WHAT IS IT?
An ice dam is a ridge of ice that forms at the edge of a roof. It can damage your roof and the interior of your home, as well as your gutters and downspouts.
HOW DO THEY FORM?
Ice dams form when the roof over the attic gets warm enough to melt the layer of snow. The water begins to trickle down between the layer of snow and the shingles until it reaches the eave of the roof. This area stays cold because it extends beyond the side of the house causing the water to re-freeze.
(The flatter the pitch of the roof, the easier it is for an ice dam to form.)
PREVENTING ICE DAMS
BE PROACTIVE! There are steps that can be taken to help prevent future ice dams. Remember, ice dams are primarily caused by poor insulation and ventilation in the space under the roof.
- Have a licensed contractor, like NAC, inspect your roof and attic for proper insulation and ventilation. (NAC offers free inspections – click here to schedule your free inspection today.)
- Seal all points where warm air leaks from the living space into the attic.
- Install adequate attic insulation and make sure attic is properly ventilated.
WHAT CAN I DO IF I SEE SIGNS OF AN ICE DAM?
