How Air Sealing Can Prevent Ice Dam Formation

Drafty rooms, high energy bills, fluctuating temperatures, and most of all, ice dams can make your home a good candidate for air sealing. But what is air sealing, and how does it prevent hazardous ice dam formation? Keep reading to find out.

What Is Air Sealing?

Designed to block warm air from escaping into the attic, air sealing is a cost-effective way to reduce heating and cooling costs, increase interior comfort and prevent the formation of ice dams on your roof. When combined with proper insulation, air-sealing techniques, like weatherstripping and caulking, will help keep your attic’s temperature cooler, causing less heat to leak through your roof.

How Can Air Sealing Prevent Ice Dams?

Ice dams are ridges of ice that can form along the eaves of your roof during the winter months. After a snowfall, the heat escaping from your roof can cause the snow to melt. As the water attempts to drain, it will refreeze along your roof’s edge where the temperature is suitable for ice formation. Once the ice dam has taken shape, snow melt will back up behind the ridge and can leak into your home, causing damage to walls, ceilings, insulation and other areas.

By air sealing your attic, your roof will maintain an even, cool temperature, helping prevent snow melt during days and nights where the outside temperature is below freezing. As a result, properly air sealing and insulating your attic can thwart ice dams before they can cause any damage.
