A cosmetic damage exclusion may exclude wind or hail damage that changes a roof’s appearance but does not affect how the roof works. On a metal roof, that often means dents without a puncture or leak. On an asphalt-shingle roof, it may mean granule loss or other surface marks.
The policy’s definition of “cosmetic damage” is the starting point. Some endorsements ask only whether water can get through the roof. Others ask whether the roof still protects the building from “the elements” to the same extent as before. Under that broader wording, the absence of a leak may not settle the issue if reliable evidence shows another measurable loss of present function.
Evidence that a roof may wear out sooner is different from evidence that it performs worse now. This guide explains how to read the endorsement, identify the relevant function, and evaluate the evidence. The form and governing law must be checked for each claim.
What does a cosmetic damage exclusion say?
ISO CP 10 36 10 12, Limitations on Coverage for Roof Surfacing, is one commercial-property endorsement that addresses cosmetic wind or hail damage. It contains two separate limitations that may be selected in its schedule:
- Paragraph A changes otherwise applicable replacement-cost treatment for roof surfacing to actual cash value.
- Paragraph B excludes cosmetic damage to roof surfacing caused by wind or hail.
Its operative exclusion begins:
“We will not pay for cosmetic damage to roof surfacing caused by wind and/or hail.”
Paragraph B defines cosmetic damage, in relevant part, as marring, pitting, or other superficial damage that changes the roof surfacing’s appearance but does not prevent it from continuing to function as a barrier to the elements to the same extent as before the damage.
The form’s schedule matters. A policy may apply Paragraph A, Paragraph B, or both to the listed building. Finding CP 10 36 in the form list is therefore not enough; the completed schedule must also be read.
Other residential and commercial endorsements use different definitions. Examples include wording that focuses on:
- actual water leakage or penetration;
- failure of the roof covering to perform its intended function;
- continued performance as a barrier to “the elements”; or
- performance as a barrier “to the same extent” as before the event.
Those variations are substantive. “No leak” may answer the question under a leak-specific form. It does not automatically answer every form that measures the extent of the roof’s present function.
Where does the limitation appear?
Cosmetic-damage language usually appears in an endorsement rather than the base coverage form. Start with the declarations and the schedule of forms and endorsements, then confirm that every listed form is present in the policy file.
Common titles include:
- “Limitations on Coverage for Roof Surfacing”;
- “Cosmetic Damage Exclusion”;
- “Exclusion of Cosmetic Damage to Roof Coverings Caused by Hail”; and
- “Roof Surfacing Limitation” or “Hail Damage Limitation.”
Do not rely on the title alone. Form numbers, edition dates, schedules, and definitions should be cross-checked against the complete endorsement. A policy described as “Special Form” or “Open Perils” can still contain a roof-surfacing limitation.
In Texas, for example, the Department of Insurance has prescribed residential endorsements HO-145 and TDP-022 in connection with certain impact-resistant roof-covering credits. Those forms define cosmetic damage and require the insured’s signature, subject to the forms’ record-retention language.
The Texas Windstorm Insurance Association’s 2026 guidelines likewise connect its cosmetic exclusion endorsement to a mandatory roof-covering credit and require a signed endorsement before the credit is applied. These requirements do not establish a rule for every Texas policy; they show why the particular program and form matter.
Why the definition of function matters
Cannon Falls: reduced lifespan versus present capacity
In Cannon Falls Area Schools, ISD 252 v. The Hanover American Insurance Company, No. 25-3315 (8th Cir. July 27, 2026), hail dented two metal school roofs. The hail did not puncture the metal, and neither roof had leaked after the storm. The policy excluded superficial damage that did not prevent the roof from functioning as a barrier to the elements “to the same extent” as before.
The federal district court granted summary judgment to the insurer. It treated the exclusion as a present-function inquiry and concluded that evidence of weakened roofs or shortened service life did not create a covered loss without a leak or other incursion of the elements.
The Eighth Circuit reversed in a 2–1 decision while sitting in diversity and predicting Minnesota law. That limits the decision’s reach, but not its practical point: a measurable present loss of load resistance can matter under “to the same extent” wording even before a roof leaks.
The Eighth Circuit separated two arguments:
- Reduced lifespan alone. The court agreed that the present-tense wording did not provide coverage merely because damage might shorten the time the roofs would remain effective in the future.
- Present loss of load resistance. The court held that a roof that can no longer resist the same snow weight or wind speed may not function as a barrier “to the same extent” as before, even if it has not yet leaked.
The appellate court vacated the judgment and remanded. It did not decide that the roofs were covered. The district court still had to address the admissibility and reliability of the insured’s expert testimony, and a factfinder could accept the insurer’s competing opinion. The court also noted that an insubstantial, unmeasurable, or inconsequential weakening could remain within the exclusion.
The practical point is narrow but important: evidence must match the definition. Under “to the same extent” wording, a measurable present change in load resistance may be relevant. A general statement about future deterioration or reduced service life is not the same evidence.
Different wording can produce a different result
The Cannon Falls court distinguished cases involving endorsements that required water leakage or penetration. It also distinguished a case in which the policyholder failed to disclose a metal-roofing expert to rebut the insurer’s expert evidence. These decisions reinforce two recurring questions:
- What function does this endorsement actually define?
- Is there admissible, methodologically sound evidence of a present change in that function?
What evidence can change the analysis?
Visible marks establish that the surface’s appearance changed. They do not, by themselves, establish either functional impairment or the absence of it. The relevant inspection and expert work depends on the material, roof assembly, damage mechanism, and policy definition.
Potentially relevant evidence may include:
- punctures, tears, cracks, open seams, or displaced components;
- water entry at the roof-covering level, even if water has not reached the building interior;
- quantified changes in structural or load-resisting capacity;
- damage to a coating or protective layer confirmed by an appropriate test;
- pre-loss specifications, manufacturer information, maintenance records, and prior-condition photographs; and
- a method that distinguishes storm-created conditions from manufacturing conditions, installation effects, wear, or ordinary weathering.
Asphalt shingles and granule loss
IBHS research identifies deformation, granule loss, and breach as distinct hail-impact damage modes. Its test-protocol commentary explains that granules protect underlying asphalt from ultraviolet degradation, but it also notes that manufacturers may apply excess granules and that some granule loss occurs during normal weathering. IBHS expressly states that its laboratory protocol is not intended as an insurance-claim or legal standard.
Granule loss therefore should not be treated categorically as either cosmetic or functional. The endorsement may expressly list it as cosmetic damage, and the cause and severity of the observed loss still require evidence. A reduced-lifespan theory based only on UV exposure also faces the distinction drawn in Cannon Falls between future longevity and present function.
Metal roofs, dents, and coatings
IBHS states that hail commonly dents metal roofing and that current research has not established that denting alone impairs roof function. A claim that a dent damaged a protective coating, seam, fastening system, or load-resisting capacity requires roof-specific evidence. It should not be inferred from the presence or number of dents.
Testing may be relevant when it is appropriate for the material and the claimed damage mechanism. The method, comparison baseline, sampling plan, and connection between the test result and the policy’s defined function should be documented. Coverage is then a separate policy-and-law question.
Hypothetical scope illustration
Assume a 15,000-square-foot commercial property has a 12-year-old standing-seam metal roof and a proposed full-replacement scope of $220,000. Hail dents are visible across approximately 80% of the panels. An engineer identifies test-supported coating damage in panels corresponding to $95,000 of the proposed scope, while testing does not identify coating damage in the remaining dented panels.
The evidence creates two factually different groups; it does not dictate the coverage result. The policy language, reliability of the testing, repairability, causation, and governing law still determine whether either group is covered and what amount is payable. The $95,000 figure should not be presented as an agreed settlement or as proof that coating damage necessarily defeats a cosmetic-damage exclusion.
How far does the exclusion reach?
The reach of an endorsement is determined by the property it names. ISO CP 10 36 defines “roof surfacing” broadly enough to include the surface material, securing materials, moisture-protection materials applied to or under the surface, and roof flashing. Its cosmetic-damage limitation is not, by its terms, a general exclusion for every exterior surface.
Other endorsements may address exterior wall surfacing, siding, windows, doors, or additional property. Before deciding what to inspect or how to organize a scope, identify:
- the listed premises and buildings;
- the property or surface covered by the definition;
- the causes of loss to which the limitation applies; and
- whether the endorsement changes valuation, excludes cosmetic damage, or does both.
Which policy period applies?
The policy in force when the physical damage occurred is ordinarily the starting point. If a cosmetic exclusion was added at renewal, reliable weather data and condition evidence may help determine whether damage occurred during an earlier period.
That evidence does not move a loss to an earlier policy period by itself. The insured must still establish when the damage occurred and satisfy the applicable policy conditions. Late notice, prior damage, prejudice, suit limitations, and state law may all affect the result. A generic “discovery trigger” or notice-prejudice rule should not be assumed. When damage may span policy periods, the relevant policies and governing law should be reviewed with coverage counsel.
FAQ
Does a cosmetic damage exclusion apply to hail damage on every roof type?
Not automatically. The result depends on the endorsement, the scheduled building, the defined property, and the cause of loss. ISO CP 10 36 addresses roof surfacing, which can include shingles, tiles, cladding, metal or synthetic sheeting, securing materials, moisture-protection materials, and flashing. Proprietary forms may define a different scope.
Can a visibly damaged roof be covered even if it is not leaking?
Possibly. Leak- or penetration-specific wording can make the absence of water entry decisive. Under “to the same extent” wording, Cannon Falls held that reliable evidence of a measurable present loss of wind- or snow-load resistance could create a fact issue even without a leak. Reduced lifespan alone was insufficient.
How is a cosmetic damage exclusion different from functional replacement cost?
They address different questions. A cosmetic damage exclusion determines whether specified damage is covered. Functional replacement cost is a valuation provision that can limit payment to the cost of a functionally equivalent replacement. A policy may contain both.
What is the difference between ISO CP 10 36 and a proprietary endorsement?
CP 10 36 10 12 is a scheduled commercial-property endorsement with two selectable limitations: actual-cash-value treatment for roof surfacing and exclusion of cosmetic wind or hail damage. Proprietary and residential forms may use different property definitions, damage examples, functional tests, signature requirements, or valuation rules. The form number and edition should be verified rather than inferred from a similar title.
For Policyholder Representatives
The intake decision should follow the endorsement’s text and the available physical evidence. Do not commit to a functional-damage theory before confirming that the policy language makes that function relevant and a qualified expert can test it reliably.
Claim Intake Checklist for Policyholder Representatives
| # | Question | Why it matters |
|---|---|---|
| 1 | Is a cosmetic-damage or roof-surfacing endorsement listed, and is the complete form present? | The form schedule may reveal a limitation that is absent from the base coverage form. A missing endorsement must be obtained before the analysis is complete. |
| 2 | Which paragraph or option is selected for the building? | CP 10 36, for example, can change valuation, exclude cosmetic damage, or do both. |
| 3 | What property and causes of loss does the endorsement identify? | The wording may be limited to roof surfacing and wind or hail, or may reach other exterior property. |
| 4 | How does the form define function: water leakage, penetration, intended function, “the elements,” or performance “to the same extent”? | The definition determines which physical facts are relevant. |
| 5 | Does the form expressly identify denting, marring, pitting, or granule loss as cosmetic? | Enumerated damage types can narrow an argument based only on the listed condition. The full definition still must be read. |
| 6 | What observed condition is claimed to be a present functional change? | Visible damage and expected future deterioration are not substitutes for evidence tied to the policy’s definition. |
| 7 | Is qualified expert work needed, and is the proposed method reliable for this roof assembly? | Expert admissibility and methodology remained unresolved after the appellate decision in Cannon Falls. |
| 8 | Can the evidence distinguish storm damage from prior damage, installation conditions, manufacturing conditions, and weathering? | Causation and timing must be supported independently of the coverage argument. |
| 9 | Is an earlier policy period genuinely implicated? | The date of physical damage, policy conditions, late notice, and state law must be evaluated before presenting a claim under another period. |
| 10 | Is coverage counsel needed? | Form interpretation, expert strategy, multi-period issues, and jurisdiction-specific law can exceed routine claim handling. |
Keep the claim narrative, photographs, test results, expert conclusions, and estimate consistent about what is observed, what is inferred, and what remains disputed. Contractors and inspectors can document conditions within their expertise; policy interpretation and legal conclusions should remain with appropriately licensed professionals and counsel.
