Prove the material is discontinued
Measure the exposure width, nailing strip and interlock. If an ITEL report confirms the shingle or siding profile is discontinued, weaving new pieces into old courses can void the manufacturer warranty.

Key facts at a glance
- Statutory matching states (including OH, FL, KY, CT, RI, UT, CA, IA, NE, AK) require a reasonably uniform appearance when replaced materials do not match undamaged areas.
- When 20% of a roof or siding elevation is storm-damaged, a patch-only payout averages $2,200–$4,800, while a full matching replacement averages $12,500–$24,000.
- An ITEL laboratory material test report ($125–$225) documents whether a damaged shingle or vinyl siding profile is discontinued and has no compatible match.
- Many insurers now attach a Cosmetic or Matching Sublimit Endorsement ($5,000–$10,000 cap) at renewal that overrides general policy matching.
- Dimensional incompatibility—such as old 36-inch English metric shingles vs modern 39-3/8-inch shingles—is a physical repair issue, not merely cosmetic.

Roof and siding insurance matching laws: every numbered part explained
The roof and siding insurance matching laws drawing above has 9 numbered parts, from Damaged roof slope to Lab identification report. Each card below frames one of them, with what to check on a quote or claim.
1 Damaged roof slope
Paid in every state
The slope or wall the storm actually hit is covered under the policy wherever you live. It is the minimum the insurer must replace, and the base of every matching argument.
What moves it: Area damaged, material and its age.
On the quote: Photograph damage on each slope or wall with a chalk circle and a tape for scale.
2 Undamaged slopes that must match
The main matching cost
When the new shingles cannot match the old ones, replacing the damaged slope alone leaves a roof that looks patched. Matching rules decide whether undamaged slopes are replaced so the roof looks uniform.
What moves it: Your state's rule, the material and how much of the roof is visible together.
On the quote: Ask the adjuster in writing how the matching area was defined and which slopes are included.
3 Siding wall repaired in a new color
Treated like roof slopes
Siding faded by years of sun rarely matches new panels, even of the same color name. Replacing one wall can leave a visible line where old and new meet at a corner.
What moves it: Siding type, color, fade and where the walls meet.
On the quote: Photograph walls that are seen together and any color difference with a sample panel held up.
4 Discontinued product evidence
Strengthens the claim
A letter from the manufacturer or a lab identification report showing the product is discontinued, or has a different size or profile, is the strongest support for a matching request.
What moves it: The material, its age and whether the line is still made.
On the quote: Get a material identification report and keep the manufacturer's discontinuation notice.
5 Line of sight from the street
Common test for siding
Many matching rules ask whether the repaired and unrepaired areas are seen together, for example from the street or from one side of the house.
What moves it: House layout and which faces are visible together.
On the quote: Take photos from the street and from each corner that show the faces together.
6 Your state’s matching rule
Rules vary by state
Some states have a specific matching regulation, others rely on court decisions or the policy language, and some have no rule at all. A few policies also add cosmetic-damage or matching exclusions.
What moves it: Your state and your policy wording.
On the quote: Check your state insurance department's rules and read your policy for a matching or cosmetic exclusion.
7 Payout with matching
Shown in your result
With matching, the payout can be several times the single-slope figure because it covers the undamaged areas as well. The calculator shows both so you can see what is at stake.
What moves it: Matching tier, damaged share and the material.
On the quote: Submit the matching request in writing with your photos and material report.
8 Starter, flashing and trim
Added with the matched area
Replacing more of the roof or siding also means new starter strips, flashing, underlayment or housewrap and transition trim where new meets old. These items are easy to leave off an estimate.
What moves it: How much area is replaced and the number of edges and openings.
On the quote: Ask that starter, flashing, underlayment or housewrap and trim be listed as separate lines.
9 Lab identification report
$150–$325
A lab can identify the shingle or siding brand, size and color and test brittleness, which shows whether a repair can be done without damaging the surrounding material or whether a match exists.
What moves it: Material type and the lab chosen.
On the quote: Ask whether the insurer will order the sample or reimburse the report.
Line of sight & material compatibility
How adjusters and appraisers evaluate a matching dispute
Winning a roof or siding matching supplement depends on three pieces of evidence: physical profile compatibility, line-of-sight visibility, and your state's unfair claim settlement statute.
Zoom in on three spots in the photo: these are the lines a roof and siding insurance matching laws bid should spell out. These close-ups are crops of the same AI-generated illustration.
Document adjoining planes from ground level
Stand at the street and back yard where two walls or roof slopes meet in a single line of sight. Courts and statutes focus on whether the mismatch is obvious from normal viewing angles.
Check state rule vs matching endorsements
Statutory matching states require insurers to match adjoining areas unless the policy carries an approved matching exclusion or sublimit endorsement.
Before you sign a quote or file a claim, verify these three details
- Dimensional match
- Whether the new shingle or siding locks into the existing course height without cutting or unsealing tabs
- State regulation
- Whether your state enforces statutory line-of-sight matching (e.g. OH, FL, KY, CT, RI, IA, NE, UT, CA, AK)
- Policy endorsement
- Whether your declarations page lists a Matching Sublimit or Cosmetic Damage Exclusion endorsement

State-by-state roof and siding matching rules (2026 reference)
Homeowners insurance policies promise to repair or replace damaged property with material of like kind and quality. However, states differ sharply on whether "like kind and quality" applies only to the 20 storm-damaged shingles on one slope or requires replacing the undamaged slopes so the exterior retains a reasonably uniform appearance.
| State Matching Tier | States Included | Key Statute / Rule | Typical Claim Outcome When Material Is Discontinued |
|---|---|---|---|
| Tier 1: Strict Statutory / Regulatory Matching | OH, FL, KY, CT, RI, UT, CA, IA, NE, AK | Ohio Admin. Code 3901-1-54; Fla. Stat. § 626.9744; 806 KAR 12:095; Conn. Gen. Stat. § 38a-316e; 10 CCR § 2695.9; Iowa Admin. Code r. 191-15.44 | Insurer must replace undamaged adjoining slopes/walls in the same line of sight to achieve a reasonably uniform appearance. |
| Tier 2: Case-Law / Appraisal Matching | MN, IL, IN, MD, MO, NC, TN, WI, WA | State "like kind and quality" decisions & appraisal panel awards | Full slope or elevation replacement is often awarded when dimensions don't interlock or mismatch is stark from the street. |
| Tier 3: Policy-Language / Patch Default | TX, CO, OK, GA, PA, NY, VA, SC, AZ | Governed strictly by policy contract & matching endorsements | Direct physical loss covers only damaged slopes unless physical incompatibility (e.g. non-interlocking siding or brittle shingles) prevents a watertight patch. |
Rules change and courts read them differently. This table is a planning summary, not legal advice — confirm the current rule with your state insurance department or a licensed attorney or public adjuster before relying on it in a claim.
Why physical incompatibility beats a color-fade argument in every state
Even in states without a matching statute (such as Texas, Colorado, or Pennsylvania), insurers are usually still expected to pay for a full slope or wall replacement when a patch repair is physically or mechanically impossible without damaging surrounding materials:
- The Brittle Shingle / Mat-Transfer Test: Lifting the tab of a 14-year-old shingle to nail in a replacement shingle beneath it often creases or tears the brittle fiberglass mat above it, creating a domino effect up the slope.
- Imperial vs. Metric Shingle Dimensions: Older 3-tab and architectural shingles measured 12" × 36" with a 5-inch exposure, whereas current architectural shingles measure 13-1/4" × 39-3/8" with a 5-5/8-inch exposure. Cutting down modern shingles voids the wind warranty and misaligns sealant strips.
- Discontinued Vinyl Siding Locks: Vinyl siding profiles vary by butt thickness (1/2" vs 5/8" vs 3/4"), exposure (4" vs 4.5" vs 5" Dutch lap), and nailing-hem hook geometry. If an ITEL report shows the lock profile is discontinued, a patch will unzip in the next windstorm.
Worked example: how a discontinued shingle or siding claim moves from $3,400 to $17,800
Suppose a windstorm tears 18 tabs off the front slope of a 14-year-old roof (or hail cracks 12 courses of vinyl siding on the west gable wall). The initial field adjuster writes an estimate for direct physical damage only—replacing 3 squares of shingles on one slope ($2,650) plus ridge cap and flashing ($750) for a total of $3,400. After subtracting your $2,500 deductible, the initial settlement is $900.
Your contractor pulls a single loose shingle tab (or a 6-inch piece of cracked vinyl siding from behind a downspout) and submits it to ITEL Laboratories, while also filming a continuous, unedited video of a brittle repairability test showing that lifting the surrounding 14-year-old tabs to nail in new shingles creases the fiberglass mat above them. Look at how those two steps change the claim math across the three state tiers:
| Claim Stage / State Rule | Approved Scope | Deductible | RCV Total Payout | Why the Number Moves |
|---|---|---|---|---|
| 1. Initial Adjuster Estimate (Patch Only) | $3,400 | $2,500 | $900 | Prices only the 3 directly wind-damaged squares without testing match or repairability. |
| 2. Failed Brittle Test / Single-Slope Match | $8,900 | $2,500 | $6,400 | Because surrounding shingles crease when lifted, the entire damaged slope/wall must be replaced to the ridge and valleys. |
| 3. Statutory Line-of-Sight Match (OH, FL, KY, CT, RI) | $17,800 | $2,500 | $15,300 | ITEL confirms the 36-inch shingle or siding profile is discontinued; statute requires matching all adjoining visible planes. |
Step-by-step checklist for submitting a roof or siding matching supplement
- Request the adjuster's exact line-item Xactimate estimate: Verify the exact product code (e.g.,
RFG 300vsRFG 240orSDG VINYL) and how many squares or square feet were allowed. - Order an ITEL sample report ($125–$225): Never rely on a visual guess that a shingle or siding board is discontinued. Attach the written ITEL report showing the manufacturer, discontinuation date, exposure width, and whether any distributor stock exists within 100 miles.
- Document dimensional incompatibility first, appearance second: Adjusters are trained to push back on pure "color fade" arguments. If the old shingle is 36 inches wide and modern shingles are 39-3/8 inches wide—or if the vinyl siding lock hooks do not engage—lead with the mechanical incompatibility and manufacturer warranty requirements.
- Cite your state's unfair claim settlement regulation or appraisal clause: In statutory states, reference the exact administrative code section (such as Ohio Admin. Code 3901-1-54(I)(1)(b) or Fla. Stat. § 626.9744) in a brief, polite cover email alongside ground-level line-of-sight photographs.
Matching claim cost by region
The calculator's default matching claim scenario, repriced for each of its six regions. At the national average it runs $12,666 – $19,519; South / Lower Midwest is the lowest at $11,039 – $17,024, and West Coast metro is the highest at $16,421 – $25,277, a gap of about $6,818 at the midpoint.
| Region | Planning range | Midpoint |
|---|---|---|
| National average | $12,666 – $19,519 | $16,092 |
| South / Lower Midwest | $11,039 – $17,024 | $14,032 |
| Mountain / Plains | $12,040 – $18,559 | $15,300 |
| Mid-Atlantic / Upper Midwest | $14,168 – $21,822 | $17,995 |
| Northeast metro | $15,920 – $24,509 | $20,214 |
| West Coast metro | $16,421 – $25,277 | $20,849 |
What “Damaged exterior system” does to the price
Every other input stays at its default and only “Damaged exterior system” changes. The cheapest choice, 3-tab asphalt shingle roof (often 36″ discontinued), comes to $11,172 – $16,780; the most expensive, Fiber-cement / wood house siding, comes to $25,365 – $44,170.
| Choice | Planning range | Midpoint vs default |
|---|---|---|
| Architectural asphalt shingle roof (default) | $12,666 – $19,519 | — |
| 3-tab asphalt shingle roof (often 36″ discontinued) | $11,172 – $16,780 | −$2,116 |
| Vinyl house siding | $15,405 – $29,230 | +$6,225 |
| Fiber-cement / wood house siding | $25,365 – $44,170 | +$18,675 |
What “Material availability & ITEL test” does to the price
Every other input stays at its default and only “Material availability & ITEL test” changes. The cheapest choice, Exact match available locally, comes to $3,426 – $5,244; the most expensive, Discontinued profile / dimensionally incompatible (+ITEL & tie-in), comes to $12,666 – $19,519.
| Choice | Planning range | Midpoint vs default |
|---|---|---|
| Discontinued profile / dimensionally incompatible (+ITEL & tie-in) (default) | $12,666 – $19,519 | — |
| In production but weathered / color mismatch | $12,516 – $19,194 | −$238 |
| Exact match available locally | $3,426 – $5,244 | −$11,758 |
How age changes the matching claim claim payout
Using the default job, a $2,500 deductible and a 28-year expected life. At 10 years old, about $5,747 is held back as depreciation; a replacement cost policy releases it after the work is finished, while an actual cash value policy keeps it.
| Age | Wear | First check | Held back |
|---|---|---|---|
| 2 years | 7% | $12,443 | $1,149 |
| 5 years | 18% | $10,719 | $2,874 |
| 10 years | 36% | $7,845 | $5,747 |
| 15 years | 54% | $4,972 | $8,621 |
| 20 years | 71% | $2,098 | $11,495 |
| 30 years | 80% | $718 | $12,874 |
How a matching request usually runs
| Stage | Typical time | What happens |
|---|---|---|
| Document | 1 – 7 days | Photos, samples and product details. |
| Lab report | 1 – 3 weeks | Material identification if needed. |
| Written request | 1 day | Citing your state rule and the evidence. |
| Insurer response | 2 – 6 weeks | Approval, partial approval or denial. |
| Next steps | Varies | Appraisal or a complaint to the state insurance department. |
Keep a copy of every message and photo; matching disputes often turn on the documentation.

Frequently asked questions
Which states have roof and siding insurance matching laws?
States with explicit statutes or insurance department regulations requiring insurers to match undamaged areas for a reasonably uniform appearance include Ohio, Florida, Kentucky, Connecticut, Rhode Island, Utah, California, Iowa, Nebraska and Alaska. Several other states enforce matching through court precedent or appraisal.
What is an ITEL report in a roof or siding insurance claim?
ITEL Laboratories is an independent testing service used by insurance adjusters and contractors. You mail a sample of the damaged shingle or siding piece, and ITEL returns a lab report identifying the exact manufacturer, profile, dimensions, whether the product is discontinued, and whether any closest-match distributor stock exists.
Does insurance have to replace all siding if only one wall is damaged?
In statutory matching states, if the vinyl or fiber-cement siding is discontinued or weathered so that replacing one wall creates an obvious mismatch in the same line of sight (such as the front and side corner of the house), the insurer generally owes for the adjoining visible walls. In non-matching states, full replacement usually requires showing that the siding interlock profile is no longer manufactured.
What is the line-of-sight rule in homeowners insurance?
The line-of-sight rule states that when a repair is made, all elevations or roof planes visible at the same time from a normal ground-level viewing point must present a reasonably uniform appearance. If the front roof slope is visible from the street and the back slope is hidden by the ridge, an insurer may pay to replace the entire front slope while patching the rear using harvested shingles.
Can an insurance company harvest siding or shingles from another side of my house?
Yes, harvesting is a common compromise. If a closet wall, dormers, or a rear garage wall uses the exact same discontinued siding or shingle, an adjuster may pay labor to remove intact pieces from the less-visible rear wall to patch the front storm damage, and then re-side the entire rear wall with new material.
Do matching laws apply to Actual Cash Value (ACV) policies?
Even in statutory matching states, if your policy settles on Actual Cash Value (ACV) rather than Replacement Cost Value (RCV), age depreciation is still subtracted from the expanded scope, and many recent policies attach a specific Matching Exclusion or $10,000 Matching Sublimit endorsement.
Is Illinois a matching state for siding?
Yes. Illinois’ claims rule, 50 Ill. Adm. Code 919.80(d)(3)(A), says that when replaced items do not match in quality, color or size, the insurer must replace all items in the area so they conform to a reasonably uniform appearance. Courts have applied it to siding on walls that are seen together. Your policy’s own wording, and any matching exclusion, still matter.
