The amount your insurance pays for a roof replacement depends on more variables than most homeowners realize — and the difference between the best and worst-case payout on the same damage can be $10,000 or more. Here's how to calculate what you'll actually receive before you file a claim.
The 4 Variables That Determine Your Payout
- Your deductible amount and type — flat dollar vs. percentage of home value
- ACV vs. RCV settlement type — depreciated value vs. full replacement cost
- Your roof's age — affects depreciation on ACV policies
- Code upgrade requirements — sometimes covered, sometimes not, depending on policy
Sample Payout Scenarios: Same Roof, Different Policies
Let's use a consistent example: a home with a 14-year-old asphalt shingle roof. Replacement cost today is $13,500. Expected shingle life: 25 years. Remaining useful life: 44%.
| Policy Type | Deductible | Insurance Pays | Out-of-Pocket |
|---|---|---|---|
| RCV, flat $1,000 deductible | $1,000 | $12,500 | $1,000 |
| RCV, flat $2,500 deductible | $2,500 | $11,000 | $2,500 |
| RCV, 1% wind/hail on $350k home | $3,500 | $10,000 | $3,500 |
| RCV, 2% wind/hail on $350k home | $7,000 | $6,500 | $7,000 |
| ACV, flat $1,000 deductible | $1,000 | $4,940* | $8,560 |
| ACV, 1% wind/hail on $350k home | $3,500 | $2,440* | $11,060 |
*ACV calculated at 44% remaining life × $13,500 = $5,940, minus deductible.
How Depreciation Is Calculated
On ACV policies, depreciation is typically calculated based on the shingle type's expected useful life and the roof's current age. Different insurers use slightly different tables, but the general formula is:
ACV = Replacement Cost × (Remaining Life / Expected Total Life)
An architectural shingle (25-year expected life) at year 15 has 10 years remaining out of 25 = 40% remaining life. A $15,000 replacement cost has an ACV of $6,000. After a $2,000 deductible, the insurance payout is $4,000.
Code Upgrade Coverage (Ordinance or Law)
Building codes change. When you replace a roof, you're often required to install materials or details that weren't in the original construction — newer ice-and-water shield coverage, specific drip edge requirements, enhanced underlayment. These code upgrades add $500–$2,500+ to the total replacement cost.
Standard policies do not automatically cover code upgrades. "Ordinance or Law" coverage (also called "Code Upgrade Coverage") is an endorsement that does. If you don't have this endorsement, you pay the code upgrade costs out of pocket regardless of your ACV/RCV status.
Ordinance or Law coverage is typically available for $50–$150/year in additional premium. It's worth having in most markets where codes have evolved since original construction.
The Supplement Opportunity
The adjuster's initial estimate frequently misses legitimate cost items. Common items that can be supplemented (legitimately added to the approved scope after the initial estimate):
- Disposal / haul-away fees: $150–$400
- Overhead and profit (when a general contractor manages the job): 20%+ of material costs
- Specific code-required materials not included in the adjuster's line items
- Accessory components (pipe boots, specific flashing materials) priced below market
- Additional damaged areas or slopes not included in original scope
An experienced roofing contractor who works with insurance claims can identify and submit supplements. This is legitimate, standard practice — not fraud. Supplements can add $500–$3,000+ to the approved amount on a typical residential replacement.
Step-by-Step: Calculate Your Expected Payout
- Get a roofing contractor to estimate the full replacement cost at current market rates
- Find your policy's settlement type (ACV or RCV)
- Find your deductible type (flat dollar or percentage)
- If ACV: calculate remaining life percentage and multiply by replacement cost
- Subtract your deductible from the settlement amount
- Check for Ordinance or Law coverage if code upgrades apply
- Factor in recoverable depreciation collection after work completes (RCV policies)
On an ACV policy with a percentage deductible, the net benefit from filing a claim may be small enough that it's not worth a claim on your loss history. On an RCV policy with a flat deductible, it almost always is. Run the numbers before you file — not after.
