Asphalt shingles cover the overwhelming majority of residential roofs in the United States. That dominance comes down to cost and availability, not necessarily performance. Metal roofing has grown steadily as a residential option, and the case for it is stronger than many homeowners realize.
Neither material is universally better. The right answer depends on your specific situation.
Head-to-Head Comparison
| Category | Asphalt Shingles | Metal Roofing |
|---|---|---|
| Upfront cost | Lower | Significantly higher (often 2-3x) |
| Lifespan | 20-30 years (architectural grade) | 40-70 years (standing seam steel/aluminum) |
| Wind resistance | Good; varies by shingle rating (110-130 mph typical) | Excellent; interlocking panels rated 140+ mph common |
| Hail resistance | Class 4 impact-resistant available; standard shingles more vulnerable | Generally resistant to denting at typical hail sizes; cosmetic damage possible |
| Weight | Moderate; most structures handle it fine | Lighter than most alternatives including asphalt |
| Noise in rain | Quiet | Audible without proper insulation/decking; manageable with attic buffer |
| Energy efficiency | Standard; cool-roof coatings available | Reflective coatings can reduce cooling load in hot climates |
| Installer availability | Widely available nationwide | Fewer specialists; quality varies more |
| Repairability | Easy; individual shingles replaced | More complex; panel replacement requires matching |
The Lifetime Cost Argument for Metal
Metal roofing's higher upfront cost looks different when you spread it over the roof's life. An architectural asphalt roof may need replacement after 25 years. A steel standing seam roof installed at the same time may still be performing at year 50 -- meaning you'd pay for two asphalt roofs in the time you pay for one metal roof.
The math depends heavily on installation cost in your market, material grade, and how well the roof is maintained. It's a legitimate long-term argument, but it only works if you plan to stay in the home long enough to recover the upfront premium.
When Asphalt Shingles Make More Sense
- You plan to sell within 5-10 years (metal adds value, but you won't recoup the full premium at resale)
- Your budget is constrained and you need a quality roof now at a lower entry point
- You're in a mild climate with infrequent severe storms
- Your current structure isn't suited for the weight distribution differences of some metal systems
When Metal Roofing Makes More Sense
- You're in a high-wind, hurricane, or severe hail zone
- You plan to stay in the home for 20+ years
- Your current roof is reaching end of life and you want to avoid another replacement in 25 years
- You want to maximize energy efficiency in a hot climate with significant cooling costs
- Your homeowner's insurance offers meaningful discounts for impact-resistant or metal roofing
A Note on Metal Roof Types
Not all metal roofs are the same. Metal shingles (stamped to look like asphalt, wood shake, or tile) are a middle-ground option -- lower cost than standing seam, longer lifespan than asphalt. Standing seam (continuous panels from ridge to eave with hidden fasteners) is the premium option, with the best weather resistance and longest warranty terms. Corrugated metal is more common on agricultural structures and lower-cost builds.
Frequently Asked Questions
Does metal roofing attract lightning?
Metal roofing does not increase the likelihood of a lightning strike. Metal is also non-combustible, so if lightning does strike, the roof won't ignite. Many fire-prone regions favor metal for this reason.
Can metal roofing be installed over existing asphalt shingles?
In many cases, yes. Metal is light enough that some installation methods allow it to go over existing shingles without a full tear-off -- which can reduce cost and installation time. A licensed contractor will evaluate the deck condition and local code requirements first.
Is metal roofing loud during rain?
With proper insulation and a solid decking system, most homeowners report that metal roofs are no louder than asphalt inside the home. An open-frame installation without a buffer layer is much noisier.
What does metal roofing look like? Will it look industrial?
Standing seam metal has a clean, contemporary look popular in modern home design. Metal shingles can closely mimic traditional materials. There are styles that work across most architectural contexts, though HOA restrictions sometimes limit options.
Does a metal roof affect home resale value?
A metal roof generally adds to resale value and can be a positive selling point -- especially in markets where storms are frequent. Whether it fully recoups the premium depends on local buyer preferences and how old the roof is at time of sale.
