When considering a new roof, one of the most important questions homeowners ask is:

“How long does a metal roof last?”

In this article, we’ll explore the expected lifespan of different metal roofing materials, what affects their durability, and how you can make the most of your investment. Whether you're comparing options or planning a re-roof, this guide will help you choose the right solution for your home.

🔹 How Long Does a Metal Roof Last? Breakdown by Material

The answer depends on the type of metal, the quality of installation, and how well the roof is maintained. Below, we’ll cover the most common types of metal roofing used in BC homes.

🔹 Standing Seam: Built to Last 50+ Years

Standing seam metal roofing is one of the most durable and weather-resistant options available. Its vertical seams and concealed fasteners make it ideal for BC’s rainy, windy climate.

Lifespan: 50+ years
Best For: Homeowners looking for a modern aesthetic and long-term durability
Bonus: At Valley Metal Roofing, we manufacture our own standing seam panels in-house using Hylar 5000® coating, designed for superior UV and weather protection.

This style is a top choice for homeowners wondering how long does a metal roof last and seeking peace of mind for decades to come.

🔹 Metal Shingles: Traditional Look, Long-Term Value

Metal shingles replicate the classic look of cedar or asphalt but offer the strength and longevity of steel or aluminum. They’re fire-resistant, pest-resistant, and require little maintenance.

Lifespan: 40–50 years
Best For: Homeowners who prefer a traditional or rustic look
Maintenance: Minimal, just occasional inspections

🔹 Corrugated Panels: Not Recommended for Residential Roofing

Corrugated panels are cost-effective and popular for garages and sheds, but not ideal for residential homes. These panels use exposed fasteners, which are vulnerable to loosening over time due to the natural expansion and contraction of metal.

Lifespan: 30–40 years in ideal conditions
Why Not for Homes? Over time, fasteners may back out, leading to leaks and costly repairs
Best For: Outbuildings or barns — not your home’s main roof

🔹 Copper Roofing: Premium Performance for 100+ Years

Copper is the most luxurious roofing material available. It offers stunning aesthetics, zero maintenance, and exceptional longevity. Over time, it naturally develops a beautiful green patina.

Lifespan: 80–100+ years
Best For: Custom homes or architectural accents
Offered by Valley Metal Roofing: Available on select projects including bay windows, accent roofs, and full re-roofs

🔧 What Affects How Long a Metal Roof Lasts?

If you’re asking yourself “how long does a metal roof last?” — keep in mind that longevity is influenced by more than just the metal type.

Key factors include:

Quality of Installation – Poor installation shortens roof life. We focus on detail-oriented installs backed by a 10-year workmanship warranty.
Protective Coatings – Products like Hylar 5000® help prevent corrosion and color fade.
Ventilation – Proper attic airflow extends your roof’s life and improves home energy efficiency.
Maintenance – While minimal, annual inspections help catch small issues before they become problems.

🏡 Maximize the Lifespan of Your Metal Roof

So, how long does a metal roof last? With the right material, installation, and care, you can expect anywhere from 40 to 100+ years, far outlasting asphalt shingles and delivering long-term value.
