What Factors Determine How Long a Metal Roof Lasts?
Just like with anything else, the lifespan of your metal roof will depend on several factors. One of the biggest driving factors is the kind of materials that are being used.
Metal Roof Materials
Steel roofs, especially those that are coated with zinc (galvanized), or those that are a mixture of aluminum and zinc (galvalume), are known for being strong and resistant to corrosion. These kinds of metal roofs will typically last homeowners anywhere from 40 years to 50 years.
Another type of metal roof material is aluminum. Aluminum metal roofs are lightweight and highly resistant to rust. This kind of material is usually used in more coastal areas that are prone to rust damage. Aluminum roofs can last anywhere up to 50 years and if properly maintained, they will last even longer.
Copper metal roofs are another type of metal roof material. If you are seeking to get the most durable metal roof, copper would be the best choice for you as it is known to be one of the most durable options. Copper metal roofs will usually last over 70 years.

Climate
The climate in which your home is located can impact how long your metal roof lasts. Luckily, metal roofs are designed to withstand a variety of weather conditions; however, it is also important to note that some climates will affect your metal roof differently than others.
For cold climates, metal roofs are excellent at shedding snow and ice, which prevents buildup that leads to leaks and strucural damage. The downside to cold climates and metal roofs is that if your metal roof is not installed properly, extremely cold weather can sometimes cause contraction and expansion issues. That is just something that you need to keep in mind if you are located in the more cold climates.
On the other hand, for hot climates, metal roofs reflect sunlight. which helps to keep your home cooler and ultimately reducing your overall energy costs. However, prolonged exposure to intense heat can cause the metal to expand, which is why proper installation and ventilation are extremely essential for the longevity of your metal roof.
In coastal climates, your metal roof will face salty air. This is important to note because salty air can accelerate corrosion in certain metals. Choosing corrosion-resistant materials, such as aluminum or appropriated coated steel, can help to prevent this issue.
Maintenance
If you take care of your metal roof, it will take care of you! Regular maintenance is the key to maximizing the lifespan of your metal roof. While metal roofs are generally low-maintenance compared to their counterparts, a few routine tasks will help keep them in top condition.

You should always keep your roof clean as well. You can do this by removing debris, leaves, and dirt regularly, but especially after a storm. Acccumulated debris can retain moisture, leading to rust and corrosion over time.
If you believe that your metal roof will need some kind of minor repair, you should promptly address this minor repair. Minor repairs consist of fixing small leaks or replacing loose fasteners. If these minor issues are neglected, they will lead to significant damage and reduce how long your metal roof lasts.
