HIGH STORM RISK  — Conway sits in the humid subtropical zone of central Arkansas, where temperature extremes range from -15 F to 115 F. That wide swing drives severe freeze-thaw cycling through winter months, cracking sealants and widening shingle seams. Annual snowfall averages 2.3 inches, enough to impose periodic ice-dam risk at eaves. Hail-bearing supercell thunderstorms are a recurring spring and fall hazard across central Arkansas, threatening granule loss and sheathing damage. Most notably, an F4 tornado struck Conway on April 10, 1965, killing six people and injuring 200, a reminder that wind uplift forces well above design limits are a real historical precedent for local roof structures.
