TPO Membrane Roof System Cost (2026)
TPO Membrane Roof System runs about $19,012–$23,040 installed for a typical 2,400 ft² roof at a 2:12 pitch, at national-average rates: $3.75/ft² material plus $2.50/ft² labor, with a 20-year warranty. It applies to flat and low-slope roofs (2:12 pitch or below), where shingles and tile can’t be installed.
State labor rates move this range up or down (see the state cost guides), and your roof's actual geometry moves it more. The estimator measures it from satellite free.

Methodology & Caveats
These are planning-grade ranges, deliberately conservative: material, labor, and disposal are priced per ft² of true roof area (flat area × pitch multiplier), then adjusted by a regional cost index. The range applies ±10% on materials and ±15% on labor around the regional midpoint.
Regional index: National Average. Source: planning-grade v1 (public cost indexes + BLS wage patterns).
Your actual roof's size, pitch, and complexity move the number more than any table can. Measure it free with the estimator. A final price always requires an on-site inspection.
