ACV, RCV, and the second check: where a supplement actually lands
The call usually comes a week after the supplement was approved. The contractor is looking at the homeowner's first check, comparing it to the supplement amount, and neither number matches the other. The conclusion feels obvious: the carrier approved the supplement and then didn't pay it. Most of the time, that conclusion is wrong — not because the carrier paid, but because the contractor is looking at the wrong check.
To see why, you have to understand where a supplement lands in the payment mechanics of a claim. Not the negotiation, not the approval — the accounting. This is the part of the process that generates more confused phone calls than any other, and it runs on three terms: RCV, ACV, and recoverable depreciation.
The three terms, defined mechanically
RCV — replacement cost value. This is the carrier's estimate of what it costs to repair or replace the damaged property with materials of like kind and quality, at current prices. On a roof claim, it is the total of every line item in the estimate: shingles, underlayment, flashing, tear-off, disposal, and whatever else the scope includes. RCV is the ceiling of the conversation. Every other number on the claim is derived from it.
Depreciation. The carrier reduces the RCV to account for the age and condition of what was damaged. A fifteen-year-old roof has consumed part of its useful life, and the depreciation line reflects that. How the carrier calculates it — the schedule, the assumed lifespan, whether labor is depreciated along with materials — varies by carrier and by state. This is one of the places where policies genuinely differ, and it is worth reading the estimate rather than assuming.
ACV — actual cash value. ACV is what remains after depreciation comes out: RCV minus depreciation. It represents the value of the roof as it stood the day before the storm, not the cost of the new one going on.
The relationship is a subtraction, not three independent numbers. If you know two of them, you know the third. That single fact resolves most of the confusion on payment day.
Why the first check is smaller than the estimate
On a replacement cost policy, the common payment sequence goes like this: the carrier issues a first check at ACV, minus the deductible. The rest of the RCV — the depreciation — is held back until the work is actually completed. Once the contractor finishes and the completion is documented, the policyholder requests the held-back amount, and the carrier issues a second check. That held-back portion is what the industry calls recoverable depreciation.
A simplified example, with round numbers chosen only to show the arithmetic: an estimate carries an RCV of $20,000. The carrier applies $6,000 in depreciation, which puts ACV at $14,000. The policyholder has a $2,000 deductible. The first check is $12,000 — ACV minus deductible. The remaining $6,000 sits as recoverable depreciation, payable after completion. Nobody has been shorted. The full $20,000 is still in play; it is just arriving in two pieces, with the deductible as the policyholder's share.
Two caveats, both of the “policies differ” kind. First, not every policy pays on a replacement cost basis; some settle at ACV only, and on those there is no second check to wait for. Second, some policies write part or all of the depreciation as non-recoverable, in which case that portion does not come back even after completion. Which situation you are in is a question the declarations page and the estimate answer — not a question a contractor should guess at from the size of the first check.
What happens when a supplement is approved
Now add a supplement to this machine. Say the original estimate missed items — drip edge, steep-slope labor, decking replacement discovered at tear-off. The contractor documents the missing scope and submits it. The desk adjuster reviews it and approves some or all of the items.
Here is the mechanical part that matters: an approved supplement does not generate a standalone payment for the supplement amount. It gets absorbed into a revised estimate. The carrier reissues the estimate with the new line items included, and every derived number moves. The RCV goes up. Depreciation is recalculated on the new items — and note that some supplement items, particularly labor-driven ones, may depreciate differently than materials. The ACV shifts accordingly, and the recoverable depreciation balance changes too.
This is not a quirk of one company. Citizens' published claims-handling practices describe exactly this flow for contractor-submitted estimates: the adjuster prepares a comparative line-item estimate against the contractor's document, and accepted amounts are entered into the carrier's final estimate. The supplement, once accepted, stops existing as a separate document. It becomes rows in the carrier's revised estimate, subject to the same ACV/RCV split as everything else.
Practically, that means the money from an approved supplement arrives in one of two ways. If the ACV of the revised estimate now exceeds what was already paid, the carrier owes an additional ACV payment on the difference. But a large share of a typical supplement — especially one approved after the roof is already on — lands on the depreciation side and shows up in the second check, folded into the recoverable depreciation payout. The supplement amount and the check amounts will not match line for line, because the supplement was never going to be paid as a lump; it was going to be metabolized into the estimate.
The mistake that generates the angry phone call
The most common error is comparing the approved supplement total against the first check and concluding the supplement went unpaid. The first check was cut from the original estimate's ACV, often before the supplement was even submitted. Of course it doesn't include the supplement. The question is not “does the first check cover my supplement” — it is “does the revised estimate include my line items, and what does the payment ledger say has been paid against it so far.”
A close cousin of this mistake: treating the recoverable depreciation check as “extra” money and forgetting it was part of the RCV all along. Contractors who price a job off the first check alone and then treat the second check as a windfall are misreading the same subtraction from the other direction. The RCV is the number the job was scoped against; the checks are just installments of it.
A third version shows up on the carrier side of the table. Some carriers — TWIA says this on its own claims pages — specifically ask for line-item estimates that break down and show labor and material costs, rather than a single lump-sum figure, and state that they will review the submitted estimate against their own. A supplement submitted as one bottom-line number gives the reviewer nothing to enter into a revised estimate. The revision process works row by row; a document without rows cannot feed it. This is the same reason a complete, itemized supplement list matters more than a persuasive total.
Reading the paperwork instead of the check
Every question in this article is answerable from two documents: the current revised estimate and the payment history. The estimate shows RCV, depreciation, and ACV — usually summarized on the first or last page, with the line items in between. The payment history shows what has actually been issued and against which version of the estimate.
When a supplement decision comes back, the useful move is not to look at a check. It is to pull the revised estimate and walk it: Are the supplement items present as line items? At what quantities and prices? How was depreciation applied to them? What is the new RCV, and how much of it has been paid to date? Photographs tied to each supplement item — the kind of documentation that survives a desk review — make this walk faster, because the adjuster who accepted the items had something concrete to enter.
Checklist before the file closes
Before treating a claim as finished, it is worth running a short mechanical audit:
1. Obtain the final revised estimate. Not the original, not the supplement submission — the carrier's latest issued version. Confirm the approved supplement items actually appear in it as line items. Approval in an email that never made it into a revised estimate is a loose end, not a payment.
2. Reconcile RCV against payments. Add up every check issued on the dwelling coverage and compare against the revised RCV minus the deductible. The gap should equal the outstanding recoverable depreciation. If it doesn't, something is either unpaid or miscategorized, and it is far easier to raise that while the file is open.
3. Confirm the depreciation is actually recoverable. Check whether the estimate flags any portion as non-recoverable. Policies differ here, and the distinction changes what the second check will contain.
4. Trigger the depreciation release. Recoverable depreciation is typically paid on request after completion, not automatically. Most carriers want notice that the work is done, and many want a completion certificate or final invoice. Know who is responsible for sending it — on some carriers, including TWIA, documents on the claim must come from the policyholder, so the contractor's role is to prepare the paperwork and make sure the homeowner actually submits it.
5. Account for items like O&P and code upgrades separately. Overhead and profit and code-required items each have their own payment quirks — O&P in particular is sometimes held and released on its own logic. Verify where each landed in the revised estimate rather than assuming it rode along with the depreciation check.
6. Close the loop with the homeowner. The policyholder receives the checks and often does not know the two-check structure exists. Five minutes explaining ACV, the deductible, and the depreciation release prevents the “the insurance company shorted us” conversation three weeks later — a conversation that otherwise arrives at the contractor's phone.
The supplement's real destination
A supplement, done right, is not a bill you send and get paid on. It is a set of line items you are asking the carrier to adopt into its own estimate. Once adopted, those items obey the estimate's mechanics: they raise the RCV, they get depreciated, and they pay out across the ACV and recoverable-depreciation split like every other line. Understanding that path is the difference between reading a payment correctly and burning an afternoon disputing a check that was never supposed to contain the number you were looking for.
This is written for contractors preparing their own supplements. It is not legal advice and it is not a reading of anyone's policy. Verify the adopted code edition and your carrier's submission channel for the property in question.
