Protect Your Home from Ice Dams This Winter

Ice dams are a winter hazard that many homeowners in our region are familiar with. These ice
formations along the edge of the roof can cause serious problems, from leaks to structural
damage. Thankfully, with the right insulation and ventilation, you can prevent these issues and
keep your home safe.

Why Ice Dams Form
Ice dams occur when heat from the attic warms the roof, melting the snow. This water flows
down to the colder edges of the roof and refreezes, forming a dam. As more snow melts, water
backs up behind the dam, potentially leaking into your home and causing damage.

How Insulation Helps Prevent Ice Dams
The key to preventing ice dams is adequate attic insulation. Without enough insulation, heat
escapes from your living space into the attic, warming the roof. Adding or upgrading insulation
can help maintain a uniform roof temperature, reducing the risk of ice dams.

Ventilation and Air Sealing: Essential Steps
Proper attic ventilation is also crucial. When warm air is trapped in the attic, it can accelerate
snow melting on the roof. By sealing air leaks and ensuring good ventilation, you help keep the
roof cold, preventing the conditions that lead to ice dams.

Handling Ice Dams Safely
If you notice an ice dam forming, try using a roof rake to remove snow from the edge of your
roof. However, avoid using tools that might damage the shingles or roofing material. In severe
cases, it’s best to contact a professional to safely remove the ice.
