Anderson, SC Hail Storm – May 2025

Anderson, SC saw a concluded hail storm on May 16, 2025, with verified hail up to 1 inch across the warning area. The severe thunderstorm alert came in at 10:39 PM EDT and was supported by radar and spotter confirmation.

What Happened

The storm moved through Anderson late in the evening. NWS alert coverage for this event included one severe thunderstorm warning, issued at 10:39 PM EDT and tied to 1-inch hail.

Radar and spotter data both supported the hail report. The confidence on the alert was listed as radar plus spotter verified. No additional alerts were issued for this storm in the event set.

The hail report places the event in the range that can affect roofs, siding, vents, gutters, and soft metals. The storm was limited to a single zone in the Anderson metro area, with the public warning area covering the broader path of the system.

Damage Assessment

One-inch hail can leave visible impact marks on asphalt shingles, aluminum trim, screens, and vehicle surfaces. On newer roofs, the field signs can be subtle from the ground. On older roofs, the same hail size can expose existing wear, lift tabs, or loosen granules.

In Anderson, the event profile points to a localized hail swath rather than widespread wind damage. That keeps field checks focused. Contractors should expect spot damage patterns instead of uniform loss across every structure in the warning area.

Driveways, patios, siding, and window wrapping can also show strike marks. Crews should look for collateral hits on soft metal components, because those often present clear field evidence even when roof damage is light. When hail reaches 1 inch, the inspection file should include photos of roof planes, gutters, downspouts, AC fins, window screens, and any marked vehicles in the storm path.

For insurance work, the key distinction is between reported hail in the warning area and actual roof-level impact. A broad alert does not define the precise strike line. Field inspection still needs roof slope notes, elevation context, and consistent photo coverage from the ground and the roof.

What Contractors Should Know

Start with the addresses closest to the reported hail path, then move outward. Late-evening storms often leave little direct visual evidence for homeowners, especially after dark, so early call-backs can help secure undisturbed conditions. Ask for the time of impact, where the vehicles were parked, and whether any skylights, soft metals, or screens show fresh marks.

Use a repeatable inspection sequence. Check the full roof perimeter first, then ridge caps, vents, valleys, and flashing. Match ground photos with roof photos so the file shows the same strike patterns from both angles. If the home has attic access, look for daylight at penetrations and note any displaced components before cleanup begins.
