Ice Dams Can Wreck Your Roof
Ice Dams: What They Are & How to Prevent Costly Roof Damage

Winter can be tough on homes, and with the recent milder weather, ice dams are becoming a real threat for homeowners. If left unchecked, these icy buildups can lead to costly repairs and serious water damage inside your home. But don’t worry—we’re here to help you understand what ice dams are, how they form, and most importantly, how to prevent or get rid of them.
What Is an Ice Dam?
An ice dam is a ridge of ice that forms at the edge of your roof. It happens when snow melts during the day due to heat escaping from your home and then refreezes at night when temperatures drop. Over time, this ice barrier traps more melting snow behind it, preventing proper drainage. The result? Water backing up under your shingles, leaking into your home, and causing potential damage like:
- Roof leaks
- Insulation damage
- Mold growth
- Stained ceilings and walls

How to Prevent Ice Dams
Prevention is always the best solution when it comes to ice dams. Here are some key steps you can take to protect your home:
- Ensure Proper Insulation & Ventilation – A well-insulated attic helps keep warm air from escaping, reducing the chances of snow melting on your roof. Good ventilation also helps regulate temperature and prevent ice buildup.
- Clear Snow From Your Roof – Using a roof rake, carefully remove excess snow from your roof before it has a chance to melt and refreeze.
- Seal Air Leaks – Check for gaps in your attic, around light fixtures, and near chimneys where heat may be escaping. Sealing these areas can reduce uneven roof temperatures.
- Clean Your Gutters – Make sure your gutters and downspouts are free of debris to allow melted snow to drain properly.
How to Get Rid of an Ice Dam
If you already have an ice dam forming, here are a few ways to safely remove it:
- Use a Roof Rake – Gently pull snow off your roof from the ground. Avoid using sharp tools that could damage your shingles.
- Create Drainage Channels – You can melt sections of the ice dam by applying calcium chloride (NOT rock salt, which can damage your roof). Fill a nylon stocking with the de-icer and lay it across the ice dam to help create drainage paths.
- Call a Professional – If ice dams are severe or water has started leaking into your home, it's best to call in a professional roofing or ice removal service.
