HIGH STORM RISK  — Meridian's humid subtropical climate delivers punishing roofing conditions year-round. Annual precipitation averages 57 inches, with March alone delivering 6.93 inches, sustaining near-constant moisture exposure that degrades sealants and accelerates wood-deck rot. Record temperatures swing from a high of 107 F to a low of -6 F, though hard freezes are rare; the greater threat is summer UV and heat-driven thermal expansion that splits aging shingles. Spring severe thunderstorm seasons bring hail and tornado risk that can cause sudden catastrophic damage. Winter snowfall averages only 0.6 inches, so snow load is minimal, but wind uplift from seasonal storms remains a persistent concern.
