At Mountaintop Roofing Inc., we’ve replaced a lot of roofs over the years. Some were falling apart far too soon, leaving homeowners frustrated with yet another costly repair. Others had held up well but were finally reaching the end of their lifespan. Then there are metal roofs—the ones that outlast just about everything else. If you’ve ever wondered, “How long do metal roofs last?” or if they’re worth the investment, we’re here to give you the real answer.
The truth is, metal roofing isn’t just about longevity; it’s about reliability. Whether you’re battling Calgary’s harsh winters, strong winds, or hailstorms, a metal roof is built to handle it all. But how many years can you really expect from a metal roof? And what factors determine whether yours lasts 40 years or closer to 70? Let’s break it down.
Why Homeowners Choose Metal Roofing
Before we talk about longevity, it’s important to understand why so many homeowners are making the switch to metal.
- Tired of replacing asphalt shingles every 15-20 years
- Looking for a roofing material that stands up to extreme weather
- Want a low-maintenance option that won’t need constant repairs
- Interested in improving energy efficiency and reducing long-term costs
Metal roofs check all these boxes, but their biggest advantage? They last decades longer than traditional roofing materials.
How Long Do Metal Roofs Last Compared to Other Materials?
The Average Lifespan of a Metal Roof
The lifespan of a metal roof depends on the type of metal used, but in general, you can expect:
- Steel roofing: 40-70 years
- Standing-seam metal roofing: 50+ years
- Copper or zinc roofing: 80-100+ years
Compare that to other roofing materials:
- Asphalt shingles: 15-25 years
- Cedar shakes: 30-40 years
- Flat roofing (TPO or EPDM): 20-30 years
Even at the low end of the spectrum, metal roofing outlasts asphalt by at least two to three times. That means fewer replacements, fewer repairs, and greater savings over time.
How Long Do Metal Roofs Last in Calgary’s Climate?
In a city with harsh winters, strong winds, and occasional hailstorms, you need a roof that can handle extreme conditions. Metal roofing is one of the best options for durability, thanks to its:
- High wind resistance: Can withstand gusts up to 140 mph
- Impact resistance: Holds up better against hail than asphalt shingles
- Snow-shedding abilities: Prevents heavy snow buildup and ice dams
- Rust-resistant coatings: Protects against moisture damage
For homeowners in Calgary, a properly installed metal roof can last 50+ years with minimal maintenance—a major advantage in a region where weather takes a toll on traditional roofing.
Factors That Affect the Lifespan of a Metal Roof
1. Type of Metal and Coating
Not all metal roofs are created equal. The material and protective coatings play a huge role in how long they last.
- Galvanized steel: Coated with a layer of zinc for rust protection
- Galvalume steel: A mix of aluminum and zinc, offering even better corrosion resistance
- Painted or powder-coated finishes: Protect against UV damage and enhance durability
2. Quality of Installation
A poorly installed roof—no matter how durable the material—won’t last as long as it should. Proper sealing, fastening, and ventilation are crucial to ensuring longevity.
This is where choosing an experienced roofing company makes all the difference. A professional installation ensures your metal roof is secured correctly, minimizing the risk of leaks or premature wear.
3. Maintenance and Care
One of the best things about metal roofing is that it requires very little maintenance. However, occasional upkeep can extend its lifespan even further.
- Clear debris and leaves from valleys and gutters
- Inspect for scratches or exposed metal and touch up as needed
- Check fasteners and seams periodically
A quick inspection every year can help catch any minor issues before they turn into costly repairs.
Does a Metal Roof Add Value to Your Home?
Aside from longevity, many homeowners ask: Is a metal roof a good investment for resale value?
The answer? Yes. Studies show that homes with metal roofing can see a boost in resale value by up to 5%. Buyers recognize the long-term savings and durability that come with a metal roof, making it a major selling point.
Not only does it last longer than asphalt, but it also offers better energy efficiency. Because metal reflects heat instead of absorbing it, homeowners can see up to 25% savings on cooling costs—another attractive feature for potential buyers.
