How to File a Hail Damage Insurance Claim in Illinois (2026 Guide)

The Complete Guide to Hail Damage Insurance Claims in Illinois

Illinois ranks among the top ten states for hail damage claims every year. The corridor from Rockford through Chicago to Kankakee sits squarely in what meteorologists call Hail Alley. If your property has been hit by hail, the steps you take in the first 48 hours can mean the difference between a fully covered repair and an underpaid claim.

This guide walks you through the entire process based on our experience handling hundreds of claims across Chicago, Naperville, Aurora, Joliet, and communities throughout greater Chicagoland.

Step 1: Document the Damage Immediately

Before calling your insurance company, before cleaning up, document everything. Walk your entire property and photograph every instance of damage from ground level. Use your phone to shoot video walkthroughs. Pay special attention to roof shingles (look for granule accumulation in gutters), siding dents, damaged window screens, dented gutters, damaged air conditioning units, and any vehicle damage. Your independent documentation establishes a baseline that protects you if the adjuster misses items or underestimates damage severity.

Step 2: Get a Professional Roof Inspection

Hail damage to roofing materials is often invisible from the ground. What looks like a perfectly intact roof from your driveway may have hundreds of impact points where hailstones cracked shingles, displaced granules, or compromised the underlayment beneath. Allied Emergency Services provides free roof inspections throughout Illinois using drone technology and hands-on inspection to document every impact point with photographs and GPS coordinates. This inspection report becomes a powerful tool during the claims process.

Step 3: File Your Claim Promptly

We recommend filing within 48 hours of the storm event. Provide the date and time of the storm, a general description of damage, your policy number, and contact information. Do not agree to recorded statements at this point, and do not accept any settlement offer over the phone.

Step 4: Be Present for the Adjuster Inspection

When your insurance company sends an adjuster, be present for the inspection. Better yet, have your contractor present as well. Insurance adjusters are professionals, but they work for the insurance company. Having a knowledgeable contractor on-site ensures that all damage is identified and properly documented. At Allied, we attend adjuster inspections at no charge as part of our claims assistance service.

Step 5: Review the Initial Offer Carefully

In our experience across Schaumburg, Elgin, Arlington Heights, and other Chicagoland communities, initial offers are typically 30-50 percent below the actual cost of proper code-compliant repairs. Common items that get underestimated include ridge cap replacement, ice and water shield underlayment required by current building codes, drip edge, pipe boot replacements, and overhead and profit for the general contractor coordinating multiple trades.

Step 6: The Supplement Process

When the initial offer falls short, your contractor submits a supplement with line-item Xactimate estimates, code requirement documentation, manufacturer installation specifications, and photographic evidence supporting every item. This is where having an experienced storm damage contractor matters enormously. Allied Emergency Services prepares detailed supplement packages that recover the full cost of proper repairs.

Step 7: Know When to Escalate

If the supplement process does not produce a fair settlement, Illinois homeowners have several options. You can request a re-inspection by a different adjuster. You can file a complaint with the Illinois Department of Insurance. You can invoke the appraisal clause in your policy, which brings in independent appraisers to determine the loss amount. In rare cases, legal action may be necessary for insurance bad faith claims.

Illinois Building Code Requirements After Hail Damage

When your roof is replaced due to hail damage, the work must meet current International Residential Code requirements as adopted by Illinois. This often means upgrades beyond what was originally installed, including ice and water shield in valleys and at eaves (required in Cook, DuPage, Will, Kane, and Lake counties), proper ventilation meeting current code requirements, and drip edge installation. Your insurance company is obligated to pay for code-required upgrades under most Illinois homeowner policies. If your adjuster estimate does not include these items, a supplement is necessary.

Common Mistakes That Reduce Your Settlement

Do not sign any documents from your insurance company without reading them completely. Do not cash a check marked as final payment unless you agree it is final. Do not hire a contractor before your claim is filed. Do not let your insurance company choose your contractor for you. Do not accept a repair scope that does not meet current Illinois building codes.
