Nogales, AZ Hail Storm – July 2025

Nogales, AZ saw a concluded hail event on July 8, 2025, with verified hail up to 1 inch. The storm crossed the metro area during the afternoon and produced a single NWS alert area.

What Happened

The storm reached Nogales during the afternoon and was tied to one severe thunderstorm alert issued at 3:33 PM MST. The alert called for 1-inch hail and matched dual-polarization radar hail detection confidence in the NEXRAD data.

No additional alert areas were issued for this storm. The event remained a single-zone hail report across the Nogales metro.

Damage Assessment

Hail at 1 inch is large enough to break or chip exposed windows, dent soft metal roofs, and mark vehicle panels. It can also damage vents, trim, skylights, and rooftop accessories that take a direct hit.

Roof outcomes vary by material and slope. Asphalt shingles can lose granules and show bruising. Tile roofs can crack at impact points, especially on ridges, edges, and older or weathered sections. Metal roofing often shows visible dents, while membranes and low-slope systems can take punctures if impacts concentrate in one area.

The hail size reported here is not a broad estimate. It was verified in the storm record at 1 inch, which places the event in a range where exterior checks are warranted after the storm clears.

What Contractors Should Know

Field crews should start with the highest exposure surfaces first. Check roof slopes, soft metal flashing, vents, gutters, condensers, and window screens before moving to cosmetic items. In Nogales, attention should stay on north, west, and elevated faces where direct hail impacts can leave the clearest marks.

Use a systematic walkaround and document each elevation separately. Photograph impact points, cracked tiles, dented accessories, and any collateral damage on cars, patio covers, and fencing. If the roof is steep or fragile, inspect from safe access points and note conditions before close contact. One-inch hail can leave isolated damage that is easy to miss without a controlled review.

For contractors building a lead pack, focus on the roofs and structures inside the alert area rather than the full metro footprint. The storm was limited to one event window, which keeps canvass work tighter and easier to sort by street-level exposure. Look for properties with older roofing, recent repairs, or mixed exterior materials where impact patterns are more visible.

If you are matching jobs to storm timing, use the afternoon alert window as the field anchor. Signs of fresh impact should line up with the verified hail period, including denting on metal components, broken screens, and bruised shingle fields. Where tile or membrane damage is present, document the exact slope and face before any cleanup starts.
