Debunking the Myths of Metal Roofs
For years, metals roofs have been surrounded by myths, such as they are loud when it rains, you can’t walk on them and they are easily dented by hail. Howard & Sons Roofing debunks those myths and sheds some light on the benefits of metal roofs.
7 Myths About Metal Roofs
Myth – THEY’RE REALLY LOUD WHEN IT RAINS
Truth – Maybe you’ve been in an old barn when it’s raining, and you noticed the sound of the rain on the roof was just deafening. While that’s true, you shouldn’t expect the same from a house with a metal roof. This is because metal roofing on a house is paired with a roof deck that adds structure to your roof, and insulates against sound. The roof deck and the insulation that fills it work together to muffle the noise no matter what type of roofing lays on top. So, the fact is that metal roofs are just as quiet as asphalt, tile or clay roofs.
Myth – METAL ROOFS ATTRACT LIGHTNING
Truth – The fact is, lightning strikes whatever it’s closest to. Lightning is an excess of electricity that’s looking to discharge, and in the case of lightning that heads towards earth, it’s looking to discharge into the ground. The quickest way to do that is to find the object closest to it. While metal is a conductor, it does not attract lightning, and the truth is that metal roofs are one of the best roofs to have in the event that your home is struck by lightning. The metal woks to disperse energy safely through the structure of your home, and more importantly, metal is noncombustible. This means that if your home is struck by lighting, a metal roof will not catch fire, something that can’t be said for many other materials.
Myth – METAL ROOFS ARE EASILY DENTED BY HAIL
Truth – While hail is not an everyday occurrence in San Diego, the occasional hail storms that occur can be damaging and costly to homes. Recent reports show that hailstorm costs are increasing in the United States, averaging $8 billion to $10 billion in damage annually and accounting for 70 percent of insured loss from severe storms. Quality metal roofs often earn a Class 4 impact-resistance rating—the highest level of protection against hail damage available—based on the insurance industry Underwriters Laboratory ranking called the UL 2218 standard. That means, installing a metal roof can help reduce hailstorm damage and prevent costly repairs and replacement.
Myth – YOU CAN’T WALK ON METAL ROOFS
Truth – Metal roofs are just as walkable as any other type of roof. The important thing to remember is that the risks of walking on a metal roof are pretty much the same as risks of walking on any other type of roofing material. If your main concern for walking on the roof is maintenance, keep in mind that metal roofs require little to no maintenance once properly installed.
Myth – METAL ROOFS HEAT UP YOUR HOUSE
Truth – While even basic, unpainted metal roofs will reflect more solar radiation than asphalt roofs, low-glare metal roofs with the proper colors and coatings reflect most non-visible, infrared and UV rays. These are the kind that produce the most heat and are the most damaging. And by emitting as much as 85% of solar heat gain to help keep homes cooler, even darker color metal roofs will help lower home temperatures during sizzling summer weather. Metal roofs also can help save energy by lowering roof temperatures by as much as 50%. In fact, the Environmental Protection Agency estimates that an Energy Star labeled roof can lower roof temperatures by as much as 100 degrees Fahrenheit.
Myth – METAL ROOFS WILL RUST
Truth – Today’s metal roofs are bonded with a galvanized coating that’s constructed of advanced alloys made to resist rusting. They’re then painted with special roofing paint made to withstand the effects of weathering, which means that once you install a metal roof, it will remain rust-free for decades.
Myth – METAL ROOFS ARE TOO HEAVY FOR MY HOUSE.
Truth – You’ll be surprised to learn that a metal roof is, on average, 50% lighter than an asphalt shingle roof, and 75% lighter than concrete tile, fiber cement shakes and slate roofs. With metal roofing, weight on a structure is never an issue.
