How Long Does a Steel Roof Last?

It’s well-known that metal roofing is more resilient than other roofing options like asphalt or wood. While the average asphalt roof lasts about 20 years, metal roofs can last between 50 and 200 years. The lifespan of your metal roof comes down to the type of material you choose and how you maintain it. Different materials have different life spans. So, you need to choose a material for your metal roof that fits your budget and the amount of time you want to invest in its maintenance. 

Steel roofing is the most common metal roofing material, and it is often just called “metal roofing” because of its frequent use. Because of its popularity in metal roofing, we are frequently asked “how long does a steel roof last” and “how often do metal roofs need to be replaced.” For steel roofing, its longevity depends on its maintenance and your choice of coating materials; knowing both can save you time and money.

 

How Long Does a Steel Roof Last Compared to an Asphalt Roof? 

On average, steel roofs last 50 years before replacement is needed, and they are up to 35% recyclable. In comparison, asphalt roofs last for around 20 years. The longer lifespan of steel roofs helps bring more long-term value to your building than non-metal roofing materials. Buildings with metal roofing typically have a higher resale value than buildings that do not. While the initial installation cost of a metal roof may be higher than an asphalt roof, metal roofs last 3-6 times as long as an asphalt roof. This saves you money in the long run. 

 

Steel Roof Durability

Steel roofs are highly durable and do not easily corrode, crack, or damage on impact. In fact, State Farm found metal roofs can endure winds up to 140 mph if they are installed correctly. Unlike asphalt roofs, metal roofs do not rot or have mildew problems, nor are they susceptible to termite damage. Also, steel roofing is one of the few fire-resistant roofing materials available, so it is a great option for buildings in areas prone to wildfires. 

 

How Long Does a Steel Roof Last with Maintenance?

Proper metal roof maintenance can increase how long your steel roof lasts. Fortunately, it doesn’t take a hefty amount of time to do so. Steel roofs don’t need periodic maintenance the way asphalt roofing does. Because of their durability, metal roofs need less maintenance than asphalt roofing. In the end, you invest less time maintaining a metal roof than an asphalt one.

 

Steel Metal Roof Maintenance Tips:

  • Recoat

After long-term exposure to the elements, the protective coating on your steel roof will deteriorate. You’ll need to recoat your roof every five to ten years to ensure its longevity. A simple polymer coating restores your metal roof and keeps it protected for the next decade or so. 

  • Wash

Dirt stuck to your roof can damage the paint and your home’s appearance, so wash your roof regularly, especially after storms. Use a simple soap and water mixture with a hose or pressure washer to remove dirt from your metal roof. Avoid using abrasive tools like steel wool or wire brushes or else you could scratch the paint off your roof.

  • Remove Debris

Snow, branches, and leaves can clog your gutters and damage the roof’s framing if they stay on your roof for too long. Make sure to clean out your gutters for blockages and use gentle snow removal tools to remove heavy snowfall from your roof. 

  • Inspect after Storms

Checking your roof right after a storm can stop a bad problem before it starts. Severe weather like strong winds, hailstorms, and heavy snow can damage your roof and cause issues if not attended to immediately. After extreme weather, inspect your roof for any loose trim, damaged flashing, wobbly fasteners, or dented panels.
