With winter right around the corner, many homeowners will be dealing with bothersome ice dams on their roofs very soon. These ridges of ice accumulate at the edge of the roof and are associated with a wide range of issues. While a roofing contractor can help you deal with problems caused by snow and ice, the following information can help avoid issues in the first place. 

What Causes Ice Dams to Form?

Temperature differentials on the surface of the roof are key to forming ice dams. If the upper portions are above freezing temperatures, snow will melt and run down the roof as expected. However, when the lower parts of the roof are below freezing, it forms into ice, blocking melted snow from leaving via your gutter system and keeping it trapped on the roof. 

How Can They Damage the Roof?

When water is trapped on the roof regularly, materials will wear down at a much faster rate. This can increase your risk of roof leaks, which can cause water to intrude into your home. Along with damage to furniture and fixtures, roof leaks can also contribute to mold growth, greatly degrading indoor air quality.

Accumulating ice on your roof can also cause damage to the gutter system if it becomes too heavy and causes the fasteners to loosen. When the water can’t exit via the gutter system, it will back up and seep under the flashing.

How Can Ice Dams Be Prevented?

Fluctuating temperatures on the roof can often be remedied by boosting insulation in your attic, which helps the space retain a uniform temperature throughout the season. You can also shore up gaps between the lower floors of your home and the attic, as this will prevent hot air from rising into the space. 

After a storm, you can use a snow rake to remove the material before it melts onto your roof. Before the winter weather kicks in, having ventilation around the eaves and ridge will keep the attic air dry and less prone to moisture.
