Compare the covered scope first, then the payment calculation. An approved claim need not match a contractor's quote. Deductibles, depreciation, limits and conditions on later payment all need their own explanation.
Mike had the roofer's estimate open while Dave read the insurer's assessment. The totals were different, and everyone had started discussing depreciation. Then Mike found the first mismatch: one document described the whole roof; the other described one plane. We had been arguing about the subtraction before agreeing what was being bought.
Ask the adjuster to put the settlement basis and each deduction in writing. Have the complete policy and endorsements available, not just the declarations page. The declarations page is useful, but it does not contain every rule.
Replacement Cost and Actual Cash Value
IBC's glossary explains that actual cash value can be determined using replacement cost less depreciation or other valuation approaches. In ordinary conversation people often shorten that to "what the old roof is worth". The policy's definition is the one that matters for your claim.
Replacement-cost coverage generally concerns the cost of replacing covered property under the contract's terms. It does not make every proposed improvement a covered expense. Nor should you assume the wording for contents, the whole dwelling and a roof-specific endorsement is identical.
Ask whether the roof has a separate settlement schedule or endorsement. If so, ask which document applies and why. There is no useful universal depreciation percentage to apply to every roof in Ontario.
Put the Amounts in the Right Order
Ask the adjuster to walk through the figures in this order:
- The work accepted as covered damage.
- The valuation basis applied to that work.
- Each deduction or limit.
- Any additional payment that depends on later action.
Then place the contractor's matching base scope beside it. Keep optional upgrades on a separate line. This will not make every disagreement disappear, but it prevents a higher-grade shingle choice from being confused with a deduction for the existing roof's condition. It also shows which question needs the contractor and which needs the insurer.
The calculator cannot reconcile two different jobs
We returned to those two roof scopes and marked the difference. If the contractor says the repair cannot be limited to one plane, what is the technical reason? What evidence has gone to the insurer, and has it been reviewed? Dave stopped trying to solve the discrepancy with a calculator. It was doing excellent sums on two different jobs.
Our quote-reading guide can help you compare line items. A clear contractor estimate and a clear insurance assessment make disagreements easier to locate.
Read a Settlement in the Right Order
Clarify accepted damage before comparing the insurer's calculation with a replacement quote.
Covered scope
Identify which damage and repair items the insurer accepts.
Valuation
Check replacement-cost or actual-cash-value terms and any roof endorsement.
Adjustments
Ask how depreciation, limits, deductible and payment conditions apply.
Owner's decision
Compare the written settlement with the contractor's actual scope.

Is This the First Payment or the Final One?
Some policies or settlements may make further payment conditional on repair or replacement, documentation and deadlines. Ask whether depreciation is recoverable in your case, what action is required, and when. Do not assume another homeowner's experience applies to your contract.
Confirm how the deductible is applied and whether the proposed payment is an initial amount or a final settlement. If a mortgage lender is named on a payment, ask the insurer and lender about the process before relying on immediate access to the funds.
Before setting the paperwork aside, Mike added one more question: what happens if opening the roof reveals concealed damage? Establish the documentation and supplemental-review process while there is time to understand it. Photographs and a written change description are easier to collect during the work than reconstruct after the materials are gone.
Before committing, you should be able to explain the covered work, the present payment, any conditional later payment and your own remaining cost. If one part is unclear, resolve that specific line with the insurer or contractor who controls it.
