Ice Dam

An ice dam is a buildup of ice along the edges of a roof that can prevent melting snow and ice from draining off the roof. Ice dams are typically formed when heat from inside the building escapes through the roof, causing the snow on the roof to melt and then refreeze as it reaches the colder edges of the roof. Over time, the ice buildup can prevent water from draining off the roof, leading to water damage and other issues.

Ice dams can be a significant problem in areas with cold winter weather and heavy snowfall, and can cause a range of issues for homeowners and building owners. These issues can include water damage to ceilings and walls, damage to roofing materials, and mold and mildew growth.

Preventing ice dams requires proper insulation and ventilation of the roof and attic space, as well as regular maintenance and cleaning of the roof. This may include removing snow from the roof, installing ice and water shield under the roofing materials, and ensuring that gutters and downspouts are clear and functioning properly.

If an ice dam does form, it is important to address the issue as quickly as possible to prevent water damage and other issues. This may involve removing the ice dam with a roof rake or other tool, or using professional services to remove the ice and prevent further damage.

Overall, ice dams are a common and potentially serious problem for homeowners and building owners in cold weather climates, and should be addressed through proper insulation, ventilation, and maintenance of the roof and attic space.
