Unless you live in a barn there is barely a home in New England that doesn’t have ice dams on its roof. How are ice dams formed? Ice dams are formed when heat from inside the house escapes through the insulation and radiates through to the underside of the roof deck and melts the snow pack on the roof. When the snow melts it flows down and freezes when it hits the cold edge of the house (at the gutter) forming an ice dam. This is why unheated barns do not have ice dams.
Beyond Ice Dams there is also a danger of Roof Collapse under the weight of the snow.
What is the best way to prevent Ice Dams and Roof Collapse?
Remove the snow from the roof. Without a snow pack to melt there can be no ice dam and likewise there will be no danger of your roof caving in under the stress.
