Common Problem: Roof Icicles

Icicles are caused by a process known as ice damming, commonly found on the drip edge of homes and other buildings. This occurs when there is enough heat escaping through the roof to cause the snow that is on the roof to melt into water and run down the roof only to freeze at the unheated section known as the drip edge. The more heat leaving the home through the roof deck, the worse the ice dams get. This is a sign of a poorly insulated attic. The ice can even curl the shingles up and get underneath the shingle. When that ice melts, it goes directly into the home in most cases, ruining sheet rock, blistering paint, and causing mold problems with the framing of the home.

When the ice melts, it goes directly into the home, ruining sheet rock, blistering paint, and causing mold problems with the framing of the home. This process can be stopped by using spray foam insulation to air seal your attic system.

Insul-Tech Solution: Attic Sealing

This process can be stopped by using spray foam insulation to air seal your attic system.

By air sealing the attic, you cut off the thermal exchange between the warm air in your home and the cold air outside. The spray foam also adds structural integrity to the roof to help hold any extra snow that wont be melting off of the roof anymore.
