How Long Do Metal Roofs Last?

November 18, 2022


Choosing the finest material for roofing a new home or re-roofing an existing one, can be difficult. It can be a concern of aesthetics, budget, or the logical process of determining how long it will survive. Metal roofs continue to be a common roofing material for residential, commercial, and agricultural structures. They are not only long-lasting, but also resilient, stylish, and low-maintenance.

Metal roofs have an excellent lifespan and can survive far longer than other roofing materials. However, many are still skeptical about investing in metal roofs and usually have a lot of questions regarding their lifespan. Hence, as a top-rated metal roofing contractor, we’ll tell you all you need to know about the lifespan of a metal roofing system.

Average Lifespan

The typical lifespan of a metal roof is 40 to 70 years. However, roofs made of copper will survive even longer. Some copper roofs date back more than a century.

At this point, it is important to understand that the lifespan of your metal roof will also depend on other factors. There are several elements that can both increase and decrease the lifetime of your roof.

One of the most significant advantages of metal roofing is its long lifespan, especially when compared to the typical lifespan of asphalt shingles, which is just 15-30 years. Metal panels are engineered to endure environmental stresses, unlike shingles, which may distort and buckle.

Metal has nearly double the average lifespan, and when combined with the durability of modern design, it’s no wonder that more and more people are using it for their new roof or re-roofing alternative.

Factors That Influence The Lifespan Of Metal Roofing

Several factors can influence the longevity of your roofing system. Here are just a few:

Weather Conditions

While metal roofing is incredibly resistant to all forms of weather, it can have an impact on how long the roof lasts. If you live in a relatively warm environment, your roof can last longer than people who live in areas with severe snowfall or high-speed winds.

Even though metal roofs can withstand tough weather incredibly well, elements of weather can still affect them if the metal panels are not chosen according to the weather.

Preventive Maintenance

Another appealing feature of metal roofing is its inexpensive maintenance. They require nearly minimal maintenance after installation. Most of the time, a simple visual examination once or twice a year is sufficient to maintain your roof in good condition.

However, keeping your gutters clean, removing any debris or tree branches from your roof, and doing other preventative maintenance can all help to extend the life of your roofing system.

Appropriate Installation

Proper installation is perhaps the most important and effective way to ensure your roof lasts as long as possible. Metal roofs that are defective or improperly placed are more prone to leaks, cracks, and other issues that can reduce their lifespan.

Hiring a professional contractor to perform appropriate installation will help you get the most out of your roofing system’s lifespan.

Standing Seam Metal Roof

A standing seam metal roof system is made up of panels that are joined together at the seams or mechanically seamed. This permits panels to easily expand and contract as the metal heats and cools.

There’s no reason why your standing seam metal roof shouldn’t last at least 30 years if it’s precisely built and your attic is appropriately vented. A standing seam metal roof may even last for 50 years under perfect conditions.

Screw Down Panel Metal Roof

A screw-down panel metal roof is exactly what it states: it is fastened down with the fasteners visible. Screws and washers drilled through the face of the metal secure the panels. Your screwed-down panel roof might last for 20 years if properly installed and maintained.

However this can be extended to 30 years with proper care. Additionally, because screwed-down metal roof systems screw the metal down, the roof cannot naturally expand and shrink.
