Montague, CA Hail Storm – July 2025

Montague, CA saw a concluded hail storm on July 8, 2025, with a maximum confirmed hail size of 1 inch. The storm produced three radar-confirmed hail alerts through the early evening.

What Happened

The first alert came at 6:16 PM PDT, with dual-polarization radar supporting 1-inch hail. A second alert followed at 7:23 PM PDT with the same hail size and radar confidence. The final alert arrived at 8:13 PM PDT and again verified 1-inch hail.

The sequence shows a repeated hail signal across multiple zones during the evening storm cycle. All three alerts were tied to the same date and location profile for Montague, CA. The event is no longer active.

Damage Assessment

A 1-inch hail report places the event in the range where shingles, vents, soft metals, and exposed trim often take visible impact. Vehicles parked outside can show dents, cracked trim, or broken lenses. Screens, skylights, and roof accessories can also take direct strikes.

The field pattern should be checked by zone, not by city name alone. Hail of this size can affect one roof section and leave another nearby surface with only light marking. Contractors should expect mixed conditions within the same windward side, especially where trees, slope, or building layout changed exposure.

In post-storm inspections, look first for impact marks on roof ridges, slope transitions, downspouts, window wraps, and north- or west-facing surfaces if the storm path crossed during daylight. Photograph granule loss, split seals, and fresh metal dings before cleanup begins. If a structure has older asphalt, the impact pattern may show up more clearly around hips, valleys, and soft accessory metals than on broad field shingles.

What Contractors Should Know

Start with a roof-level walk that separates hail impact from older wear. On a 1-inch event, the most useful indicators are concentrated strikes on ridge caps, vents, gutters, and collateral surfaces. Check for bruising on asphalt, fractured plastic components, and dent spacing that matches a discrete hail burst rather than scattered aging.

Work the adjacent property set at the same time. Vehicles, patio covers, HVAC fins, fencing, and painted trim often preserve the clearest record of what the storm did. Ask for time-stamped photos from the first day after the event. That helps separate new loss from pre-existing damage and keeps inspection notes aligned with the actual storm window.

On multi-zone reports like this one, document each address by visible condition rather than assuming uniform damage across the warning area. Pay attention to roof material, slope angle, and exposure direction. Those details often determine whether the same hail size produces cosmetic marks, functional damage, or little visible effect.
