What is Ice Damming? The buildup of ice and water at the eaves of a sloped roof. Melting snow on the roof refreezes at the roof overhang, causing the damming. Buildings with inadequate attic insulation or ventilation or with large roof projections beyond the exterior walls are more pronto to ice damming.

What causes an ice dam?
Ice dams are formed when the indoor heating rises through the ceiling, up into the attic and warms the roof surface cause the snow to turn to a liquid.
How do ice dams form?
Snow on the heated part of the roof melts and flows down until it meets the part of the roof that is below 32 degrees. At that point, the water freezes into an ice dam.

How do ice dams lead to water damage?
Water backs up behind the dam and, as it sits on the roof, works its way under the roof covering and flows into the attic. From there it can seep through insulation, ceilings, walls and other areas where it can cause damage.
How do you prevent an ice dam?
Keeping consistent attic temperature can help prevent ice dams. Insulation and ventilation are key components of maintaining the proper conditions in the attic and on the roof deck.
