- In the North Carolina files we see, a short first estimate is usually revisited through a supplement: the owner's written request, row by row, that the carrier revise its own numbers. It is not appraisal and not a complaint.
- A lump-sum bid is hard to set against an estimate row by row. Itemized in the estimate's units and laid beside it on a comparison sheet, your contractor's bid shows which rows differ and which evidence each one needs.
- A reinspection is worth what the second visitor can see: your contractor there to show the damage, the attic open, dated moisture readings.
- Read a revised estimate against the version before it, and ask the carrier in writing for the reason behind each row it declined.
- If your estimate came in well below the bid, or a revision left most of the gap in place, send us each version and the bid, and a free review can sort the gap line by line. Our NC residential and commercial property work is generally on contingency — we only get paid from the recovery, not your pocket.
The gap between your insurance estimate and your contractor's bid is usually several disagreements wearing one number, and a request that treats it as one number tends to get one answer back: the estimate stands. Sorted into what an estimate left out, measured smaller or priced lower, the same gap becomes a list of rows the carrier can revise, each with the document behind it.
If you're in Buncombe or Yancey County with a Helene roof the carrier priced as a repair and your contractor bid as a replacement, or in eastern North Carolina with an Isaias wind or tree claim from October 2026 that came in thousands under the bid, you have probably heard the word supplement already. If a supplement is the next step, what goes into it and how it is organized tend to shape what comes back.
This article walks through what a supplement is, how to sort the gap and match each part to its evidence, the reinspection, the revision, what a packet usually carries, and the North Carolina statute its dated log speaks to. We act for owners on these claims, not insurers. Every policy is different, every claim turns on its own facts.
Supplement Insurance Claims: Asking the Carrier to Revise Its Own Estimate
A supplement is a request that the carrier revise its own estimate: it names the rows to add or change, gives the reason for each, and attaches the evidence. It is not appraisal, the policy's process for a disagreement over the amount of loss. Nor is it a complaint to the Department of Insurance, whose Consumer Services Division can take up how a claim was handled but does not set what a claim is worth. A supplement keeps the conversation on the estimate's own lines, where an adjuster can say yes to a row.
Supplements come at two points. Some follow the first estimate, when your contractor's itemized bid shows lines the estimate never priced. Others come during the work, when tear-off turns up soft decking, wet insulation or a second layer of shingles no one could see from the ground. Carriers commonly want hidden damage seen or photographed before it is covered back up, so photograph it in place, with the date and a tape measure in the frame, and tell the carrier in writing what was found before the crew closes it.
Sorting the Gap Between the Estimate and the Contractor's Bid
Start with a comparison sheet: one row for each line on either document, your estimate's quantity, unit and unit price beside the bid's, and a column for the difference. A lump-sum bid doesn't sort easily, so ask the contractor to itemize it in the estimate's units. Each difference then falls into one of three kinds, each with its own evidence: an item the estimate lacks (a photograph and the reason the repair needs it), a quantity it measured smaller (a measured diagram or room dimensions), or a unit price it set lower (local quotes and signed bids). A fourth kind is work the policy generally doesn't pay for. In the files we see, photographs sent against a price, or a quote against a missing item, tend to bring the row back unchanged.
Put numbers on it. Say your estimate totals $16,200 and the bid $23,900, a gap of $7,700. On the comparison sheet, $1,400 is quantity: the estimate measured 26 squares of roofing (a square is 100 square feet) where the contractor's diagram shows 30. A row like that can carry a price difference too, so count the four extra squares at the estimate's own $350 and carry the rest of that row's difference into price. Another $2,600 is lines the estimate never priced, and $2,900 is the bid's higher unit costs on lines both documents carry. The last $800 is a ridge vent the owner chose to add, which a common homeowners form generally doesn't pay for, since its replacement-cost wording is material of like kind and quality and for like use. The request that goes in is for $6,900, each part with its own exhibit.
Getting Ready for the Reinspection
When a supplement adds real money, carriers often send someone back: the original adjuster, a second one, or a roofing inspector or engineer. Policies generally require the damaged property to be shown again when the carrier reasonably asks, so a second visit is part of the process rather than a setback.
On a Helene roof bid as a replacement, the second visit often turns on what can't be seen from a ladder: soft decking, stained sheathing, wet insulation above a ceiling. That is why the attic matters. Before the visit, make sure the carrier has your comparison sheet in writing, ask your contractor to be there to show the reinspector the damage behind each row, and clear the attic hatch. If the mitigation company took moisture readings, have the log ready with the meter, date and location of each; wet framing recorded on day three usually carries more weight than a recollection.
On the day, note what was examined and what was passed over, and take your own pictures of each spot the reinspector records. Afterward, ask in writing for the reinspection notes, the record the revision will be read against.
Reading the Revised Estimate Against the Version Before It
A revised estimate generally carries a new date or version number, and sometimes a total close to the old one. Read it against the version before it, not the bid: the line count, the totals by coverage, then each row on your comparison sheet. A row can be added, left out, changed, or moved, and moves are easy to miss. A fence or detached shed can shift from the dwelling section to other structures, which generally carries its own, smaller limit (10 percent of the dwelling limit on a common form) — a change a nearly unchanged total can hide.
For each row the revision declined, ask the carrier in writing for the reason. "Not visible in the photographs", "not needed for this repair" and "priced elsewhere on the estimate" each point to a different exhibit for the next request.
What a North Carolina Supplement Packet Usually Carries
In the files we see, the supplement requests that move a North Carolina estimate usually carry six pieces, roughly in the order an adjuster reads them.
- A cover letter from the owner, keyed to the estimate's own line numbers. Claim number, date of loss, the estimate version it answers, and a numbered list of each row, the change asked for, the amount and the exhibit, so an adjuster can approve or decline one row at a time.
- The comparison sheet, with anything the policy generally doesn't pay for already taken out. The remaining gap totaled by kind — missing items, quantities, prices — so the carrier sees at the top how much of the request is which.
- One exhibit behind each row, captioned with its line number and date. The photograph, diagram or quote the sort matched to that row. Pictures taken before the tarp went on or the debris was hauled often show what later ones can't.
- The product's identity. A leftover bundle's wrapper, the shingle or siding name on the original invoice, or the manufacturer's marking on a piece removed during temporary repairs. Estimates sometimes price a different product than the one on the house, and the description line shows which.
- The code section or manufacturer's page for any line that exists because of one. On a common homeowners form, the added cost of meeting an ordinance or law is generally paid under its own additional coverage, up to 10 percent of the dwelling limit unless an endorsement raises it, so those rows may come back separately on the revision.
- A dated log of what went out, how, and to whom. Keep a copy of each item sent beside whatever came back, so your file shows which rows the carrier has seen and what it said about each.
Unfair Claim Settlement Practices in North Carolina: Why the Log Matters
North Carolina's claim-settlement law looks at what an insurer does with what it receives — so the last item in the packet, the dated log, matters more than it looks.
North Carolina's Unfair Claim Settlement Practices statute, N.C. Gen. Stat. § 58-63-15, lists the conduct insurers must avoid, including failing to acknowledge and act reasonably promptly upon communications with respect to claims arising under insurance policies. Conduct found to be unfair or deceptive may also support a claim under § 75-1.1, the state's unfair and deceptive trade practices law, which may allow treble damages and attorney's fees. As background, a November 2024 bulletin from the North Carolina Insurance Commissioner addressed claim-handling expectations following that year's storms.
If a packet sits, the log shows when the carrier had each piece, what came back and how long nothing did, which is the record a question about prompt acknowledgment would start from. A log showing a reinspection held and never written up, or a revision that dropped rows with no reason given, reads differently from one showing a slow exchange that kept moving. Keep yours from the first letter.
How Property People Law Approaches North Carolina Supplements and Reinspections
We begin a supplement file by laying each version of the carrier's estimate side by side, to see which rows changed and which never moved. Then we put the contractor's itemized bid against the latest version and sort what remains — missing, measured short, priced low, or outside the policy — checking each row against the photographs, diagram and quotes in your file, and we read any reinspection notes and the reason given on each declined row.
Where the evidence supports a row the carrier hasn't paid, we put that row back in front of the carrier with its evidence, and when revision has run its course we weigh appraisal or suit against what the remaining rows are worth. Our Greensboro office handles these files from the mountains to the coast.
Our NC residential and commercial property work is generally on contingency — we only get paid from the recovery, not your pocket. Past results in other cases don't guarantee outcomes in any new matter, and every claim turns on its own facts.
