Blog | How to Prevent Ice Dams from Forming on Your Roof


Ice dams can cause serious damage to your roof and home. They form when snow on the roof melts and then refreezes at the edges, creating a barrier that traps water. This water can leak into your home, causing problems like mold, damaged ceilings, and ruined insulation. Here are some simple ways to prevent ice dams from forming.

1. Keep Your Attic Cool
Ice dams form when heat from your attic melts the snow on your roof. The best way to prevent this is to keep your attic cool. You can do this by adding proper insulation and ventilation. Make sure your attic stays close to the same temperature as the outside air.

2. Improve Roof Ventilation
Good ventilation allows cold air to enter and warm air to escape. Install ridge vents and soffit vents to improve airflow in your attic. This helps keep your roof cool and prevents snow from melting too quickly.

3. Seal Attic Leaks
Warm air from your home can leak into the attic through small gaps. Check for leaks around lights, vents, and chimneys. Use caulk or spray foam to seal these areas. This will help keep warm air inside your home and prevent ice dams.

4. Clean Gutters and Downspouts
Clogged gutters can trap melted snow, which can refreeze and form ice dams. Clean your gutters before winter to remove leaves and debris. Make sure downspouts are clear so water can drain properly.

5. Remove Snow from the Roof
After a heavy snowfall, use a roof rake to remove snow from the edges of your roof. This helps prevent melting and refreezing. Be careful when doing this, or hire a professional if needed.

6. Use Heat Cables
Heat cables can be installed along the edges of your roof to prevent ice dams. These cables warm the roof and keep snow from freezing. They are especially useful for homes in very cold areas.

7. Check Your Insulation
Adding insulation to your attic helps keep warm air inside your home and out of the attic. This reduces the risk of ice dams. A well-insulated attic can also lower your heating costs.

By following these simple steps, you can prevent ice dams and protect your home from damage during winter. Taking action before snow and ice build up will save you money and stress in the long run. After a major snowstorm, inspect your roof for damage that may require a Tulsa roof replacement. Tulsa's fluctuating temperatures can worsen existing issues over time.
