In Johnston County the roof threat is wind, not hail
What the public record says about roofs in Clayton and the rest of Johnston County
Peak recorded gust
Apr 28, 2016
Roof-relevant events recorded
2016–2026
161 of the 178 roof-relevant events NOAA recorded in Johnston County between 2016 and 2026 were thunderstorm wind. Hail accounts for 13. The strongest gust in the file is 50 kt, measured on Apr 28, 2016. For completeness, the largest hail the county has on record is Ping Pong Ball at 1.50 in, on May 3, 2016 — a single day, not a pattern.
Wind does not damage a roof the way hail does, and it does not damage the same parts of it. Wind works on the edges. Uplift concentrates along the eaves, the rake edges and the ridge, where a shingle's sealant strip is the only thing holding the tab down; once one tab breaks its seal the course above loses its anchor and the failure runs along the line. That is why wind damage tends to appear as a clean run of lifted or missing tabs at a perimeter rather than as scattered marks across the middle of a slope. On a roof in this county the places worth looking at first are the ridge caps, the first two courses above the gutter, the rake edge on the side the weather comes from, and the metal flashing where the roof meets a wall or a chimney.

* 2026 is a partial year — the record runs to the most recent update of the source, not to the end of the year, so its bar is not comparable with the others. A year showing zero had no recorded hail, tornado or thunderstorm-wind event in this county.
