What Are Ice Dams and How Do They Affect Metal Roofs?

Ice dams can be a frustrating and expensive winter occurrence if they are not dealt with properly. They occur when the heat inside your home gets into your attic and begins to warm the roof. The warming will cause an accumulation of snow to melt, which turns into water that runs under the remaining snow buildup.

Once this water gets to the edge of the roof, it will refreeze and create a dam. When a buildup of melted snow starts to slide off the area, it can develop icicles, indicating you have a problem.

Why Are Ice Dams a Hazard?

The ice dam is considered a hazard because it can trap water that is melted on the roof. It can even accumulate and seep under the shingles, thus entering your home and creating extensive damage to your walls. This is why ice dam prevention is a priority for your home.

How Do Ice Dams Affect a Metal Roof?

The great thing about having a metal roof is that it can help prevent or reduce ice dams. A few factors can help decrease the buildup, and one is in the way of the design in a metal seam roofing. This design is vertically seamless, which means that if ice does build up on your roof there is less chance of it getting under your roofing system like with typical asphalt shingles.

In addition, the smoother surface and the way the material handles heat distribution tend to make the snow melt more quickly, which can also reduce buildups. Because of the reduced friction on the panels, the snow and water will come off of the roof faster than it does with asphalt shingles.

Other Considerations

A metal roof is a good starting place, but there are other things you can do to support the reduction of buildup:

  • Ensure there are no hot air leaks from your home into the attic.
  • Check the area for proper insulation and use weatherstripping to seal as many cracks and leaks as possible.
  • Make sure there is good ventilation in the attic and install a ridge vent as the increased surface area allows for faster release of any heat in your attic..

Some other products can be used to prevent ice dams from forming:

Heating Cables

These can be placed around the eaves of your roof and turned on if there is snow predicted, thus preventing the freezing process and stopping the dam from forming.

Snow Rake

Another option is a specialized rake that removes the snow by pushing it off the roof. This automatically eliminates the buildup and terminates the stress of getting an ice dam. Please

do not rake your metal roof as it can scratch your metal panels.
