Although the roofing material that you use can have a big effect on your energy usage during the hot summer months based on whether it retains or reflects the sun’s heat, you may not know that it can also have a big impact in winter and that this can actually be more important than the summer impact when you live in a cold climate. If you have long harsh winters in your area but you don’t have long hot summers, your roof’s winter characteristics may be one of the most important things about it. Here are three characteristics of metal roofing that make it a good choice in areas that have harsh winters.
Metal roofing can self-clean
Because metal roofing doesn’t grab onto snow and ice like asphalt shingling, which is more textured, the snow can easily slide off of a metal roof and eliminate the need for snow removal. This means you won’t have to worry about snow piling up on your house and caving the roof in after a big blizzard, even if you live in the North near Canada.
This slipperiness also means that you could have snow dumped on you when you’re walking under the eaves of your roof, so if you’re worried about large amounts of snow engulfing you when this happens, you can easily have snow guards installed. Snow guards, depending on their design, generally either retain snow so you can choose when it comes down or break up large sheets of snow into smaller quantities before it falls to the ground.
Metal roofing can reduce ice dam leaks
If you’ve ever had an asphalt roof in the winter, you may know that it’s prone to ice dam leaks. These are caused by snow building up on the roof, insulating the roof so that any heat that escapes from the house is trapped with the bottom layer of snow. This layer then melts, and the water that’s held in place by the rest of the snow and ice can more easily find its way up under your shingles because it has nowhere else to go. Metal roofing is less prone to this because the snow slides off the roof rather than staying there and trapping in heat.
Metal roofing is more likely to hold up to wind
Metal roofing has been rated as one of the most wind-safe types of roofing. It’s still possible for strong winds to rip a metal panel off your roof, but it’s much less likely. You can make it even less likely by using strong, wind-safe fasteners like rink shank roofing nails, which make it even less likely for your roofing to part company with your roof deck. Whether your wind comes in the form of a winter storm or as a summer thunderstorm or even hurricane, metal roofing can be more reliable and less vulnerable than asphalt.
These characteristics show that metal roofing can be great in the wintertime as well as in the summertime. Year-round benefits can add up to a major advantage if you switch to metal at your next roof replacement.
