Ice dams occur when water from melting snow runs down the surface of your roof and refreezes. As the cycle of freezing and melting continues, ice builds up and begins to “dam”. Sometimes the pooled water finds its way under shingles and refreezes, lifting the shingles from the roof deck and creating a spot for water to enter your house.
The Winter of 2015 was one of the worst in history for ice damming. After a slow start the snow began to pile up in February creating a deep and heavy snow pack on the roofs of homes. Perfect conditions for the formation of ice dams.
We are off to a similarly slow start this Winter. While the chances of getting hit with 10 to 12 feet of snow like last year are remote, there is a lot of Winter left. This is the time to take steps to prevent ice dams and to educate ourselves on measures that can be taken to minimize the damage if an ice dam occurs.
Arbella Insurance has produced the following brochure that explains how to prevent ice dams and what to do in the event ice dams occur.
