HIGH STORM RISK  — Longview endures a wide thermal range for East Texas -- the all-time record high is 113 F and the record low is -5 F -- while averaging 48.18 inches of annual precipitation, one of the wetter readings in the state. That heavy rainfall, combined with frequent hail days and Gulf-tracking thunderstorm corridors, subjects roofs to frequent impact damage and moisture infiltration. January overnight lows averaging 34.3 F push roofing materials through repeated freeze-thaw stress. Minimal annual snowfall of 0.7 inches means ice accumulation is rare but not impossible, and any ice event on undertreated low-slope roofs can cause serious damage.
