Can Ice Dams Cause Roof Damage?
Winter can be harsh on your roof. Frigid temperatures, high winds, heavy snow, and ice can all put a beating on your roof. One of the most common winter factors that can affect your home is roof ice dams. You may be wondering what are roof ice dams and can they cause damage? If so, how can you prevent them from forming?
Ice dams are thick ridges of solid ice that form along the edge of a roofline. Ice dams form when heavy snow on the roof begins to melt during the day, flows down to the eaves, and then refreezes overnight. Heat from within the home rises and warms the roof decking and shingles, melting the snow and causing it to flow down, where it meets the edge not warmed by the attic. Once it hits the cold edge, it refreezes, creating a rim or block of ice.
This pattern repeats and the rim grows, forming an ice dam. New snow melt is then trapped by the dam. The dam subsequently forces this trapped water back up under the shingles, where it can lead to roof rot and cause your roof to leak, causing exterior and interior damage to your home. Water can drip down through insulation and walls, peeling paint, damaging drywall, and create a mold and mildew problem. Additionally, the heavy weight of the ice can tear down gutters and cause soffit damage.
How To Prevent Roof Ice Dams
There are a few steps you can take to help prevent roof ice dams from forming and potentially damaging your roof, including:
Keep Your Gutters Clear of Debris
Clear all leaves, sticks, and other debris from your gutters and downspouts. Keeping your gutters clear will help water from the melting ice flow through your gutters and through your downspouts.
Rake Snowfall Off of Your Roof
Snow rakes are aluminum poles with telescoping handles so you can reach your roof from the ground. Using a lightweight roof rake, clear your roof of snow before it has an opportunity to melt in order to lessen the chance of ice buildup.
Add Attic Insulation
The warm air rising from within the house and the cold air outside cause the thaw/freeze cycle that forms ice dams. Ensuring that your attic is properly insulated to help prevent heat loss can reduce the potential of roof ice dams forming.
Ventilate Your Attic
A well-ventilated attic will keep cool air circulating instead of heat building up in your attic and warming your roof. You can install exhaust vents on top of your roof and attic vents along the eaves to help redirect airflow. Proper attic ventilation is key in helping prevent roof ice dams.
