An ice dam on your roof poses a serious threat to your home. These ridges of ice block water from getting to your gutter system. As a consequence, water can pool up and begin to seep underneath your shingles. The result will be water leaks inside your home and serious damage. It also increases the weight on your roof, which can cause structural damage. Fortunately, it's not too difficult to eliminate ice dams using a device known as a snow melt sock. Your snow melt sock can be either homemade or a commercial one. The following will show you how to use this device to clear an ice dam off your roof.
What You Will Need
Ice Melt Sock or Sleeve
Potassium Chloride or Magnesium Acetate (a Noncorrosive Ice Melt)
Plastic Zip Ties or a Length of Wire
Step 1. Fill up your snow melt sock with either potassium chloride or magnesium acetate. Both of these are a noncorrosive ice melt, which is what you want on your roof. Do not use magnesium chloride or rock salt, since these are corrosive compounds.
Step 2. Now close up the snow melt sock so that the icemelt you are using can't pour out. While some commercial ice socks have hook and loop fasteners, for a homemade version, you can use plastic zip ties or wire that you tighten on with a pair of pliers.
Step 3. Tie one end of a rope to the snow melt sock. Make sure you're tying onto the end that is tied up or closed by the hook and loop fastener. The rope that you're using should be much longer than the distance you need to actually get to the ice dam on the roof. For a one-story house, your rope should be about 15 feet long.
Step 4. Position yourself on the side of your house that has the ice dam. Put one foot on the other end of the rope and toss the snow belt sock up onto your roof. Try to overshoot the ice dam so that you can slowly pull the snow melt sock back down over the spot where you want it. Make sure it is lying directly on the ice dam.
Step 5. Keep the sock there until it has melted through the ridge of ice, creating a channel that the water can flow through. Then use the rope to pull the snow melt sock back down.
