Concerned about how your roof stacks up against winter’s extreme weather? Whether you’re likely to experience heavy wind, hail, snow, or fire, there’s no better choice than a metal roof.
Heavy Wind and Hail Storms
In most cases, a metal roof can withstand decades of abuse from extreme weather like hail and high winds. Today’s systems also have a 150-mph wind rating (equal to an F2 tornado), meaning your metal roof is also safe from wind gusts that can accompany hail storms.
This is simply not the case with other roofing materials. Non-metal roofing material begins to deteriorate as soon as it’s exposed to elements like severe storms and high winds. A metal roof will never deteriorate, and can withstand most everything Mother Nature throws its way.
The video below is from WROC in Rochester, NY, and it highlights an all-too-common scenario. It details a dangerous storm that caused damage to asphalt roofs in its path, while the metal roof protects and withstands any potential destruction. The video then provides some key points about what you need to know about metal roofs.
Snow and Ice
Most metal roofs have a fairly smooth top surface. When the sun shines, heat from the sun passes through the snow, hits the metal, and is reflected back outside. The sun heats up the metal roof allowing the snow to melt over the entire roof surface. The snow and ice will melt from the bottom creating the opportunity for the snow and ice to shed more quickly than other roofing materials.
Ice can be just as hazardous as snow to your home. Icicles hanging along the eaves of your house may also lead to ice dams: thick ridges of solid ice that build up along the eaves. Dams can tear off gutters, loosen shingles, and cause water to back up and pour into your house. A homeowner who doesn’t have a properly insulated attic could be faced with an ice dam upstairs. Heat from the attic melts snow on the roof, and the melted water pools and gets in the house. The easiest way to avoid heavy snow loads and ice dams is to consider installing a metal roof.
While it may seem only relevant for the West Coast, wildfires are a threat to communities all across North America. Metal roofs are naturally very tough and highly resistant to fire damage. Fire will not penetrate a metal roof. Metal roofing materials interlock, forming a protective barrier that other roofing materials do not provide.
Most forest fires decimate residential communities through burning pine needles and other debris blown from roof to roof. More conventional roofs, such as asphalt, catch fire relatively easily and the home is at danger of burning to the ground. A metal roof is not combustible, so it doesn’t provide additional fuel for the fire. That’s why many fire chiefs recommend a metal roof. You may also notice that a lot of fire stations have metal roofs.
