The type of roofing you use on your house can affect everything from your home's energy efficiency to its ability to resist extreme weather. While you might be tempted to focus on the initial cost of your roof, this might not be the best approach for getting the optimal performance from your roof. Asphalt roofing is inexpensive, but you can get better performance from your roof if you buy a metal roof.
Metal Roofing Resists Extreme Weather
Many roofing materials are adhered to a roof with nothing more than roofing nails. While this is a good way to adhere the roof to the decking, there is a better way. Metal roofing uses decking screws to affix metal panels to your roof. These screws will bite into your roof and hold it in place in winds that would rip asphalt shingles right off of your roof. Furthermore, metal can resist hail, sparks, and other extreme weather events.
Metal Thwarts Ice Dams
When snow melts over a roof, the water thus created will run down the roof. Because the eaves of the house have air flowing underneath them, the water will freeze over the eaves. Once layers of ice form over the eaves, they create a dam that can prevent meltwater from running off of your roof. If you have shingles, the water can run under the shingles and create leaks. However, if you have solid metal panels, the water cannot run under your roofing. An even more important benefit is that the low-friction surface of a metal roof will allow the snow to slough off, so you don't typically have to worry about ice dams in the first place.
Metal Defeats High Energy Costs
Metal roofing will deflect the sun's UV rays away from your home before it has a chance to heat up your roofing, which in turn will heat up your home. A good metal roof can reduce your cooling costs by up to 40%.
While a metal roof will cost more initially than an asphalt roof, one of the most popular and least expensive roofs on the market, you will end up saving yourself money over the life of your roof. Thus, if you can afford the initial expense of installing a metal roof, you will do yourself a favor by installing one. When choosing a roof for your home, you need to make sure that you don't focus overmuch on the initial cost of roofing installation so that you can do yourself a favor over the long run.
