What Are Ice Dams?

Ice dams are a build up of ice on sloped roofs. They occur when snow that’s under a snowpack melts and then refreezes – usually caused by warm attic air. This creates a layer of ice that can wreak havoc on the roof and chimney system.

Why Ice Dams are Dangerous

Damage to Your Chimney

There are multiple reasons why ice dams are dangerous for your home. First, they can cause damage to your chimney. If your chimney is on the ridge of your home, it will most likely be safe from ice dams. Chimneys that are located on other parts of a roof can actually cause ice dams to form, however.  Be on the lookout for ice dams if your chimney is located on one of the corners of your roof or on a sloped section of your roof.  Ice dams can also damage the masonry or flashing of your chimney, causing it to pull away and crack.

Damage to Your Roof and Gutters

In addition to damaging your chimney, ice dams can cause roofing and gutter issues. They often cause roof flashing to bend, which can allow water to penetrate your attic. Ice dams can also warp  your gutters as the ice expands and contracts. Sometimes gutters even fall off of homes because of this!

What to Do if You Have Ice Dams

Ice Dam Prevention

There are some steps that you can take to avoid ice dams. First you can have a chimney professional check the flashing that is around your chimney. If there are cracks in your chimney flashing, it can separate from your chimney structure and allow water to enter your home.

We also recommend adding more insulation to your attic floor to keep warm air inside of your home and out of your attic, which should be the same temperature as outside.

During a chimney inspection, we can assess the state of your chimney’s masonry, flashing, and more to assess if it has been damaged by ice dams or if it is vulnerable to being damaged by ice dams or winter weather in the future.
