Many homeowners deal with ice dams in the winter. These chunks of ice accumulate along the lower edges of the roofline when temperatures drop below freezing levels. Luckily, an insulation contractor will help you avoid the problems this buildup poses. Learn more about this issue in this overview to prepare your property for the colder weather.

What to Know About Ice Dams

When snow builds up on the roof, the heat from inside your home melts it. This water runs down to the gutter system, as it’s supposed to. However, the edge of the roof is often colder than its center since it doesn’t get as much thermal transfer from the home’s interior.

If the roof’s edge is below 32 degrees, the water will freeze as it reaches the gutters. Over time, the ice buildup in the gutters could damage the system, making it break off or pull away from the home.

How to Prepare Your House for the Winter

The change in temperature between the upper level and lower edge of the roof is caused by inadequate insulation. Prevent ice dams from forming by scheduling an attic inspection in the fall. If needed, an insulation contractor might use fiberglass or blown-in cellulose to fill the small gaps around rafters and joists and prevent thermal transfer with the roof. How much insulation your home needs depends on your location.

Ventilation also keeps the attic’s interior cooler, which in turn cools the roof center. When placed around the attic, vents safely funnel out the warmer air while bringing in cool air in the winter. The home should have one square foot of vent for every 300 square feet of floor space. Generally speaking, most homes require vents under every other soffit for continuous airflow.
