How Long Does Metal Roofing Last?
Depending on the material, metal roofs can last 40 to 70 years. The lifespan of conventional asphalt roofing materials is thought to be between 12 and 20 years.
Metal roofing is a top option for owners of homes and businesses due to its advantages and longevity. Energy-efficient, fireproof, and low-maintenance are all benefits of a metal roof.
Factors Affecting the Lifespan of Metal Roofing
The lifetime of your roofing system might vary depending on a few distinct factors, however it typically lasts between 40 and 70 years. Here are a few examples:
Weather can affect how long a roof lasts, even though metal roofing is incredibly resilient to all kinds of weather. For instance, if you reside in a region with moderate weather, as opposed to one with severe rain, snowfall, or high-velocity winds, your roof may last longer. Even though metal can incur natural wear and tear from harsh conditions, it will withstand those extreme elements and wind much better than other materials. Making sure you have the correct panel to handle the environment and regular weather conditions in your location requires careful consideration of the metal panel you choose.
The low maintenance required by metal roofing panels is another incredibly alluring benefit. They practically require no maintenance after installation. On the other side, cleaning asphalt shingles may be necessary to get rid of roof algae that eventually causes ugly black streaks.
The majority of the time, a straightforward visual homeowners’ inspection once or twice a year is sufficient to keep your roof in great condition. However, performing other kinds of preventative maintenance, such as checking that your gutters are clear, removing any debris or tree limbs from your roof, will help your roofing system last longer.
The best and most reliable technique to make sure your roof lasts as long as possible is to install the roofing materials properly. Metal roofs that are defective or improperly placed are more vulnerable to leaks, cracks, and other problems that can reduce their lifespan. You may extend the life of your roofing system by making sure to either hire a qualified contractor or ensure appropriate DIY installation.

Why Does Metal Roofing Last So Long?
A big benefit of a metal roof is its longevity, which is no coincidence. Metal possesses a number of qualities that contribute to its outstanding lifespan, including the following:
The main factor contributing to metal roofing’ long lifespan is how strong and durable they are. This toughness is essential to a roof’s lifespan. You can count on your metal roof to remain weatherproof in even the worst conditions due to its excellent wind-uplift, heavy-rainfall, ice and heavy-snowfall, and impact resistant ratings. They are genuinely long-lasting and built to last. Additionally, in coastal and hurricane-prone areas, its wind resistance is a benefit and increases the curb appeal and value of your property.
Metal panels, in contrast to other materials, genuinely keep pests away from your house. Pests may be drawn to wood shakes and shingles, but not to metal roofing. This prolongs the lifespan of your roof and enables it to function as it should.
Despite popular opinion, metal roofs are not just sheets of metal; they are a comprehensive and integrated system made up of robust, high-performing components. In order for you to get the most out of your roof, roofing systems are more sophisticated than ever, and their clip systems, fasteners, and other accessories have been built using the newest technology.
Overall, metal roofing is a fantastic option for people who want to put a roof and then not have to worry about it for decades. Aside from its endurance, metal roofing has several other advantages, including fire resistance, light weight, impact resistance, and wind resistance.

What is the lifespan of a standing seam metal roof?
A standing seam metal roof system consists of several panels that are mechanically or mechanically-locked together at the joints. As a result, when the metal heats up and cools down, the panels can expand and contract freely.
Standing seam metal panels are painted with a finish called Kynar 500 using a patented method that is used by all of the main steel panel producers. Your metal panels are shielded from the weather by this coated finish, which also protects the color of your choice from fading.
A 30-year paint warranty is included with your standing seam metal roof for the Kynar 500 finish. The 30-year warranty on the paint does not guarantee that it will no longer exist in 30 years.
Your standing seam metal roof should last for at least 30 years if it is done correctly and your attic is properly aired. A standing seam metal roof might last 50 years under ideal circumstances.
How long does a metal roof with screw-down panels last?
A metal roof with exposed fasteners that is screwed down is exactly what it is termed; the bolts are visible. Screws and washers are used to secure the panels, and they are inserted through the metal’s surface.
The Kynar 500 painted finish does not come with screw-down panels. The type of warranty you receive on a screw down metal roof system will depend on the type of paint that is applied to the steel or aluminum panels.
Your screw down panel roof might last 20 years if installed correctly and maintained without any problems. You might extend it to 30 years with routine maintenance.
Be warned that because screw down metal roof systems screw the metal down, the roof cannot naturally expand and shrink. Professionals do not advise installing a screw down metal roof over a hot place, such as your home or business, due to this lack of expansion flexibility.
How to Get the Most Life Out of Your Metal Roofing
You should unquestionably maintain your metal roof if you want to get the most use and value out of it. Any rust should be removed right away, and the area should be fixed.
The location of the roof has a significant impact on how long it might last. If you live close or on a beach, depending on the weather, your metal roof might only last 10 years if it is not well maintained and the improper finish is chosen.
Three factors shorten the life of your metal roofing.
Now that you are aware of the two types of metal roofs’ lifespans. But do you know what shortens or lengthens their lives?
The lifespan of your metal roof depends on local weather conditions and measures taken to preserve the metal panels’ finish. Learn more about the three main elements that determine how long your metal roof will last by reading on.
- During installation, was the painted finish on the metal roof panels shielded?
The panels of your metal roof system are stylishly painted, which safeguards the metal. Kynar 500 is used in standing seam metal panels whereas the manufacturer’s chosen paint finish is used in screw down panels.
The fresh steel in the panels will rust if the coating is scratched or damaged, exposing the metal to dew or moisture in the air. The finish must be protected throughout installation, so it is essential that your local roofing contractor take all necessary steps.
For instance, the roof must be cleaned each evening once the workday is finished. Because the steel will rust over night, they cannot leave cuts, tiny triangles, or any other form of shavings on the roof.
No matter what type of metal roofing system you have, it’s critical that it be installed with care. Because of this, making the investment in a metal roof, finding a great local roofing contractor is essential.
- To what types of weather would your metal roof be subjected?
Every roof experiences weather-related wear and tear throughout the course of its lifetime. How quickly that wear and tear affects your metal roof depends on the frequency of extreme weather in your location.
The integrity and finish of your metal roof panels can deteriorate more quickly if you reside in a region that experiences a lot of snow, ice, and hail. The more it has to expand and contract, the shorter its lifespan will be if you have a screw-down metal roof and live in a region where temperatures are frequently high.
You have no control over the weather. Just be aware that the weather in your area will affect how long your metal roof lasts.
- Does your metal roof receive yearly maintenance?
No matter what kind of roof you have, it’s crucial to get an annual maintenance inspection even if it was put in properly.
The only maintenance necessary once a standing seam roof is constructed is at the penetrations, which include vent pipes, gas pipes, etc. Despite the fact that it requires little maintenance, you should still have it checked once a year to safeguard your money and keep it leak-proof.
Because the fasteners on a screw down panel are exposed, they require more care than those on a standing seam. The strain brought on by the metal’s lack of expansion and contraction over time will eventually lead the screws to wallow out the washers’ holes.
Without upkeep, this causes leaks and reduces the longevity of the screw-down metal roof.
Copper Roof Lifespan
A copper roof that is old will turn green. As a copper roof gets older, a protective covering that has a greenish hue is formed and is known as patina.
Despite being the most expensive roofing option, a copper roof is frequently regarded as the greatest roofing system overall. It is the best in terms of aesthetics, toughness, and environmental friendliness. To prevent decay in copper, you don’t have to rely on paint treatments. Additionally, individuals can utilize it for smaller dwellings due to its lightweight nature.
What is the lifespan of a copper-made metal roof? It should last for at least 50 years, if not more. maximum 100 years. The patina that forms on copper roofing over time shows corrosion. However, this blue-green layer is protective in that it further waterproofs your roof.

Lifespan of Tin Roofing
You might have never heard of a tin roofing system before. The industry does not use it very frequently. Tin existed before people thought of aluminum as the standard for metal roofing.
If the sound of rain on your tin roof worries you, you can reduce the noise by adding roof underlayment materials.
Life Expectancy of Steel Roofing
Systems for steel roofing are adaptable. You can always purchase a steel roof that mimics slate, shingles, or clay if you choose.
Did you realize that some steel roofs from the turn of the century still exist? Steel roofs are so durable in this regard. In fact, as compared to asphalt shingles, steel roofs can last considerably longer between significant repairs. They are a wise long-term investment, as you can see.
Manufacturers cover the roofing seals to prevent rust. Some homeowners believe that the design of metal roofing causes difficulties. The good news is that there are many metal roofing options available that mimic different styles of roofs.
Lifespan of Aluminum Roofing
With an average lifespan of 50 years, aluminum is recognized as the most lightweight metal roofing material. Steel is not the best aluminum if you reside near the coast. Steel is more susceptible to corrosion, but aluminum resists it. Elastomeric coatings must be used to waterproof aluminum roofing.
The energy-efficiency of this metal roof is another advantage. It is made to keep your house cool throughout the warmer months and minimize your utility bills. The sun’s heat and light are reflected by the aluminum metal roof. Due to its weight, an aluminum roof shouldn’t require much time to install.
Lifetime Expected for Zinc Roofing
As you can see, copper isn’t actually the most durable roofing material. A zinc roof has a lifespan that is comparable. However, a clean atmosphere is necessary for a long life. A zinc roof resists corrosion. On top of an existing roof, contractors can add zinc roofing.
A zinc roof (architectural grade) is 90–95 percent recyclable, making it a sustainable material. The ability of a zinc roof to mend itself is, however, what makes it so extraordinary. You don’t have to worry about leaking or hiring a roofing professional if it gets scratches.
