Three Ways to Melt an Ice Dam

If an ice dam has formed on your roof, you could experience a leak or damage to the shingles. While roof heating cables will eliminate the problem for good, you should try to melt the ice dam as quickly as possible. Here are three ways you can attempt to melt an ice dam as quickly and safely as possible.

Warm Water

Warm water can be used to melt an ice dam in an emergency situation, but it can be difficult to use properly. Simply apply the warm water to the roof, starting at the area furthest away from the edge of the roof and working your way down.

Be warned, however, that a large amount of warm water may be required to do this properly. You must also watch for ice falling from the roof, which could knock you from your ladder. If at all possible, a garden hose attached to the hot water tap on your kitchen sink is the best supplier of hot water in most residences. Take your time to remove all of the ice when using this method.

Calcium Chloride

Calcium chloride will melt the ice dam, but only if it is warm enough for water to melt. However, if it is a relatively sunny day, it will definitely speed the process. Although you can sprinkle calcium chloride onto the ice dam, stuffing calcium chloride in pantyhose, to create a long tube of calcium chloride is the best.

Place the calcium chloride, once prepared, directly onto the ice dam. Use as much as needed to encourage the ice to melt. You should also monitor the area and shift the bags of calcium chloride as necessary to remove any stubborn ice.

Ice Chipping

Although this method does not melt the ice dam, it does help remove it. Use a ice pick, or small chisel, you can remove the ice from your roof. The problem with this method is that asphalt is incredibly brittle in the cold. The risk from damaging your roof is high, especially if you are inexperienced. Normally, ice chipping is used in conjunction with a heat gun to melt bits of ice that are not easy to remove.

This method works, but is often employed by professionals, not homeowners. Consider calling a professional if this is your only option. Someone you hire will have insurance if the roof is damaged- and will be able to fix any damage quickly.
