Ice dams are most common in northern climates.
They occur when heavy snow buildup melts during the day and then refreezes when temperatures drop overnight. After several days of melting-freezing cycles, melted water and ice can work up under the shingles until water enters the attic and eventually damages ceilings, walls, and personal belongings. The following guidelines will help prevent ice dams from forming. Please contact us if you need help in maintaining your roof this season. This also reduces the chances of roof failure caused by excessive snow weight.
