Remember what this winter looked like? We had close to 6 feet of snow this year. There were several homes where we had to remove vast amounts of snow from the roofs prior to warmer weather. This helped eliminate the potential for water damage caused by ice dams.
Ice dams and broken pipes were just some of the issues we faced this past winter. Snow was excessive, cold temps below zero as well (many days back-to-back). All this created conditions where snow on roofs melted, and ran back under the shingles. Once under the shingles, water goes into to the attic, soaks the insulation, and causes damage to interior ceilings, some minor and some more serious.
