Ice Dams

If you live in the Twin Cities area , you’ve probably heard of ice dams. But how do they form, and how can you protect your roof from them? In this post, we’ll answer these questions and more.

All About Ice Dams

Ice dams are ridges of ice that form at the edge of a roof when water from melting snow refreezes. They’re a common problem in cold-weather climates.

How Ice Dams Form

Ice dams form when the heat from the sun or from your home melts the snow on your roof. The water then runs down to the colder edge of your roof and freezes again. This creates a dam that prevents melted snow and water from draining off your roof. As more snow melts and more water runs down, the ice dam grows larger. 

Causes of Ice Dams

There are a few things that can cause ice dams to form on your roof. One is insufficient insulation in your attic. If the heat from your home is able to escape into your attic, it will melt the snow on your roof, which can then lead to an ice dam forming. Another cause is an improperly ventilated attic. If warm air is able to escape through vents in your attic, it will also melt the snow on your roof and lead to an ice dam forming.

Dangers of Ice Dams

Ice dams can cause serious damage to your roof. The weight of the ice can damage your shingles, gutters and vinyl siding. The water that is trapped behind the dam can leak into your home and cause water damage to your ceilings, walls and floors. Ice dams can also cause your roof to collapse.

Tips for Protecting Your Roof

There are several things you can do to protect your shingles against ice dams and avoid an early roof replacement.​

Proper Attic Ventilation

One of the best ways to prevent ice dams is to make sure your attic is properly ventilated. This will help to keep the temperature in the attic consistent, which will prevent snow from melting and then refreezing at the edge of the roof.

Using a Roof Rake to Remove Snow

If you already have an ice dam, one way to remove it is with a roof rake. A roof rake is a tool that helps you remove snow from your roof without causing leaks or damaging your asphalt shingle or metal roofing.​

Applying a Roof Coating

Another solution for preventing damage from ice dams is to apply a special coating to your roof. This coating helps to reflect heat, which prevents snow from melting in the first place.
