Winter can cause problems for your home in a few different ways. For one, winter storms can generate high winds that can rip wooden or asphalt shingles right off of your roof. For another, snowmelt can freeze over your eaves and create dams that allow water to run under your shingles. Finally, snow can build up on your roof until it overwhelms and collapses your roof. If you know that you will have to contend with harsh winters, metal should be your first choice for roofing material, and here's why.
Asphalt shingles are the least expensive roofing material on the market and thus help you to save more money on initial costs than you could with metal roofing, but they leave your home exposed to the risks described above; thus, you can easily pay more money to maintain your roof than you save because, as will be explained, metal roofing will protect your home from the worst that winter can throw at you.
Metal Roofing and Ice Dams
Metal roofing comes in panels that extend from the ridge of your roof to the eaves. Thus, if ice dams start to form on your roof, any water that builds up behind the dams will not be able to run under your roofing.
Metal Roofing and Snow Collapse
Some roofing materials such as asphalt or wood shingles will have a rough surface that creates enough friction to prevent snow from sliding off of your roof. Thus, as winter winds on and on, snow can build up on your roof, and the risk of collapse just increases. Metal roofing, on the other hand, has a smooth surface that will allow snow to slide off of your roof before it can build up enough to cause problems.
Metal Roofing and Wind
Metal roofing is fastened to your roof with decking screws, which will not pull out as easily as the nails that hold shingles in place. Thus, metal panels can stand up to high winds without blowing off of your roof.
Because of how durable metal roofing is, it will help to keep your maintenance costs low. If you buy a roofing material that is susceptible to weather damage, you can end up paying a lot of money to repair your roof every time it is damaged by a storm. On the other hand, because a metal roof better protects your home from weather damage, you will end up saving more money in the long run.
