Richardton, ND Hail Storm – August 2025

Richardton, ND saw a concluded hail storm on 2025-08-05 with a maximum confirmed hail size of 1 inch. Two NWS alerts covered the event across the morning hours.

What Happened

The first alert came at 5:39 AM CDT and carried a 1-inch hail estimate with dual-polarization radar confidence. A second alert followed at 7:17 AM CDT with a 1-inch hail estimate backed by radar and spotter verification.

The storm remained a multi-zone event across the Richardton area. Alert timing placed the main hail window from early morning into mid-morning. Both alerts were issued in the same general storm sequence and each pointed to severe hail potential in the warning area.

The confirmed hail size held at 1 inch. No larger verified stones were listed in the event data for this storm on 2025-08-05.

Damage Assessment

One-inch hail is enough to break softer roofing materials, dent gutters, mark siding, and leave visible impacts on vehicles. It can also strip leaves and bruise crops where exposure was direct.

For roofing crews, the first pass should focus on slope direction, ridge lines, soft metal, pipe boots, vents, skylight frames, and starter strip edges. Shingle loss is not guaranteed at this size, but bruising and surface loss can still appear on older asphalt roofs, especially where material was already brittle or wind uplifted.

Metal panels and fascia can show dings that are easier to spot in side light. Vinyl siding and window screens often need close inspection near the exposed faces of the structure. On vehicles, 1-inch hail can produce visible body damage, particularly on hoods, roof panels, and mirrors.

For insurers and adjusters, a 1-inch hail event usually justifies a full exterior walkaround. Document each elevation separately. Note slope, impact density, and any parts of the property that face the storm path.

What Contractors Should Know

Start with the roofs that have the clearest exposure and the oldest materials. In Richardton, the morning timing matters for moisture, glare, and surface conditions. Early inspections should account for wet decking, slick shingles, and limited visibility on north-facing slopes after dawn.

Use a systematic exterior sequence. Check impact soft metals first, then vents, shingles, siding, and openings. On steeper roofs, verify granule loss, fractured tabs, lifted edges, and creased shingles. On metal and composite systems, look for point impacts and fastener-area deformation. If the property includes outbuildings, inspect them separately. They often show cleaner impact patterns than the main residence.

Document every verified impact with location, slope, and material type. Keep the field notes tied to the timing of the alerts. The 5:39 AM CDT and 7:17 AM CDT alerts bracket the main hail period for this event.
