SnowIce Risk Mitigation Email - 600x400px (1)](https://blog.caaniagara.ca/hs-fs/hubfs/H%26A%20-%20SnowIce%20Risk%20Mitigation%20Email%20-%20600x400px%20(1).png?width=600&height=400&name=H%26A%20-%20SnowIce%20Risk%20Mitigation%20Email%20-%20600x400px%20(1).png) ## Don’t let hidden ice damage your home this winter Ice dams are one of the most common winter issues faced by homeowners in Niagara — and one of the most costly if left unchecked. Understanding how they form and what you can do about them is the first step to protecting your home. ### What is an Ice Dam? An ice dam occurs when warm air from inside your home causes snow on the roof to melt. As the water runs down and reaches the colder edge of your roof, it refreezes into a ridge of ice. Over time, this ridge traps additional meltwater, which can seep under shingles and leak into your home. ### Warning Signs - Icicles forming along your roofline. - Water stains on ceilings or in the attic. - Uneven snow melt — some roof sections are bare while others are snow-covered. - Gutters blocked with ice and debris. ### How to Prevent Ice Dams - **Improve attic insulation** – Keep warm air from escaping into the roof space. - **Seal gaps and leaks** – Pay special attention to areas around vents, chimneys, and attic hatches. - **Ensure proper ventilation** – Good airflow helps keep your roof at an even temperature. - **Keep gutters clear** – Clean out leaves and debris before winter arrives. - **Remove roof snow safely** – Use a roof rake or hire professionals after major storms to reduce buildup. ### Safe Removal Options If an ice dam has already formed, avoid trying to chip away at it — this can damage your shingles. Instead, consider: - De-icing cables to keep a clear drainage path. - Chemical de-icers designed for roofs and gutters. - Professional removal services for large or stubborn ice dams. ### Protecting Your Home Further Even with all precautions, extreme weather or old building materials can allow damage. It’s wise to pair preventive efforts with insurance coverage to safeguard against unexpected harm.
