Ice Damming
Ice dams are the accumulation of ice at the eaves and valleys of roofs, and in some winter establish substantial concerns. Insufficient attic insulation or attic ventilation can activate roof snow to melt and move down to the eaves, where the roof area is cooler and the melting snow adheres the roof. Subsequent melting sets off water to swimming pool behind this dam and in many cases the water penetrates in between the shingle layers, dampening the roof deck and possibly the ceilings and walls noted below.
