Whether your current roofing is falling apart or you're just looking to make a change and better protect your home, you may be considering a metal roof. One of the most common questions about this material is how long does a metal roof last.

The good news is that a metal roof life expectancy is far longer than other roofing materials. In fact, a metal roof has an even longer life expectancy than most humans. A properly installed metal roof that is well-maintained can last up to 125 years.

But there are more benefits and factors to consider than just the average lifespan when deciding if this material is right for you. Learn all about how long metal roofs last and what you can expect from your new roof.


Why Choose a Metal Roof

While asphalt has long been the traditional go-to choice for houses, so many homeowners are now looking at other options for their homes. Different materials, from asphalt to clay tiles, bring pros and cons of their own.

So let's take a look at why metal roofing pros recommend this material to homeowners so you can decide if these advantages are what you're looking for.


A metal roof's life expectancy is much longer than other materials such as an asphalt shingle roof. Even conservative estimates claim 50 years, but proper maintenance may allow a lifespan of over 100 years.

One reason they last so long is that they are highly durable. Even in extreme weather, homeowners can rely on their strong shingles.

Resistant to Common Roofing Dangers

Whatever dangers you imagine for roofs, it's often safe to assume that metal roofs are resistant.

For example, a heavy weather impact like hail could end clay tiles, but metal is far more durable. As for fire, these roofs are resistant to it. And for those who have dealt with pesky bugs like termites in the past, worry no longer — these roofs have nothing to offer these pests.

Are you blasting your air conditioner all summer long with little relief? Perhaps your roof isn't doing its fair share in keeping your home comfortable.

One of the ways metal roofing is so environmentally-friendly is that it's energy-efficient. This means it lowers your winter heating costs and summer cooling costs. You save money and the environment by using less energy to make your home's air livable.

Here's how its energy efficiency works:

• The aluminum reflects the sun in summer, resulting in a 50% reduction in heat transfer from the sun compared to an asphalt shingle roof.

• Improved ventilation means hot air escapes properly, and the air conditioner can work more efficiently than when under asphalt shingles.

In addition to being energy-efficient, metal roofing is made from recycled materials, which can then be recycled again. And because it lasts so long, you'll replace your shingles less, reducing your carbon footprint and decreasing the demand for supplies.


Caring for Your Metal Roof

All roofing materials require some level of maintenance and care, including metal. But what is needed for a metal roof? Here's what you should know.

If there has been severe damage to your home that poses a risk to you, contractors will inform you of whether repairs will do the trick or if it's time to consider installing replacement shingles.

If you need to save money now, asphalt shingles may be best. But for those looking for the wisest investment, metal roofs are the right choice.
