Metal shingles are often rated to withstand winds of over 100 miles per hour, and are rated for fire resistance. The Metal Roofing Alliance (MRA) reported that studies conducted by the Insurance Institute for Business & Home Safety (IBHS) acknowledged that all roof types can sustain some cosmetic damage depending on hailstorm severity, but “metal roofing performed best and was much less likely to puncture as compared to asphalt, withstanding even golf ball-sized hail stones without compromising performance.”Īnd metal roofs stand up well to other types of extreme weather. Many metal shingles are rated Class 4 for Impact Resistance by the UL testing group. Metal roofs are actually some of the most resilient roofing options when it comes to hail. Some metal shingles are stamped and shaped to look like other types of roofing, like wood shake, stone slate and clay tile such as the MetalWorks steel shingle produced by major roofing manufacturer TAMKO Building Products. Manufacturers have gone from standing seam metal roofs to creating metal shingles in a variety of colors that would make an attractive covering for any home. But as metal roofing’s popularity has grown, so has the technology to make it an excellent choice for residential structures. Metal roofs have traditionally been associated with industrial buildings, or outbuildings like sheds and barns. There are many other factors that influence the actual chance of a lightning strike." Myth # 3 – Metal Roofs Are Ugly "In fact, the presence of a metal roof really shouldn’t statistically increase or decrease the chances of a lightning strike. "Research shows that the material used in roof construction does not influence the risk of a lightning strike," says Karl Hielscher, MCA’s executive director in a press release. The factors that do affect lightning strikes include topography of the surrounding area, the height and size of the building and the frequency and severity of storms in the area. The Metal Construction Association has released several technical bulletins outlining research that shows metal roofs are no more likely to be struck by lightning than other types of roofing. In reality, residential metal roofs are fastened to the roof deck, not open rafters, and are able to be applied over multiple layers of old asphalt shingles so the sound insulation between the metal shingles and your ears could reduce the noise to potentially be less than more traditional forms of roofing. One of the biggest misconceptions of metal roofs is that they are loud during a rainstorm and unbearable during severe weather, like repeatedly dropping an object on tin.
