Metal roofs have become a popular option for all types of buildings. They’re known for their incredible durability and longevity, making them a good choice for areas with extreme weather conditions, like Arizona.
However, a new roof is a big investment. A metal roofing system costs more per square foot than other roofing options, so you’ll want to ensure it’s worth the money.

How Long Does a Metal Roof Last?
The lifespan of metal roofs varies depending on several factors, but on average, a metal roof will last 30-50 years. Some standing seam metal roofs have lasted up to 70 or 100 years.
The longevity of your metal roof will be determined by:
- The weather: Arizona is known for extreme heat and heavy monsoons. These conditions can age your metal roof more quickly, so it doesn’t last as long.
- The type: There are two types of metal roofs. Standing seam metal roofs require less maintenance to last longer, while traditional exposed fastener metal roofing may need more attention over the years.
- The thickness: Metal roofing panels are between 22 and 28 gauge in thickness. Thicker panels can withstand the elements better but also weigh down your roof.
The average asphalt shingle roof has a life expectancy of 15-20 years. Though the Arizona climate can be harsher on roofs, you should still be able to get at least 30 years out of a metal roof system. This makes metal roofs one of the area’s most preferred roofing systems. With regular upkeep and painting, you could extend the life of your metal roof as much as two to three more decades.
The Benefits of Metal Roofing
An impressive lifespan is just one of the benefits of metal roofing. Metal roof panels are highly durable. They’re designed to provide incredible resistance against common roof concerns like wind uplift, heavy rain, and impact damage.
Traditional roofs create an inviting environment for wildlife and pests to make their home in your shingles. The colder properties of metal roofs deter pests from burrowing into your roof.
A metal roofing system is made of components that are built to last. Standing seam panels are held in place by interior clips, meaning there are fewer entry points for water to seep in and cause damage.
Though screw-down metal panels provide more opportunities for moisture build-up, their modular nature means damaged pieces are easy to replace.
Even the paint on a metal roof offers extra longevity. The paint finish protects the metal panels and comes with a long-term warranty. Sometimes, a new coat of paint is enough to extend the life of a metal roof.
What Makes a Metal Roof Last?
Metal roofing materials should last for decades with little maintenance. However, there are some things you can do to ensure your roof doesn’t need to be replaced anytime soon:
- Have your roof inspected after a big storm to check for damage to any of the panels.
- Refinish your roof with a fresh coat of paint and ensure there are no scratches in the finish. Damage to the finish allows water to mingle with the metal panels, causing rust.
- In areas with high heat, like Arizona, opt for a standing seam roof over a screw-down roof. Screw-down metal roofs are unable to expand and contract as easily.
- Minimize points of entry for water to avoid leaks. Common vulnerabilities include skylights, chimneys, and seams.
- Get regular inspections on your roof to maximize its lifespan. For a metal roof, maintenance will be minimal, but it may be necessary around penetration points like roof vents.
