Ice dams in Connecticut are a new problem for homeowners. The cause are the snow totals. Snows that reach accumulations of one to two feet and more and with temperatures that stay under the freezing mark help promote freeze / thaw cycles that lead to ice dams. Gutters are often blamed for ice dams, while they help the build up to a degree they are not responsible for the ice dams. Ventilation or lack of on the eaves or gutter line of your home is the problem. As heat escapes your home mostly above windows and doors warm air meets the cool air under your roofs deck or plywood. This starts the freeze / thaw cycle and grows the ice dams. For some folks when the water from the melting snow can't go down your roof past the ice dam, it goes up your roof under your shingles and in some cases into your home. All homes are different in construction and all handle this a different way. If you have experienced ice dams in the past your ventilation should be looked at and / or you may elect to install heat cables on your roof line and in your gutter system to keep everything running smoothly.
