Your claim wasn't denied — it was shrunk. The contractor says $18,000. The insurer's check says $9,400. The missing $8,600 vanished into a line item called "depreciation." This is the most common way insurers reduce payouts, and most policyholders accept it without a fight. Here's how the game works — and how to dispute it.
Most homeowners policies pay in two stages:
The game is in the depreciation number. Insurers routinely over-depreciate: a 12-year-old roof depreciated 60% when its rated life is 25 years, "like kind and quality" materials priced at bargain-bin rates, labor rates pulled from a national database instead of your local market. Each assumption shaves hundreds or thousands off your check.
The insurer calculated a depreciation figure — make them show their math. In writing, request:
You paid for the policy; the calculation behind your payout is your business. Vague answers ("our system calculates it") are not acceptable — push for the worksheet.
Once you have the worksheet, check these three inputs — this is where the money hides:
Two to three independent contractor estimates do double duty: they establish the real replacement cost and they give you a professional who will state the roof's condition in writing. When your contractor's $18,000 meets the insurer's $11,000, the gap itself becomes the dispute — documented, specific, and hard to wave away.
Send a formal underpayment dispute letter that:
Our Denied Claim Appeal Kit ($24) includes a ready-made depreciation/underpayment dispute letter with [BRACKET] fields for your numbers — plus the adjuster call script for the follow-up phone call, where most of these disputes actually get resolved.
After repairs are complete:
This second check is often 30–50% of the total payout. Policyholders who skip this step leave thousands on the table.
Take a typical hail-damaged roof. Honest replacement cost from two local contractors: $18,000. The insurer's estimate: $11,000 replacement cost, then 40% depreciation on a 12-year-old roof with 25-year shingles, minus a $2,500 deductible. Check: $11,000 − $4,400 (depreciation) − $2,500 (deductible) = $4,100.
Now audit the levers: the roof's rated life is 25 years, so 12 years is 48% of life — but depreciation was set at 40% of cost while pricing bargain materials the roofer would never install. Correct the material pricing to like-kind-and-quality (+$3,000), correct the labor to local rates (+$2,000), and challenge the condition assumption with maintenance photos. The revised number lands near $12,700 — an $8,600 swing from the same roof, the same policy, the same facts. That's the dispute, and it's winnable in writing.
Almost every homeowners policy contains an appraisal clause: if you and the insurer disagree on the amount of loss (not whether it's covered), either side can demand appraisal. Each side picks an appraiser, the two pick an umpire, and the panel sets the number. Key points:
It depends on your policy — common windows are 180 days to 2 years from the date of loss or the date of the initial payment. This deadline is separate from your appeal window and it's the one policyholders miss most often, because by then the roof is fixed and the claim feels "done." Put it on the calendar the day you receive the first check: recoverable depreciation deadline, with a reminder 30 days before. If repairs legitimately can't be completed in time (contractor backlog after a major storm is a valid reason), request an extension in writing before the deadline expires — insurers routinely grant them when asked early and deny them when asked late.
Aggressive depreciation crosses into bad faith when the insurer: refuses to provide the worksheet, uses demonstrably wrong useful-life figures after you've corrected them, or delays the recoverable depreciation release without cause. At that point, a state insurance department complaint and an attorney consultation are the right escalation — both are covered in the kit's escalation flowchart.
