If you are replacing a flat commercial or residential roof, you must choose between the "Big Three" single-ply membranes: TPO, EPDM, and PVC. Each has distinct chemical properties, installation methods, and price points. Use this calculator to compare pricing between any two membranes.
One roofing square = 100 square feet
Total TPO Membrane Cost
$13,200.00
Total PVC Membrane Cost
$16,500.00
PVC Membrane is more expensive.
Visual difference between TPO Membrane and PVC Membrane.
Measure or confirm the required geometric inputs before calculation.
Calculate the plan/base value from your measured inputs.
Use rise/run geometry or form-specific factors to convert to true sloped scope.
Translate outputs into practical units such as squares, pieces, or roll counts.
Verify complex intersections, accessories, and local requirements before procurement.
For complex roofs, run plane-by-plane geometry and accessory checks before final material ordering.
Most ordering mistakes happen when assumptions are mixed across units, pitch, and coverage rules. Using TPO vs EPDM vs PVC Roofing Comparison early helps align scope, quantity, and labor planning before supplier pricing or installer scheduling. This reduces reorders, avoids under-counting, and improves quote consistency.
Start with verified dimensions, run conservative waste assumptions, then compare output against product data sheets and field conditions. For cross-checks, pair this page with EPDM vs PVC roofing and TPO roofing estimator.
Treat calculator output as a controlled estimate, then validate accessories, overlaps, and edge details separately. Final checks are stronger when you review assumptions with Single ply roofing cost calculator before submitting purchase orders.
No, EPDM is generally the cheapest single-ply membrane. However, TPO is very close in price and has gained massive market share because its white color reduces cooling costs. For better estimating accuracy, cross-check roof area, pitch multiplier, and material quantity with your project notes, then confirm waste planning before final ordering. This keeps your field measurement aligned with real site.
PVC is inherently more flexible and chemically resistant than TPO. It has a longer track record in the industry (dating back to the 1960s), whereas TPO formulations are still evolving. You pay a premium for PVC's proven longevity. For better estimating accuracy, cross-check roof area, pitch multiplier, and material quantity with your project notes, then confirm waste planning before final.
EPDM is the easiest for a homeowner to repair using seam tape and primer. TPO and PVC repairs require a specialized hot-air welding gun to melt a patch onto the existing membrane, which usually requires a professional. For better estimating accuracy, cross-check roof area, pitch multiplier, and material quantity with your project notes, then confirm waste planning before final ordering.
Planning. Use outputs for budgeting and early scope, then verify dimensions and specifications before procurement. For better estimating accuracy, cross-check roof area, pitch multiplier, and material quantity with your project notes, then confirm waste planning before final ordering. This keeps your field measurement aligned with real site conditions and reduces costly quantity revisions.
Accuracy depends on input quality. Better field measurements and realistic assumptions produce better results. For better estimating accuracy, cross-check roof area, pitch multiplier, and material quantity with your project notes, then confirm waste planning before final ordering. This keeps your field measurement aligned with real site conditions and reduces costly quantity revisions.
Yes. Most roofing workflows include waste to cover cuts, breakage, and layout inefficiencies. For better estimating accuracy, cross-check roof area, pitch multiplier, and material quantity with your project notes, then confirm waste planning before final ordering. This keeps your field measurement aligned with real site conditions and reduces costly quantity revisions.
Usually no. Most projects need supporting checks for pitch, area, accessories, and costs. For better estimating accuracy, cross-check roof area, pitch multiplier, and material quantity with your project notes, then confirm waste planning before final ordering. This keeps your field measurement aligned with real site conditions and reduces costly quantity revisions.
Validate dimensions, pitch, overlaps, accessory counts, and local installation requirements. For better estimating accuracy, cross-check roof area, pitch multiplier, and material quantity with your project notes, then confirm waste planning before final ordering. This keeps your field measurement aligned with real site conditions and reduces costly quantity revisions. Recheck dimensions, product coverage, and install requirements before purchase.
