Ice dams are usually caused by heavy snowfall and improper ventilation in the attic. This causes warmer areas in your attic then the snow begins to melt, even when the outside temperature is well below freezing. When the accumulated snow on your roof starts melting it runs down your roof underneath the snow until it reaches a "colder" section like the soffits, valleys or in gutters then it begins to freeze again, this process of thawing and refreezing is what causes an ice dam. Cleaning the gutters on your home can help prevent ice dams from occurring as quickly but they can still occur if the conditions are right. The gutters will be just as cold as it is outside and in some cases, full of frozen debris. So even if you don't have a soffit for the water to refreeze in, the melted water will most likely refreeze when flowing into the gutters.
How Can I Remove an Existing Ice Dam?
Properly removing an ice dam can be quite dangerous if you don't know how. In the past some members of the media suggested hiring a contractor to pull the gutters off your home so the whole ice dam process would be solved. This suggestion was well intended but wrong. Contractors that started removing gutters caused significant damage to roofing and guttering systems, then when the snow melted it dropped next to the homes foundation and caused the basements to flood.
WARNING! Performing ice dam removal is risking severe personal injury and damage to the roof if not done properly. Never walk on a snow covered roof and make sure if your using a ladder you follow the proper safety procedures. I highly suggest contacting professionals with the proper equipment and roofing experience to carry out this job.
Immediate action: Remove snow and ice dam from the roof this will eliminate the main ingredients necessary for the formation of another ice dam and will usually stop the water from coming in within an hour. Using a roof rake and push broom (not water) remove the snow by carefully pulling it down the slope of the roof line. Never pull snow across the roof or it may break off the shingles and other damages. Then carefully chip away a channel through the ice dam so the water will be able to flow through, just make sure you stop when you get close to the roofing. It's not necessary to remove all of the ice in the gutters or the ice dam itself if you have removed the snow from the roof, it will melt when the temperatures rise.
