Repair cost calculator
Enter what is being repaired and how much of it. The result is a low-to-high planning range with the assumptions printed next to it — not a contractor quote, and not a market price.
$325–$800
Scenario midpoint $575 — not a typical market quote.

Assumptions in this number
- A minimum job charge sets the low end: small repairs still carry travel, setup and disposal time.
Included in this range
- Investigation at each reported leak location
- Basic sealing or a small patch where the entry point is confirmed
- Cleanup of the immediate working area
Excluded from this range
- Ceiling, insulation or drywall repair inside the home
- Underlayment or deck replacement if the decking is saturated
- Mould remediation and interior repainting
What an inspection can change
Where water enters often differs from where the stain appears, and a second entry point is common. An on-site inspection can change the scope in either direction.
Next step
This range is a planning estimate. Quote requests open only where a participating company has confirmed coverage and an agreement for that work — so this page does not ask for your details today.

Rates are provisional editorial assumptions pending validation against licensed market data. This is a planning band, not a contractor quotation.

What sits behind the number
The arithmetic
- 1. Quantity × the category's rate band (US dollars per unit).
- 2. Multiplied by the access factor you selected.
- 3. Multiplied by 1.35 if you applied temporary-protection pricing.
- 4. Raised to the category's minimum job charge if the result is lower.
- 5. Widened by 10–25% when an answer is "not sure", and stated next to the result.
- 6. The low end is rounded down and the high end up to the nearest $25, so the arithmetic result always sits inside the band.
The quantity is always the amount of repair — leak locations, linear feet, or square feet of affected area. It is never the floor area of the house.

Every rate, its unit and the evidence behind it
Published in full so the number can be argued with. If a rate looks wrong for your area, that is useful information: it is a national editorial band, not a local price.
Verification status: provisional, unvalidated
Model v1.0 was written and reviewed on 2026-11-10. It is a planning device built from editorial judgement about how repair work is scoped. It is not a market-price calculator, and it is not based on invoices, claim payouts or a licensed market report.
Currency: USD. Geography: United States, national band. Not localised, not ZIP-specific.
What the rates are based on
- Editorial judgement about how repair work is scoped and priced, written as explicit per-unit rates.
- Nothing else. No invoices, no claim payouts, no market report, no contractor survey.
What would make these rates defensible
- Written invoices or estimate records from at least three licensed companies, with dates, ZIP codes and itemised scope.
- A stated basis for the per-unit rate in each category (labour hours plus material cost, or a priced line item).
- A documented regional split, so a national band is not presented as a local price.
- An independent second pass over the arithmetic and the rounding rules.
Each rate, its unit and how it was set
| Repair type | Rate per | Band | How the band was set |
|---|---|---|---|
| Leak investigation and repair | leak locations | $260–$640 | Set in November 2026 as a judgement band for investigating one location and making a small repair: the low end reflects a short diagnostic visit with a minor seal, the high end a half-day of work with access equipment.Unit: Per reported leak location, not per square foot. Not used: No invoice data, no insurer payouts, no market report. |
| Flashing repair or replacement | linear feet | $24–$58 | A per-linear-foot band covering removal, new material and tie-in. The band widens with the detail being replaced: a headwall or chimney is not the cost of a short run of step flashing.Unit: Per linear foot of flashing actually replaced. Not used: No invoice data; no allowance derived from material price lists. |
| Damaged or missing shingles | square feet of affected area | $9–$20 | A per-square-foot band for removing and replacing shingles in a defined area, before any decision about matching a discontinued product. Material factors are multipliers on that band, not separate price lists.Unit: Per square foot of shingle area replaced. Not used: No shingle price list, no invoice data, no labour-rate survey. |
| Metal roof detail repair | linear feet | $22–$52 | A per-linear-foot band for detail work on an existing metal roof: gaskets, fasteners, sealant and minor seam adjustment. Panel replacement is deliberately outside the model.Unit: Per linear foot of the affected detail line. Not used: No proprietary system pricing; no invoice data. |
| Flat roof patch or local repair | square feet of patch area | $8–$19 | A per-square-foot band for a local patch with terminations, plus a separately stated minimum charge because flat-roof visits rarely scale down.Unit: Per square foot of patch area. Not used: No membrane price list; no invoice data. |
| Custom scenario | square feet of affected area | $7–$24 | A wide band that spans the other categories, published so a visitor with an unclassified problem still gets a planning figure with visible uncertainty rather than a made-up one.Unit: Per square foot of affected area, which is a poor unit for this category by design. Not used: Nothing category-specific — this row is an envelope, not a price. |
Each row also states the evidence that would replace it. Until that evidence exists, the band stays labelled provisional everywhere it appears.
Known limitations
- A national band cannot represent a local market, an unusual house or an unusual defect.
- Repair work is priced per job far more often than per unit, so the band is a planning device, not a quotation format.
- Access and material factors are multipliers on an unvalidated base, so they inherit that uncertainty.
