Ice damming occurs when heat escapes from your attic or top floor, melting the snow on your roof and causing water to flow down to the gutters. As the water reaches the gutters, it freezes, forming a ridge of ice that prevents further water flow.
Causes Ice Damming
This can lead to water pooling and refreezing, causing damage to your roof, walls, and ceilings.
Factors To Look Out For
- Poor Attic Insulation: When heat escapes from your attic, it melts the snow on your roof, causing water to flow down to the gutters.
- Clogged Gutters: Leaves, sticks, debris, or ice buildup can clog gutters, preventing water from flowing freely.
- Lack of Snow Removal: Snow buildup can cause both ice dam leaks and gutter issues.
- Nonuniform Roof Surface Temperatures: Heat loss from your house, snow cover, and outside temperatures interact to form ice dams.
How to Prevent Causes Ice Damming
- Ensure proper attic insulation
- Clean gutters regularly
- Rake the snow off your roof
- Install snow guards to stop snow from sliding off your roof
- Use weatherproofing techniques to keep your gutters clean
- Seal air leaks in your home to prevent heat loss
- Regularly maintain your heat tape
Frequently Asked Questions
How do I install heat tape on gutters?
Installation involves attaching the heat tape along the edge of the roof and inside the gutters and downspouts. It’s important to follow the manufacturer’s instructions carefully as some installations may need professional assistance.
What is the difference between heat tape and heat cable?
Heat tape and heat cable are both used for heating purposes, but they differ in design, power density, and installation. Heat tape is a flat, flexible product designed for high-power applications, while heat cable is a more robust and flexible product suitable for lower-power applications.
Can I leave heat tape on year-round?
While heat tape can often be left installed year-round, it should only be powered during the winter months. Disconnect it during warmer seasons to prolong its lifespan and save on energy costs.
