Replacing a roof is a significant investment, so investing in a roof that lasts for years to come is essential. As homeowners seek to maximize their roofs' lifespan, it is no surprise that residential metal roofing has been steadily increasing in popularity.
What is the Life Expectancy of a Metal Roof?
Metal roofs can last for fifty years or more, outpacing a shingle roof's lifespan by decades. This impressive durability means that for many homeowners, a metal roof will be the last roof they purchase.
Metal roofs are also resistant to shrinking, eroding, and cracking making them able to withstand extreme weather conditions like heavy snow and hail storms. This durability means that metal roofing requires infrequent maintenance or replacement. Typically, a quick yearly inspection for minor maintenance is all that’s needed to keep a metal roof in working order.
How Does the Life Span of a Metal Roof Compare to Shingles?
Asphalt shingles are one of the most commonly used roofing materials because they are available at lower prices. However, those lower upfront costs are often outweighed by a limited lifespan and frequent maintenance. Asphalt shingles present several challenges; they are susceptible to water damage, mold and rot, pests, fire hazards, and high wind damage. In addition, shingles don't offer the energy efficiency that owners expect, and regular maintenance can be rigorous depending on your region and the surrounding elements

Expert Insights On Metal vs Shingles
The Metal Roofing Alliance puts the lifespan of asphalt shingles at 10-20 years before requiring a replacement. Additionally, asphalt roofing needs frequent repairs, shingle replacement, and re-caulking and sealing as the roof ages.
Experts in the field agree. McElroy Metal recently interviewed John Wilusz of Advanced Metal Roofing, and his stance on the wisdom of this investment was apparent. He shared, "If we're playing the long game, metal is the clear winner." He passionately pointed out the longevity factor, saying, "You're not just buying a roof; you're making a one-time investment for the next half-century."

What Makes Metal Roofs Last?
So you know their reputation - metal roofs stand the test of time and can even outlive your mortgage. But what makes them last? While the metal panels themselves are durable, the entire metal roofing system is comprised of cohesive parts, with each component designed to resist the elements. Metal roofs can withstand weather conditions that many other materials cannot. High winds, hail, snow - metal is built to weather the storms Mother Nature throws your way without worries of shrinking, eroding, or cracking.
The Class 4 roof rating process confirms this information. This impact test is used to measure resistance to hail and debris and carries a prestigious standard of performance and safety. McElroy Metal is proud to offer over two dozen profiles in steel with a Class 4 rating. Properly installed metal roofs are also resistant to condensation, mildew, and rot, which are common pitfalls with asphalt shingles. They're also fire-resistant, giving you peace of mind.
All of these benefits add up to deliver a product that lasts 2-3 times longer than a shingle roof. That’s why metal roofs often represent the lowest-cost roofing option. Read this analysis to learn more.
Consider The Whole Picture
When planning your roofing project with longevity in mind, consider the whole picture. Correct materials and proper installation are fundamental to building a roof that lasts for the maximum length of time.
It is essential for owners to choose the substrate and coating for their metal panels that match long-term performance expectations. For residential applications, that means we recommend a Galvalume® substrate paired with Kynar® paint to resist fade and chalk and keep the roofs you install looking like new for decades!
