A hailstorm hit your neighborhood. You spotted dents on your roof and filed a claim. Now the insurer says the damage is minor — or claims it existed before the storm. That response is not uncommon. But it does not mean the insurer is right.
Wind and hail make up 42.5% of all homeowners insurance claims in the country, according to the Insurance Information Institute (2025). Despite that volume, according to Weiss Ratings (2024), 37.4% of all homeowner claims closed without any payment. If your claim is stalled, underpaid, or denied, you have options under Illinois law.
How Hail Threatens Illinois Homes
How common is damaging hail across northern Illinois?
Hailstorms strike the Chicago area and surrounding counties with surprising regularity. The NWS Chicago forecast office (2005–2024) reports that the northern Illinois region averages 10 to 15 days each year with damaging hail of at least one inch. On two to three of those days, hailstones reach two inches or more. The Illinois State Climatologist Office (1995) puts the statewide average at roughly 2.0 to 2.5 hail days per year.
Are severe storms getting more frequent in Illinois?
Yes — and the trend is sharp. According to NOAA (1980–2024), billion-dollar weather disasters affecting Illinois averaged 2.8 per year over the full historical record. Between 2022 and 2024, that number jumped to 8.7 per year. Severe storms made up 92 of the 128 billion-dollar disasters in Illinois since 1980. More storms mean more roof damage, more claims, and more disputes.
How much do roof repairs cost after a hailstorm?
A full roof replacement in Illinois typically costs $8,000 to $25,000. According to Verisk’s U.S. Roofing Realities Trend Report (2025), residential roof claim costs hit roughly $31 billion nationwide in 2024 — up about 30% since 2022. Material costs have soared too. The Bureau of Labor Statistics via AGC (2026) shows the Producer Price Index for asphalt felts and coatings rose 38.4% from February 2020 to January 2026. Your insurer’s estimate may not reflect current repair prices.
Proving Your Hail Damage Claim Under Illinois Law
What do you need to show the insurer?
If your standard homeowners policy is an all-risk policy, it covers any sudden, accidental loss unless the policy excludes it. Under Illinois law, your initial burden is light. You need to show three things:
- An all-risk policy existed covering the property
- You had an insurable interest — you owned the home
- The loss was fortuitous — caused by an unexpected event like hail
Once you show those three things, the burden shifts. The insurer must then prove an exclusion applies to deny your claim.
What if the insurer blames wear and tear instead of the storm?
This is the most common dispute in hail claims. Your insurer may say the roof was already worn out. Illinois uses the efficient proximate cause doctrine as its default rule. Coverage exists when the covered peril — hail — was the dominant cause, even if wear played some role. An inspection by a licensed contractor or engineer (often around $300 to $600) can identify the specific impact marks and fracture patterns that separate storm damage from aging. That evidence is critical.
What does an anti-concurrent causation clause mean for your claim?
Some policies include language designed to block coverage when covered and excluded causes overlap (also known as anticoncurrent-causation clauses). In Bozek v. Erie Ins. Grp., 2015 IL App (2d) 150155 (2d Dist. 2015), an Illinois appellate court upheld this type of clause. But the Illinois Supreme Court has not ruled on whether these clauses always hold up. When hail alone caused the damage and wear is just a pre-existing condition — not a concurrent cause — the clause may not apply.
Filing Rules That Can Make or Break Your Claim
Do you need to file a sworn proof of loss?
Yes — and the details matter. Most Illinois policies require a signed, sworn, notarized proof of loss within a set window, usually 60 days. Illinois generally requires strict compliance. An unsigned or unnotarized document may not count. A proper filing also triggers a key protection. Under 215 ILCS 5/143.1, your claims deadline pauses from the date you file your proof of loss until the date the insurer denies your claim (in whole or in part).
Can the insurer waive that requirement?
It can — and often does without realizing it. In McMahon v. Coronet Ins. Co., 6 Ill. App. 3d 704, 286 N.E.2d 631 (1st Dist. 1972), the court held that an insurer waives the proof of loss requirement when it denies a claim on coverage grounds without ever raising the proof of loss defense. The insurer cannot reject your claim for one reason and then penalize you later for missing paperwork it never mentioned.
How soon must you report hail damage?
Report it as soon as you find it. Under Country Mut. Ins. Co. v. Livorsi Marine, Inc., 222 Ill. 2d 303, 856 N.E.2d 338 (Ill. 2006), late notice can cost you coverage entirely — even if the delay did not hurt the insurer. Illinois courts look at whether the delay was reasonable and excusable. After a hailstorm, photograph the damage and call your insurer right away.
What should you look for in the denial letter?
If your hail claim is denied, check whether the letter cites specific policy language. Under 50 Ill. Admin. Code § 919.50(a)(1), every denial must clearly set forth the policy definition, limitation, exclusion, or condition it relies on. A vague rejection that says “pre-existing wear” without pointing to specific policy terms may fall short of that standard. In McGee v. State Farm Fire & Cas., 315 Ill. App. 3d 673, 734 N.E.2d 144 (2d Dist. 2000), the court stressed that the quality of the insurer’s investigation is central to whether its conduct rises to the vexatious and unreasonable standard under Section 155. If your insurer denied your hail claim without inspecting the roof or ignored your contractor’s findings, that weak investigation can support your case.
The Appraisal Process for Hail Damage Cost Disputes
What is appraisal and when does it apply?
Appraisal is a process built into most homeowners policies for resolving disagreements over how much damage costs. Each side picks an appraiser (often around $500 to $2,000 each). If they cannot agree, an umpire ($1,500 to $5,000) breaks the tie. Appraisal only addresses the dollar amount of the loss. It cannot decide whether your policy covers the damage.
Can appraisers decide which damage came from hail?
To some extent, yes. In Xiang Zhao v. State Farm Fire & Cas., Co., 2025 IL App (2d) 240723, 266 N.E.3d 1229 (2d Dist. 2025), the court addressed this directly. The insurer had already acknowledged hail damage and made a partial payment. The remaining dispute — whether hail also harmed other roof components — was an amount of loss question that belonged in appraisal. The court said that “resolving some questions of causation will be necessarily included in the appraisal process.”
Can my insurer avoid appraisal to keep my payout low?
Some try. A common tactic is to relabel a loss-amount dispute as a “coverage” question — since coverage fights are not meant to go to appraisal. But in Xiang Zhao, State Farm made partial payment on a hail damage claim and then refused appraisal, arguing the dispute was about coverage rather than the amount of loss. The court disagreed — if an insurer acknowledges a covered loss through partial payment, it cannot recast a valuation disagreement as a coverage question to sidestep the appraisal process.
An insurer can also forfeit its appraisal rights through delay. In Lundy v. Farmers Group, 322 Ill. App. 3d 214, 750 N.E.2d 314 (2d Dist. 2001), the insurer waited years, filed motions, and served discovery before demanding appraisal. The court found that conduct “so inconsistent with the appraisal clause as to demonstrate the abandonment of its right to an appraisal.” Stonewalling or misusing the appraisal process can strengthen a Section 155 claim.
Does Illinois law shift appraisal costs to the insurer?
Yes. Under 215 ILCS § 5/397.05, if you have a fire or extended coverage policy (which includes standard homeowners policies covering hail), request appraisal, and your full loss amount is upheld, the insurer pays both your appraiser’s fee and the umpire’s fee. This removes a cost barrier for you. It also pushes insurers to make fair offers before appraisal, since losing costs them more.
Frequently Asked Questions
What penalty can an insurer face for an unreasonable denial?
Under 215 ILCS 5/155, a court can award attorney fees, costs, and a statutory sanction — capped at the lesser of 60% of your recovery, $60,000, or the gap between your recovery and any pre-suit offer — if the insurer’s conduct was “vexatious and unreasonable.” The penalty, combined with consequential damages and prejudgment interest, can significantly exceed the original claim. For a full breakdown of how Section 155 works, see our guide on bad faith insurance claims in Illinois.
Does a coverage disagreement automatically prove unreasonable conduct?
No. A genuine dispute can shield the insurer — but only when it has an actual factual basis for its position. In McGee v. State Farm Fire & Cas., 315 Ill. App. 3d 673(2d Dist. 2000), the insurer’s mere assertion of a defense without a factual basis did not create a bona fide dispute.
How long do I have to file a lawsuit over a denied hail claim?
Most homeowners policies set a one- to two-year deadline from the date of loss. Under 215 ILCS 5/143.1, that deadline pauses while your proof of loss is pending and until the insurer issues a denial (in whole or in part). Without a shortened deadline in the policy, the default statute of limitations for written contracts in Illinois is 10 years under 735 ILCS 5/13-206. File your sworn proof of loss early to protect your right to sue.
