TPO roof installation costs $6,500 to $24,000, averaging about $10,700 nationally for a 1,500-square-foot roof (HomeAdvisor, This Old House).
  • Per square foot, TPO runs $4.50 to $16 installed — close to EPDM at $4.25 to $13, and cheaper than PVC at $5.50 to $15 (Fixr).
  • Attachment method changes labor cost: ballasted is cheapest at $1.50 to $2.50 per square foot, fully adhered the priciest at $2.75 to $3.50 (HomeAdvisor).
  • Thicker membranes cost more — Fixr's breakdown shows 65-mil membrane pricing higher than 45-mil across every attachment method, from ballasted ($1.80-$2.50 vs. $2-$2.50) to fully adhered ($2.50-$3.20 vs. $2.80-$3.50).

What affects the cost?

  • Attachment method — ballasted systems run $1.50 to $2.50 per square foot, mechanically fastened $2 to $3, and fully adhered $2.75 to $3.50, the priciest labor method (HomeAdvisor)
  • Membrane material — TPO runs $4.50 to $14 per square foot installed, EPDM (rubber) $4.25 to $13, and PVC $5.50 to $15, the most expensive of the three single-ply options (Fixr)
  • Membrane thickness — thicker membranes cost more per square foot; Fixr's single-ply thickness breakdown shows 45-mil ballasted at $1.80 to $2.50 versus 65-mil ballasted at $2 to $2.50, with the same pattern for mechanically attached ($2-$2.50 versus $2.50-$3) and fully adhered ($2.50-$3.20 versus $2.80-$3.50) systems (Fixr)
  • Total roof size — HomeAdvisor's size-based pricing runs $2,000-$3,500 for a 200-square-foot roof up to $14,000-$40,000+ for 3,000 square feet
  • Insulation — adds $1.60 to $4.20 per square foot depending on type: polyisocyanurate $1.60-$2.40, extruded polystyrene $1.60-$2, fiberboard $2.50-$15, expanded polystyrene $3-$4.20 (HomeAdvisor)
  • Labor rates — labor runs $3 to $7 per square foot or $75 to $120 per hour and can account for up to 70% of the total budget (HomeAdvisor); Fixr's comparable single-ply data shows labor near 50% of the total, at $2.50 to $11 per square foot or $45 to $75 per hour
  • Roof penetrations and flashing — each penetration (vents, pipes, skylights) adds $1 to $50 (HomeAdvisor)

How much does a TPO roof cost?

A typical TPO roof installation costs $6,500 to $24,000, averaging around $10,700 for a 1,500-square-foot flat or low-slope roof (HomeAdvisor). This Old House cites the same $10,700 national average, so the two sources agree closely on the headline number. Broken down per square foot, HomeAdvisor puts installed TPO at $4.50 to $16, while Fixr’s TPO-specific figures run lower, at $3 to $9 per square foot with an average project cost of $5,235 to $9,525 — a smaller-scale estimate than the national HomeAdvisor/This Old House figure, but consistent in shape. For unusually large or complex roofs, HomeAdvisor notes projects can run as high as $40,000.

Is TPO cheaper than EPDM or PVC roofing?

TPO sits in the middle of the three main single-ply flat-roof membranes, and it’s close to EPDM in price. Fixr’s material comparison puts TPO at $4.50 to $14 per square foot, EPDM (rubber) at $4.25 to $13, and PVC at $5.50 to $15 — meaning EPDM is very slightly cheaper on average, and PVC is the most expensive of the three. Thumbtack’s rubber-roof data, which is EPDM-specific, backs this up: it prices EPDM installation at $5.67 to $7.53 per square foot, or $14,165 to $18,825 for a 2,500-square-foot roof — squarely inside the same price band TPO and PVC occupy. In practice, the choice between the three often comes down to heat reflectivity, seam-welding quality, and puncture resistance rather than price alone, since the ranges overlap so heavily.

Does membrane thickness or attachment method change the price?

Both do, and they’re the two biggest levers after material choice. Attachment method drives labor cost the most: ballasted systems (membrane held down with stone or pavers) are cheapest at $1.50 to $2.50 per square foot, mechanically fastened membranes run $2 to $3, and fully adhered systems — glued down for maximum wind resistance — cost the most at $2.75 to $3.50 per square foot (HomeAdvisor). Membrane thickness adds its own increment on top of that: Fixr’s single-ply thickness breakdown shows 45-mil membrane running $1.80 to $2.50 per square foot ballasted versus $2 to $2.50 for 65-mil, and the same pattern holds for mechanically attached ($2-$2.50 vs. $2.50-$3) and fully adhered ($2.50-$3.20 vs. $2.80-$3.50) installs. Thicker membrane resists punctures and UV wear better, which is why it costs more both in material and in the labor to handle it.

How can you lower the cost of a TPO roof?

  • Choose a ballasted or mechanically fastened system over fully adhered if your roof structure and local wind codes allow it — ballasted installation runs $1.50 to $2.50 per square foot versus $2.75 to $3.50 for fully adhered (HomeAdvisor).
  • Stick with a standard 45-mil membrane instead of upgrading to 65-mil unless you need the extra puncture resistance — 65-mil runs higher per square foot across every attachment method (Fixr).
  • Compare TPO against EPDM directly for your project size, since the two run nearly identical per-square-foot ($4.50-$14 for TPO versus $4.25-$13 for EPDM per Fixr) and the cheaper option can shift by contractor and region.
  • Budget insulation separately and ask what’s included. Insulation type swings from $1.60 to $15 per square foot depending on material (HomeAdvisor), so confirm which type is quoted before comparing bids.
  • Get multiple quotes, since labor alone ranges from $2.50 to $11 per square foot across sources (Fixr, HomeAdvisor) — a meaningful swing on a large roof.

Prices vary by region, roof size, and complexity, so treat the figures above as a planning budget. Get two or three local quotes, and confirm whether tear-off of the old roof, insulation, and flashing are included before committing to a final number.

Frequently asked questions

How much does it cost to install a TPO roof?
Most homeowners pay $6,500 to $24,000, averaging about $10,700 for a typical 1,500-square-foot flat or low-slope roof (HomeAdvisor, This Old House). Per square foot, expect $4.50 to $16 installed (HomeAdvisor).
Is TPO roofing cheaper than EPDM?
They're close. EPDM (rubber) runs $4.25 to $13 per square foot versus TPO's $4.50 to $14 in Fixr's material comparison — EPDM edges slightly cheaper at both ends, but the ranges overlap heavily.
Is TPO cheaper than PVC roofing?
Yes. PVC runs $5.50 to $15 per square foot versus TPO's $4.50 to $14 (Fixr), making PVC the priciest of the three single-ply membrane options.
Does membrane thickness affect the price?
Yes — thicker membranes cost more labor and material per square foot. Fixr's single-ply breakdown shows 45-mil ballasted membrane at $1.80 to $2.50 per square foot versus 65-mil ballasted at $2 to $2.50, with a similar step-up for mechanically attached and fully adhered systems.
What's the cheapest attachment method for a TPO roof?
Ballasted systems are cheapest at $1.50 to $2.50 per square foot. Mechanically fastened runs $2 to $3, and fully adhered — the most labor-intensive method — costs $2.75 to $3.50 (HomeAdvisor).
How much of a TPO roof's cost is labor?
HomeAdvisor puts labor at $3 to $7 per square foot or $75 to $120 per hour, accounting for up to 70% of the total budget. Fixr's comparable single-ply data shows labor closer to 50% of the total, at $2.50 to $11 per square foot or $45 to $75 per hour.
Does insulation add to the cost of a TPO roof?
Yes, insulation is typically priced separately at $1.60 to $4.20 per square foot depending on type — polyisocyanurate runs $1.60 to $2.40, extruded polystyrene $1.60 to $2, fiberboard $2.50 to $15, and expanded polystyrene $3 to $4.20 (HomeAdvisor).
Why do TPO roof cost estimates vary so much between sources?
Fixr's TPO-specific figures ($3 to $9 per square foot, $5,235 to $9,525 average project) run lower than HomeAdvisor and This Old House's shared national average of $10,700 with a $6,500 to $24,000 range — likely reflecting a smaller or more basic install assumption versus a broader national sample that includes larger, more complex roofs.

Labor $3 to $7 per square foot or $75 to $120 per hour, up to 70% of the budget. Installation method: ballasted $1.50-$2.50/sq ft, fastened $2-$3/sq ft, adhered $2.75-$3.50/sq ft. Insulation $1.60-$4.20/sq ft (polyisocyanurate $1.60-$2.40, extruded polystyrene $1.60-$2, fiberboard $2.50-$15, expanded polystyrene $3-$4.20). Roof penetrations $1 to $50 each.
  • Fixr — TPO roofing costs between $3 and $9 per square foot. An average TPO roof can cost anywhere from $5,235 to $9,525.
  • Fixr — National average cost for installing a rubber (EPDM) roof is between $9,000 and $18,000 (average $15,000), or $4.25 to $13 per square foot. By membrane thickness: 045 mils ballasted $1.80-$2.50/sq ft, 065 mils ballasted $2-$2.50/sq ft, 045 mils mechanically attached $2-$2.50/sq ft, 065 mils mechanically attached $2.50-$3/sq ft, 045 mils fully adhered $2.50-$3.20/sq ft, 065 mils fully adhered $2.80-$3.50/sq ft. Comparable materials: TPO $4.50-$14 per sq ft, PVC $5.50-$15 per sq ft. Labor $2.50-$11 per square foot or $45-$75 per hour, around 50% of the total cost. Sealing $1-$2.50 per sq ft; customization $1-$5 per sq ft.
  • This Old House — TPO roofing costs $4-$10 per square foot. The national average cost for a 1,500-square-foot roof is $10,700.
  • Thumbtack — Rubber (EPDM) roof costs $14,165-$18,825 for a 2,500-square-foot installation, averaging $5.67-$7.53 per square foot. By size: 1,000 sq ft $5,670-$7,530; 1,500 sq ft $8,505-$11,295; 2,000 sq ft $11,340-$15,060; 3,000 sq ft $17,010-$22,590. For 2,500 sq ft: materials $4,235-$7,095, labor $9,685-$11,485, equipment $245. Material cost $1.69-$2.83 per square foot.

HomeAdvisor and This Old House closely agree on the headline figure for a typical 1,500-square-foot roof: both cite a national average of $10,700, with HomeAdvisor's normal range at $6,500-$24,000 (broader range $2,000-$40,000 for unusual jobs). Fixr's TPO-specific article reports a lower average project cost ($5,235-$9,525) and a narrower per-square-foot range ($3-$9), which likely reflects a smaller or more basic install assumption than HomeAdvisor/This Old House's national sample. national_average_usd, range_low_usd, and range_high_usd are anchored to the HomeAdvisor/This Old House cluster since two independent sources converge on the same figures. unit_low_usd/unit_high_usd ($4.50-$16 per sq ft) also come from HomeAdvisor and roughly bracket Fixr's TPO figure ($3-$9) at the low end and its TPO-vs-EPDM-vs-PVC comparison figure ($4.50-$14 for TPO) at the high end. For material comparison, Fixr's rubber-roof cost page gives directly comparable per-square-foot figures for TPO, EPDM, and PVC single-ply membranes, which anchor the by_type rows. Thumbtack's rubber-roof data (EPDM-specific: $5.67-$7.53/sq ft, $14,165-$18,825 for 2,500 sq ft) is not TPO-specific but corroborates that EPDM sits in the same general price band as TPO and PVC, consistent with Fixr's material comparison. Figures are for materials and standard installation labor; tear-off of an existing roof, extensive insulation replacement, and structural repairs are commonly quoted as separate line items.
