What Are Ice Dams?
Ice dams form due to the temperature difference between the top of your roof and the eaves. When you are heating your home in the winter, the excess heat escapes through the top, which causes the snow on the top of your roof to melt. When this snow melts, it rolls down the roof to the eaves and gutters. When it reaches the edges of your roof, it refreezes because the eaves of your roof aren’t being heated by your home. Eventually, this causes large patches of ice to form, clogging your gutters. Once this happens, the water that was running down your roof to begin to back-up and pool because it’s being heated enough by your home to remain liquid but not enough to evaporate, and because the ice has backed up into your gutters and up onto your roof, the water has nowhere to drain. Ice dams can cause a lot of damage to your home, from damaging your gutters, to breaking your shingles, to causing water to leak into your home. Therefore, it is important to address ice dams as soon as they form. There are a few different ways to address this issue that we’ll cover here. If you are looking to address an ice dam that’s already formed, that are a couple of relatively easy solutions. Some involve using heat and some involve cooling, but they all accomplish the goal of removing the ice dams.
If you are determined to melt the ice on your roof, you can try using heated cables along the eaves of the roof. Since the ice dams form because your eaves are cold enough for the water to refreeze, heating the eaves should fix the issue.
Another option for melting the ice is to fill old pantyhose with calcium chloride. The permeable material allows you to lay the pantyhose wherever you want along the roof and melt a channel for the water to drain.
Cooling From The Inside
Another option, rather than melting the snow, is to cool the roof. If you have an area where water is pooling and moisture is leaking in, you put a fan in your roof and point it at the problem area. The cool breeze will cause the water to freeze within minutes, and if the water is frozen it cant leak into your home.
Still Having Problems With Your Ice Dams?
If your home tends to have problems with ice dams in the winter, there are steps that can be taken to make your roof less susceptible to ice dams such as installing insulation to prevent heat from escaping through your roof and melting the snow.
