Here’s the truth: Metal roofing isn’t just a trend — it’s one of the most durable, long-lasting investments you can make for your home.
In fact, when properly installed and maintained, metal roofs can last 40 to 70 years — sometimes even longer. Compare that to the 20 or so years you’ll get from asphalt shingles, and it’s no wonder more Rehoboth Beach homeowners are asking us at Grand Exteriors: Is a metal roof the right move for my home?
If you’re thinking about upgrading, you probably have questions like: Will a metal roof really survive the salt air and storms we get here on the coast? Is the higher upfront cost worth it in the long run? What should I expect in terms of maintenance and upkeep?
Good news — we’re here to walk you through it. In this post, we’ll break down how long metal roofs last, why they perform so well in coastal climates, and how Grand Exteriors helps Rehoboth Beach homeowners make the most of this smart, long-term investment.
What Makes Metal Roofs Last So Long?
Built for Strength and Resilience
When people ask how long do metal roofs last, they’re often surprised to hear that, with the right material and installation, these roofs can easily last 40–70 years. Premium metals like copper or zinc can even stretch that lifespan to 100+ years.
So, what’s behind their long life? It comes down to a few key factors: durable materials that resist cracking, shrinking, and eroding; protective coatings that help prevent rust, corrosion, and UV damage; and expert installation, which ensures everything is properly fastened, flashed, and sealed. At Grand Exteriors, we know from experience that a metal roof’s lifespan isn’t just about the material — it’s also about the craftsmanship behind the installation.
Metal Roofs vs. Other Roofing Materials
How They Stack Up
Here’s a quick comparison of typical roof lifespans: asphalt shingles (20–30 years, often less in coastal environments), wood shakes (20–40 years with regular maintenance), clay or concrete tiles (40–50 years), and metal roofing (40–70 years, sometimes longer). If you’re looking for one of the longest-lasting roofing options — especially for a Rehoboth Beach home — metal consistently comes out near the top.
Why Metal Roofs Excel in Rehoboth Beach
Designed for Coastal Living
Salt air, high winds, and heavy rains can wear down many types of roofs over time. But high-quality metal roofing systems, especially aluminum or coated steel, are specifically designed to handle these harsh coastal conditions. At Grand Exteriors, we help homeowners choose metal products that are corrosion-resistant and engineered for high-wind areas — ensuring you’re not just buying durability, but the right kind of durability for where you live.
What Impacts the Lifespan of a Metal Roof?
1. Material Choice
Aluminum, steel, zinc, and copper all offer excellent longevity, but they perform slightly differently under coastal conditions. For example, aluminum resists salt corrosion better than steel, while copper offers unmatched longevity but at a higher cost.
2. Installation Quality
No matter how good the product, poor installation can cut a roof’s lifespan short. Our Grand Exteriors team ensures every detail — from underlayment to fasteners to flashing — is handled with precision.
3. Maintenance and Care
Metal roofs are low-maintenance, but not no-maintenance. Occasional cleaning, debris removal, and inspections help catch small issues before they turn into big ones, extending the life of your roof.
Benefits Beyond Longevity
More Than Just a Long-Lasting Roof
While a metal roof’s long life is impressive, there are other important benefits that add value: energy efficiency, as metal roofs reflect sunlight and help keep your home cooler, lowering energy bills; sustainability, since many metal roofs are made from recycled materials and are fully recyclable at the end of their life; and curb appeal, as metal comes in a variety of colors, styles, and finishes, giving your home a sleek, modern look or a traditional charm, depending on your style.
