Metal Roofing is More Susceptible to a Lightning Strike—False
If your home were hit by lightning, your metal roof would disperse the energy safely throughout the structure. Moreover, a metal roof will not increase the likelihood of lightning striking your home. Since metal roofing isn’t combustible or flammable, it’s a low risk and desirable roofing option where severe weather is concerned, especially for lightning.
Metal Roofing is Noisier Than Asphalt—False
It is a common “old wives tale” that a metal roof will be noisier than other types of roofing. A study was conducted with a decimeter and is results show that a metal roof, when applied to solid decking/sheathing, is not noisier than an asphalt roof. However, when a vertical metal roof panel is installed over another roof by means of a “purlin” or strapping, the air space created will conduct an echo much like a drum. When installed with solid sheathing, a metal roof on your home will actually silence noise from rain, hail and bad weather, many times much better than other roofing materials.
WOW, our Kassel & Irons metal roof panel withstands a 2 1/2″ size hail stone In most cases, a metal roof can withstand decades of abuse from extreme weather like hail, high winds, and heavy snow. Today’s systems also have a 120-mph wind rating (equal to an F2 tornado), meaning your metal roof is also safe from wind gusts that can accompany hail storms.
Today’s metal roofing systems are built to last. Steel metal roofing has a “metallic coating” made of either zinc (G90) or a combination of zinc and aluminum (Galvalume), which is a less expensive coating process. This metallic coating prevents rust from forming and is bonded to the steel at the factory. Paint is then applied over the metallic coating to provide the long-lasting color homeowners desire.
Many people think you can’t (or shouldn’t) walk on a metal roof, but the truth is that you can safely walk any metal roof without damaging it. Before you walk your roof, however, we recommend you talk to your installed or roof manufacturer first. They will have the details on how to walk the particular roof you have, based on the style you chose and your roof pitch.
