What causes ice dams?

Ice dams form when inadequate attic insulation allows warm air to escape through ceilings, heating roof surfaces that melt snow. Melted water flows down to cold roof edges where it refreezes, creating ice barriers that trap subsequent meltwater. Poor ventilation and insufficient insulation are the primary causes of ice dam formation.
