Historical county exposure only. These figures describe recorded weather, not any specific roof. Do not infer roof condition, remaining life, damage, replacement timing, or a combined score.
Values come from the frozen 2016–2025 Roof Year benchmark: NOAA daily temperature records, NOAA Storm Events reported county-days, and NASA POWER solar exposure. Percentiles use midrank among counties with valid data.
