Each year thousand of homeowners are faced with the pricey decision to replace the entire roofing system on their homes. On average, the lifespan of a non-metal roof is 10 to 17 years. On the contrary, a metal roof (commonly composed of tin, aluminum, and cooper) on average will last at least two to three times longer. In recent years, metal roofing system technologies have drastically improved providing homeowners with numerous stylish options to consider; many of which provide opportunities to claim money-saving tax credits. Despite the various advances in such technology, the following myths continue to pervade the marketplace.
Metal Roofing Is Not Energy Efficient
False. Metal roofs actually increase the energy efficiency within a home. Recent studies by the Florida Solar Commission suggest that metal roofs reflect up to 70% of the sun’s rays which effectively reduces the heat absorbed when compared to a traditional roof. The reduction in the heat absorbed by the roof results in a cooler home which translates to lower energy cost related to air conditioning.
Metal Roofing Is Expensive
Meanwhile it is true that metal roofs may cost more initially, the long-term costs are generally less than other roofing material alternatives. The long-term benefits are derived from cost savings due to the low cost of maintenance and the lower incidence of repair needed to metal roofs. Additionally, for a limited time there is a federal credit available for homeowners choosing to install metal roofing systems on their homes. Note also that some states sponsor energy efficiency programs that offer financial incentives; however, the requirements may be different that those required for federal purposes.
Metal Roofs Attract Lighting
Despite popular belief, having a metal roof does not increase the likelihood of a home being struck by lighting. In fact, numerous studies have been done to prove that lighting is attracted to the highest surrounding objects regardless of the structure and its composition. Since metal is non-combustible, unlike wood and other roofing materials, if lighting were to strike a metal roof it would simply spread the charge over the surface area rather than ignite the roof.
Metal Roofing Systems are Noisy
Modern metal roofing systems are often comparable if not better than traditional roofing materials when installed correctly in regards to the noise emitted related to weather phenomenon (i.e., rain, wind, hail, etc).
