Ice Dam Prevention

Wisconsin winters are especially snowy and cold, which can be taxing on your home. Icicles and ice dams that form along the edge of your roof can cause significant damage to your home’s exterior. Luckily, they can be prevented with insulation and air sealing by the ice dam prevention contractors at Wisconsin Home Improvement.

What is an Ice Dam?

An ice dam is a build up of ice that blocks gutters and restricts melting snow from draining off your roof. If your attic is not well insulated, heat can escape from it during the winter and melt the accumulated snow. As the melted water begins to move towards the edge of the roof, it refreezes. This causes blocks of ice to form and creates ice dams and icicles. Ice dam removal is difficult and must be done regularly because they can wreak havoc on your home’s gutters, siding, roof and attic. They can also lead to roof leaks and water damage inside your home.

How to Prevent Ice Dams from Forming

During the winter, escaping heat from your attic can melt snow that’s accumulated on your roof. As the melted water begins to move towards the edge of the roof, it meets a colder area that then refreezes it. This causes blocks of ice to form and create ice dams, including icicles which hang from your gutters and roof.

Preventing Ice Dams

Preventing ice dams is much more effective than trying to remove them. While keeping your gutters clean and raking your roof are helpful, the best ice dam prevention includes:

Air Sealing

Air sealing will help with ice dam prevention because it will reduce the amount of warm air that gets into your attic. This will keep the snow on your roof from melting, and the heat in your home where it belongs. As an added benefit, air sealing will also lower your energy bills and keep your home more comfortable. 

Attic Insulation

Insulation acts as a thermal barrier for your home, preventing heat transfer. Attic insulation prevents ice dams by reducing the melting and refreezing effect that creates them. Improving your attic insulation also enhances the effects of air sealing, which prevents ice dams while keeping your home more cozy and energy efficient.

    I really feel compelled to give a "shout out" to everyone I have come into contact with at WHI. First off - Jody. You are so friendly and helpful on the phone, forgiving me for my inability to "on-line sign", switching up of dates, declining work and then changing my mind.

    Steve, just a side note and I would not send this if it was not completely true - Mike and Pete were both fantastic. I was impressed. We had just had other major construction and have many comparatives for the work WHI did. I would come home and never know they had even been there.
