Las Vegas, NV Hail Storm – September 2025

Las Vegas, NV was hit by a concluded hail storm on 2025-09-06, with peak hail of 1.75 inches. The event produced three NWS alerts across the metro area through late evening.

What Happened

The first alert came at 8:57 PM PDT, when dual-polarization radar detected 1.75-inch hail in the warning area. Two later alerts followed at 10:09 PM PDT and 11:38 PM PDT, each tied to 1-inch hail with radar and spotter verification.

The sequence shows a multi-zone storm footprint across the Las Vegas metro. The hail threat did not remain limited to one short-lived cell. It carried through the evening in separate pulses, with the strongest signature at the start of the event and smaller but verified hail later in the night.

Damage Assessment

Hail up to 1.75 inches can break or fracture roof shingles, dent metal flashing, and damage gutters, vents, and soft metal trim. It can also crack skylights and leave visible strikes on vehicle panels, mirrors, and windshield edges.

The 1-inch verified hail later in the event still supports localized exterior damage. Crews should expect scattered roof impacts, bruised siding, and cosmetic vehicle damage in exposed parking areas. The mix of 1.75-inch and 1-inch reports suggests inconsistent impact intensity across the metro, with some properties taking a harder hit than others.

Contractors should treat this as a full inspection event, not a spot check. Check slopes facing the storm path first. Look for lifted shingles, loss of granules at roof edges, dents on gutters and drip edge, and seam damage around roof penetrations. On commercial buildings, inspect HVAC fins, membrane seams, and parapet flashings.

Vehicle lots need a separate walk-through. Document roof dings, hood strikes, mirror damage, and broken glass before cleanup starts. In a multi-zone storm like this, the visible impact can vary block to block, so a narrow drive-by survey is not enough.

What Contractors Should Know

Pull weather records, photos, and timestamps into the job file before canvassing. The first verified hail signal at 8:57 PM PDT gives a clean anchor for the start of the event, and the later alerts at 10:09 PM PDT and 11:38 PM PDT help separate the stronger impact zone from the lower-size follow-on hail. Use that sequence when grouping claims and assigning inspection routes.

Focus initial field work on the areas closest to the strongest radar-derived hail signature. Roofs with steep pitch, older asphalt shingles, and exposed metal components should move to the front of the queue. In the Las Vegas metro, flat and low-slope systems also deserve attention because membrane punctures and seam failures are easy to miss until water intrusion starts.

For residential work, document soft metal damage, shingle bruising, and any broken glazing in the same visit. For commercial work, note rooftop equipment, edge metal, and membrane condition with clear photo sets. Keep the inspection notes tied to the local alert times so adjusters can match property-level findings to the storm timeline.
