What Causes Roof Ice Dams and How To Prevent Them

Once you have a roof ice dam, runoff from melted snow can’t reach your gutter system. Instead, this water can back up under roof shingles and get into your attic. These roof leaks can cause several problems for your home. You can end up with damaged roofing shingles that need to be replaced. Shingle damage or loosened shingles that come off can allow even more water into your attic, especially when you still have an ice dam. As water leaks into your roof and attic, the risk of a mold problem increases.

Clean Your Gutters

Keeping your gutters clean helps ensure that melted snow has a path to the downspouts. This helps keep water from building up in your gutters and freezing. Clear out any branches and other debris that are in your gutters.

Check Your Gutters and Downspouts

Make sure your gutter system doesn’t have any ice buildup. Check it regularly throughout winter. Keeping the gutters and downspouts clear of ice allows melted snow to flow off your roof.

Clear Off Snow

Having snow pile up on your roof can raise the risk of ice dams and structural problems if it weighs too much. Don’t go up on your roof to shovel snow, though, since this is dangerous. You can use a long-handled roof rake to push snow off your roof while you stand on the ground.

Check Your Attic Insulation

Having enough insulation in your attic means heat can’t escape through your roof. When heat from the inside goes through your roof, it can cause snow to melt unevenly. Snow can melt quickly in some areas and more slowly in others. This increases the risk of having ice dams.

Check Attic Ventilation

Adequate ventilation helps keep the air in your attic colder. This helps reduce the risk of thawing and freezing cycles, leading to ice dam formation. Professional roofers can improve your attic ventilation as needed.

Install an Ice Dam Shield

Having shields installed along the eaves of your roof can help stop ice dams from developing. These shields help ensure that melted snow can flow from your roof instead of backing up under the shingles.
