Verona Roofing: Article About Cold Roofs Prevent Ice Dams
Long winters with freezing temperatures and plenty of snowfall can be the perfect combination of factors to cause the formation of ice dams on a roof. While icicles hanging from the eaves might seem like a normal part of life during the coldest months of winter, they can also be an important sign that there is a problem with your roof. Leading Verona roofing contractors recommend that homeowners have their roof inspected prior to the cold winter, especially if they typically see ice dams or icicles along the edge of their roof during the winter.
One of the first things a roofing contractor will check is whether there is sufficient insulation in the attic. Insulation is often thought of as an important part of keeping the cold out, but it is also used to help ensure that the warmth from the home's interior doesn't rise and heat the underside of the roof. When the roof gets warm, snow standing on the outer surface can begin to melt from the underside. This puts into motion a very serious situation that can lead to the formation of ice dams. When ice dams form, water damage is often present as well.
When snow melts unevenly on the roof, such as when warm spots in the attic heat the roof from the underside, the water from the melted snow travels down the slope of the roof.

In the spring, when the entire roof is melting at an even rate, the roof is all one temperature, and there is generally not a problem. However, in the midst of winter, warm sections on the roof melt the snow in those areas only. Other sections of the roof, such as along the eaves, remain cold. As the water tries to drain off the roof, it hits standing snow and a cold roof and simply freezes along the roof's edges, gutters or valleys. As this process continues, water often backs up and creates water damage to the roof, to the attic and, eventually, to the interior of the home.
While proper insulation is often an excellent way to prevent premature heating of the roof, good ventilation is also important. An attic or soffit fan can be used to help provide circulation and keep the attic and underside of the roof cool. With a cool roof, any standing snow on the outside of the roof will not begin to melt prematurely, putting a stop to the destructive pattern of ice dams.
