What causes ice dams on Marshall homes and how do you spot the risk?

Ice dams form during southwest Minnesota winters when heat escaping into the attic melts snow on the roof, the water runs down to the cold eave, and it refreezes into a ridge of ice that backs water up under the shingles. Marshall's long, cold winters and heavy snow loads make this a recurring problem, and the damage shows up as stained ceilings, peeling paint, and hidden moisture in walls. The root causes are usually poor attic insulation, air leaks from the living space, and inadequate roof ventilation rather than the roof itself. During the inspection we evaluate attic insulation depth, ventilation, and signs of past ice-dam leakage at the eaves and ceilings, so you know whether the home is prone to it. Fixing insulation and ventilation is often more cost-effective than repeated roof repairs.
