Metal roofing has recently became a viable option for nearly all homes. Check out on these 7 surprising things about putting on a metal roof.

Are you looking to install a metal roof in your home or commercial building, but aren't sure if it's the right choice for you?
Metal roofs are a great option for all types of buildings. However, before you install a metal roof, there are some things you need to know.
Check out this guide to discover the top surprising things you need to know about putting on a metal roof.
- Metal Roofs Can Be Installed on Top of Existing Roofs
One thing that most people don't know about metal roofing is that it can be installed right on top of your existing roof, just as long as local codes allow it.
This means that you don't have to deal with tearing off shingles or undertaking any other time-consuming tasks that come with removing a roof. While it's definitely ideal to remove the shingles if you can, tearing off shingles is often a messy job that will raise the cost of installation.
The only problem you need to watch out for when installing a metal roof on top of an old roof is trapped water vapor. If moisture gets trapped between the old roofing and the new roofing, it can build up and cause mold and rotting.
However, to eliminate this potential problem, your roofers can install a vented metal roof. Or, they can install the roof over furring strips. These strips raise the metal so that there's enough air ventilation between the layers.
Before you have your metal roof installed over shingles, make sure you check with your local building codes. Some jurisdictions require you to completely tear off your old roof before installing a new one.
- Metal Roofs Don't Attract Lightning
Many people are nervous about installing metal roofs on their homes or metal buildings because they think it'll attract lightning.
However, this is not the case. There's no evidence that shows that metal roofing increases the chance of a lightning strike. Not only that, but metal roofing is also less combustible than other roofing materials. This means that should it get struck by lightning, your roof and home are less likely to suffer from severe damage.
Also, not only is metal roofing resistant to lightning, but it's also resistant to fire, insects, and rot. Many types of roofing materials suffer from termite damage. However, termites are unable to eat through metal roofing.
- A Metal Roof Can Be a Cost-Effective Option
If you're on the hunt for cost-effective roofing material, metal may be your best bet.
Typically, a metal roof comes with a warranty of around 30 years. However, most metal roofs are known to last much longer if they're properly maintained -- oftentimes, up to 50 years or more.
It's very rare to have to install more than one metal roof during the time you live in a home. On the other hand, a homeowner with an asphalt roof will likely need to replace it two to three times before moving out if they stay in the home for a 50-year period.
So, while metal roofing may cost more upfront than asphalt roofing, it's a great option for those who are looking to stay in their home for a long time.
- They're Not as Noisy as You Think
If you live in a wet climate, you may be hesitant to install a metal roof because of the excess noise that rain can make when it hits the roof.
However, when a metal roof is installed properly, it's no noisier than any other type of roofing material out there. Typically, metal roofing is installed over a solid substrate that can help absorb some of the noise.
And, your attic and insulation should provide an additional sound barrier.
- Metal Roofing Pairs Well With Solar Panels
If you eventually plan to install solar panels on your roof, then metal roofing can serve as a great base.
While solar panels can work on all different types of roofing materials, metal is an especially good match, as you don't need to drill holes into your roof in order to install the solar panels.
Plus, metal roofs do a great job of supporting the weight of the solar panel system.
- You Have Different Materials to Choose From
Another great aspect of metal roofing is that there is a wide variety of different metals to choose from. Here are some of the most common types of metal roofing worth considering:
- Steel: This roofing material is known for being very heavy and sturdy
- Aluminum: This is a lightweight, soft metal that is very durable, but more prone to damage and denting than steel
- Copper: If properly cared for, copper roofs can last hundreds of years
- Alloy: This type of metal is known for being durable, strong, and tough against weathering
- Stainless-Steel: While very expensive, stainless-steel roofing won't rust or corrode
When deciding on which of these metals is right for you, it's very important to look at your budget as well as the overall look you want for your home or building.
- Metal Roofing Does Have Downsides
With all the benefits that metal roofing offers, it's important to understand that this material still comes with some downsides.
The biggest drawback to metal roofing is the initial cost. Without a doubt, one of the most expensive roofing materials on the market. However, as we mentioned earlier, metal roofs can last for decades and decades, so it is a worthy investment.
The other major downside to metal roofing is that it's prone to denting. If you live in an area that sees hail, then metal roofing may not be your best option.
