A roof claim supplement is a request for more money on a claim that is already open. It usually comes up when the first payment is lower than the roofer's estimate, or when the crew finds damage the adjuster could not see from the roof surface, such as rotted decking. Nothing in a standard homeowners claim stops you from asking. The NAIC, the association of state insurance regulators, says an insurance claim stays open until the insurer has made all the payments you are entitled to under your policy, and Triple-I, the insurance industry's information group, says that if you find other damage you can reopen the claim and file for an additional amount. "Supplement" is trade language, so you will hear it from roofers and adjusters but not much in regulators' guides. This page is general information, not legal or insurance advice, and your policy and state rules decide what you can recover.
The three reasons a roof payment goes up
| Reason | What it means | Who usually starts it |
|---|---|---|
| Recoverable depreciation | The first check held back part of the cost, and the insurer pays it after the work is done | You, with proof of the completed repair |
| A disagreement over the scope or price | The insurer's list of work or its prices differ from your contractor's | You, with a written estimate |
| Newly found damage | Work uncovered damage that no one could see at the inspection | You or your contractor, with photographs, before the damaged part is covered up |
Only the first is automatic once you finish the roof. The other two are requests, and the insurer decides.
Recoverable depreciation: money held back, not lost
If your policy pays replacement cost, the insurer may first pay only the actual cash value, the cost of the roof minus depreciation. The NAIC's post-disaster claims guide explains the next step: when you show that the property has been repaired or replaced, the insurer pays the difference, up to the replacement cost. The guide calls the difference "recoverable depreciation", and says it is the gap between an item's replacement cost and its actual cash value.
The NAIC also says the insurer usually figures depreciation from the condition of the property when it was damaged, what a new one costs and how long it normally lasts. For a roof, its guide says an actual cash value policy on a 20-year-old roof destroyed by a covered cause may pay as little as 20 percent of the cost to replace it, because a roof's useful life is usually about 25 years. A replacement cost policy would pay the full cost. Our guide to your roof's age and your insurance shows how age changes the numbers.
The clock
There is usually a time limit for collecting that held-back money, the NAIC says. It ranges from 6 months to up to one year, depending on your state's law and your policy. After a very large disaster, insurers know rebuilding takes longer and give more time if you ask, and your state insurance department may require them to. Ask your adjuster for the date in writing. Do not let the roof sit unfinished while the clock runs.
See the math
The NAIC's model claims regulation says that when a policy settles on actual cash value, the insurer determines it as the replacement cost at the time of loss less depreciation, and that on your request it must provide a copy of the claim file worksheets detailing any deductions for depreciation. That is the model; check whether your state requires the same. If the depreciation looks wrong, the worksheet is where to see how it was figured.
When the estimate and the scope differ
The NAIC says differences between estimates are common. Its guide says the aim is to agree a "scope of loss", a detailed list of the quantities of materials, labor, profit and overhead, building code compliance and every item needed to repair or rebuild. Once you submit all the information the insurer needs, including written contractor estimates, the adjuster calculates the total.
So the useful supplement request is specific. It lists the line, the quantity and the price in dispute, and why. For example: the insurer's list prices the shingles on one slope, while your contractor's written estimate also lists the flashing on that slope as a separate line. Our guide to comparing roofing estimates shows how to read the lines of an estimate so you can match them against the insurer's.
The model regulation has two lines that bear on this. When a replacement cost loss requires repair or replacement of a part, consequential physical damage from making the repair that the policy does not exclude is to be included in the loss, and you do not pay for betterment or any cost except the deductible. When replaced items do not match in quality, color or size, the insurer is to replace all items in the area so the result conforms to a reasonably uniform appearance. These are model wording, not law everywhere, and a policy can limit them, so read ours on matching and discontinued shingles before you rely on either.
If the two sides still differ on the amount, the NAIC says appraisal is one route, and our guide to a denied claim explains how it works.
Damage found mid-job
Hidden damage is the classic supplement. Decking that is soft under old shingles or a failed flashing detail cannot always be seen until the old roof is off. Triple-I says that if you find other damage you can reopen the claim and file for an additional amount, and that most policies require a claim within one year of the loss. Check your own deadline.
Two habits help. Ask your roofer to photograph the problem with the date before it is covered, and to write down what was found and what it costs to fix. Then tell the insurer promptly, in writing, before the work goes on, not after. The insurer may want to look first, and nothing here says it will pay for work done before it was told. The adjuster's role stays the same: the NAIC says the insurer will typically send a company or independent adjuster to assess damage. See our guide to the roof replacement process for when a crew can uncover these problems.
The mortgage company on the check
If you have a mortgage, the NAIC says your lender required you to add it as an additional insured on your homeowners policy, so the insurer is obliged to include it on the check for major repairs. You then work with the lender to release the money for repairs. Triple-I adds that some lenders hold the money in escrow and pay the contractor as the work is completed, and may inspect the finished job first. Expect extra days on each payment.
If you have problems with your lender, the NAIC points to your state's bank and mortgage regulator or attorney general, and to a federal complaint site for lenders, usa.gov/complaints-lender. Your insurer should not make an additional living expense check payable to the lender, Triple-I says; that check is for you.
Checks that say "final"
Read the wording on a payment. Under the NAIC's model regulation, an insurer should not indicate on a check, draft or accompanying letter that a payment is final, or a release of any claim, unless the policy limit has been paid or you have agreed to a compromise settlement. It also says an insurer should not issue a partial-settlement check that carries language purporting to release the insurer from total liability. Do not sign a release because a payment arrived: ask what remains open, and in writing. Where the amount is determined and not in dispute, the model says the insurer should pay within 30 days of affirming liability.
Do not hand off your claim
After a storm some contractors offer to "handle" your claim. The NAIC warns about assignment of benefits, where a contractor acts for you with your insurer and collects the payments without you, and says signing one is not required to get repairs done. The FTC says never to sign your insurance check over to a contractor. Our guide to roofing scams and storm chasers lists the red flags. A supplement is your claim, your policy and your signature. A contractor can supply documents, and you decide what to send.
A public adjuster is a different thing: someone you hire, who has no ties to the insurer, and who estimates damage and negotiates for a fee. Triple-I says the fee can be as much as 15 percent of the settlement, and the NAIC says some states bar public adjusters from negotiating. Read the contract.
Frequently asked questions
Can I get more than the first estimate says?
Sometimes. Triple-I says you can reopen a claim to file for more if you find other damage, and the NAIC says differences in estimates are common. The insurer decides, based on your policy, so give written estimates and photographs.
When do I get the depreciation back?
On a replacement cost policy, after you show the roof has been repaired or replaced, the NAIC says. There is usually a time limit of 6 months to a year, set by your state's law and your policy. Ask for the date.
Why is my mortgage company on the check?
The NAIC says your lender is an additional insured on your policy, so the insurer includes it on the check for major repairs. You will need the lender to release the money.
Can my roofer file a supplement for me?
A roofer can supply estimates and photographs. The claim stays yours, and the FTC says never to sign your insurance check over to a contractor, and the NAIC says an assignment of benefits is not required to get repairs done.
Is a supplement the same as a new claim?
No. It adds to an open claim. A separate new storm is a separate claim, and policies have their own deductibles and time limits, so check yours.
