Denver Roofer Explains How to Prevent Ice Dams


November 15, 2017

Ice dams are one of the most common—and damaging—roofing problems that can arise during the winter. According to an experienced Denver roofer, an ice dam forms when snow falls onto a roof and begins to melt due to the heat coming from inside the home. The water then flows to the edge of the roof, which is much colder than other areas of the roof. As a result, the water refreezes and forms an ice dam that can block water from flowing off of the roof, eventually leading to shingle damage and leaks.

Fortunately, there are a few ways to prevent ice dams from forming so you can avoid having to pay for costly roof repairs in the middle of winter. Here are tips to prevent the formation of ice dams on your roof:

Clean the Gutters

Ice dams can form when melted water is unable to drain off of the roof because the gutters are clogged. When this happens, the water is forced to remain on the roof, where it will refreeze over time and form an ice dam. To prevent this problem, it’s recommended that you schedule an appointment with a local roofer so he can clean your gutters before winter arrives.

Prevent Heat Loss

The best way to prevent ice dams from forming is to reduce the amount of heat that is lost through your roof. This ensures that the roof never gets warm enough to melt the snow, which means ice dams will never form.

How can you prevent heat loss? By ensuring that your attic is properly insulated and ventilated. Start off by adding insulation to the attic floor, recessed lighting, and attic stairway. As the heat rises through your home, this insulation will prevent it from going into the attic and raising the temperature of the roof. Learn how to prevent ice dams.

Next, tackle the attic’s ventilation. A ventilation system will draw in cold air from outside of the home and let warm air from inside escape to maintain a cool temperature inside the attic. If your attic is not properly ventilated, get in touch with a professional to discuss adding soffit, gable, or ridge vents. The size of the openings that you will need on your ventilation system will depend on the size of your attic. It’s advised that homeowners have at least one square foot of openings in the ventilation system for every 300 square feet of space in the attic. This should be enough to ensure that your attic is properly ventilated so you don’t have to worry about the formation of ice dams.
