Heavy snowfall contributes to a lot of roofing issues, from leaks to dangerous collapses. If you live in the snowbelt and frequently have a lot of the white stuff, you need to take this into consideration when choosing a roof for your home. The best choice, under most circumstances, is a metal roof. Here's why:
Metal roofs eliminate the ice dam issue.
With an asphalt, cedar, or even slate roof, snow can pile up on the roof. As it melts, the water trickles down towards the roof's edge before re-freezing. This forms what is known as "ice dams." These dams can cause gutterstop bend, and they can work their way under the shingles, prying them away from the roof and leading to leaks. Ice dams are not an issue with metal roofs, since they're so sleek and slippery. Once the snow starts to melt, even just a little, it slides off the metal roof rather than staying in place and letting water trickle down.
Metal roofing reduces the risk of a roofing collapse.
As snow builds up on a roof, one of the main things you need to worry about is the roof collapsing under the weight of the snow. This is not a major concern with metal roofs for two reasons. First, snow tends to slide off the roof as discussed above. Only when temperatures are very, very cold outside will the snow actually accumulate on the roof. (It has to be cold enough to counteract the little bit of heat that escapes from your home through the roof and melts the snow and causes it to slide.) Second, metal roofing is lightweight when compared to other materials. So, you have a better starting point when it comes to weight. More snow can accumulate without there being a cause for concern than if you were to have a heavier roof.
Metal is impervious to moisture damage.
Months of exposure to wet snow can cause premature disintegration of an asphalt, cedar, or even concrete roof. Metal, however, stands up very well to this excessive moisture exposure. Most of today's metal roofs are made from alloys that won't rust or corrode. You can expect a metal roof to last between 40 and 70 years, and it will require few, if any, repairs during this time. Compare this to a traditional asphalt roof that might need to be replaced in as few as 12 years in a moist environment, and metal is obviously the better choice.Share

When I married my husband 10 years ago, I agreed to move into the ranch home he already owned. Initially, we planned to live in this house for five years and then after a few years of marriage we wanted to buy our dream home. After our wedding, many things in our lives changed. We both got different jobs. And we decided to transform the house my husband owned when we married into our forever home. To accomplish this task, we have begun a major renovation project. The first job on our list was a new roof. On this blog, I hope you will discover the best types of roofs to install on a brick home.
