One of the decisions that comes with owning a home is choosing what type of roof to install. Whether building a new home or replacing an existing roof, the materials selected can make a difference. Finding the answers to questions like how long does a metal roof last can impact this decision.

There are many other factors that contribute too, such as the location’s climate and weather, how long one expects to own the home, desired aesthetics, and HOA rules. Nonetheless, if willing to consider a metal roof, it’s vital that homeowners are aware of the metal roof’s life expectancy. It’s also not unusual to want to know how long a metal roof lasts compared to traditional roofing materials like asphalt shingles.

How Long Will a Metal Roof Last?

On average and with proper maintenance, a metal roof’s life expectancy will be between 40 and 70 years. But the exact answer to the question, “how long does a metal roof last” will depend on its installation, typical weather elements, and proper maintenance. Installing a standing seam metal roof is the best bet for many homeowners.

Standing seam metal roofs can expand and contract as needed. The result is that the home is heated in the winter and cooled during the summer. This built-in flexibility ensures the metal roof’s panels won’t become warped or worn out from temperature changes.

With a standing seam metal roof, the panels connect and are secure at the seams. This connection method is what allows for the panels’ expansion. However, standing seam metal roofs require paint to cover and protect the steel material underneath.

How Long Does Paint Last on a Metal Roof?

Without paint as a protective coating, a metal roof will rust. In addition, exposure to elements such as rain and snow will cause a metal roof to deteriorate the same way a car’s body will. Typically, paint on a metal roof will last 30 years or more. This all depends on the quality of the paint and the type of warranty offered by the manufacturer or installer.

The paint quality and base will impact the metal roof’s life expectancy. If the color fades quickly and the paint is of low quality that breaks down, the roof’s lifespan will shorten from a lack of protection. In addition, extreme weather events can impact even the highest quality of paints. Think high winds, hail, and heavy snowstorms

How Long Does a Metal Roof Last Under Different Conditions?

So, how long will a metal roof last in different conditions? The factors will depend on the weather, installation, and maintenance. For example, a metal roof’s life expectancy will be longer in an area with calm and steady weather conditions. But a metal roof may not last as long in an area that sees a lot of extreme temperature shifts and storms.

That being said, a metal roof will generally stand up better to harsh weather conditions than a roof made with shingles. So how long does a metal roof last compared to shingles? The answer is that a roof made with shingles lasts between 15 and 30 years. And some shingles are not good about standing up to larger sizes of hail and need replacing within a few months.

However, proper installation and maintenance have just as much influence on a metal roof’s standing power. Professional and proper installation prevents cracks, leaks, and other problems. Regular inspections and upkeep like gutter cleanings can catch minor issues before they become more significant problems.

Metal vs. Asphalt Shingle Roofs

Drive around any neighborhood, and it’s not uncommon to see roofs with shingles rather than metal materials. Some people worry about whether metal roofs will stand up to the cold in northern climates like Minnesota. That’s because many individuals think steel or metal will become too hot or cold during temperature extremes.

While asphalt shingles may not become as hot or cold to the touch, the truth is metal roofs can provide superior insulation. During hot months, metal can absorb and transfer heat much easier than shingles. That means homes will stay cooler in summer and warmer in the winter.

Materials that can handle temperature extremes better is how a metal roof lasts longer than one with asphalt shingles. Homes with shingle roofs usually need a whole house or attic fan to help moderate temperatures. Shingles can also be worn down quicker by the sun’s heat, frost, and freezing temps.

How Can Homeowners Make Metal Roofs Last?

Regular maintenance is the key to how long a metal roof will last. At a minimum, preventative maintenance includes annual inspections and gutter cleanings. Some homeowners have the equipment to clean gutters on their own. If there are a lot of trees near a property, it’s recommended for homeowners to plan on cleaning their gutters twice; once in the spring and again in the fall.

Other homeowners hire contractors to clean their gutters, including flushing out downspouts. Visual roof inspections are something that the homeowner can complete by looking for cracks or obvious defects. However, it pays to have a certified inspector look at the roof yearly, especially around vents and other areas where flashing exists.

If the homeowner suspects any other issues or an inspector notes areas of concern, make the repairs as soon as possible, preventing further problems and damages.
