Why do ice dams form on Glencoe roofs and can an inspection spot the risk?

Ice dams are a classic Minnesota winter problem, and Glencoe's long, cold, snowy season makes them common. They form when heat escaping into the attic melts snow on the upper roof; the meltwater runs down to the cold eaves, refreezes, and builds a ridge of ice that backs water up under the shingles and into the home. The root causes are usually inadequate attic insulation, air leaks from the living space, and poor attic ventilation, all of which an inspection evaluates. We check insulation depth and coverage, look for ventilation at soffits and ridge, and watch for telltale staining at ceilings and on eaves that signals past ice dam leaks. Older downtown homes with shallow eaves and original insulation are especially prone. Catching these weaknesses before winter lets you add insulation, seal attic bypasses, and improve airflow.
