The Ultimate Guide To Ice Dams

Ice dams can be problematic for your home, and if you don’t fix them quickly, they can lead to costly repairs. Knowing why ice dams form on your home and what you can do to stop them can be helpful, however, and it can save you a great deal of time and money. Attic insulation can help prevent ice dams and protect your roof and household from serious damage. Keep reading for a look at the ultimate guide to ice dams.

Why Ice Dams Occur

When a rainstorm rolls through town, the shape of your roof becomes more important than ever. The pools of water that the storm leaves sitting on your roof may freeze over time, which can cause problems for your household. You should be particularly aware of this problem if you live in a colder climate with consistent precipitation, as these conditions can contribute to ice dams. Fortunately, there are ways you can avoid dealing with ice dams and enjoy a comfortable and efficient house.

How You Can Prevent Them

Ice dams can cause moisture to seep into your home, and this type of leak can lead to problems like water damage and mold growth. If you would like to prepare in advance and avoid these problems, consider looking into attic insulation. Insulating your attic helps to separate the exterior elements from the environment inside your home. Whether or not you decide to install attic insulation, you should check out your roof every once in a while to make sure it has not become home to ice dams.

Benefits of Insulation

Attic insulation can keep ice dams from affecting your home by preventing the moisture from reaching the inside. In doing so, attic insulation can also save you money on your energy bills and keep your home more comfortable. An attic insulation professional can help you avoid ice dams and make the most of your home.

Spotlight On Ice Damming

Icicles hanging down off your roof might look pretty in the wintertime, but they can also spell serious trouble for your roofing, gutters, and more. In order to eliminate them, you need to make sure you have enough attic insulation installed and add the proper attic vents to your home. Simply adding attic vents and keeping the air in your attic circulating at all times can prevent ice dams from forming in the first place.

Ice dams are created when pockets of cold air get trapped inside of the eaves in your attic. This cold air allows snow and water to freeze on your roof and in your gutters. By adding new attic insulation to your home and putting it an attic vent in the proper place, you can stop cold air from congregating in your attic’s eaves and eliminate ice damming from taking place.

Understanding Why Ice Dams Are Dangerous To Your Home

If you have ever experienced an ice dam on your roof, you may know how hazardous a dam can be to your attic insulation and the rest of your house. When an ice dam causes leakage, you could be looking at moldy or destroyed attic insulation in no time.

Ice dams are a solid piece of ice that collects on a roof’s edge. They block melting snow from draining off the roof, and, eventually, that water will leak through the roof and into the attic. As the water collects, it may attract mold and mildew to your attic insulation.

How Air Sealing Can Prevent Ice Dam Formation


Drafty rooms, high energy bills, fluctuating temperatures, and most of all, ice dams can make your home a good candidate for air sealing. But what is air sealing, and how does it prevent hazardous ice dam formation? Keep reading to find out.

What Is Air Sealing?

Designed to block warm air from escaping into the attic, air sealing is a cost-effective way to reduce heating and cooling costs, increase interior comfort and prevent the formation of ice dams on your roof. When combined with proper insulation, air-sealing techniques, like weatherstripping and caulking, will help keep your attic’s temperature cooler, causing less heat to leak through your roof.


How Can Air Sealing Prevent Ice Dams?

Ice dams are ridges of ice that can form along the eaves of your roof during the winter months. After a snowfall, the heat escaping from your roof can cause the snow to melt. As the water attempts to drain, it will refreeze along your roof’s edge where the temperature is suitable for ice formation. Once the ice dam has taken shape, snow melt will back up behind the ridge and can leak into your home, causing damage to walls, ceilings, insulation and other areas.

By air sealing your attic, your roof will maintain an even, cool temperature, helping prevent snow melt during days and nights where the outside temperature is below freezing. As a result, properly air sealing and insulating your attic can thwart ice dams before they can cause any damage.
