Baseball-sized hail detected near Bismarck, ND on June 29, 2026
Hail was detected at a radar-indicated point within the Bismarck 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 point was approximately 13 miles north of downtown Bismarck, with one hail report logged in Burleigh County that day. At 4 inches, hail this size causes functional damage — not cosmetic — to standard architectural asphalt shingles. Granule loss, cracked tabs, and compromised underlayment are expected outcomes, and any roof older than 10 years faces a higher probability of full structural failure at the impact points. Burleigh County's largest recorded event reached 4.5 inches on July 29, 2024, so this event sits just below that threshold.
On a $350,000 home with a 2% deductible, the out-of-pocket threshold is $7,000 before insurance begins paying. Typical repair cost for a 2,000 sq ft roof after an event of this magnitude runs $7,257, with a range of $5,938 to $8,577 depending on roof condition, pitch, and materials. 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
Among 150 hail events of 1 inch or greater recorded in this area over the past 10 years, this event ranks third by magnitude — a meaningful position in a well-documented record. The county's largest event on record reached 4.5 inches on July 29, 2024. June is historically active here, averaging more than four events per month over the past decade, so this storm fits a well-established seasonal pattern rather than representing an anomaly.
Storm system
This was not an isolated cell. The same day produced baseball-sized hail in both Cass County, ND and Ward County, ND, along with golf ball-sized hail in Brown County, SD and quarter-sized hail in Grand Forks County, ND — a regional outbreak spanning a wide corridor of the northern Plains.
Contractor guidance
Local contractor data shows current backlogs of 2 to 4 weeks, which is typical for a moderate-density market absorbing a significant regional event. The intake assessment rates storm chaser risk as moderate following major hail, consistent with Bismarck's pattern of drawing out-of-area contractors when local capacity is stretched. North Dakota does not require a state-issued roofing license, so the burden falls entirely on the homeowner: verify a valid general contractor or construction license if your municipality requires one, and ask for proof of liability insurance, workers' comp, and a physical North Dakota business address before signing anything. Under North Dakota law, any contractor who offers to waive or absorb your deductible is committing insurance fraud — walk away.
Permits & building code
At 4 inches, full roof replacement is the more likely outcome than repair on most shingle types. The contractor pulls the permit in Bismarck, inspection is required, and permit costs run $150 to $350. Class 4 impact-resistant shingles qualify for a 10–20% discount with most North Dakota insurers.
