Why the Gap Exists
The gap between your claim settlement and your actual repair cost is not a glitch — it is a structural feature of how insurance claims work. Several factors create it, and understanding each one gives you the tools to address it.
The Adjuster's Scope vs. Your Contractor's Estimate
The adjuster writes a "scope of loss" that lists every repair item and assigns a cost using standardized pricing software — typically Xactimate. Your contractor prices the job based on actual local labor costs, material costs, and the specific conditions of your property. These two pricing methods do not always align. Xactimate pricing may lag behind current material costs or use labor rates that do not reflect your local market.
Depreciation Holdback
If you have coverage, your carrier initially pays the — the replacement cost minus depreciation. The withheld depreciation is released after you complete repairs. This means your initial check is intentionally less than the full repair cost. The gap narrows (or closes) after you complete the work and collect the .
ACV Coverage
If you have actual cash value coverage, the depreciation is permanent — it is not recoverable. The older your roof, the larger the depreciation deduction, and the larger the gap between what insurance pays and what repairs actually cost. On a 20-year-old roof, this gap can consume 50-75% of the repair cost.
Missed Damage
Adjusters work on tight schedules and may not identify every damaged component. Missing a few damaged shingles on a back slope, overlooking damaged flashing, or underestimating interior water damage can all contribute to a scope that falls short of actual repair needs.
Anatomy of a Settlement Gap
Contractor's repair estimate: $19,500
Adjuster's scope of loss (RCV): $17,200
Depreciation holdback: -$4,300
Your deductible: -$2,500
Initial check from carrier: $10,400
Gap between check and repair cost: $9,100
Amounts are illustrative. Your settlement components depend on your specific policy, coverage type, and the adjuster's assessment.
The Supplement Process
A supplement is a formal request to your carrier to adjust the scope of loss. It is not an appeal, not a complaint, and not adversarial. Supplements are a routine part of the claims process. Carriers expect them, adjusters process them regularly, and the outcome is often a meaningful increase in the settlement.
Your contractor plays a key role in the supplement process. They prepare a detailed document showing: line items the adjuster missed, items where the adjuster's pricing does not match actual costs, and any additional damage discovered during repairs that was not visible during the initial inspection. This supplement is submitted to your carrier's adjuster for review.
The supplement should be specific and documented. "The repair costs more than you estimated" is not effective. "The adjuster's scope did not include replacement of 12 linear feet of damaged drip edge on the east slope — see attached photos and measurements" is effective. The more precise and documented the request, the faster and more favorable the response.
"If the insurance company already wrote a settlement, that number is final and I can't get it changed."
The initial settlement is a starting point, not a final offer. Supplements are a standard mechanism for adjusting the scope when additional damage is found or when the initial scope did not capture the full repair cost. Most contractors who work regularly with insurance claims submit supplements as a normal part of their process.
Homeowners who accept the initial settlement without reviewing it against their contractor's estimate often leave money on the table — sometimes thousands of dollars.
Understanding Recoverable Depreciation
If your gap is partly caused by depreciation holdback and you have RCV coverage, there is good news: that money is recoverable. After you complete the repairs, you submit your final invoice and proof of completion to your carrier. They then release the withheld depreciation — closing that portion of the gap.
The critical detail is the deadline. Most policies require you to complete repairs and submit documentation within a specified timeframe — typically 180 days to one year from the date of the settlement. If you miss this deadline, the withheld depreciation becomes permanent and you forfeit it. Check your policy for the exact deadline.
Some homeowners use the initial check to fund the start of repairs and then collect the recoverable depreciation to cover the final costs. This works, but it requires careful cash flow management. Your contractor may need a deposit or progress payments before the recoverable depreciation is released. Discuss the payment timeline with your contractor before work begins.
How Recoverable Depreciation Closes the Gap
Initial settlement check: $10,400
You pay contractor deposit and progress payments
Repairs completed — final invoice submitted to carrier
Carrier releases recoverable depreciation: +$4,300
Total received from carrier: $14,700
Your deductible: $2,500
Remaining gap (if supplement was not filed): $2,300
Amounts are illustrative. Deadlines for collecting recoverable depreciation vary by policy. Check yours.
When a Gap Remains After Everything
Sometimes, after supplements and recoverable depreciation, there is still a gap between what your carrier paid and what the repairs actually cost. This can happen for several reasons: your carrier uses pricing that is genuinely below your local market rates, the damage included items not covered by your policy, or your coverage has limitations that cap the payout.
Your options at this point include:
- The appraisal process — most homeowners policies include an appraisal clause. Each side hires an appraiser, the two appraisers select an umpire, and the panel determines the fair value of the loss. This is less expensive and faster than litigation. Your policy explains the process.
- Negotiation through your agent — your agent can sometimes advocate on your behalf with the carrier's claims department. Agents have relationships with underwriters and claims managers that you do not.
- Department of Insurance complaint — if you believe your carrier is not honoring the terms of your policy, your state's Department of Insurance accepts complaints and investigates. This is a regulatory process, not a legal one.
- Legal consultation — for significant gaps, consulting an attorney who specializes in insurance claims can clarify whether your carrier's settlement complies with your policy terms and state law.
Be realistic about the cost of pursuing each option. The appraisal process has costs (your appraiser's fee and a share of the umpire's fee). Legal action has costs. For a gap of $1,000-2,000, the cost of pursuing it may exceed the recovery. For gaps of $5,000 or more, pursuing it often makes financial sense.

ACV Coverage: The Permanent Gap
If you have actual cash value coverage, the settlement gap is fundamentally different — and much harder to close. Under ACV, depreciation is not recoverable. It is permanently deducted from your settlement. The older your roof, the larger the permanent gap.
On a 20-year-old roof with 30-year shingles, the carrier might apply 65% depreciation. On an $18,000 replacement, that is $11,700 deducted. After your $2,500 deductible, the carrier pays $3,800. You pay $14,200 out of pocket. This is the ACV reality, and no supplement or negotiation changes it — it is what your policy provides.
If you are currently on ACV coverage and have not yet had a claim, the most impactful step you can take is to explore whether you can switch to RCV coverage — either with your current carrier or by shopping. If your roof is too old for RCV with any carrier, understanding your ACV exposure helps you plan financially. Knowing the gap in advance is better than discovering it after a storm.
Check Your Understanding
Your carrier's initial settlement check is $8,500, but your contractor estimates the repair at $16,000. You have RCV coverage with $3,200 in recoverable depreciation. What should you do?
First, have your contractor prepare a supplement documenting any line items the adjuster missed or underpriced. Submit the supplement to your carrier. Second, complete the repairs and collect the $3,200 in recoverable depreciation by submitting your final invoice before the policy deadline. Between the supplement and the recoverable depreciation, you may close most or all of the gap. If a gap remains, consider the appraisal process.
Preventing Large Gaps Before They Happen
The best time to address a settlement gap is before it exists. Understanding your coverage and preparing for the claims process reduces the chance of a surprise gap.
- Know whether you have RCV or ACV coverage before you file a claim. Check your declarations page. If you are on ACV, understand the depreciation impact before the adjuster arrives.
- Have your contractor present during the adjuster's inspection when possible. They can point out damage the adjuster might miss and discuss scope in real time.
- Document everything yourself — do not rely solely on the adjuster's photos and notes. Your independent documentation supports supplements if needed.
- Ask your contractor if they handle supplements as part of their service. Many experienced insurance restoration contractors include supplement preparation in their process.
