RoofRangeBaseCost to replace a roof
“Cost to replace a roof” is how people phrase a redo in plain English — old covering off, new system on, dumpsters and labor included in real bids. This page uses the replacement model: squares, material, tear-off on by default, bands dated 2026-07. Asphalt mid all-in near $650 per square and metal mid all-in near $1,150 per square are the planning anchors before steep pitch or deck rot shove you toward high. It mirrors roof replacement cost with verb-first wording for searchers who type “replace” before “replacement.” The math does not change — only the framing. No lead form; written local scope still governs the check you sign.

When to use — and when not to
When to use
You are googling replace language before calling roofers. A neighbor said what they paid and you want the same math on your squares. Comparing asphalt replace cost to metal on the same house.
When not to
Patch leak → roof repair cost. Brand-new deck → new roof cost. Calculator UI preference → roof replacement cost calculator. Casual “redo” wording → redo roof cost.
Assumptions
Tear-off on for typical replace path. Asphalt mid all-in near $650/sq; metal mid all-in near $1,150/sq with tear-off (2026-07). Deck plywood not itemized inside mid.
Worked examples
19 squares asphalt mid, tear-off on
Mid ≈ 19 × ($500 + $150) = $12,350
Regional labor can sit above national mid.
19 squares metal mid, tear-off on
Mid ≈ 19 × ($1,000 + $150) = $21,850
Replace cost jumps with material — not just verbs.
How it calculates
replace ≈ squares × (material_$ + tearoff_$)
Replace path — removal band plus new covering on the same squares.
- Size the roof in squares — pitched surface, not downstairs footprint alone.
- Pick asphalt, metal, or flat for the new field.
- Keep tear-off on unless a code-approved overlay is documented.
- Compare mid to written replace bids line by line.
Common traps
- Cheap replace bids may omit tear-off — ask explicitly.
- Plywood rot after strip is extra — keep contingency.
- Gutters often separate from replace scope.
- Insurance replace checks use carrier math — not this band.
