Ice Damming
Ice dams are the build-up of ice at the eaves and valleys of roofs, and in some winter season produce substantial issues. Inadequate attic insulation or attic ventilation can trigger roof snow to melt and move down to the eaves, where the roof location is cooler and the melting snow adheres the roof. Subsequent melting triggers water to swimming pool behind this dam and often the water leaks in between the shingle layers, moistening the roof deck and perhaps the walls and ceilings kept in mind listed below.
