Evidence / storm surfaces
How Summerville saw the hail — from two instruments
Two instruments, one storm: NEXRAD logs the point signatures it detected overhead, while the estimated-size surface models how large the hail aloft could have grown. Agreement between them is not guaranteed — the gaps are where the model ran ahead of, or behind, the detections.
Estimated size field Radar-estimated maximum hail size across the swath, modeled from radar aloft. It reflects the biggest stone the storm could support, which may differ from what actually fell.
Only the radar-estimated size surface resolved for Sep 6, 2026 — this storm produced no NEXRAD point detections over Summerville, so there is one map to show, not two.
The storm in context
Where Sep 6, 2026 sits in Summerville's hail record.
This was Summerville's 9th recorded hail day, arriving 15 days after the Aug 22, 2026 storm. By severity it ranks 1st of the 9 storms we have logged here. Radar put the day's largest stone over Summerville at 1.25" — radar-estimated size aloft.
The Sep 6, 2026 convective day was bigger than Summerville: the same system put hail over 608 other tracked cities, 44 of them in South Carolina. Nearest: Moncks Corner (7 miles northeast, up to 1.25"); Ridgeville (12 miles west, up to 0.5"); Cross (15 miles northwest, up to 0.75").

Storm forensics
How the storm moved
Read from the arrival times and locations of the NOAA ground reports, not a radar-measured storm track.
Reports came from Sangaree — beyond Summerville itself.
Damage-capable hail signal
What 1.25" hail means for Summerville roofs.
Quarter-size and larger hail can bruise asphalt mats, remove granules, and dent exposed soft metal. The mapped footprint identifies an inspection priority area — it does not identify which individual roofs, if any, sustained damage.

Roofing exposure
What this storm is worth to a roofer.
Potential roof exposure
$138M
Potential roof exposure — 11,520 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs
- 58 jobs
- Illustrative work
- ~$870K
Close just 0.5% of the 11,520 homes in this footprint at the average $15,000 roof job. Illustrative math, not a projection — your results depend on your outreach and how the market responds.
Claim window
September 2028
Claims from this storm can typically be filed until around September 2028 — the window to reach these homeowners while it's still open. Deadlines vary by policy and state.
Names and phones for every home in the footprint: at most $2,419 on top of the $150 plan.
