Roof Replacement Cost Calculator
Use this calculator to build a planning estimate for asphalt, metal, or premium roof replacements. Adjust for roof size and location, then compare the result with local written bids.
Estimated roof replacement cost
Enter your project details and calculate to see a planning estimate.
This is a planning estimate, not a contractor quote. Actual costs vary by location, home condition, material availability, permits, and project complexity.
Planning rates for cost year 2026 (national baselines × state regional factors). Not a contractor quote.
Main cost factors
Roof size
Material and labor scale with squares of roofing; larger or cut-up roofs cost more per job.
Material system
Architectural asphalt is the common baseline; metal and tile increase both material and specialty labor.
Regional labor rates
Coastal and high-cost metros often price above the national typical range for the same scope.
Material size-band baselines
Whole-project national band ~$9,000–$32,000 (typical ~$20,000). Rows below are material baselines (asphalt typical ~$14,000).

| Metal roofing baselineMaterial size-band baseline | $14,000 | $22,000 | $35,000 |

National average explanation
Whole-project national planning band: about $9,000–$32,000 in 2026 (typical near $20,000). Typical architectural-asphalt baseline: about $8,000–$22,000 (typical near $14,000). Material table rows are those baselines—not a second whole-project typical. Your calculator result applies size, material, and a regional multiplier on top of those assumptions.

Frequently asked questions
How accurate is a roof cost calculator?
- It is a planning tool, not a contractor quote. Actual prices depend on pitch, layers to tear off, decking repairs, access, and local labor rates.
What inputs matter most?
- Roof area (or home footprint with stories), material type, and region usually move the estimate the most. Steep slopes and multi-layer tear-offs also matter.
Should I still get in-person bids?
- Yes. Use the calculator to set a budget range, then collect at least three detailed bids with matching scope and warranties.
Methodology & estimate disclaimer
Production model: roof area × material rate × regional × pitch × complexity, plus removal, skylights, and permit allowance.
Actual costs vary by location, home condition, material availability, permits, and project complexity. Read our methodology, the national cost bands table, editorial policy, and disclaimer. Planning provenance uses the internal model and, where listed, public datasets for context—not invented third-party bid averages.
