What to Know About Frozen Downspouts


As winter draws near, it’s important to take steps to prepare your home for the colder weather. One of the things you should do is check your downspouts to make sure they are free of ice and snow. If they are frozen, they can cause water damage to your home. Here’s what you need to know about frozen downspouts and how to prevent them from happening.

What is a downspout and what does it do?

A downspout is a pipe that carries rainwater from the gutters on your roof to the ground. It helps prevent water damage to your home by directing water away from the foundation of your home.

If you live in an area that gets a lot of snow, you may have noticed that your downspouts can become frozen. This can cause problems because the water can’t flow properly and may back up into your gutters or even into your home.

Why do downspouts freeze?

Downspouts typically freeze when water seeps into the spout and then freezes. This can happen when there is snow or ice on the ground that melts and runs down the spout, or when rainwater leaks into the spout. Once the water freezes, it can block the flow of water down the spout, causing an ice dam to form.

Why are frozen downspouts bad?

Frozen downspouts are bad because they prevent water from draining properly, which can lead to water damage and flooding. Additionally, compact snow and ice can build up and cause the downspout to collapse, damaging your roof. This is why it is important to clear your downspouts of any ice or snow whenever possible.

How do you prevent downspouts from freezing?

There are a few things you can do to prevent your downspouts from freezing:

  • Install gutter guards or covers to keep leaves and debris out of your gutters. This will reduce the amount of water that can seep into your gutters and freeze. You can also look into a downspout ice guard. A downspout ice guard is a device that is placed over the top of a downspout to prevent ice from forming. It typically has a heating element that melts any snow or ice that comes into contact with it. To install a downspout ice guard, simply place it over the top of the downspout and secure it in place. Most models come with easy-to-follow instructions.
  • Repair any leaks in your gutters or downspouts. This will help to prevent water from seeping in and freezing.
  • Clear your gutters and downspouts of any leaves, debris, or snow. This will help to ensure that water can flow freely and will not have a chance to freeze.
  • Insulate your gutters and downspouts. This will help to keep them warm so that water is less likely to freeze.
  • Apply heat tape or cables to your gutters and downspouts. This will help to prevent ice from forming.

How do you thaw a frozen downspout?

If your downspout is already frozen, there are a few things you can do to thaw it out:

  • Apply heat to the downspout. You can use a hairdryer, heat gun, or even a blow torch. Just be careful not to overheat the downspout and damage it.
  • Use hot water. Pour some hot water over the downspout and wait for it to melt the ice.
  • Use salt. Sprinkle salt on the ice and wait for it to melt. You may need to reapply several times.
  • Use an ice pick or chisel. Chip away at the ice until you clear a path for the water to flow. Be careful not to damage the downspout.

Should I take downspouts off in the winter?

You should leave downspouts in place during the winter as they help to prevent water damage. However, you should regularly clear them of any ice or snow to ensure that they are working properly.
