How Long Do Metal Roofs Last (And Why)?

Exact Answer: 40 to 100 years

When purchasing a new roof, homeowners should evaluate several factors, including aesthetic, efficiency, expense, investment return, and, most significantly, life span. The roof of your home might mean the difference between a plain dwelling that provides shelter and a safe and secure house.

Over the years, metal roofs have grown in popularity. There are various advantages to placing a metal roof on your home, in addition to its extended life expectancy. Metal roofs are available in several shapes and colors, whether in sheet or tile form. The aesthetically beautiful metal roof is composed of 100 percent recycled components and, when removed, is 100 percent recyclable, making it significantly more environmentally beneficial than traditional roofing materials.

A metal roof has a substantially longer lifespan than other types of roofs. Properly fitted metal roofs can last 100 years or more, depending on the type of metal roof material you choose and how well you maintain it. Certain metals have a greater life expectancy than others.

Metal roofing panels are not only less expensive, but they are also superior temperature regulators, which means you will save money on your energy expenses. Throughout the lifespan of your metal roof, your home will be more protected against natural and unnatural forces such as insects, rats, winds, rainfall, hailstorm, fire, and other nasty elements.

Metal roofs are more difficult to install, so only a professional roofing firm with metal roof installation experience should be engaged. Metal roofs can also be put over your existing roof, resulting in less labor and debris when removing your old roof.

A metal roof’s life expectancy can be affected by several factors, including:

  • Perfect Installation – This is perhaps the most important and effective approach to ensure that your roof lasts as long as possible. Metal roofs that are faulty or improperly installed are more prone to leaks, cracks, and other issues that can reduce their lifespan.
  • Low maintenance – Another appealing feature of metal roofing panels is they are low maintenance. They require almost no maintenance after installation. Most of the time, a simple visual inspection once or twice a year is all that is required to keep your roof in a good condition.
  • Weather – While metal roofing is incredibly resistant to all forms of weather, it can have an impact on how long a roof lasts. If you live in a warm climate, your roof may survive longer than people who live in areas with severe snowfall or high winds. Choosing the proper metal panel is critical in ensuring that you obtain the right panel for your area’s environment and usual weather conditions.

Why Does Metal Roof Lasts For So Long?

The lifetime of a metal roof is a huge benefit, and this is not by chance. Metal has several qualities that contribute to its outstanding lifespan, including the following:

  • Durability – The fact that metal roofs are robust and resilient is the primary reason they survive so long. This durability is critical to a roof’s lifespan. With outstanding wind-uplift, heavy-rainfall, heavy-snowfall, and impact resistance ratings, you can rely on your metal roof to operate in even the most extreme conditions. They are constructed and made to last.
  • Metal panels stop pests from entering your home, unlike other materials. Wood shingles and shakes can attract bugs, but metal roofing does not. This extends the life of your roof and allows it to perform as it should.
  • Robust Components – Metal roofs are a comprehensive system made up of tough, high-performing components, not just sheets of metal. Roofing systems are more modern than ever before, and their clip systems, fasteners, and other accessories have been built with cutting-edge technology to ensure that you get the most out of your roof.

Some weather conditions, depending on the type of metal you chose, can reduce the life expectancy of your metal roof. Metal will rust in any weather condition that produces moisture, such as rain, snow, sleet, or humidity. Certain types of metal roofs are more vulnerable to hail damage than others. Sunlight and heat can also cause corrosion and shorten the lifespan of your metal roof.

Conclusion

Metal roofs are still a very popular roofing material for household, industrial, and farming structures. Metal roofing is an excellent choice for people who want to install a roof and not have to worry about it for decades. There are numerous other advantages of metal roofing, but one of the most significant is its lifespan.

A metal roof can last between 40 and 125 years, compared to 12 to 20 years for standard asphalt roofing. They are environmentally friendly since you can recycle 100 percent of the roof when it needs to be replaced.
