ACV pays depreciated value. RCV pays full replacement cost minus deductible. On a 15-year-old asphalt roof, the gap is 60-70% of the total settlement — meaning ACV may pay $4,000 on a $14,000 replacement while RCV pays the full $11,500 (after a $2,500 deductible). The two-stage holdback mechanic on RCV policies is what most homeowners miss until the first check arrives smaller than expected.
How depreciation works
Most carriers use straight-line depreciation across the material's expected service life. The math is simpler than the policy language suggests.
A 30-year architectural shingle at year 15 has used 50% of its expected life. The carrier depreciates 50%, leaving 50% of replacement cost as the ACV. At year 20, you're at 33% remaining. At year 25, ~17%. Adjusters apply this through proprietary depreciation tables — usually Xactimate-aligned — that may differ from the pure straight-line estimate by 5-10 percentage points either way, depending on the material's documented condition prior to the loss.
A worked example. Your roof: 15-year-old 30-year architectural asphalt. Replacement cost (2026 typical): $14,000. Depreciation at 50%: $7,000. Deductible: $2,500. ACV settlement: $14,000 − $7,000 − $2,500 = $4,500. RCV settlement (full): $14,000 − $2,500 = $11,500. The gap is $7,000 — the depreciation withheld on ACV.
The depreciation holdback — the part most homeowners miss
On RCV policies, the carrier doesn't write you a single check for the full $11,500. They write two:
- Initial check (ACV portion): $4,500 issued within 30-60 days of claim acceptance.
- Depreciation holdback: $7,000 held back until you submit proof of completed repairs — usually a paid contractor invoice, post-repair photos, and a completion certification. The deadline is typically 180 days from the date of loss, sometimes 12 months.
Miss the deadline and the depreciation holdback is actually forfeit. You keep the $4,500 and the carrier closes the file. This is the hidden trap on RCV: if you're cash-flow tight and can't front the repair until insurance pays, you can end up effectively on an ACV settlement despite buying RCV coverage.
The mechanical fix: most reputable contractors will accept the initial ACV check as a deposit, complete the work, then collect the depreciation directly from the carrier as a third-party payee on completion. Build that into the contract before signing.
Why insurers are pushing roofs onto ACV-only endorsements
Roof claim severity has spiked in hail and hurricane markets — specifically Colorado, Texas, Florida, Louisiana, and increasingly Oklahoma and Kansas. Carriers' loss ratios on roofs over 10 years stopped penciling. The response, since roughly 2020-2022: a "Roof Surface Settlement" endorsement added at renewal that downgrades roofs over 10 years (sometimes 15, sometimes 20) from RCV to ACV-only.
The endorsement is often added with no premium reduction. The carrier's rationale is risk-priced; the homeowner's experience is silently losing 60-70% of replacement value at the moment of claim. Read your renewal documents specifically for "Roof Surface" or "Roof Settlement" or "Cosmetic Roof" endorsements. If one was added at the last renewal, you may be on ACV-only for the roof regardless of what the dwelling-coverage line says.
This is reference, not a quote. The asymmetry between coverage you bought 5 years ago and coverage you have now is the single most common surprise in claim conversations.
How to read your declarations page
Three lines to find before anything else:
- Coverage A — Dwelling: look for "Replacement Cost" or "Actual Cash Value" suffix.
- Loss Settlement: the basis applied to property losses. "Replacement Cost — Loss Settlement (HO 04 81)" is the modern RCV endorsement; ACV applies if no endorsement is listed.
- Roof endorsements: anything labeled "Roof Surface Settlement," "Cosmetic Roof Damage Exclusion," or "Roof Schedule" can override the dwelling settlement basis specifically for the roof.
If you can't find this in your declarations, your agent is contractually obligated to clarify. Don't accept "you have replacement cost" as the answer — ask for the specific endorsement number applied to the roof.
When ACV is actually fine
A homeowner with a 5-year-old roof on an RCV policy effectively has the same protection either way — the depreciation is small. ACV becomes punitive at year 12+, when the depreciation curve steepens and the gap between ACV and RCV widens past $5,000 on a typical replacement.
For roofs in the late part of the lifespan curve, the math sometimes favors paying out of pocket for the remaining serviceable years and replacing on your own schedule rather than fighting an ACV settlement. See the replacement hub for the full timing-vs-claim decision framework.
The right answer depends on your specific policy, your roof's age, and whether your carrier has been quietly adding endorsements at renewal. Read the declarations page first.
