Matching Rules, State by State
Nearly every matching argument in this trade traces back to a single sentence in one NAIC model regulation — a document its own history page dates to 1990, amended the year after. States adopted the sentence. Most of the ones below changed something on the way in. The edits are small — a verb here, a noun there — and they are the whole fight.
That is why matching advice does not travel. A roofer in Louisville and a roofer in Des Moines can read the same paragraph in two different rulebooks and get two different scopes out of it. Both are reading correctly.
The sentence everything came from
The NAIC's Unfair Property/Casualty Claims Settlement Practices Model Regulation (Model #902) sets out, at Section 9.A(2), what the text directs under a replacement-cost policy when replaced items do not match in quality, color or size: the insurer replaces "all items in the area" so the result has a "reasonably uniform appearance." The same subsection applies that to interior and exterior losses and says the insured bears no cost over the applicable deductible.
Read that sentence twice, because the state versions are edits of it. Two other things in the same document matter to you. It says its provisions define which practices count as unfair claims practices — a regulator's enforcement tool. And in its purpose section it says nothing in it creates or implies a private cause of action. A rule existing is not the same thing as a homeowner having a remedy, and neither one is the same thing as a check on a specific file.
Where the wording actually lands
| State | Statute, regulation, or neither | What the text turns on | Source |
|---|---|---|---|
| California | Regulation — 10 CCR § 2695.9(a)(2) | Close to the model: "all items in the damaged area," reasonably uniform appearance. Note the added word damaged. | CDI · LII |
| Connecticut | Statute — Conn. Gen. Stat. § 38a-316e | A legislature wrote this one, not a regulator. Keys on replacement items that do not match adjacent items; applies to interior and exterior covered losses; says the insurer is not made a warrantor of the work. | CGA · FindLaw |
| Florida | Statute — Fla. Stat. § 626.9744 | Opens with "unless otherwise provided by the policy." Calls for reasonable repair or replacement of items in adjoining areas, then lists factors the insurer may weigh, including cost and remaining useful life. | FL Senate |
| Iowa | Regulation — Iowa Admin. Code r. 191—15.44(1)"b" | Model sentence rewritten: "as much of the item as is necessary" to reach a reasonably uniform appearance within the same line of sight. Exceptions case by case. | Iowa Legislature |
| Kentucky | Regulation — 806 KAR 12:095 § 9(1)(b), plus a department advisory opinion | Model sentence kept: "all items in the area." The Department of Insurance then published its own reading of what "area" means. | KY LRC · Advisory Opinion 2023-08 |
| Minnesota | Neither — case law | No matching paragraph in the replacement-cost statute or the unfair-practices statute. The Minnesota Supreme Court decided matching in 2014 under the policy's "comparable material and quality" language. | Minn. Stat. 65A.10 · 72A.201 · Cedar Bluff opinion |
| Ohio | Regulation — Ohio Admin. Code 3901-1-54(I)(1)(b) | Two edits, both narrowing: the duty runs to "as much of the item as to result in a reasonably comparable appearance." Comparable, not uniform — and not "all items." | Ohio Admin. Code · LII |
| Tennessee | Regulation — Tenn. Comp. R. & Regs. 0780-01-05-.10(1)(b) | Uniform appearance, but with a tail clause: "according to the applicable policy provisions." | TN Secretary of State |
| Texas | No model-style matching paragraph located | Disputes run on policy wording and court decisions rather than a matching rule. Treat this row as a prompt to verify, not a conclusion — absence is the hardest thing to prove. | — |
Three words decide the fight
The verb
"Replace all items" and "replace as much of the item as" are not the same instruction. The first names a result and lets the scope follow. The second names a measure and leaves someone to decide when enough is enough. Iowa and Ohio use the second form. California and Kentucky use the first.
The noun
What is the unit? The model says "the area" and never defines it. California says "the damaged area." Florida says "adjoining areas." Connecticut says "adjacent items." Iowa says "within the same line of sight." On a hip roof with four planes, each of those words draws a different boundary, and the boundary is the money. This is the single most useful thing to know before you write a word of narrative: your state's noun.
The qualifier
Florida opens with "unless otherwise provided by the policy." Tennessee closes with "according to the applicable policy provisions." Those clauses hand authority back to the contract. Endorsements that put a sublimit on matching are real enough that Kentucky's commissioner took them up directly in the 2023 opinion discussed below. Where the rule defers to the policy, the declarations page and the endorsement list are not paperwork — they are the rule. Read the form before you build an argument the form has already answered.
Two states that look identical and are not
Iowa and Kentucky both adopted the model sentence. Iowa rewrote it around line of sight. Kentucky left it as "all items in the area" — and then the Department of Insurance published Advisory Opinion 2023-08 in October 2023 setting out how it reads that regulation, including what "area" covers and its position on endorsements that limit matching. Trade coverage of the opinion (Insurance Journal) reports the department rejecting a line-of-sight reading, and addressing aging head on: where the same shingle make and model is still made and available, reinstalling it can satisfy the regulation even though the material already on the roof has discolored with age.
Sit with that last point. It reshapes the argument. In a state that reads matching that way, "the old shingles are faded" is a weak opener. Availability is the real question — is the product discontinued, superseded, or simply not obtainable? That is a supply fact, and supply facts are documentable.
A rule existing is not an outcome
Ohio is the clearest warning. The regulation is on the books, and it still does not settle anything by itself. Its paragraph does not say "all items" and does not say "uniform." It asks for a result that is reasonably comparable — a judgment, not a measurement. A judgment word decides nothing until somebody documents the thing being judged.
So: the rule tells you what argument is available. It does not tell you what will happen on this file, with this carrier, on this policy form. Anyone who tells you a matching statute means a full roof is telling you about their marketing, not about your claim.
It is also worth separating categories. Matching is an appearance-and-availability argument grounded in the claims rulebook and the policy. A drip edge argument is a building code argument grounded in what the locally adopted code requires at eaves and rakes — a different mechanism entirely, covered in our drip edge write-up. Do not blend them in one paragraph. A blended argument is easy to wave off as padding, and the code items get dragged down with the matching items.
Checking your own state in about twenty minutes
- Find the claims rulebook, not the marketing page. Search your state's administrative code for its unfair claims settlement practices regulation. The matching paragraph, if there is one, lives in the section on replacement-cost policies.
- Check the legislature too. Connecticut and Florida put theirs in statute. If the regulation search comes up empty, search the insurance title of the state code for matching or uniform appearance.
- Read the three words. Verb, noun, qualifier. Write them down. That is your state's actual rule in three words.
- Check the department's bulletins and advisory opinions page. Kentucky is the example of why. A department's published interpretation of its own regulation can move more than the regulation's text does.
- Note whether your state adopted the model's no-private-action language. It changes who enforces the rule and how.
- Confirm which code year and which amendments apply. States adopt model text and amend it on their own schedule. The version on a blog is not necessarily the version in force.
- Then hand it to a lawyer or a licensed public adjuster before you rely on it. Steps one through six get you oriented. They do not get you an opinion.
Where your job ends
You are the best source of physical fact on the file and the worst possible source of legal conclusion. Keep to the first.
What belongs in your documentation: manufacturer, product line, color name, approximate installation era. Whether the product is discontinued or unavailable, sourced from a named distributor, with the date you asked and what they said, in writing. Photos that show the mismatch from the angle a person actually stands. Which slopes and elevations fall in one line of sight, drawn on a diagram rather than described in prose. That package is a material availability report, and it is the piece the other parties on the claim are not standing on the roof to produce.
What does not belong: a statement that the policy requires anything, a declaration of what the final scope will be, or a promise to the homeowner about payment. Beyond being outside your lane, many states license public adjusting and regulate who may act on a policyholder's behalf in a claim. Check your state's licensing rules before your paperwork starts sounding like an adjuster's. Document the fact, state where the rule is written, and let the licensed parties argue the conclusion. If you want the wider list of items and the refusal language that usually comes back with them, that is in the supplement item list.
The matching rule in your state is one paragraph long. Go read it. It will take less time than the phone call you would otherwise spend arguing about it.
This article describes where certain published statutes and regulations are located and summarizes their wording. It is not legal advice, it is not an interpretation of any insurance policy, and it does not predict how any claim will be decided. Rules change and states amend adopted model text on their own schedule. Verify the current text for your jurisdiction and consult a licensed attorney or public adjuster in your state before relying on any of it.
