BLOG How to Safely Remove Ice Dams from Your Roof During Winter Jun 04, 2025

Winter is a magical time, but it can also bring some unwelcome challenges, especially for homeowners. One such challenge is the formation of ice dams on roofs. Ice dams occur when snow on your roof melts, runs down and refreezes near the edges, causing problematic blockages. These can lead to leaks, damaged gutters, and can compromise the structural integrity of your roof. At BlueJay's Roofing & Roof Repair, we understand the importance of keeping your roof in top condition. In this article, we’ll provide practical advice on how to safely remove ice dams from your roof and protect your home during winter.

Before diving into removal methods, it's essential to note why ice dams form. They typically occur when heat from the attic warms the roof, melting the snow. As the melted snow reaches the colder eaves, it refreezes. This process repeats, resulting in a thick ice dam that traps additional water, leading to potential leaks.

The most critical step in removing ice dams is ensuring your safety. Climbing onto a roof in icy conditions can be dangerous. It's recommended to use a roof rake from the ground to safely remove the snow near the roof’s edge. These rakes are specifically designed for snow removal and have long handles that allow you to stand on solid ground. Avoid using ladders because they can slip on an icy surface, posing a significant risk.

Another effective method is to use calcium chloride ice melt. Contrary to common salts, calcium chloride is less corrosive and works effectively in low temperatures. Fill a nylon stocking with calcium chloride and place it directly on the ice dam, perpendicular to the roof's edge. This will help to melt through the dam, creating a channel for water to flow off the roof. Make sure to use calcium chloride rather than rock salt, as rock salt can damage your roof and landscape.

It's crucial to avoid using sharp tools like axes or ice picks to chisel away at ice dams. Not only is this risky for your safety, but it can also damage your shingles and the structural components of your roof. An alternative to consider, though potentially more costly, is hiring professionals like BlueJay's Roofing & Roof Repair to safely handle the situation. Professionals are trained to use specialized equipment to effectively deal with ice dams without causing harm to your roof.

Aside from immediate removal, preventing future ice dams is key. Ensure your attic is properly insulated and ventilated to keep the roof cold. This can prevent the snow from melting in the first place. Regularly cleaning gutters during the fall also helps, as clear gutters allow melting snow to drain properly, avoiding any refreezing issues.

In conclusion, while ice dams are a common winter issue, they don't have to be a daunting challenge. By taking the necessary precautions and implementing the right techniques, homeowners can safely manage and prevent ice dams. If you feel unsure or unsafe dealing with ice dams on your own, remember that professional help is always a phone call away.
