How Minnesota's Climate Affects Your Roof
Minnesota roofs work hard year-round. Winter brings snow loads, ice dams, and freeze-thaw cycles that pry shingles loose, while summer storms bring hail and wind. Minnesota's building code typically requires ice-and-water shield in the bottom 24 inches of eaves, proper attic ventilation to prevent ice dams, and snow-load engineering on heavier accumulation areas. A well-insulated, properly ventilated roof system can prevent the majority of winter damage.
