Snow and Your Roof

With winter right around the corner, so to speak, you need to know about snow and your roof. Snow can affect your roof in several ways.


Even though it is winter, snow on your roof can melt and refreeze. This is one of those aspects of snow and your roof that most people don’t think about.

The runoff of this snowmelt goes into your gutters. If your gutters are clear, there’s usually no problem. But what if they’re not clear?

If your gutters are not clear, this water from melting snow can overflow and freeze as icicles. While icicles are pretty at times and can even add a festive atmosphere to your home, they also are dangerous. They can break and fall onto people or onto parts of your home.

Another part of this aspect of snow and your roof is that ice dams can form. If this happens, the water from melting snow can back up and seep under the shingles on your roof. When this happens, the water can either seep into your home causing damage or it can refreeze under your shingles, loosening or warping them.

Stress On Your Roof

Snow and your roof becomes problematic when the snow builds up. This added weight on your roof can lead to too much stress and then damage. This is especially a problem if the snow is a wet snow. One difficult issue when faced with built-up snow and your roof is that you won’t always be able to tell your roof is stressed.

A good rule of thumb is when the snow on your roof reaches a depth of 8 inches, you should consider having someone remove it. Taking a walk-through of your house can help you see the effect of snow on your roof. If doors in the upper levels of your house are sticking, that is a pretty good indication that there is too much snow on your roof.
