🍂🍁🍃Gutter cleaning season is upon us. Always make sure to clean your gutters spring and fall and avoid the protection systems that are often advertised.
Gutter guards and gutter protection systems are designed to keep debris out of gutters, but they can inadvertently contribute to the formation of ice dams during winter months. Here’s how this happens:
Mechanisms Contributing to Ice Dams
1. Restricted Water Flow:
• Gutter guards can sometimes become clogged with smaller debris, such as pine needles or granules from shingles. When this occurs, the flow of water through the gutters is restricted, preventing proper drainage.
• If water cannot flow freely through the gutters, it may back up and freeze in the colder parts of the gutter system.
2. Heat Retention:
• Some gutter protection systems are designed with materials that can hold heat. This can cause melting snow on the roof to flow into the gutters. If the gutters are blocked or poorly designed, this water can freeze, contributing to ice dam formation.
• Additionally, if the heat from the home (from the attic or living spaces) escapes through the roof, it can cause the snow to melt unevenly, leading to more water flowing towards the gutters where it may freeze.
3. Improper Installation:
• If the gutter guards are not installed properly, they can create areas where water can pool instead of draining effectively. This pooling can freeze and form ice dams.
• Gaps or misalignments in the installation can also allow cold air to enter and contribute to freezing temperatures in the gutter system.
4. Snow Accumulation:
• Heavy snowfall can exacerbate the problem. If the gutters are covered by snow and then ice, the weight can cause further blockage, creating a dam effect at the edge of the roof.
• When the snow on the roof melts but cannot drain due to the blocked gutters, it will refreeze at the edges of the roof, forming ice dams.
Key Takeaways
• Clogging: Gutter guards can become clogged, restricting water flow.
• Heat Retention: Some systems may retain heat, contributing to melting and freezing.
• Installation Issues: Improper installation can lead to pooling and blockage.
• Snow Accumulation: Heavy snow that melts but cannot drain will refreeze and create ice dams
