Most homeowners arrive at this fight using a word that is not in their policy, and it costs them the first exchange. Keeping the three terms apart is most of the work. This is the analysis behind our Atlas Chalet and discontinued-materials page, in full.
What your policy actually says
The standard homeowners form sets the replacement-cost measure in one line: “The replacement cost of that part of the building damaged with material of like kind and quality and for like use.” That is ISO form HO 00 03 10 00, Section I – Conditions, Loss Settlement. Two tests, joined by the word “and.” Kind and quality is the material test. Like use is the function test. A replacement that only performs the same job has satisfied half of that sentence. Carriers point out, correctly, that the paragraph is written as a ceiling on payment rather than a shopping list. The ceiling is still measured in those words. And the same form’s “Our Option” condition binds an insurer that elects to do the repair itself to “material or property of like kind and quality,” so managing the repair does not lower the standard of it.
Search that form for “functionally equivalent” and it is not there. Search it for “matching” and that is not there either. Read your own form, because carriers write proprietary wording and edition dates differ. Commercial policies word it differently again, promising property “of comparable material and quality” and “used for the same purpose,” with “like kind and quality” appearing further down among the insurer’s loss payment options. Courts decline to treat the two as synonyms: when an insurer used them interchangeably in its briefs, the Minnesota Supreme Court confined its reading to the option the carrier had actually elected. Cedar Bluff Townhome Condominium Ass’n v. American Family Mutual Insurance Co., 857 N.W.2d 290 (Minn. 2014). So we make a carrier say in writing which clause it elected, and hold it there.
Functional equivalence is a floor, not the measure
“Functional equivalence” sounds like a legal standard. In first-party property insurance it is a defined term in exactly one place. ISO’s Functional Replacement Cost Loss Settlement endorsement, HO 05 30 10 00, defines functional replacement cost as the cost to repair or replace the damaged building “with less costly common construction materials and methods which are functionally equivalent to obsolete, antique or custom construction materials and methods used in the original construction.”
Read what that is. A cheaper valuation basis, sold by endorsement, reaching only materials that were obsolete, antique or custom in the original construction. Plaster, slate, leaded glass. Architectural shingles installed in 2004 are none of those. Virginia’s insurance regulator wrote the same distinction into its rulebook, capping functional replacement cost at the cost of “functionally equivalent property at a lower cost than would be required to replace the property with material of like kind and quality.” 14VAC5-342-70(D). Virginia governs nothing here and we are not pretending it does. It is quoted because a regulator drew the line for us: functionally equivalent means cheaper than like kind and quality.
So treat functional equivalence as a floor. Whatever goes back on your roof has to do everything the original did: wind rating, fire rating, service life, the warranty that came with it. It is not the measure of what you are owed. If your declarations page carries no functional or modified replacement cost endorsement, an adjuster pricing your claim as though it does is applying coverage you never purchased. Check the declarations and the forms schedule before you accept a functional substitute.
“Matching” is a word borrowed from somewhere else
No standard policy uses it. What people mean by matching is “a reasonably uniform appearance,” and that comes from a model insurance regulation, the NAIC Unfair Property/Casualty Claims Settlement Practices Model Regulation at section 9(A)(2), which a minority of states adopted. Tennessee adopted a narrowed version. Georgia and South Carolina adopted none. And before anyone treats a regulation as a sword: the model says twice, in its own text, that it creates no private cause of action.
That does not put appearance outside the contract. Construing the ordinary phrase “comparable material and quality,” the Minnesota Supreme Court read it to mean material “suitable for matching,” requiring “something less than an identical color match, but a reasonable color match nonetheless.” Every siding panel on twenty buildings was replaced. Cedar Bluff, 857 N.W.2d at 293–95. A federal judge in Washington framed it as plainly as it can be framed: does the policy pay for repairs that match, or repairs that “merely function”? That court found “other property of like kind and quality” could reasonably mean property that looks the same, held it ambiguous and ruled for the insured. National Presbyterian Church v. GuideOne Mutual Insurance Co., 82 F. Supp. 3d 55 (D.D.C. 2015). Both are persuasive reasoning from other states rather than law here, and neither holds that like kind and quality always requires a match.
So the order of argument matters. Your policy owes like kind and quality and like use. Matching is often what that produces once the facts are in. In Tennessee a state rule adds a uniform-appearance duty on top. We argue the contract first, because the contract is what a court enforces.
What like kind and quality does not mean
It has never meant identical, and we do not tell clients otherwise. The Texas Supreme Court held the phrase “neither restricted nor required” the insurer to pay only the cost of an identical replacement and that the policy “clearly allows more leeway than that,” then used that leeway against the insurer, affirming an award that cost the carrier more than an identical roof would have. Republic Underwriters Insurance Co. v. Mex-Tex, Inc., 150 S.W.3d 423, 426 (Tex. 2004). It ran on evidence: the roofer and the expert both testified the roofs were comparable.
The decision carriers cite for the opposite proposition does not say what they use it for. In Greene v. United Services Automobile Ass’n, 936 A.2d 1178 (Pa. Super. Ct. 2007), the court approved repairing one damaged slope because the substitute shingles were similar “in function, color, and shape.” Color was on the list. Greene is genuinely unhelpful to homeowners on how much of a roof gets replaced, and it construed “like construction” rather than “like kind and quality.” It matters for one reason: it turned on a similar shingle still being available.
Why a discontinued product changes the analysis
When no match can be bought, the question stops being about preference and becomes a question about what the covered property even is. The Seventh Circuit held that where hail damaged siding on two elevations and no matching siding remained on the market, the insurer had to replace all four sides, because the policy never says whether the covered property is a panel, an elevation or the building, and that ambiguity favors coverage. Windridge of Naperville Condominium Ass’n v. Philadelphia Indemnity Insurance Co., 932 F.3d 1035 (7th Cir. 2019), applying Illinois law. Illinois has no matching regulation, so that argument ran entirely on the policy, which is the shape of the argument in Georgia and South Carolina. Persuasive here, never controlling.
There is a real answer on the other side and you should hear it from us first. Claim the whole roof as one item and an insurer can respond that part of that item was worn out or defective, causes the policy excludes, and that you recover only what the storm caused. A Texas appellate court took that route in All Saints Catholic Church v. United National Insurance Co., 257 S.W.3d 800 (Tex. App. 2008). The age and condition of the undamaged planes are part of this fight.
Availability is the hinge. In Windridge the carrier argued a matching product had been on the market for roughly eighteen months after the storm, and you should expect a distributor letter saying a match exists. Unavailability has to be documented while it is still true, with named suppliers and dates, in writing. Our discontinued materials library exists for that job.
Where the three states we practice in actually stand
Georgia. No matching statute and no matching regulation. Georgia’s matching-style rule, Chapter 120-2-52, is written for personal private passenger motor vehicle claims, and a 2022 bill that would have written the national uniform-appearance standard into Georgia law was not enacted. The argument runs on your policy, and two things help. Georgia’s ambiguity threshold is unusually low: a provision is ambiguous if it is susceptible of two or more constructions “even when the multiple constructions are all logical and reasonable,” and O.C.G.A. § 13-2-2(5) then construes the ambiguity against the insurer that drafted it. Hurst v. Grange Mutual Casualty Co., 266 Ga. 712, 716 (1996). Standard policies do not define “like kind and quality.” And Georgia has construed that exact phrase: an insurer’s option to repair or replace with like kind and quality abates rather than eliminates the primary promise to pay the loss, and “repair” means restoration to substantially the same condition and value. State Farm v. Mabry, 274 Ga. 498 (2001), reviewing U.S. Fire Insurance Co. v. Welch, 163 Ga. App. 480 (1982). Every one of those Georgia decisions arose under automobile physical damage coverage. We say so, because a carrier will. The construction principle carries over; the coverage does not. The other Georgia levers are O.C.G.A. § 33-6-34 and the claim-handling deadlines.
Georgia, one planning point. Whether this dispute belongs to an appraisal panel or to a court depends on how the demand is written. The total amount of a conceded loss is a value question appraisal can reach; entitlement to a benefit the carrier says the policy does not provide is a courts question. Lam v. Allstate is what carriers reach for here, a narrow 4–3 pleading-stage decision with three dissenters, pulling against Clary, Bell and Omni. We frame the demand accordingly from the first inspection.
Tennessee. The only one of the three with a regulatory overlay, and it repays quoting precisely, because what circulates is usually the national model rather than what Tennessee adopted. TDCI Rule 0780-01-05-.10(1)(b): when replaced items “do not match in quality, color or size, the insurer shall replace items so as to conform to a reasonably uniform appearance according to the applicable policy provisions.” Tennessee dropped the model’s phrase “all items in the area” and added that qualifier, so the argument is the rule and your policy read together. Three limits belong in the same breath: the caption confines the rule to fire and extended coverage type policies with replacement cost coverage; paragraph .10(1)(a) leaves betterment with the insured, the reverse of the national model; and there is no line-of-sight limit anywhere in the Tennessee text, whatever an estimating platform prints. The statute behind the rule carries no private right of action, so it is a complaint lever and evidence of how your claim was handled rather than a lawsuit of its own. And where a loss-settlement provision bears more than one plausible meaning, the Tennessee Supreme Court has held the meaning favorable to the insured controls. Lammert v. Auto-Owners, 572 S.W.3d 170 (Tenn. 2019).
South Carolina. No matching statute, no matching regulation, and no reported South Carolina appellate decision on matching that we have located. South Carolina also reads these clauses more narrowly than most states. Its Supreme Court construed “repair or replacement,” read with the whole policy, to mean restoring pre-accident function and condition rather than value. Schulmeyer v. State Farm Fire & Casualty Co., 353 S.C. 491 (2003), an automobile case turning on State Farm’s own unusually specific definition. Older authority read a “like kind and quality” limitation to require restoration to substantially the pre-loss condition, Campbell v. Calvert Fire Insurance Co., 234 S.C. 583 (1959), and Schulmeyer limited that line. So the case is built on the policy’s own words, the physical facts and § 38-59-20. More at South Carolina claim law.
One caution, stated plainly: nobody can promise you a full roof. These claims are settled every day and denied every day, and the difference is almost always the quality of the documentation rather than the force of anyone’s opinion. Even the reported wins are often procedural. When a Missouri appellate court found “equivalent construction and use” close enough to argue about, what the homeowner got was a trial rather than a roof. Alessi v. Mid-Century Insurance Co., 464 S.W.3d 529 (Mo. Ct. App. 2015).
How you actually prove it
- Identify the material in writing. There is no stamp on the roof that says Chalet, and the court in the consolidated Atlas litigation said as much: no evidence was offered that each shingle carries a marking identifying it. That makes this an inspection rather than a glance, and it belongs in a dated document. Atlas sold a companion overlay called Stratford, and the parties in that litigation treated the two as indistinguishable for its purposes.
- Establish it cannot be bought. A dated supplier statement or manufacturer documentation turns your position into a fact. Do it while it is still true, because availability is the argument a carrier will make.
- Photograph what stays, not only what broke. In one Indiana case the homeowners prevailed on a record establishing two things: the house had a uniform appearance before the storm, and a mismatched roof and siding lower what the house is worth. Erie Insurance Exchange v. Sams, 20 N.E.3d 182 (Ind. Ct. App. 2014). Weathered roofs are rarely uniform and a carrier will say so, which is exactly why the undamaged planes get photographed too.
- Find the leftovers. The bundle in the garage, the wrapper in the attic, the builder’s spec sheet. People throw these out and then wish they hadn’t.
- Do not let a patch happen first. Once a mismatched repair is on the roof, you are arguing about something that has already been done.
The date of loss matters as much as the material. If you are not certain when the damage happened, our Storm Intelligence ledgers carry every significant hail, wind and tornado event in the counties we serve, with the official federal record behind each one.
Now you know the rule. Enforcing it against a carrier is a different job — and it's ours. A free, confidential case review by a licensed public adjuster takes three taps.
