If you have a home that gets winter weather, ice on your roof can be very damaging. The melting snow can cause ice dams as the snowfall melts and re-freezes. This frozen water can then wear on your roof and cause leaks at eaves and anywhere ice dams have formed. There are some things that you can do to prevent ice damage, such as install a membrane or heated cables. Here are some of the things that you may want to consider doing to prevent damage to your roof:

1. Using A Rubber Membrane At The Eaves Of Your Roof

The eaves of your roof are one of the most likely places that you are going to have problems. One way for you to protect your roof is to install a rubber membrane. These can be self-adhesive strips that are installed beneath the shingles at the edges of your roof. The membrane will protect this area of your roof from condensation and leaks, but will not protect shingles from wear that ice dams can cause. This can be good for mild climates with limited risk of ice dams.

2. Keeping Your Roof Clear Of Melting Snowfall

Keeping roofs clear of snow can also help to protect your home from ice dams. Snowfall and the melting is what cause the ice dams. This is caused by the snow melting in the sunlight during the day and then refreezing at night. If you have any significant amount of snow, use a shovel to remove it from your roof to prevent it from refreezing and causing damage to your home.

3. Insulating Attic Space To Prevent Snowmelt

Another cause of melting and ice dams is the heating in your home. If you have poor attic insulation, the rising heat can melt snow and cause ice dams. To prevent this, you can improve attic insulation. Another improvement that can be done is to insulate rafters in the attic, which will prevent rising heat from melting the snow on your roof.

4. Installing Heated Cables In Extreme Cases

In some areas, high snowfall and ice storms can make preventing ice dams challenging. For these situations, using a defrost cable system may be the best solution. This is a system of heated cables that will melt snow and ice to prevent the ice dams from ever forming. The defrost cables can be installed in areas where ice dams are likely to form and melt the ice when it forms in these areas.

These are some of the things that can be done to prevent damage to your roof due to ice dams. If you need help with some of the repairs and improvements, contact a roofer and ask about the best ice dam prevention strategies for your home.
