Metal Roofing Myths Debunked

Posted on: 1 November 2021


One of the most durable roofing materials is metal. This material is also strong and can withstand extreme weather conditions better than most roofing materials. If you are thinking of investing in a metal roof, here are some myths you shouldn't believe.

Metal Roofs Make Your House Hotter During Summer and Cooler During Winter

Metal reflects the sun's energy away from your home. On the other hand, asphalt shingles tend to absorb the sun's energy and transmit the heat to your home. 

Consider the metal hood of your car. During hot weather, the hood of the car cools quickly when it is parked in the shade. This demonstrates that metal doesn't make your home hotter during summer. During winter, metal is an insulator. As such, it keeps warm air circulating in your home.

Metal Roofs Attract Lightning

Many people believe that their metal-roofed homes have a high chance of being struck by lightning. In fact, metal roofs protect your home from lightning damage because they are non-combustible. Factors that influence lightning strikes on buildings are area topography, building height, building size, and thunderstorm frequency.

Buildings located on elevated areas like hilltops are more susceptible to lightning strikes because they are near the strike area. Also, tall buildings have a higher risk of being struck by lightning than short ones. Furthermore, if a building covers a large surface area, it is more likely to be struck by lightning. Lastly, in areas where thunderstorms occur frequently, homes are more vulnerable to lightning strikes.

Metal Roofs Rust

Metal roofs don't rust if they are coated with zinc or aluminum. Rust only occurs on unprotected metal. 

Many metal roofs are made of rust-resistant alloys like galvanized steel and galvalume steel. Galvanized steel is coated with zinc. Zinc protects metal from the components that promote corrosion. Galvalume steel combines both zinc and aluminum. It is more durable and resistant to rust than galvanized steel.

Metal Roofs Are Easily Susceptible to Hail Damage

Many homeowners worry that hail storms will dent their metal roofs. Fortunately, metal roofing is highly resistant to hail than most roofing materials. 

Some metal roofs come with warranties that guarantee the roofing panels will not be damaged by hail. In fact, if you want to protect your home against hail-related water damage, you should invest in metal roofing.

While metal roofs are more expensive compared to other roofing materials, they are a durable and energy-efficient option. With a wide variety of metal roofs in the market, you will be spoilt for choice when shopping for metal roofing. Make sure you consult an experienced roof contractor for advice on the most appropriate metal roofing options for your home. For more information, contact a company like Alliance Exteriors.
