A Guide to Ice Dams | Koala Insulation of Grand Rapids

Icicles hanging from the edges of your roof can make a pleasant winter scene, but they indicate a major structural issue. Also known as ice dams, this common problem can negatively impact many areas of your home, including the roof. In many instances, they form due to insufficient attic insulation. This guide explains a few key basics to help you avoid these common winter problems.

What Are Ice Dams?

During winter, snow and ice accumulate on the roof after bad storms and freezing temperatures. Unfortunately, without adequate insulation, the snow will melt and run down the surface's slope until it meets the edge.

Because the roof edge is often cooler than the middle section, water will freeze upon reaching it, creating an ice dam. This issue often results from heat within the house escaping past the ceiling insulation and heating the roof.

What Kind of Damage Can They Cause?

Ice dams contribute to leaks, as they trap water on the roof and prevent it from flowing through the gutters. As the liquid lingers on the asphalt shingles, the pieces will wear out faster.

Ice dams can also harm gutters. That's because the weight of the ice will pull on the channels and cause the fasteners to become loose. Increased weight can also damage the eaves, which are the overhanging edges of the structure. 

What Can You Do to Prevent Them?

Boosting insulation within the attic helps avoid ice dam formation. Adding insulation to the attic floor keeps the heat inside the house which blocks heat on the lower floors of the home from rising upward and reaching the roof. You'll also want to make sure that you have adequate ventilation to bring cold outside air into the attic and keep the space cool.
