Metal roofs are an excellent investment for your home. A properly installed metal roof can last up to 70 years, with the exception of metal roofs bolted with exposed fasteners, which should be replaced approximately every 15 to 20 years. The environmental impact of manufacturing metal roofing products is comparable to that of the same measurements in the production of asphalt shingles. The results of a study showed that metal roofs renovated with vertical joints recover between 85 and 95% of the costs, amounting to 1% to 6% gains in resale value compared to houses covered with asphalt shingles.
Metal roofs with flat joints can be more expensive to manufacture and install, but their interlocking joint design is one of the best options available. From indoor living spaces, residents rarely notice an increase in noise levels when a metal roof is installed. Commonly used metal roofing materials, such as steel and aluminum, are designed to maintain paint finishes well. And, if you're hoping to sell your house, a metal roof will definitely increase your home's curb appeal.
Metal roofs are isolated structural components, with no direct path to the ground inherent in their design. Industry studies show that metal roofs reflect solar radiant heat, which can reduce cooling costs by 10 to 25 percent. While metal roofs are considerably more durable and maintenance-free than asphalt shingles and other forms of roofing, they are not indestructible. You should always consult at least with a professional, however, it is possible to maintain a metal roof without the help of one.
As stated in the bulletin, since metal roofs are both an electrical conductor and a non-combustible material, the risks associated with their use and behavior during lightning make them the most desirable construction available. According to a technical bulletin from the Metallurgical Construction Association, metal roofs do not in any way increase the risk of lightning. Make sure that your metal roofing product is tested, labeled and included in a testing organization, such as UL, FM Approvals, or Intertek, to meet rigorous classification requirements for wind, fire and impact resistance. A metal roof will protect you against weather and fire, but if not installed properly, it may not work as you would expect and could even cost you a lot of money in water damage. Metal roofs generally cost a little more per square foot than asphalt shingle alternatives, sometimes at a magnitude of two or three.
