Even the highest quality commercial roof will only last for a while. At some point, facility managers and commercial property owners may face decisions about what type of roofing to use for a renovation project. Metal roofing is often an excellent option for properties of all sizes, providing impressive benefits in terms of durability, cost savings, energy efficiency, and more. However, every roofing material has drawbacks, too, so the whole picture should be taken into consideration. Let’s dive into the pros and cons of metal roofing so you can make an informed decision about the ideal coverage for your commercial property.
Pros of Metal Roofing
Long-Lasting
According to a top-rated commercial roofing company in Waynesville, NC, a standing seam metal roof can last an incredible 30 to 50 years. Other types of metal roofs can last even longer – up to 70 years! Compare that to asphalt-based roofing, which typically has a lifespan of 20 years at best. To put this in perspective, an investment in commercial metal roofing is likely to last long past the day you retire!
Durable
What kind of weather events can you expect to see in your region? Metal roofs are considered extremely durable against wind, withstanding gusts of 140 mph, as well as thick snowfalls and ice, which slice right off the smooth slope. There’s no need to worry about rusting during the winter months, either, since not all metals are prone to oxidation. Many metal roofs are made from non-rusting metals like zinc, aluminum, and tin. Metal roofs comprising steel and iron are coated with a rust-proof zinc or silicon finish.
Safe Against Lightning
Contrary to popular belief, metal roofs are not vulnerable to lightning. The misconception comes from the idea that metal conducts electricity. However, the goal of lightning is always to strike the ground. It doesn’t target objects containing the most metal – but objects with the greatest height and a continuous path to the ground.
Energy Efficient
While some commercial roofing materials absorb light, metal reflects it. Heat from the sun’s UV rays and infrared light won’t transfer through the roof into the building. As a result, your building’s cooling systems won’t have to struggle to keep up. Metal roofing is reportedly associated with up to 25% savings in cooling costs.
Environmentally-Friendly
One of the best ways today’s businesses can invest in tomorrow is to make environmentally-conscious business decisions. Metal roofing is 100% recyclable at the end of its lifespan. As such, new metal roofing is typically made from at least 25% recycled materials. Compared to asphalt shingles, for instance, which are made from fossil fuels and end up in landfills, metal roofing is the most ethical choice for this reason alone.
On top of that, because metal roofing lasts longer than other roofing systems, fewer materials will be used over time, and fewer installations (which produce pollution and fumes) will need to occur. Metal roofs are also an excellent foundation for solar panels, rooftop gardens, and rainwater harvesting systems.
Cons of Metal Roofing
Affordability
Metal falls into the category of high-end roofing materials. The metal used for roofing generally costs anywhere from $1.20 to $9 per square foot. At the higher end of this range, you may spend ten times more on metal roofing than another material. Still, at the lower end, metal roofing is comparable to other high-quality products. However, the cost of installation and labor is much higher as well. The cost may be worth it, depending on the size of your building and how much you stand to save in energy-efficient benefits and increased property value.
Noise
Do you love the tinkling sound of rain on a metal roof? If so, the noise level of metal roofing may actually be a benefit. On the other hand, it may be extremely loud or distracting in the context of business operations. Extra layers of sheathing and insulation can help mitigate the sound issue, but this will increase costs, too.
Low-Grade Metal
Low-grade metals are often thinner and, therefore, more prone to denting, damage, and rust. On the flip side, higher grades are more resilient but also more expensive. In addition, metal roofing panels expand and contract with the temperature fluctuations across the seasons – as they are designed to do – but this movement puts strain on the fasteners. After several years, they may deteriorate or break away, opening up small areas where water can seep through.
In Conclusion
Overall, metal roofing has more pros than cons for commercial properties. While the initial investment may be higher than other types of roofing, metal roofs last much longer. They are also durable, safe, and energy efficient. In addition, metal roofs are becoming increasingly popular due to their environmental friendliness. Metal roofs have their fair share of drawbacks as well, such as noise and performance issues. However, these can typically be mitigated with high-quality installation and regular maintenance. If you’re considering a new roof for your commercial property, metal is definitely worth considering.
