San Simon, AZ Hail Storm – September 2025

San Simon, AZ saw a concluded severe hail event on September 13, 2025, with a maximum confirmed hail size of 1 inch. The storm produced a single NWS alert area over the community during the early afternoon.

What Happened

The alert was issued at 12:44 PM MST, or 19:44 UTC, with dual-polarization radar showing confidence in 1-inch hail. The event remained limited to one warning period in the San Simon area.

The storm moved through after midday. Radar support pointed to a narrow hail core rather than a broad hail-producing system. No additional alerts were issued for this same zone after the first bulletin.

The local severe thunderstorm warning covered the general storm path across San Simon and nearby areas. The confirmed hail size reached 1 inch, which places this event at the threshold for severe hail criteria.

Damage Assessment

Hail at 1 inch can break windshield glass, dent vehicle roofs and hoods, and leave visible strikes on softer exterior materials. Roof impact is usually uneven, with losses concentrated where exposure was direct and roof age or condition was already weak.

Metal vents, skylight covers, AC fins, and gutters can show impact even when shingle loss is limited. Painted surfaces may show small circular dents. Vinyl siding and fence panels can also take scattered marks if the hail core crossed the property directly.

For contractors, this kind of event often produces a mixed field. One block can show light cosmetic damage while another shows concentrated impact on roof slopes, garage doors, and parked vehicles. The 1-inch size is enough to justify close inspections on slopes that faced the storm track and on elevations with fewer obstructions.

Documentation should stay specific. Record the impacted surfaces, the direction of travel, and the density of marks by elevation. Photos should include wide shots of the roof plane, then close views of bruised or fractured points. Use consistent scale references when measuring impact marks, and separate hail strikes from pre-existing wear.

What Contractors Should Know

San Simon sits in a part of southeastern Arizona where hail can be isolated and short-lived. In single-zone events like this, a narrow inspection window often matters more than broad area assumptions. Start with the addresses closest to the warning path, then expand outward only if field evidence supports a wider hail swath.

Look first at steep slopes, ridge caps, soft metals, and flat fixtures that collect direct impact. On residential work, check window screens, roof accessories, and detached structures before moving to full roof documentation. On commercial work, inspect HVAC fins, membrane edges, and exposed flashing. Properties with newer roofs may still show accessory damage even when the field does not show widespread failure.
