Ice dams form on the roofs of buildings after snowstorms. They occur when the temperature of the roof warms up, melts the snow, and then causes water to trickle down towards the gutters. Once the water reaches the gutters, it refreezes and forms ice. The ice then weighs down the gutter and may cause damage, such as a broken gutter, sagging roof, or roof leak. Valley Insulation discusses how cellulose insulation prevents costly ice dams on your roof.
1. Prevents Heat Transfer
Cellulose insulation in your attic forms a thick thermal barrier between the ceiling and the roof. The barrier prevents heat transfer from the warmth of your home to the cold surrounding your roof. The advantage of cellulose insulation in your attic is that technicians can add the insulation until it reaches the optimal level, often up to 2 feet thick. The material spreads out easily and evenly for the best results. This type of home insulation regulates temperatures in the attic, thereby preventing the snow from melting.

2. Seals Gaps
Sealing any gaps in your attic floor is just as crucial as cellulose insulation itself. Air can still seep up from your home into the attic because warm air rises. Once that warmer air hits the roof, it could start to melt the snow. Make sure you seal any gaps between your ceiling and attic. Do this with caulking or special tape. If your attic has any windows, make sure to seal them with the right kind of heavy-duty caulk. Cellulose insulation then comes into play to prevent heat transfer.
3. Keeps Heat Sources Away From the Attic
You may also have sources of heat in your attic that need attention. Recessed lighting, skylights, vents from exhaust vans, and HVAC ductwork may all radiate heat. Make sure you insulate these items to keep heat out of the attic and prevent snowmelt. The correct amount of cellulose insulation, combined with air sealing and heat source mitigation, keeps the roof’s temperature cold enough to prevent ice dams from forming.
