RoofRangeBaseRedo roof cost
“Redo” is kitchen-table language for the same job sales decks call replacement — strip the old field, install new covering, haul debris. This page frames that redo with tear-off on and 2026-07 bands so you can compare neighbor anecdotes to your squares. Asphalt mid all-in near $650 per square ($500 install + $150 tear-off) is the common planning anchor; metal mid all-in near $1,150 per square is the step-up on the same footprint. If the deck is brand new with nothing to remove, new roof cost is the honest page — redo assumes something came off unless you toggle otherwise. No lead form, no “get free redo quotes” blast — planning math only until a written scope arrives.

When to use — and when not to
When to use
Someone said they redid their roof for X and you want that number on your footprint. Budgeting a full re-cover after inspection bad news. Comparing redo quotes that claim to bundle tear-off.
When not to
Small leak patch → roof repair cost. First install on clean framing → new roof cost. Formal “replacement” search → roof replacement cost. Tear-off-only strip without reinstall → roof tear off cost.
Assumptions
Tear-off on by default for the redo story. Asphalt and metal tables match the rest of the site (2026-07). Overlay-only bids need an explicit local code check — the default mid assumes removal.
Worked examples
21 squares asphalt mid redo (tear-off on)
Mid ≈ 21 × ($500 + $150) = $13,650
Neighbor “redo” stories may hide product grade — ask shingle type.
21 squares metal mid redo
Mid ≈ 21 × ($1,000 + $150) = $24,150
Redo with metal is still full tear-off plus premium install.
How it calculates
redo ≈ squares × (material_$ + tearoff_$)
Redo math — tear-off band plus reinstall on the same squares.
- Enter roof squares for the house section being redone.
- Select new material — asphalt mid remains the common redo default.
- Leave tear-off on for an honest redo; disable only with a written overlay plan your city still allows.
- Read low / mid / high before you sign redo paperwork.
Common traps
- Redo sales calls sometimes skip inspection — get deck truth first.
- Two-story steep redo lands high — national mid is not your pitch.
- Magazine redo averages mix markets — run your squares.
- Warranty on a redo depends on scope — price alone does not tell coverage.
