Ice dams form when heat escapes into the attic and warms the roof. Fix the heat loss and you fix the dams. We can connect you with local contractors who help with insulation, air sealing, and ventilation.
Dams are a symptom of a warm roof. The long-term fix is to keep the roof deck cold so snow doesn't melt from underneath. That means addressing three things together.
Thin or settled insulation lets heat from living spaces reach the roof deck, warming it and melting snow from underneath.
Gaps around chimneys, plumbing stacks, attic hatches, and recessed lights let warm, moist air pour into the attic.
Without enough intake and exhaust ventilation, the attic can't stay cold and even — warm spots melt snow unevenly.
Roof raking is a short-term help; insulation, air sealing, and ventilation are the permanent fix. We can connect you with local contractors who handle that work.
Prevention stops future dams, but an existing dam still needs to be removed so water can drain. Steam is the safe method.
