How Much Snow Does it Take to Make an Ice Dam

Ice dams are ridges of ice that form at the edge of a roof, preventing melting snow from draining properly. Ice dams can cause multiple roof ice problems, and ultimately can lead to permanent structural damage that can cost thousands of dollars to repair properly.

Since ice dams prevent the proper flow of melting snow, you may be asking yourself the question: How much snow does it take to make an ice dam in the first place?

It is a common rule of thumb to be cautious of any snowfall that accumulates on your roof in the amount of six inches or more. Once snow reaches this level, the chances of an ice dam forming and causing severe roof problems grows exponentially.

However, ice dams have been known to occur underneath even the lightest dustings of snow. That is why you have to be vigilant and look for the signs of ice dams and roof ice problems as the first snowflakes start to fall.

If you see icicles forming under the eaves of your home, it is possible that an ice dam and all the roof ice problems it brings along with it is not far behind. Make sure to take photos on your smartphone or other device of icicles as soon as you seem them forming. This photographic evidence may help you target the source of leaks inside your home.

Long story short: regardless of the amount of snow, it is within its power to create an ice dam on your roof. Of course, snow that is heavy and falls in large amounts has a greater chance of building an ice dam that will later melt and flow under your shingles and into your house. Ice dams have the potential of causing severe damage to the roof, walls and overall structure of your home.
