how long does corrugated metal roof last?

Corrugated metal roofs are a popular choice for both home and business owners because of their durability, strength, and long lifespan, as well as their ability to withstand extreme weather conditions. And not just that, it is also relatively low maintenance and can be recycled at the end of its lifespan.

If we talk about how long does corrugated metal roofing lasts? Well on average, it can last anywhere between 20 to 50 years or more.

However, the actual lifespan of a corrugated metal roof will depend on a number of factors, including the quality of the materials used, the climate in which the roof is installed, and the level of maintenance it receives.

In this article, we will learn more about what factors affect its lifespan and what can be done for prolonging it. This will definitely help you decide whether to go with this type of roofing or not.

What Will Affect the Lifespan of Corrugated Metal Roofing?

There are several factors that can affect the lifespan of corrugated metal roofing:

  1. Quality of the material: The quality of the metal used for the roofing will determine its lifespan. If the metal is of low quality, it may be prone to corrosion and may not last as long as high-quality metal. Galvanized steel, which is coated with a layer of zinc, is a popular choice for corrugated metal roofs because it is resistant to corrosion and can last for up to 50 years or more. Aluminum and copper are also commonly used for corrugated metal roofs, and these materials can have even longer lifespans of up to 70 years or more.
  2. Installation: Proper installation is crucial for the longevity of the roof. If the roof is installed incorrectly, it may not be able to withstand extreme weather conditions and may need to be replaced sooner than expected.
  3. Maintenance: Regular maintenance is necessary to extend the lifespan of a corrugated metal roof. This includes cleaning the roof regularly to remove dirt, debris, and rust, as well as repairing any damage as soon as it is discovered.
  4. Climate: Climate also plays a role in the lifespan of a corrugated metal roof. In areas with extreme weather conditions, such as high winds, heavy rain, or intense heat, a corrugated metal roof may not last as long as it would in more moderate climates. Proper installation and maintenance, such as regularly cleaning and inspecting the roof, can help to extend its lifespan in these conditions.
  5. Exposure to the elements: The roof’s exposure to the elements, such as UV radiation, wind, and hail, can also affect its lifespan. A roof that is exposed to these elements more frequently will likely need to be replaced sooner than a roof that is protected from them.

Tips for Prolonging the Service Life of Corrugated Metal Roofing

  1. Keep the roof clean and free of debris: Regularly inspect and remove any debris, such as leaves, branches, or other materials that may accumulate on the roof. This can help prevent water damage and leaks.
  2. Repair any damage promptly: If you notice any dents, holes, or other damage to your corrugated metal roof, have it repaired as soon as possible. Delaying repairs can lead to further damage and costly repairs.
  3. Use a high-quality sealant: Applying a high-quality sealant to your corrugated metal roof can help protect it from water damage and extend its lifespan. Make sure to reapply the sealant every few years to ensure it remains effective.
  4. Trim trees and branches near the roof: Overhanging trees and branches can damage your roof by scraping against it or falling onto it during storms. Trimming these back can help prevent damage to your roof.
  5. Install a roof ventilation system: Proper ventilation can help reduce heat buildup on your roof, which can lead to premature wear and tear. Installing a roof ventilation system can help prolong the lifespan of your corrugated metal roof.

What Is the Average Lifespan of Different Types of Corrugated Metal Roofs?

Here are some estimates for the average lifespan of different types of corrugated metal roofs:

  • Galvanized steel: 20-25 years
  • Galvalume: 25-30 years
  • Aluminum: 30-50 years
  • Copper: 50+ years

It’s worth noting that these are just estimates, and the actual lifespan of a corrugated metal roof can be shorter or longer depending on the specific conditions it’s subjected to. Proper maintenance and upkeep can also help extend the lifespan of a corrugated metal roof.

Overall, corrugated metal roofs are a long-lasting and durable option for any type of property and with proper installation, maintenance, and use of high-quality materials, a corrugated metal roof can easily last for 50 years or more, providing reliable protection for your home.
