What Causes Ice Dams?
How Can I Stop Ice Dams?
Ice dams are a thick layer of ice that builds up on the eaves of a roof.
Ice dams begin when warm air rises to the underside of your roof sheathing; (decking); melts the snow and then when temperatures drop, it refreezes. Continual repetition of this thaw and freeze cycle creates ice dams. Often times, there is a gap in the insulation between the baffle and the top of the exterior wall. A combined air leakage into the house through the exterior wall insulation with lack of air ventilation can also facilitate ice dams. They are caused because of issues with ventilation and insulation
Attics need to breathe. Another factor may be at the eaves and ridge venting could be impeded by insulation blocking the air flow across the roof plane.
At A. M. Burney Exteriors, Inc., we look to see if any of these conditions are the cause of ice dams. We also look at the ridge vent design to see if it allows wind driven snow into the attic. The ridge deck needs to be the same temperature as the outside air to prevent snow that accumulates on the roof from melting and refreezing at the eaves.
Missing insulation is very common in both ceilings and walls. Insulation may have been improperly installed, settled over time or shifted. But all can be fixed
If you have ice dams, a good time to address this issue is when you are installing a new roof. We prefer to address these issues before starting any roofing installation.
