Golf ball-sized hail detected near St. Joseph, MO on August 19, 2026
Hail was detected at a radar-indicated point within the St. Joseph 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 14 miles southeast of downtown St. Joseph, with one hail report logged in Buchanan County that day. At 1.75 inches, architectural asphalt shingles — the dominant material in St. Joseph — are vulnerable to granule loss, cracked tabs, and compromised mat integrity, particularly on roofs older than 10 to 15 years. Newer shingles may show limited visible damage while still sustaining functional impairment that affects waterproofing over time. Buchanan County recorded no larger strikes on this date, so this event represents the local ceiling for August 19.
On a home valued at the county median of $144,200, a 2% wind-hail deductible works out to approximately $2,884. Typical repair cost for a 2,000 square foot roof in this market runs $6,934, with the range falling between $5,673 and $8,195 — and full replacement averages $11,557. Get a professional inspection before making any insurance decisions.
At these numbers, the typical repair cost exceeds a standard 2% deductible. Contact your insurer — damage at this level is likely worth filing before you pay out of pocket.

Historical context
This event ranks 13th out of 69 recorded hail events of 1 inch or greater in Buchanan County over the past decade, placing it in the upper tier of magnitude but well below the county record of 2.75 inches set on May 24, 2020. August is historically quiet here — only two such events have been recorded in this month over ten years. Note that lower reporting density in this region is typical; actual hail exposure may be higher than the recorded count reflects.
Storm system
This was not an isolated cell. The same system produced 2.5-inch hail in Lancaster, NE and 4-inch (baseball-sized) hail in both Jackson, MO and Wyandotte, KS — indicating a large, organized storm complex crossing the region with St. Joseph on its lower-magnitude western fringe.
Contractor guidance
Local contractor data shows current backlogs running 2 to 4 weeks, which is moderate but can stretch quickly after a regional event of this scale given St. Joseph's limited post-storm capacity. The intake assessment rates storm chaser risk as moderate, consistent with the pattern of out-of-area contractors moving in after major regional hail events. Missouri does not require a state-level roofing license, but RSMo § 407.725 governs contractor conduct on insurance-related jobs and prohibits any contractor from offering to waive or rebate your deductible — that's a red flag, not a deal. Before signing anything, confirm the contractor carries general liability and workers' compensation insurance and has a verifiable local business presence.
Permits & building code
At 1.75 inches, many roofs will need repair rather than full replacement, though age and pre-existing condition are the deciding variables. Contractors pull permits in St. Joseph, an inspection is required, and permit costs typically run $150 to $350 — factor that into any estimate you receive. Class 4 impact-resistant shingles qualify for a 10–20% discount with most Missouri insurers.
- 1Photograph the roof, gutters, downspouts, siding, and any exterior HVAC equipment from ground level before conditions change.
- 2Schedule a professional roof inspection with a licensed, locally verifiable contractor — do not rely on a curbside assessment.
- 3Contact your insurer to report potential damage and ask specifically about your wind-hail deductible and the claim deadline in your policy declarations.
- 4Verify any contractor's general liability and workers' compensation coverage before allowing work to begin — ask for certificates, not just verbal confirmation.
- 5Keep copies of all inspection reports, estimates, photos, and insurer correspondence in a single file for reference throughout the claims process.
