Circle, MT Hail Storm – July 2025

Circle, MT was hit by a concluded hail storm on July 19, 2025, with verified hail up to 1 inch. The event unfolded in the morning and produced a narrow hail swath across the local warning area.

What Happened

A single severe thunderstorm alert covered this storm at 6:50 AM MDT on July 19, 2025. The alert called for 1-inch hail and used dual-polarization radar confidence. No additional alerts were issued for this event.

The hail threat was brief and localized. Radar support came from a single warning polygon tied to the Circle area, with the storm already concluded by the time the public event record closed. The timing points to an early-morning hail episode rather than a longer-lived afternoon line.

Damage Assessment

Hail at 1 inch can leave visible impact on vehicles, siding, trim, vents, skylights, and soft roofing materials. In a single-zone storm like this one, damage is often uneven. One block can show clear impact while the next shows little or none.

Crews should expect roof marks that are easier to find on south- and west-facing slopes if the storm moved across the area with sun exposure afterward. Asphalt shingles may show bruising or granule loss without obvious surface failure. Metal components can show denting even when the roof covering appears intact. Window screens, exposed HVAC fins, and gutters can also carry the first visible signs.

For field work, treat this as a small but credible hail event. A 1-inch report is enough to justify close roof and exterior checks, especially on older properties or homes with previous weather wear. The damage pattern may be isolated to one side of a structure or one stretch of a subdivision.

What Contractors Should Know

Start with roofs, then work outward. In Circle, a morning hail event can leave a mix of wet surfaces and dry edges by the time inspections begin. That can make fresh impact marks easier to document on shingles, flashing, and soft metals. Photograph roof planes separately and log slope, elevation, and face direction. Keep notes on test squares where bruising is present without full material loss.

Ground-level inspection still matters. Check fence tops, AC condenser fins, downspouts, gutters, porch screens, and vehicle panels parked in the open. On a 1-inch event, the most efficient leads usually come from properties with exposed additions, older roofing, or multiple light-metal features. Tight canvassing works better than broad neighborhood assumptions.

Estimate should stay tied to observed conditions. Do not assume a full-roof claim from one confirmed hail size. Verify roof impacts, then compare to exterior metal strikes and accessory damage. If the roof field is clean but the soft metals are marked, document that split clearly in the inspection packet.
