Ice dams can cause serious damage to your roof, gutters, and even the inside of your home. They form when snow melts on a warm roof and refreezes near the colder eaves, creating a ridge of ice that traps melting water. Here’s how to prevent them before winter hits hard:
- Improve Attic Insulation – Make sure your attic is well-insulated to keep warm air from escaping through the roof. This helps maintain a consistent temperature and prevents snow from melting unevenly.
- Seal Air Leaks – Check for gaps around chimneys, vents, and light fixtures where warm air can leak into the attic. Seal them with caulk or spray foam.
- Ensure Proper Ventilation – A well-ventilated attic keeps cold air circulating and maintains a uniform roof temperature. Ridge and soffit vents work well together for steady airflow.
- Clean Gutters and Downspouts – Clogged gutters prevent melted snow from draining properly, increasing the risk of ice buildup. Clear leaves and debris before the first snowfall.
- Use a Roof Rake – After heavy snow, safely remove excess snow from the roof’s edge using a roof rake. This reduces the amount of melting snow that can refreeze.
Taking these steps now can save you from costly repairs later — and help your roof weather the winter safely.
