Has your insurer agreed that the storm damaged your roof, then sent a settlement that falls far short of every contractor estimate on your kitchen table? If so, you may not need a denial appeal, a lawsuit, or another tense call with the adjuster. You may need a clause that most homeowners never read.
Most standard homeowners policies contain an appraisal provision. It is a process built into the contract for settling disagreements over the dollar amount of a covered loss. Below, we explain when appraisal applies, how the appraisers and umpire are chosen, what it costs, and how it differs from a supplement or an appeal after a denial.
What The Appraisal Clause Actually Says
The wording varies by carrier. Still, many policies follow the Insurance Services Office (ISO) HO 00 03 homeowners form or something close to it, and here is how that standard wording works, condition by condition:
- The trigger. If you and the insurer cannot agree on the amount of loss, either side may demand appraisal in writing.
- Appraiser selection. Each party chooses a competent and impartial appraiser within 20 days of receiving the other side's written request.
- Umpire selection. The two appraisers choose an umpire. If they cannot agree on one within 15 days, either party may ask a judge of a court of record in the state where the home is located to appoint one.
- The award. Each appraiser sets the amount of loss separately. If they agree in writing, that figure becomes the amount of loss; if they do not, they submit their differences to the umpire, and a decision agreed to by any two of the three sets the amount.
- The cost split. Each party pays its own appraiser and splits the umpire's fee and other appraisal expenses equally.
Keep in mind that your own policy may change any of these terms. Some carriers have rewritten the clause, some state endorsements change the timelines, and some policies leave appraisal out or make it optional, so the conditions section of your own policy is what controls.
When Appraisal Applies — And When It Does Not
The most important rule is that appraisal settles disputes over the amount of loss, not disputes over coverage. If the insurer agrees that hail damaged your roof but values the repair at a fraction of your estimate, you have an amount dispute. If the insurer says the damage is wear and tear and it owes nothing, you have a coverage dispute.
Amount disputes that commonly fit appraisal include but are not limited to:
- Repair versus replacement scope. The adjuster paid to replace a few slopes, while your contractor documented damage on every slope.
- Pricing. Both sides agree on the scope, but the insurer's estimating software prices labor and materials below what local contractors actually charge.
- Missing components. The estimate leaves out underlayment, drip edge, ridge vent, flashing, or charges for steep or tall roofs.
- Matching. The insurer priced a partial repair even though the existing shingle is discontinued. We cover that situation in our guide to roof matching disputes.
Coverage questions, on the other hand, generally fall outside what appraisers are allowed to decide. These include whether the policy covers cosmetic hail damage, whether a wear-and-tear or maintenance exclusion applies, whether you reported the claim late, and whether you bought ordinance or law coverage.
That said, the line blurs when the question is what caused the damage. Courts in different states have split on whether appraisers can decide causation — for instance, which shingles were bruised by hail and which were aged by sun — so this is a point where a licensed professional in your state is worth consulting before you send a demand.
How To Tell Whether You Have An Amount Dispute
Before demanding appraisal, put the two numbers side by side and find exactly where they differ. Our guide to comparing roof estimates explains how to line up two estimates item by item rather than by the bottom line.
Once you have that comparison, a few questions will tell you whether appraisal is the right tool:
- Has the insurer confirmed in writing that the loss is covered?
- Is the gap driven by quantities, unit prices, or missing line items rather than by a refusal to pay?
- Have you already sent supporting documentation, such as photos, measurements, and a contractor's itemized estimate?
- Is the difference large enough to justify paying your own appraiser and half of an umpire?
If the answer to each is yes, appraisal is likely available. If the insurer has not confirmed coverage, or you have not yet sent your documentation, the claim may not be ready for appraisal, and our guide on how to document storm damage for an insurance claim is a better first step.
How The Appraisal Process Works, Step By Step
Although each carrier's process differs slightly, most roof claim appraisals follow the same general order. Here is a list of the steps:
- Written demand. One party sends a written appraisal demand that cites the policy's appraisal condition, the claim number, and the amount in dispute. Keep a copy, and send it by a method you can track.
- Appraiser selection. Each side names its appraiser within the policy window, which is 20 days under the standard ISO wording.
- Umpire selection. The two appraisers try to agree on a neutral umpire, typically an experienced estimator, engineer, adjuster, or attorney. If they cannot agree within the policy window, either side may ask a court to appoint one.
- Inspection and estimates. Each appraiser inspects the roof, reviews the claim file, and prepares their own valuation of the loss.
- Negotiation between appraisers. The two appraisers compare figures and try to agree. Many appraisals end at this stage without the umpire ever getting involved.
- Umpire decision. If the appraisers still disagree, they send only the disputed items to the umpire. An award signed by any two of the three becomes the amount of loss.
- Payment. The insurer pays the award under the terms of your policy, minus your deductible and anything it has already paid.
Keep in mind that the award does not override the rest of your policy. If your coverage pays actual cash value first and recoverable depreciation later, that holdback still applies to the appraised amount.
How long appraisal takes varies widely. A simple appraisal may finish within weeks, while one that needs a court-appointed umpire or a second inspection can stretch for months.
Choosing Your Appraiser
The standard clause requires an appraiser who is competent and impartial. In practice, competence means someone who understands roofing systems and the estimating software insurers use — being able to defend a line item for ice-and-water shield, starter strip, or a steep-roof charge matters more than a polished resume.
Impartiality is where many homeowners stumble. Even though you choose your appraiser, most policies and many state courts expect that person to value the loss honestly rather than argue your side, which is why the roofer who wrote your estimate and hopes to win the job is usually a poor choice.
Before you hire anyone, consider asking each candidate:
- How many residential roof appraisals have you handled, and in which states?
- How do you charge — by the hour, a flat fee, or a percentage of the award?
- Has anyone ever challenged your impartiality or had you disqualified?
- Do you have any financial relationship with my contractor or public adjuster?
Be aware that some states restrict appraisers from charging a contingency fee, because a fee tied to the size of the award can compromise impartiality. Ask about this directly, and get the fee agreement in writing before the appraiser starts work.
What Appraisal Costs
Appraisal is not free, so look closely at the costs before you send a demand. Under the standard wording, you pay your own appraiser in full and split the umpire's fee and other shared expenses with the insurer.
Appraiser fees usually take one of three forms:
- Hourly. You pay for inspection, estimating, and negotiation time. This is predictable on simple roofs and open-ended on contested ones.
- Flat fee. You pay a set price for the job, sometimes with an extra charge if the umpire is needed.
- Percentage of the award. You pay a share of the final amount, or of the increase over the insurer's offer, where state law allows it.
Fees vary too much by market and by claim to quote a single figure here, so ask at least two appraisers for written quotes. As a general rule, appraisal tends to make financial sense only when the gap between your number and the insurer's is several times larger than what you expect your share of the process to cost.
Appraisal Versus A Supplement Versus An Appeal
Homeowners often treat these three terms as interchangeable. In fact, each is a different tool for a different problem, and choosing the wrong one wastes time and, in the case of appraisal, money.
The Supplement
A supplement is a request to add items to an open claim that the original estimate missed or that only became visible once the old roof came off. Typical examples include rotted decking, extra layers of old shingles, code-required underlayment, or flashing that could not be inspected until removal.
Supplements are part of the normal claim process and are usually submitted by your contractor with photos and measurements. They cost nothing beyond the work of documenting them, and most disagreements over price should go through at least one round of supplements before anyone mentions appraisal.
The Appeal After A Denial
When the insurer denies a roof claim outright, the dispute is about coverage, and appraisal generally will not help. The usual options are a written request for reconsideration with new evidence, a reinspection, a complaint to your state department of insurance, or a consultation with an attorney. We walk through each of these in our guide to what happens when a roof claim is denied.
Appraisal
Appraisal sits between those two. It is the right tool when the insurer has accepted coverage, the supplement process has run its course, and the two sides still cannot agree on price or scope.
To summarize the three:
- Supplement. The claim is still open, items are missing or newly found, and there is no added cost.
- Appraisal. The claim is covered but the amount is in dispute, and each side pays its own appraiser and splits the umpire.
- Appeal after denial. Coverage was refused, the focus is on policy language and evidence, and the dispute may go on to a regulator or court.
Appraisal, Public Adjusters, And Attorneys
Appraisal is one of several ways to get help with an underpaid claim, and it does not replace the others. A licensed public adjuster works for you through the whole claim and typically charges a percentage of the settlement, while an appraiser is hired only for the appraisal itself.
Some homeowners hire a public adjuster who then recommends appraisal, while others go straight to appraisal when the price gap is narrow. If the insurer is disputing coverage, accusing you of misrepresentation, or delaying payment without explanation, an attorney licensed in your state is usually the better first call.
Deadlines And Pitfalls To Watch
Appraisal does not stop the other clocks in your policy, and several timing issues can trip homeowners up. Keep the following in mind:
- Deadlines to sue. Most policies require any lawsuit to be filed within a set period after the loss, and depending on your state, appraisal may not pause that clock. Our guide on how long you have to file a roof insurance claim explains the main deadlines.
- Depreciation deadlines. Replacement-cost policies often require you to finish repairs within a set period to collect the depreciation the insurer held back. Ask whether that deadline is extended while appraisal is pending.
- Waiving appraisal. If you keep negotiating long after reaching a stalemate, or file a lawsuit first, the insurer may argue that you gave up your right to appraisal.
- Protecting the roof in the meantime. You still have to protect the property from further damage during appraisal, so tarp the roof and keep your receipts.
- Contractor pressure. Be wary of an out-of-town crew that pushes you to sign an assignment of benefits or an appraisal agreement on the spot. These are the same warning signs described in our guide to storm chaser roofers.
Getting your insurer's answers to these questions in writing before you invoke appraisal can prevent a costly mistake later.
Making The Decision
All of the above adds up to a fairly simple test. If your insurer has accepted that the roof damage is covered, your documentation is complete, supplements have not closed the gap, and the difference comfortably exceeds the cost of the process, appraisal is often faster and cheaper than a lawsuit.
On the other hand, if the insurer has denied coverage, the gap is small, or the dispute turns on legal questions such as exclusions or late notice, a different path will likely serve you better. Either way, read the conditions section of your policy before you act — that document, not a general guide, sets the rules for your claim.
