Metal roofs are becoming increasingly popular in the United States. In 2019, only 12% of US homes had metal roofs. In 2021, the percentage of residential homes with metal roofing went up to 17%.
If you are considering a metal roof for your home, you probably have a lot of questions. One of the most common ones we get at Murray Roofing is: how long does a metal roof last?
A metal roof can last an average of 50 years, depending on a number of factors. One of the main factors is the type of metal roofing system you choose for your home.
In this guide, we want to help you understand why some metal roofs last longer than others. We also explain additional factors you may want to consider before choosing the system that is right for you.
Types of Metal Roofing Systems
The two most common types of residential metal roofs are standing seam and screw-down panel metal roofs. Screw-down panel roofs are the most basic and affordable while standing seam metal roofs are more modern and durable.
We will talk more about the advantages and disadvantages of these types of roofing systems in a moment. But first, we want to explain a bit more about the structure of screw-down panel vs standing seam metal roofs.
Standing Seam Metal Roofs
Standing seam metal roofs are highly durable options for residential homes. They consist of panels of metal that interlock with one another. Roofing contracts fasten them to roof decks with clamps or other kinds of fasteners.
The benefit of the interlocking system these roofs use is that the individual panels have space to expand and contract with changing temperatures. All the while, they still maintain their tight, waterproof seal.
Another reason many homeowners choose this type of roofing system is its aesthetics. Standing seam metal roofs offer more curb appeal. The fasteners are hidden beneath the metal panels with no exposed nails needed.
Screw-Down Panel Metal Roofs
Screw-down panel metal roofs are less durable because of the way they attach to roof decks. They feature aluminum or corrugated steel panels, each of which comes with a screw that fastens the roof to the deck.
Even though this type of roofing system is more affordable, most homeowners do not choose it for their homes. Instead, screw-down panel metal roofs are more popular for barns, sheds, and carports.
Why? These roofing systems do not look as seamless or appealing as standing seam metal roofs. The exposed screws make for a seal that is not as tight, either, which makes for more frequent metal roof repairs.
How Long Does a Metal Roof Last?
A metal roof will last anywhere from 20 to 75 years. The exact metal roof lifespan depends on multiple factors. That includes the type of metal roofing system and the material used.
For example, steel and aluminum tend to last 40–50 years. Meanwhile, metal roofs that consist of copper or zinc panels can last up to 100 years when cared for correctly.

How Long Do Screw-Down Panel Metal Roofs Last?
Screw-down panel metal roofs can last up to 30 years under the right conditions. However, it is more common for these roofs to need replacement after only 20 years.
Additionally, you have to get screw-down panel metal roof maintenance every five to 10 years. Specifically, the screws have to be replaced regularly. Without regular maintenance, this type of metal roof may not even last 20 years.
How Long Do Standing Seam Metal Roofs Last?
Standing seam metal roofs can last 50–75 years with no issues. At the very least, this type of metal roof should last 30 years. It is more common for them to last at least twice as long as that without the need for metal roof repairs.
Unlike screw-down panel roofs, standing seam metal roofing systems need little to no maintenance when installed properly. They rarely leak and provide superior protection from storms and high winds.
How Much Does a Metal Roof Cost?
A metal roof's cost depends on the type of system used but can range from $4.50–$15 per square foot. The exact cost depends on multiple factors, including whether you want screw-down panels or standing seams.
How Much Do Screw-Down Panel Metal Roofs Cost?
Screw-down panel metal roofs cost around $4.50 per square foot. You must also pay for roofing services and screw replacement every five years to keep your roof in tip-top shape.
How Much Do Standing Seam Metal Roofs Cost?
Standing seam metal roofs made of 24-gauge steel cost around $12–$15 per square foot. A thinner gauge or less expensive type of metal will lower the cost per square foot.
What Is the Best Type of Metal Roof?
The best type of metal roof depends on your budget and aesthetic preferences. As we've mentioned, standing seam metal roofs are the more attractive option since they do not have exposed screws.
Standing seam metal roofs cost more than screw-down panel metal roofs. However, they last twice as long and require less metal roof maintenance. That means this type of roofing system will save you more money over time.
