Golf ball-sized hail detected near Des Moines, IA on September 8, 2026
Hail was detected at a radar-indicated point within the Des Moines 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 detection point was approximately 10 miles north of downtown Des Moines, with one report logged in Polk County for the day. At 2.25 inches, golf ball-sized hail routinely causes functional damage to architectural asphalt shingles — cracked or missing granules, compromised mat integrity, and in some cases punctures. Roofs older than 15 years are more vulnerable; granule loss accelerates on aged shingles, and what looks cosmetic on a newer roof can be functional damage on an older one. The county's historical maximum is 3.25 inches, recorded on July 9, 2021, so this event is meaningful but not the upper end of what Polk County has seen.
On a $350,000 home with a 2% wind/hail deductible, the out-of-pocket threshold is $7,000. Typical repair costs for a 2,000 sq ft roof run $6,965 — with the range falling between $5,699 and $8,231. 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.

Contractor guidance
Local contractor data shows current backlogs of 4 to 8 weeks in the Des Moines market following storm events. The storm chaser risk here is rated high — Des Moines is a primary target for out-of-state roofing crews, and door-to-door solicitation typically begins within 24 to 48 hours of a notable storm. Iowa Code § 103A.71 governs residential contractors performing insurance-related storm repairs and mandates specific contract disclosures; ask for those disclosures in writing before you sign anything. Also verify proof of general liability insurance and workers' compensation before any work begins.
Permits & building code
At 2.25 inches, whether a roof needs repair or full replacement depends on shingle age, condition, and how directly the storm track passed overhead — a professional inspection is the only way to know. The contractor pulls permits in Des Moines, inspections are required, and permit costs typically run $150 to $400. Class 4 impact-resistant shingles qualify for a 10–20% discount with most Iowa insurers.
