You may have noticed long icicles hanging from your gutters and not realize the significance of the damage that may be occurring behind them.
April 15, 2006 (Press Release) --
An ice dam is a wall of ice that forms at the edge of the roof, usually at the gutters or soffit. When it forms the water then backs up behind the ice dam and creates a pool of water. This pool of water can leak into your home and cause damage to walls, ceilings, insulation, and other areas
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 soffit's, 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.
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.
How can I prevent ice dams in the future?
Properly ventilating and insulating the attic is usually the best way to prevent ice dams. The usual recommendation for proper ventilation is 1 square foot of vent for every 150 feet of attic floor area but each climate region may have it's own recommendations so I would suggest contacting a licensed local insulation company near you. If you have small louvered vents at either end of the attic known as gable vents you can either replace them with larger vents, or install an electric vent fan over the inside of them. These special fans usually work on a thermostat and will pull outside air into the attic to keep the temperature inside consistent.
