Actual cash value vs. replacement cost on a commercial roof
Short answer
Actual cash value pays what it costs to repair or replace the roof minus depreciation, the value the roof has lost to age and wear. Replacement cost pays that cost with no deduction. On a roof claim, the difference between the two is the depreciation, and it grows as the roof ages. Under the standard ISO commercial form, replacement cost is paid only after the roof is actually repaired or replaced, so a hail claim is usually paid at actual cash value first, with the depreciation held back until the work is done.1

How the two valuations work
Replacement cost pays to repair or replace damaged property at today's prices, with nothing taken off for age. Actual cash value starts from the same cost and subtracts depreciation. Which one applies is set by the policy, and one policy can value some buildings or items one way and the rest the other way.
In the 2012 ISO Building and Personal Property Coverage Form (CP 00 10), actual cash value is the default. Replacement cost replaces it only where the declarations show the Replacement Cost optional coverage, item by item.1
The ISO form does not define actual cash value. Where a policy leaves it undefined, it is usually measured one of three ways: cost to repair or replace minus depreciation, fair market value, or the broad evidence rule, which weighs all relevant evidence of value.1,2
One ISO endorsement changes the valuation for roofs. Under Paragraph A of Limitations on Coverage for Roof Surfacing (CP 10 36), roof surfacing on the buildings listed in its schedule is valued at actual cash value, even where replacement cost would otherwise apply. Roof surfacing there means shingles, tiles, cladding, metal or synthetic sheeting or similar materials covering the roof, the materials that secure them, the moisture protection applied to or under them, and flashing.3
How roof depreciation is figured
Depreciation on a roof usually rests on three things: its condition at the time of loss, what a new roof would cost and how long that kind of roof normally lasts. The simplest method divides the roof's age by its expected life. What gets subtracted is physical wear and tear, though some courts have also let insurers deduct economic obsolescence.
For example, a 5-year-old roof with a 20-year expected life is depreciated 25%, so $5,000 comes off $20,000 of roof damage.4
Worked example: one hail claim, two valuations
The numbers below are made up, in round figures. The steps are the ones a commercial roof claim follows: subtract depreciation to reach actual cash value, subtract the deductible, and pay the held-back depreciation after repair.
| Step | Actual cash value policy | Replacement cost policy |
|---|---|---|
| Cost to replace the roof (estimate) | $400,000 | $400,000 |
| Depreciation: 10 years into a 25-year expected life (40%) | -$160,000 | -$160,000 (held back) |
| Actual cash value | $240,000 | $240,000 |
| Deductible (flat, for this example) | -$50,000 | -$50,000 |
| First payment | $190,000 | $190,000 |
| Held-back depreciation, paid after repair | None | $160,000 |
| Total paid | $190,000 | $350,000 |
On a replacement cost basis, the ISO form pays the least of three amounts: the limit of insurance, the cost to replace with property of comparable material and quality used for the same purpose, or the amount actually spent. In the example, if the new roof costs $380,000, the settlement becomes $380,000 minus the $50,000 deductible, or $330,000, and the holdback paid after repair is $140,000.1
Worked example: the gap under an actual cash value roof endorsement
Under CP 10 36 Paragraph A, scheduled roof surfacing is valued at actual cash value even under a replacement cost policy, so its depreciation is never paid; that is the gap. Cost, age and the building's limit are made-up round numbers, and the limit is assumed to meet any coinsurance requirement.3,1,5
| Step | Example | Basis |
|---|---|---|
| Expected life | 20 years | Fannie Mae multifamily useful life table (built-up, EPDM, TPO) |
| Roof age at the loss | 12 years | Example |
| Depreciation | 12 / 20 = 60% | Age over expected life |
| Roof surfacing replacement cost | $600,000 | Example |
| Actual cash value | $240,000 | $600,000 minus 60% |
| Windstorm or hail deductible | $200,000 | 2% of the building's $10,000,000 limit (CP 03 21 allows 1%, 2% or 5%) |
| Paid with the endorsement | $40,000 | $240,000 minus $200,000 |
| Paid at replacement cost, no endorsement | $400,000 | $600,000 minus $200,000, after replacement |
| Gap | $360,000 | The depreciation |
Because CP 03 21 bases the deductible on the building's limit, the same $200,000 is 83% of the actual cash value but 33% of the replacement cost. Fannie Mae's lives are standardized averages for multifamily condition assessments, not a replacement for an assessor's judgment of effective age.5,6
How held-back depreciation is released
Recoverable depreciation is the difference between replacement cost and actual cash value: the part held back until the work is done. It is also called withheld depreciation or a replacement cost holdback. To release it, expect to show the contractor's bill for the finished job, documentation of the repairs, a record of repair costs and proof the deductible was paid.
The ISO form's Replacement Cost optional coverage sets these terms:1
- No payment on a replacement cost basis until the property is actually repaired or replaced.1
- The repair or replacement must be made as soon as reasonably possible after the loss.1
- The insured may settle first at actual cash value and still claim the replacement cost difference by notifying the insurer within 180 days after the loss.1
- Replacement cost excludes added costs to meet any ordinance or law.1
- A building rebuilt at a new premises is paid only what rebuilding at the original premises would have cost.1
Time limits to claim held-back depreciation
| Policy | Time limit |
|---|---|
| ISO CP 00 10 commercial form | Repair as soon as reasonably possible; if first settled at actual cash value, notice of intent to claim replacement cost within 180 days after the loss |
| TWIA policies (Texas coast) | Repair documentation within 545 days of receiving the first claim payment, when repairs exceed that payment |
Texas rules
In Texas, an insurer that issues replacement cost coverage may refuse to pay withheld recoverable depreciation or a replacement cost holdback until it receives reasonable proof the policyholder paid the deductible (Texas Insurance Code Section 707.004). The statute names a canceled check, money order receipt, credit card statement, or an installment or financing contract that requires full payment of the deductible over time. Section 707.002 requires anyone insured under a property policy to pay any deductible on a first-party claim.7
On the Texas coast, TWIA pays a replacement cost claim in at least two parts: the actual cash value first, then the recoverable depreciation after repairs or replacement are done.4,8
TWIA also writes commercial policies. Its replacement cost endorsement for them is TWIA-164; without it, TWIA processes claims at actual cash value. TWIA treats a policy insured to 80% or more of replacement cost, shown as the coinsurance percentage on the declarations, as replacement cost coverage.4
Questions for the broker
Ask the broker:
- Do the declarations show replacement cost or actual cash value for each building?
- Does CP 10 36 Paragraph A, or a similar endorsement, value roof surfacing at actual cash value, and on which buildings?3
- What is the deadline to claim held-back depreciation, and does it run from the date of loss or from the first payment?
- What proof of repair and of deductible payment does the insurer require before it pays the holdback?

Questions
- What's the difference between ACV and replacement cost on a commercial roof, and how does it affect a hail claim?
- Actual cash value takes depreciation, the value the roof has lost to age and wear, off the cost to replace it; replacement cost does not. Under replacement cost, a claim is usually paid at actual cash value first, with the depreciation paid after the roof is repaired or replaced. Under actual cash value, the depreciation is never paid.
- How do I recover depreciation holdback on a commercial property insurance claim?
- Under the ISO commercial form, replacement cost is paid once the property is actually repaired or replaced, as soon as reasonably possible. If the claim was first settled at actual cash value, the form requires notice of intent to claim replacement cost within 180 days after the loss. In Texas, the insurer may also require reasonable proof the deductible was paid.1,7
- How big is the gap between replacement cost and what an actual-cash-value roof endorsement would pay on our building?
- When actual cash value exceeds the deductible, the gap is the roof surfacing's depreciation. In a made-up example (Fannie Mae's 20-year TPO life, a 12-year-old roof, 60% depreciated), $600,000 of roof surfacing with a $200,000 (2%) hail deductible pays $40,000 with the endorsement and $400,000 at replacement cost: a $360,000 gap.3,1,6,4,5
- How is depreciation calculated on a roof?
- It usually rests on the roof's condition at the time of loss, the cost of a new one and how long it would normally last. In a simple example, a 5-year-old roof with a 20-year expected life is depreciated 25%.4
- How long do I have to recover depreciation in Texas?
- It depends on the policy. TWIA requires repair documentation within 545 days of the first claim payment when repairs exceed that payment. The ISO commercial form sets a 180-day notice for claiming replacement cost after an actual cash value settlement.1,4
- Can the insurer require proof that the deductible was paid?
- In Texas, yes. Texas Insurance Code Section 707.004 lets an insurer refuse to pay withheld recoverable depreciation or a replacement cost holdback until it receives reasonable proof the deductible was paid.7
