Top 30 counties by total roofing-relevant event count. Hail size in inches diameter (NOAA Storm Events Database measurement standard). Wind speed in mph (sustained or gust, whichever is reported). For commercial roof insurance documentation we recommend cross-referencing the specific event date and county against the underlying NOAA dataset.

Source: NOAA Storm Events Database maintained by NOAA's National Centers for Environmental Information (NCEI). This is the authoritative public-domain dataset for severe weather events in the United States.
Time period: January 2021 through April 2026 (last NOAA update April 21, 2026). 2026 figures are partial — the dataset receives monthly updates and counts will increase as the year progresses.
Event filter: We extracted events where the event type is one of: Hail, Thunderstorm Wind, Tornado, Hurricane (including Typhoon), Tropical Storm, High Wind, or Strong Wind. These are the event categories that produce documented commercial roof damage requiring inspection or repair. Categories like Drought, Flood, and Lightning are excluded from this view because they don't typically cause commercial roof membrane or structural damage in the way wind/hail events do.
Geographic scope: This page covers all 70 South Carolina counties with at least one filtered event in the period. Total: 3,572 events. The underlying NOAA dataset has additional event categories and pre-2021 records available at the source URL above.
Magnitude convention: Hail is reported in inches diameter. Wind is reported in mph (sustained or gust). NOAA records the maximum reported per event. For commercial roofing impact: hail above 1.0″ commonly damages aged single-ply membranes; hail above 1.5″ damages most commercial roof systems including newer membranes. Wind above 60 mph commonly fails perimeter attachment on mechanically-attached single-ply systems.
We respond to commercial roof storm damage across all 70 South Carolina counties. Adjuster-ready insurance documentation. Drone imagery, infrared moisture survey, detailed scope of work for carrier review. 24/7 emergency response.
