Ice dams are a problem on roofs in winter, especially in snowy, freezing areas. Knowing how they grow, their effect on your roof, and how to manage them can save repair costs and keep your home cozy and safe in winter.
Make sure your roof is secure with proper ventilation and address any issues so that it can do its job and protect your home.
Ice Dam Creation
Ice dams are born when roof snow melts, runs down, and refreezes into a ice strip at the roof’s end. This happens when heat leaves your home, goes to the attic, warms the roof, and melts the snow.
The melted snow faces colder air at the roof end, refreezes, becoming an ice dam. The cause is mainly uneven roof temperatures, typically from not enough attic insulation and bad roof ventilation.
Damaging Effects of Ice Dams
Ice dam creation can lead to hefty damage:
1. Water Damage: Ice dams blocking drain paths for melted snow can make water slip under roof shingles, causing leaks, decay, and mold in your attic and room walls.
2. Structural Damage: Ice dam weight can press on gutters and roof frames, making them bend or crack.
3. Insulation Damage: Water may dampen and worsen attic insulation, dipping its usefulness and upping warmth costs.
Stopping Ice Dams
Stopping ice dams is crucial:
1. Boost Attic Insulation: Better you attic insulation to limit warmth falling out through your roof.
2. Boost Air Flow: Make sure your attic lets enough air in. This keeps the roof at an even temperature.
3. Block Air Gaps: Seal up any holes around attic floors (like where light fixtures are). This stops warm air from getting into the attic.
4. Add Heat Cords to Roof and Gutters: These wires help melt snow and ice, which stops ice dams from forming.
Dealing with Current Ice Dams
If an ice dam is already there:
1. Get a Roof Rake: Gently get rid of snow at the edge of the roof. This fights more ice from forming.
2. Use Calcium Chloride: Spread calcium chloride (not regular salt) to melt the ice. But watch out! It can hurt plants and other things because it’s strong.
3. Call the Pros: If a big ice dam forms, ask roof experts for help. They know what to do and have the right tools. They also know how to get rid of ice dams without hurting your roof.
Final Thoughts
Ice dams can bother you, but with the right info and by taking steps ahead of time, you can keep your roof safe. Keeping up with roof care, making insulation better, and having good attic air flow will help fight ice dams the best. And don’t forget, if you’re not sure what to do, talking to a pro is always smart. They can make sure your home stays safe and sound.
