Water backs up behind an ice dam, and it can leak into a home causing damage to walls, ceilings, insulation, and other areas. In addition, moisture entering the home from ice dams can lead to the growth of mold and mildew.
Often homeowners aren’t aware of any problems until the snow really starts to melt in the spring. Taking care of ice dams while it’s still cold can prevent major problems when it starts to warm up.
An ice dam grows as it is fed by the melting snow above it, but it will limit itself to the portions of the roof that are on the average below 32. The water above backs up behind the ice dam and remains a liquid. This water finds cracks and openings in the exterior roof covering and flows into the attic space. From the attic it could flow into exterior walls or through the ceiling insulation and stain the ceiling finish.
Removing snow from the roof helps, but a “roof rake” and push broom may damage the roofing materials. And any person on the roof during the winter or performing work on the roof from below is risking injury and risking damage to the roof and house.
SMC recently purchased new and efficient steam equipment to help their customers. Contact SMC Construction today at (763) 300-5519 to schedule removal of your ice dams and prevent bigger problems later.
