Metal Roofing Myths
Metal roofs are more likely to be struck by lightning
Metal roofs have been demonstrated to be no more likely to be struck by lightning than any other roof. In fact, metal roofs are better able to absorb a lightning strike and distribute the electricity across the roof. Additionally, metal is noncombustible and will not catch fire if it is struck by lightning. If a lightning does strike your home, a metal roof will safely dissipate the electric charge even if it is not grounded.
Metal roofs are noisier than other roofs during rain
This is a common misconception based on older metal roofs installed over barns with nothing to insulate the sound produced by the impact of rain. Modern metal roofs are installed over plywood, solid sheathing or your existing roof. This innovation allows metal roofs to suppress the noise generated by rain drops colliding with your roof. Onestudy even suggests that the noise levels of metal roofs and other roofing materials during storms are comparable.
Metal roofs are expensive
Metal roofs are actually less expensive than asphalt shingle roofing systems because they require fewer repairs and less maintenance over their functional lifespan. In addition, metal roofs can help you reduce your cooling bills during the summer by up to half while simultaneously increasing the value of your home. If properly installed by a licensed professional, a metal roof can last a lifetime, and you’ll never have to install another roof again.
Metal roofs rust easily
Modern science and technology have largely driven the development of metal roofing beyond the concern of rust and oxidation. Steel roofing is designed with a coating of zinc or aluminum, which is bonded to the steel. In addition, specially designed high-performance primers and paints are applied to the roof that serve as an added safeguard that prevent rust from occurring. These paints come in virtually every color and can satisfy the particular taste of any homeowner.
Metal roofs may be easily dented
Today’s metal roofing systems are designed to withstand the abuse of extreme weather and daily exposure to the elements without failure. The impact of hail storms is typically not enough to dent metal roofs. Moreover, wind damage should not be a concern either because contemporary metal roofing standards dictate that metal roofs be capable of withstanding winds of up to 155 mph. In fact, metal roofs stand up to the strain of hurricanes better than any other roofing system. It is not uncommon for our roofers to see an undamaged metal roof neighboring several roofs that have had their shingles removed after a hurricane or severe storm.
