Metal roofing is much more than a novelty that you see on affordable cabin building shows in Alaska. Factors such as life expectancy, metal roofing costs, maintenance, and overall aesthetic are all things to consider with metal roofing.
Read further to learn more about what metal roofing is, debunking common misconceptions, and everything you need to know and consider before installing a metal roof.
1. Metal Roofs are Not Noisier than Asphalt Roofing
A common misconception is that metal roofs are louder than the traditional asphalt roofing when it comes to rain or hail falling on them. When in reality metal roofing is no louder than any other type of roofing. When metal roofs are installed, typically it’s over a solid substrate that dampens the sound.
Furthermore, the attic and insulation, if installed correctly, should provide a sound barrier. From their home living spaces, occupants rarely notice any increase in noise levels with a metal roof installed.
2. Metal Roofs Do Not Attract Lighting
Another common misconception is that metal roofs are more susceptible to lightning strikes… this is far from true.
According to statistics conducted by the Metal Construction Association, “Metal roofing does not in any way increase the risk of a lightning strike.”
Furthermore, if metal roofing happens to get struck by lightning, it is less likely to combust than conventional roofing materials such as shingles or wood shakes.
But why is this hard to wrap your brain around, when in science class you learned metals attract electricity?
As the Metal Construction Association states, “Because metal roofing is both an electrical conductor and a noncombustible material, the risks associated with its use and behavior during a lightning event make it the most desirable construction available.”
In other words, the reason why metal roofs don’t attract lightning is quite simple, lightning seeks a path to the ground and metal roofing does not provide that path for lightning. This is why structures such as trees and telephone poles tend to attract lightning.
Metal roofs are isolated structures; they have no direct path to the ground that is inherent in their design. Therefore, according to the laws of science, there is no reason for lightning to strike metal roofing any more than asphalt shingle roofing.
3. Metal Roofing is Environmentally Friendly
In the U.S. alone, traditional roofing products contribute to an estimated 20 billion pounds of waste to American landfills a year.
On the contrary, metal roofing contributes zero waste to landfills.
Here are the facts of why metal roofing is environmentally friendly:
- Most metal roofing is made from up to 99% recycled aluminum and the majority is post-consumer consumption, such as aluminum from recycled cans
- The low weight of aluminum and metal roofing (compared to asphalt shingles) minimizes transportation costs
- The low weight also allows installation over existing roofs- no need to put time and energy into taking a roof apart
- 100% recyclable if the metal roof is ever replaced
- Can be integrated with most photovoltaic solar power systems

4. Metal Roofing is More Cost-Effective and Energy Efficient
Not only is metal roofing environmentally friendly, but it is also more cost-and energy efficient than asphalt shingles for many reasons. Some of these include:
Metal roofing has a longer lifespan than asphalt shingles.
On average asphalt shingles have a lifespan of about 30 years, in the right circumstances with no extreme weather conditions. While according to State Farm Insurance Statistics, metal roofs routinely have a longevity of 40-70 years.
Therefore, it’s very rare for homeowners to install more than one metal roof over the time period they live in their homes.
In contrast, homeowners will likely have to replace an asphalt shingle roof at least three or even four times over a 50-year period.
However, the cost of installing a metal roof can be more expensive than (sometimes even double), but overall it can save money in the long haul
Metal roofing reduces cooling costs.
Metal roofings unique reflective properties help keep the temperature of the surrounding environment from significantly affecting the temperature inside the home.
Unlike asphalt shingles, metal roofs reflect solar radiant heat instead of absorbing it. According to the Metal Roofing Alliance, metal roofs can reduce cooling costs by as much as 25 percent.
Furthermore, some metal roofing is coated with a special reflective coating to minimize heat gain, which can keep occupants comfortable inside their home without having to crank up the air conditioner.
5. Metal Roofing is More Durable Than Asphalt Shingles.
As stated earlier in the article, you know that metal roofing has a longer lifespan than asphalt shingles, but why is that?
One factor that has increased the popularity of metal roofing is that it is virtually fireproof. With the recent increase in wildfires, metal roofing has become a more popular choice.
Additionally, metal roofing is impervious to rot and mildew. Unlike asphalt shingles, water is unable to penetrate metal.
As well as, insects and termites can’t eat away metal roofing.
There are pros and cons to each type of roofing. Usually, the type of roof is contingent on the environmental factors specific to the location of your home. Keep these factors in mind the next time you need a roofing replacement or even when considering adding metal roofing over-top your existing roofing system.
