Ice Dam on residential roof

What is an ice dam? An ice dam is an ice build-up on the eaves of sloped roofs of heated buildings that results from melting snow under a snow pack reaching the eave and freezing there.

When winter weather hits, you must take additional steps to keep your home in good shape. If an ice dam forms, your roof could leak. Here are a few things you need to know about ice dams.

When temperatures are low, these dams don’t cause much trouble. When roof temperatures rise, however, melted water pools behind the dam. As you may suspect, this water can seep under your shingles and into your home. If you have a problem with ice dams, your home could sustain significant water damage to the following building materials:

• Shingles
• Rafters
• Decking
• Insulation
• Drywall
• Ceilings

As you can imagine, the longer this goes unnoticed, the more damage it will cause. So what can you do about it?

If you have an attic, seal it off so heat cannot get in. If the roof can stay cold, then the ice will stay frozen. Check your insulation to see if it is doing it's job, if it isn't, it may be time to get new insulation. Also make sure the space is well ventilated by adding vents.

If you do notice damage in your home caused by ice dams, act quickly and get it cleaned up by a SERVPRO restoration professional. Mold can begin to grow in as little as 24 hours, so timely response is crucial to ensure safe living.

By understanding what ice dams are, you are already on your way to being more prepared should a situation occur.
