Snow can cause problems for a roof in a few different ways. For one, snow that melts over the main body of your roof can freeze over the eaves and create ice dams. For another, snow can build up over the body of your roof and create enough weight to cause the structure of your roof to collapse. In order to prevent these problems from destroying your roof, you need to choose a roofing material that will stop snow before it can pose a threat to your home. 

Metal Roofing versus Ice Dams

When snow melts over the main body of your roof, it can freeze over your eaves. As layer after layer of ice builds up on your eaves, the ice can dam up water, and as water pools up behind the dam, it can run under your shingles and cause serious water damage to your home. Metal roofing comes in panels that run from ridge line to eave. Because you have one continuous panel of roofing, melt water cannot run under your roofing. 

Metal Roofing versus Roof Collapse

If you choose a roofing material that has a rough surface, it will create a lot of friction between snow and your roof. This means that even as snow melts, it will remain in contact with your roof. If snow falls faster than the heat escaping from your house can melt it, snow will accumulate. The weight of the snow can overwhelm your roof, especially if you have an older house. You can climb up on your roof and shovel snow off, but you put yourself in harm's way. A metal roof has a low-friction surface that will allow snow to slide off your roof before it has a chance to cause collapse. In fact, you shouldn't have to even worry about ice dams forming on your roof. 

If you live in an area that gets a lot of snow, then you should seriously consider installing a metal roof. Even if you don't get a lot of snow where you live, a metal roof can protect you from high winds and other extreme weather. Not only can a metal roof protect you from extreme weather, but it can improve the looks of your home. If you are not sure about installing a metal roof on your home, you should at least talk about installing a metal roof with a residential roofing contractor to determine if installing one is right for your home.
