How Long Do Metal Roofs Last? What Homeowners Should Know

Metal roofs are widely known for being not only strong, but also stylish and long-lasting. If you’re thinking about installing one, you probably have an important question in mind: “how long do metal roofs last?”

Whether you’re in a snowy climate or near the salty air of the coast, metal roofs are built to handle it all. In this guide, we’ll cover everything homeowners should know about metal roofing lifespan, including what impacts it, how it compares to other materials, and how to make it last even longer.

What Is the Average Lifespan of a Metal Roof?

A common question is, “how long do metal roofs last?” On average, a well-installed metal roof lasts between 40 and 70 years.

With proper care, some metal roofs are known to last well over 100 years! However, the exact number depends on the type of metal, the installation quality, and your local environment.

Let’s break it down by metal type:

Aluminum: 40 to 70 years (especially strong near the ocean)
Steel: 40 to 60 years
Zinc: 60 to 100 years
Copper: 80 to over 100 years

Many standing seam metal roofs fall in the range of 50 to 80 years.

How Long Do Metal Roofs Last in California?

Metal roofs in California are known to last approximately 40 to 70 years on average. However, this depends on factors such as the type of metal, installation quality, and maintenance.

Coastal areas may experience slightly shorter lifespans due to saltwater corrosion, but overall, metal roofs are durable and resistant to extreme weather conditions, like heat, rain, and wind.

However, regular maintenance, including cleaning and inspecting for damage, can help extend their lifespan, making them a reliable roofing option in California’s diverse climate.

What Affects the Lifespan of a Metal Roof?

Even the strongest roof won’t last forever, but the lifespan of metal roofs is significant enough.

Here’s what can decide metal roof life expectancy:

1. Type of Metal

Aluminum, steel, and copper each have their own strengths. Steel is tough, but aluminum resists rust better. Copper lasts the longest but costs more.

2. Installation Quality

Poor installation is one of the main reasons metal roofs fail earlier than expected. Seams, fasteners, and flashing need to be done right. SLB offers professional metal roof installation services.

3. Weather Conditions

High winds, salt spray, and snow can wear down roofing over time. Homes near water or in storm-heavy areas need better coatings and fasteners.

4. Maintenance

Metal roofs don’t need much maintenance, but they still need care. Clean gutters, check fasteners, and look for rust or paint damage once or twice a year.

5. Paint Finish and Coatings

Premium paint systems like Valspar or Kynar can extend the life of metal roofing finishes. However, even high-end finishes can start to fade after 20 to 30 years.

Standing Seam Metal Roof Lifespan

A common question among potential homeowners or homeowners looking for a roof replacement is, “how long do standing seam metal roofs last?”

These roofs usually outperform corrugated metal because they have concealed fasteners, which means fewer leak risks.

Typical standing seam lifespan:

With regular maintenance: 50–80 years
With professional installation that involves high-end coatings: Up to 100 years

How Long Do Screws, Fasteners, and Closures Last?

Even if the metal panels stay strong, components like screws and foam closures can wear out faster.

Metal roof screws: 20 to 30 years
Foam closures: 10 to 20 years
Neoprene washers: may dry out after 15–20 years
Paint on screws: often fades faster than the panels

These parts can be replaced during routine inspections, helping you avoid leaks and extend your roof’s life.

How to Make a Metal Roof Last Longer

Now that you have the answer to “how long do metal roofs last,” you will also want to get the most out of your existing or new metal roof.

Here are a few easy ways to increase its lifespan:

Inspect your roof at least twice a year. Also inspect promptly after storms
Keep gutters clear of leaves and debris
Repaint or coat panels every 20–30 years if needed
Replace loose or rusted screws
Avoid walking on panels unless necessary
Hire pros for any major repair or installation

Metal Roof vs Other Roofing Materials

Roof Material	Average Lifespan	Notes
Asphalt Shingles	15–30 years	Cheaper, but needs more replacement
Wood Shakes	20–40 years	Needs lots of care and dries out
Tile Roofs	50–100 years	Durable, but heavy and costly
Metal Roof (steel)	40–60 years	Strong, lightweight, and stylish
Metal Roof (copper)	80–100+ years	Best durability, highest cost

Metal roofing offers one of the best balances between price and lifespan, especially when factoring in lower maintenance and fewer replacements over time.
