Roofing companies will attest that ice dams are a common problem for many homeowners, and failing to prevent their formation often leads to costly repairs or replacements. In this blog post, we will discuss what ice dams are and why they form so that you can avoid having to deal with them.
What Is an Ice Dam?
An ice dam is a ridge of ice that forms at the edge of your roof into an impenetrable barrier. As temperatures rise and fall, causing snow to melt on the warmer upper part of your roof and refreeze along the colder edges, water is trapped beneath the dam, where it can eventually seep into your home’s interior walls and ceilings. As more water accumulates behind this wall, it can cause serious damage by infiltrating small cracks or openings, eventually requiring you to get a roof replacement.
What Causes Ice Dams to Form?
- Heat Loss: When warm air escapes through the attic and rises to the roof, it melts snow and ice on your roof’s surface. This water then refreezes along the edges of your roof, creating a solid barrier. To prevent this, ensure all gaps or openings in walls or ceilings are sealed properly to avoid unnecessary heat loss.
- Poor Attic Ventilation: When the temperature in your attic is significantly higher than the outside air, it can cause snow and ice to melt more quickly on your roof’s surface. Ensure all vents are properly sealed and insulated.
- Inadequate Roof Insulation: When your roof doesn’t have enough insulation, it can cause large temperature fluctuations on the surface of your roof, leading to melting and refreezing. To avoid the need for a roof repair ensure all attic areas are properly insulated and sealed off from outside air.
- Clogged Gutters: Finally, ice dams can form due to clogged gutters. When snow and ice accumulate in your gutters, it prevents water from draining properly. This causes a buildup of water on the surface of your roof, which can then freeze along the edges. Regularly clean and maintain your gutters throughout the winter season to stop ice buildup from occurring.
