How Hail Damage Affects Your Roof — And How to File an Insurance Claim

Illinois is one of the most hail-active states in the country. The southwest Chicago suburbs — including Orland Park, Tinley Park, Mokena, and Bolingbrook — sit directly in a hail corridor that sees multiple significant hail events each spring and summer. A single storm with golf ball-sized hail can compromise an entire neighborhood's worth of roofs in under 20 minutes.

The frustrating part: hail damage is often invisible from the ground and inside your home. Homeowners routinely live with a damaged roof for months before discovering the problem — after water intrusion has already compromised their insulation, decking, and ceiling drywall.

Here's everything you need to know about how hail damages your roof and how to file a claim that actually gets approved.

How Hail Actually Damages Asphalt Shingles

When hailstones strike asphalt shingles, they dislodge the protective granule layer on impact. The result is a small, dark, circular spot where the granules have been knocked away, exposing the black asphalt mat underneath. This exposed asphalt has no UV protection and will deteriorate rapidly — often cracking and failing within 1–3 years of the impact.

Large hail (1" diameter or more) can also crack the shingle fiberglass mat beneath the asphalt, creating a structural fracture that allows water to penetrate directly. These cracks are often invisible without getting on the roof and pressing the shingle to expose the break.

Beyond shingles, hail impacts metal components — ridge vents, pipe boots, step flashing, gutters, and downspouts. Dents and dings on these soft-metal components are often the most visible evidence of a hail event and are what insurance adjusters look for to confirm a storm claim.

Signs of Hail Damage to Look For

• Granules in gutters and downspout discharge. After a hail event, check your gutters. A large volume of loose granules is a strong indicator of impact damage to your shingles.
• Dents on gutters, downspouts, or AC condenser fins. These are easy to see from ground level and confirm that hail reached your property with enough force to cause damage.
• Dented or cracked roof vents. Aluminum ridge vents and pipe collars show hail hits clearly. If your vents are dented, your shingles almost certainly are too.
• Dark spots or bare patches on shingles. Visible from the ground with binoculars on a low-slope roof, these circular dark spots indicate granule loss from impact.
• Cracked or split shingles. High-velocity hail can physically split shingles, creating a visible fracture line.

The Insurance Claim Process: Step by Step

Step 1: Get a Professional Inspection First

Before you call your insurance company, have a licensed roofing contractor inspect your roof and document the damage in writing and photographs. This gives you an independent assessment that you control — not one generated by an adjuster whose job is to minimize the claim. A good contractor will provide a free inspection report with photos showing every impact point.

Step 2: File Your Claim Promptly

Most Illinois homeowner's insurance policies require you to file claims "promptly" — and many insurers use delayed filing as a reason to deny claims. File within 30 days of the storm event. You'll need the date of the storm, your policy number, and a general description of the damage. The insurer will assign you a claim number and schedule an adjuster visit.

Step 3: Have Your Contractor Present for the Adjuster Meeting

This is the single most important step most homeowners skip. Your roofing contractor should be on-site when the insurance adjuster inspects your roof. An experienced contractor knows exactly what adjusters look for, can point out damage that might otherwise be missed, and can dispute any items the adjuster overlooks. AJ Roofing provides on-site adjuster support as part of our storm damage service.

Step 4: Review the Scope of Loss

After the inspection, your insurer will send a Scope of Loss document listing what they agree to cover and the estimated cost. Review this carefully. Common items that get undercounted or missed include: ice & water shield, drip edge replacement, starter strip, ridge cap, and code-required upgrades. Your contractor can review the scope and flag any discrepancies.

Step 5: Understand ACV vs. RCV

Your policy likely pays on either an Actual Cash Value (ACV) or Replacement Cost Value (RCV) basis. ACV deducts depreciation — you may receive significantly less than the actual replacement cost upfront. RCV policies pay full replacement cost, with the depreciation "holdback" released after the work is completed. Know which policy you have before signing any contractor agreements.

Step 6: Choose Your Contractor Carefully

After a major hail event, out-of-town "storm chasers" flood the area offering to work directly with your insurance company. Be very cautious. Only hire licensed Illinois roofing contractors with a local address, verifiable reviews, and proper insurance. Never sign an Assignment of Benefits that signs over your insurance claim to a contractor — this removes your control over the process entirely.

What If My Claim Is Denied?

Insurance companies sometimes deny hail claims based on "normal wear and tear" or claim the damage is below the policy threshold. If you believe your claim was wrongly denied, you have the right to request a re-inspection, hire a public adjuster, or invoke your policy's appraisal clause. A public adjuster works on your behalf (typically for a percentage of the settlement) and can often overturn initial denials.
