Ping pong-sized hail detected near Ames, IA on June 17, 2026
Hail was detected at a radar-indicated point within the Ames monitoring area. Actual impact can vary by neighborhood, so nearby homes should use this as a signal to check roofs, gutters, siding, and vehicles.
Damage assessment
The radar-confirmed strike landed approximately 7 miles northwest of downtown Ames, with one hail report logged across Story County that day. At 1.5 inches, architectural asphalt shingles — the dominant material in Ames — typically show granule loss and surface bruising, but whether that crosses the line into functional damage depends heavily on shingle age. Roofs older than 15 years are more likely to show cracking or mat exposure; newer installations may show only cosmetic impact. The county's historical peak is 3 inches recorded on July 9, 2021 — this event was half that magnitude.
On a $350,000 home with a 2% deductible, the out-of-pocket threshold is $7,000 before insurance contributes. Typical repair cost for a 2,000 square foot roof in this area runs $6,243, ranging from $5,108 to $7,378. Get a professional inspection before making any insurance decisions.
At these numbers, you're better off repairing out of pocket — the typical repair cost falls below your deductible. Filing a claim likely isn't worth it unless a full inspection reveals significantly more damage.

Historical context
This event ranks 60th of 176 hail events measuring 1 inch or larger recorded in Story County over the past ten years, placing it in the middle of the county's documented history. The largest event on record hit 3 inches on July 9, 2021. June is historically an active month — 31 events in ten years — above the county's monthly average.
Storm system
Story County was not isolated: the same system produced marble-sized hail (0.75 inch) in both Woodbury and Polk Counties and half-dollar-sized hail (1.25 inch) in Johnson County, pointing to a multi-county weather event rather than a localized cell.
Contractor guidance
Local contractor data shows current backlogs of 1–2 weeks in the Ames market. Storm chaser risk is assessed as low for this area — most post-storm capacity comes from contractors based in larger nearby metros rather than traveling crews. Iowa Code § 103A.71 governs residential contractors performing insurance-related storm repairs and mandates specific contract disclosures; it does not require a separate state roofing license. Before signing anything, ask for proof of general liability insurance, workers' comp documentation, and confirm the contract includes the required Iowa consumer protection disclosures.
Permits & building code
At 1.5 inches, repair is the more likely outcome on a well-maintained roof — full replacement becomes the conversation when damage is widespread or the deck is compromised. The contractor pulls the permit in Ames, inspections are required, and permit costs typically run $100–$250. Class 4 impact-resistant shingles qualify for a 10–20% discount with most Iowa insurers.

- 2Get a repair estimate from a licensed contractor before contacting your insurer — at these numbers, out-of-pocket repair is likely cheaper than filing a claim.
- 3Verify any contractor's general liability insurance and workers' compensation coverage before allowing work to start.
- 4Keep a written record of all contractor conversations, quotes, and contracts — Iowa law restricts deductible waivers and post-loss assignment of benefits, so read every document before signing.
