How Long Do Metal Roofs Last

If planning to install a new roof or replace the current roofing structure on your property with a metal roof, you might have questions about this option. One of these questions is, how long do metal roofs last? Ideally, you want to know how long your investment will last.

Well, you most likely know that durability is the primary benefit of metal roofs. Typically, a metal roof comes with a warranty of 40 years. And this is longer than that of a traditional roof. Some metal roofs last longer than 60 years. Compared to 23 years for asphalt shingles and 20 years for single-ply roofs, metal roofs are arguably the most durable.

At GT Roofing, we focus on providing the best roofing solutions to our clients. Regardless of your roofing needs, we have the expertise, technology, and experience to cater to them. Be confident you will get the best metal roofing once you choose our service. But to help you make an informed decision, learn more about the longevity of metal roofs.

How Long Do Standing Seam Metal Roofs Last?

Standing seam metal roofing comprises panels locked together or seamed mechanically. The seams allow the metal panels to contract and expand freely due to cold and heat. The roof manufacturers utilize patented processes in applying paint finish to the metal panels of this roofing. And this creates a painted finish that protects the metal panels from environmental elements while preventing fading of their color.

Most standing seam metal roofs have a warranty of 30 years. However, most standing seam metal roofs outlive their contract.

How Long Do Screw Down Panel Metal Roofs Last?

These roofs come with exposed fasteners or screw-down panels. The manufacturers of these roofs fasten the panels using screws, after which they screw washers through the metal faces. Most of these roofs come with a painted finish, and the warranty depends on whether the manufacturer used aluminum or steel panels.

Nevertheless, these metal roofs can last more than 20 years with proper installation. You can stretch the longevity of your screw-down panel roof to 30 years with regular maintenance. The inability of this roof to expand and contract affects its durability.

Factors Affecting Their Lifespan

Several factors can affect the lifespan of a metal roof. At GT Roofing, we want you to get the most from your metal roofing. As such, we want you to have all the necessary information about taking care of your metal roof from the moment you hire us to install it. Here are factors likely to affect the longevity of your metal roofing.


How well you install your metal roof will influence its longevity. If you want to install a metal roof with a painted finish, protect it during the installation process. That’s because the painted finish protects the material that the manufacturer used to make the roof, which is the metal in this case. Damaging or scratching the panels exposes the metal to the air, moisture, or due. And this can cause rusting. To avoid this, hire competent experts to install your metal roof.

GT Roofing has highly trained and experienced metal roofing contractors ready to install your metal roof professionally. When installing your metal roofing, we will take precautions to ensure the optimal protection of your panels’ finish.

Regardless of the metal roofing you choose, we will handle it carefully to avoid damaging it during installation. That way, your metal roofing can last long after installation.

Weather Conditions

The weather conditions in your area will affect the longevity of your metal roofing. Weather causes tears and wears on your roof. If your neighborhood has extreme weather, your metal roofing will tear and wear faster. If the place where you live gets a lot of hail and snow, the finish and integrity of your metal roof panels are likely to weaken quicker.

If your area receives high temperatures regularly and installs a screw-down metal roof, the lifespan of your roofing system will be shorter due to its limited expansion capability. Ideally, you can’t do anything about the local weather. Therefore, consider it a factor when deciding on the metal roof type to install on your property.


Even after hiring us to install your metal roof professionally, make sure that experts maintain and inspect it regularly. After installing a standing seam roof, you don’t perform any maintenance practices. However, you should schedule annual inspections to ensure that your investment is in proper condition.

Screw-down panels in a metal roofing expose it to damage by weather elements. Therefore, you should maintain your screw-down panel roofing regularly. The holes in the screw-down panels can wallow out because of the screws and lack of contraction and expansion. And this necessitates regular maintenance for this roof type. Without regular maintenance, a screw-down metal roof will develop leaks.

To extend your metal roof’s longevity, clean debris and dirt more often. Also, inspect fasteners for possible corrosion and ensure the flashing is in proper shape. If you notice scratches on your metal roofing, hire experts to repaint it.
