Golf ball-sized hail detected near Bismarck, ND on September 6, 2026

Damage assessment

The radar-confirmed strike placed the hail core approximately 3 miles southeast of downtown Bismarck, with one report logged in Burleigh County that day. At 1.75 inches, architectural asphalt shingles — the dominant material in Bismarck's housing stock — are at meaningful risk of functional damage: granule loss, cracked tabs, and compromised mat integrity are realistic outcomes at this size, not just cosmetic bruising. Roofs older than 10–12 years or already showing wear are most vulnerable; newer installations may show less structural loss but are unlikely to escape unmarked. Burleigh County has recorded hail as large as 4.5 inches as recently as July 2024, so this event sits well below the county's worst — but 1.75 inches is enough to warrant a professional look.

Historical context

This event ranks 59th out of 150 hail events of 1 inch or greater recorded in the Bismarck area over the past decade — mid-pack by magnitude. The largest on record for Burleigh County was a 4.5-inch event on July 29, 2024, a threshold capable of functional loss on every shingle type. September historically averages about one such event per year in this county, so a storm this month is not unusual but is toward the tail end of the active season.

Storm system

The same system produced 1.25-inch hail in Ward County and 1-inch hail in Grand Forks, pointing to a broader regional convective event rather than an isolated cell over Bismarck.

Contractor guidance

Local contractor data shows current backlogs running 2 to 4 weeks, which is manageable but means delays are real — don't wait if you suspect damage. The intake assessment rates storm chaser risk as moderate, consistent with Bismarck's pattern of drawing out-of-area crews after notable regional events. North Dakota does not issue a statewide roofing license, so verify that any contractor holds a valid municipal general contractor or construction license, carries liability and workers' comp coverage, and can provide a physical North Dakota business address with verifiable local references. Get all three before you sign anything.

Permits & building code

At 1.75 inches, outcomes will range from localized repair to full replacement depending on roof age and pre-storm condition — a professional inspection determines which. The contractor pulls the permit in Bismarck; expect a permit fee of $150 to $350, and a post-installation inspection is required. Class 4 impact-resistant shingles qualify for a 10–20% discount with most North Dakota insurers.
