What To Do If Your Downspouts Freeze!

Prevent Your Downspouts from Freezing

Of course, if you can prevent a frozen downspout, that is the best course of action. There are a few ways to shrink the chances that your downspouts will freeze: one is to wrap them with heat tape, especially at the elbows of your pipes where there can be stagnant water. You can also run a heat cable inside of your downspout to prevent water from freezing in that way. Heat cables can also be run along your roof to prevent ice dams from making their way down your downspout.

Safely Clear Ice from your Frozen Downspout

So, your downspout is already frozen. There are a handful of ways to safely clear the ice but do not try using brute force, like hitting your downspout with a baseball bat, to attempt to break up the ice inside. This almost always does more harm than good. To safely clear the ice, check to see if there is a lot of snow around the bottom of your downspout. Sometimes the pipe itself isn’t frozen, the water just can’t escape through the bottom. If you have a lot of snow, just clear it with a shovel. If that doesn’t help and it’s safe to get on a ladder, try pouring warm water down the spout, and that will clear minor ice buildup or break up any blockages. A safer option is to use hot water on the outside of your downspout, either by pouring or spraying with a hose connected to a hot tap. If your pipe is still frozen, you can use a hair dryer to heat up the outside of your downspout. Start near a blockage if you can locate one, or start near the bottom of the downspout and work upward. Never direct heat directly into the downspout opening, as this can pose an electrocution hazard if the blockage breaks up and water comes rushing out.
