HIGH STORM RISK  — Kearney sits in central Nebraska's High Plains corridor, where roofs absorb punishment from three directions. Summers push past 100 F -- the record high is 114 F -- while winters bite to a record low of -30 F, a swing that cycles shingles through aggressive freeze-thaw expansion. Average annual snowfall of 21.8 inches adds sustained snow load stress, and Great Plains hail and wind events are a seasonal constant. UV degradation is accelerated by the region's high sun exposure and dry air, shortening asphalt shingle lifespans compared to more humid markets. Roofs here must handle thermal shock, snow load, and periodic hail impact in the same year.
