Valleys generally are large hazard parts. They obtain significant volumes of drinking water and also small quantities of ice in a valley can pressure h2o sideways and below roofing elements. This really is also why valleys are so effortlessly harmed for the duration of poor ice removal.

As far more snow melts, water swimming pools driving the ice dam, possibly seeping under the shingles and into the house.

Understanding these components aids in both dealing with and preventing long run ice dam problems.
Avoidance begins Within the household. Restricting warmth decline into your attic is among the best ways to reduce ice dam development. Sealing gaps all around attic entry details, exhaust admirers, light-weight fixtures and ductwork allows continue to keep warm air where it belongs.
