This is a common problem for homeowners in Wisconsin during the winter months. It occurs when snow on the roof melts and then refreezes at the edge of the roof, forming a dam of ice. This dam prevents the melting snow and ice from draining off the roof, which can lead to water infiltration and damage to the roof and interior of the home.
One of the main causes is poor insulation and ventilation in the attic. If the attic is not well insulated, heat from the living spaces below will rise and melt the snow on the roof. If there is poor ventilation in the attic, the warm air will become trapped, causing the snow to melt and refreeze at the edge of the roof.
Another factor that contributes to ice damming is the type of roofing material. Homes with flat or low-sloped roofs are more prone to ice damming than those with steeply-pitched roofs. This is because the snow and ice are more likely to melt and refreeze at the edge of a flat or low-sloped roof.
There are several ways to prevent ice damming in Wisconsin. One of the most effective methods is to ensure proper insulation and ventilation in the attic. This can be done by adding insulation to the attic floor and ensuring that there are enough vents to allow the warm air to escape.
A temporary fix is to install electric cables or heating elements that are installed along the edge of the roof to melt the snow and ice and prevent it from refreezing.
It's also important to keep the roof clear of snow and ice. This can be done by using a roof rake to remove the snow from the edge of the roof, or by hiring a professional to do it.
Homeowners should also be aware of the signs of ice damming, such as water stains on the ceiling or walls, and take immediate action to address the problem. This may include removing the ice dam, repairing any damage to the roof or interior of the home, and taking steps to prevent future ice damming.
In conclusion, ice damming is a common problem for homeowners in Wisconsin during the winter months. It is caused by poor insulation and ventilation in the attic, as well as the type of roofing material. To prevent ice damming, homeowners should ensure proper insulation and ventilation in the attic, install a roof deicing system, keep the roof clear of snow and ice and be aware of the signs of ice damming and take immediate action.
