Brutal winter weather can cause significant damage to your roof. Ice dams are just one potential concern for homeowners, as they will result in the need for roof repair or even replacement when damage is severe. The following information explains how ice dams form, why they’re an issue, and how you can prevent them.

How Do Ice Dams Form?

Because heat rises, the top of your roof is often warmer than the edges, which are also known as eaves. As a result, snow and ice that has accumulated at the top will melt and refreeze on the cooler eaves, forming an ice dam. If you see icicles hanging off the edges of your roof, you likely have an ice dam.

Why Are Ice Dams Harmful?

Roofs are designed for water to flow down the shingles, through the gutters, and to the ground. Ice dams prevent this from happening, which means water can back up onto the roof. As it builds up, water can leak through the roof and soak the insulation, decreasing its effectiveness. Additionally, the water can damage the structure of the roof and anything in your attic.  Without proper roof repair, leaking water can damage interior fixtures, contribute to mold growth, and impact your ability to keep your home warm during the winter.

How Can I Prevent Ice Dams?

The best way to prevent ice dams is to ensure your roof is properly ventilated. This requires the assistance of a roofing contractor, who can install a soffit and ridge vent system to facilitate proper airflow through your roof, which helps it maintain a consistent temperature. Also, make sure your attic is insulated well and the gutters are clear before winter hits. It’s also a good idea to clear snow from your roof after a winter storm.
