Blizzards, ice storms, and freezing rain have historically been common in Wisconsin. According to the Old Farmer's Almanac, Wisconsin will see one of the coldest winters in years this year. Ice dams on roofs are projected to rise, causing serious harm if they build beneath your roof! And, if you live in a region where ice dams are widespread, you should be aware of their potential for roof damage before winter begins.
What Exactly Is An Ice Dam?
An ice dam is a deposit of ice at the edge of the roof that prevents melting snow from draining off. Water also backs up and leaks into attics, walls, and crawl spaces as a result. When you detect black or brown streaks on your outside walls, this is usually due to water seeping behind the walls and producing ice dams.
How Do Ice Dams Affect My Home?
If water accumulates behind the ice dam, it can seep into the structure and insulation of your home, causing severe damage. Mold development in walls and ceilings is a problem as a result of water leaks. An ice dam also stops runoff from draining away, which can lead to roof collapses as well as damage to attics and walls.
What Causes Ice Dams?
Ice dams may occur on any roof, but residences with uninsulated or single-pane glass sections, such as attics and roof vents, are more vulnerable. Ice dams can be caused by a number of reasons, including:
Inadequate insulation and air sealing in attics and walls
Poor ventilation
Crawl areas that are wet
Roofs that are improperly pitched, especially when there is insufficient roof insulation.
Inadequate attic or roof ventilation
Unsealed wall and ceiling cavities, gaps around service pipes and chimneys, recessed lighting, electrical outlets, and crevices around window and door frames all allow air to enter and exit the property.
What Can I Do To Prevent Ice Dams?
The best line of action is to address the conditions that lead to the creation of ice dams. Here are some ice dam prevention tips:
Caulk or expanding foam should be used to seal cracks, gaps, and openings along external walls, roofs, and ceilings.
Increase attic insulation.
Properly ventilate attics to keep heat in the house throughout the cold winter months.
Ventilate the attic area properly to prevent moisture buildup.
Install gable vents beneath insulated roofs to trap cold air and moisture. Increase insulation at roof lines and around service pipes and chimneys to prevent cold air from leaking into the home.
Make sure the roof has appropriate ventilation (vents, fans, etc.) to remove damp exterior air from the home.
Roof repairs should be avoided during exceptionally cold weather unless absolutely required.
Install a de-icing wire or an ice barrier made of plastic or aluminum below the edge of your roof to prevent snow accumulation.
During cold times, avoid using attic fans to exhaust the roof.
