During the winter months, many homeowners in colder climates face a hidden threat to their plumbing systems: ice dams. These formations can cause significant water damage to your roof, gutters, and plumbing. If left unchecked, ice dams can lead to leaks and burst pipes, creating a costly nightmare.

At ERM Plumbing and Heating, we understand that preventing ice dams and the plumbing damage they can cause is key to keeping your home safe during winter. In this blog, we'll explain what ice dams are, how they form, and what you can do to prevent them from impacting your plumbing system.

What Are Ice Dams and How Do They Affect Your Plumbing?

Ice dams form when snow on your roof melts and the water runs down the roofline, only to refreeze at the eaves or gutter line, where temperatures are colder. This process creates a barrier of ice that traps water behind it, causing it to pool. If the water seeps under shingles, it can leak into your home, potentially damaging your plumbing, ceilings, and walls.

The real danger for your plumbing comes when the water enters the attic or walls and freezes inside pipes. The freezing water can cause the pipes to expand and burst, leading to flooding and water damage.

How Can I Prevent Ice Dams from Forming?

Preventing ice dams requires a proactive approach. Here are a few things you can do to protect your plumbing system:

1. Ensure Proper Insulation in Your Attic: Make sure your attic is well-insulated. This helps to maintain a consistent temperature in your attic, preventing heat from escaping and melting snow on your roof. Proper insulation keeps the roof cold, minimizing the likelihood of snowmelt that leads to ice dams.
2. Ventilate the Attic: Ensure your attic is well-ventilated. Proper ventilation helps regulate temperature, preventing warm air from accumulating and causing the snow to melt. Ventilation allows cold air to circulate, keeping the roof cold enough to prevent ice buildup.
3. Install a Heated Gutter System: A heated gutter system can be a game-changer in preventing ice dams. These systems use heat cables to melt ice and snow in the gutters, allowing water to flow freely without causing ice buildup.
4. Clear Gutters Regularly: Clogged gutters are more likely to create ice dams. Make sure to clear your gutters of leaves, debris, and ice before winter. This ensures water can flow freely through your gutters, preventing the formation of dams.

What Should I Do If I Already Have an Ice Dam?

If you suspect that an ice dam has already formed on your roof, it's crucial to act quickly to prevent damage. Here are steps to take:

1. Carefully Remove Snow from the Roof: Using a roof rake, carefully remove any accumulated snow from the roof. Start at the edge and work your way up, but be cautious not to damage the shingles or cause harm to yourself.
2. Use Ice Dam Removal Products: There are specific products available that can help break up the ice dam. These often contain calcium chloride, which can be safely used to melt the ice. Avoid using salt, as it can damage your roof and gutters.
3. Call a Professional: If the ice dam is large or you’re unable to safely remove it, call a roofing or plumbing professional. They have the right tools and experience to remove ice dams without damaging your home or plumbing system.
