Roof replacement cost calculator
This is the calculator-labeled twin of roof replacement cost — same redo engine, UI copy aimed at people who typed “calculator” first. Size the roof, pick material, leave tear-off on for an honest replacement path, read low / mid / high stamped 2026-07. Asphalt mid all-in near $650 per square ($500 install + $150 tear-off) and metal mid all-in near $1,150 are the planning anchors before steep access or premium product shove you toward high. Deck rot and permit fees still live outside the national table. Carry mid into appointments; keep high for extra layers, two-story access, or standing-seam step-ups.

When to use — and when not to
When to use
You want the tool interface with replacement defaults, not the essay landing. Comparing asphalt versus metal on the same squares with tear-off already on.
When not to
Patch-only leak → roof repair cost. First install on clean deck → new roof cost calculator. National average article framing → average roof replacement cost. Verb-first search → cost to replace a roof.
Assumptions
Tear-off defaults on. Asphalt mid $500/sq + tear-off mid $150/sq ≈ $650/sq all-in; metal mid all-in roughly $1,150/sq with tear-off (2026-07). Permits and gutters not itemized.
Worked examples
20 squares asphalt mid, tear-off on
Mid ≈ 20 × ($500 + $150) = $13,000
Steep two-story access often lands high.
20 squares metal mid, tear-off on
Mid ≈ 20 × ($1,000 + $150) = $23,000
Same squares — material toggle drives the spread.
How it calculates
replacement ≈ squares × (material_$ + tearoff_$) × complexity
Replacement calculator path — field re-cover with tear-off on unless you know otherwise.
- Enter squares or sq ft of roof surface.
- Pick asphalt, metal, or flat for the new covering.
- Leave tear-off enabled for typical redo; disable only with a written overlay plan.
- Read low / mid / high and compare every bid’s installed total.
Common traps
- Overlay bids may skip tear-off — verify code where you live.
- Three layers force strip — bias tear-off high or add contingency.
- Magazine averages often hide whether tear-off was included.
- Permits and ridge vent show on real invoices — ask in/out on bids.
