Absolutely. Ice dams can cause extensive damage and costly repairs if ignored, not to mention the time and headaches involved! Once an ice dam is formed and snow and ice melt continues to pool up, it will eventually make its way under your shingles or other roofing materials and lead to water damage amongst interior ceilings, walls, and insulation. The costs associated with fixing these problems far exceeds the cost to prevent them from happening in the first place by having the ice dam removed immediately - not to mention avoiding potential health hazards such as mold buildup and formation.
