Asphalt shingles often make sense when initial cost and straightforward replacement matter most. A well-designed metal roof can offer long service life and a distinctive appearance, but its higher price pays off only if the system suits your home, climate and plans.
There is no universal winner. “Metal” includes several substrates and fastening systems, while asphalt shingles range from basic products to premium architectural designs. Compare actual specifications and installers, not just the material names.
The main tradeoffs
| Question | Asphalt shingles | Metal roofing |
|---|---|---|
| Initial cost | Usually lower; premium products cost more. | Usually higher, especially standing seam and specialty metals. |
| Service life | Depends on product, installation, ventilation and weather. | Can deliver several decades; corrosion, detailing and maintenance matter. |
| Maintenance | Inspect for displaced or damaged shingles, flashing problems and debris. | Inspect seams, flashings, coatings and fasteners appropriate to the system. |
| Appearance | Familiar dimensional texture; many colors and profiles. | Standing seam offers strong vertical lines; other metal products mimic shingles, shake or tile. |
| Installer selection | Widely available, but quality still varies. | Find demonstrated experience with the exact panel and detailing system. |
Look beyond the initial price
A higher metal-roof price can be reasonable if you expect to keep the home long enough to benefit from its service life. It is less persuasive if you would stretch your budget to obtain benefits you may never use. Repairs, financing costs, expected ownership period and future replacement all belong in the comparison.
For a dated planning reference, Western States Metal Roofing’s January 11, 2026 steel pricing guide lists installed standing seam at $10–$16 per square foot and corrugated metal at $7–$12. It notes additional cost for removing an old roof. Local scope and market conditions can produce different results. Manufacturer price guide. See How Much Does a New Roof Cost? for area, allowances and hidden conditions.
Service life is not the same as a warranty
NRCA’s homeowner resources describe most new roof systems as designed for about 20 years of useful service and identify metal among systems that can last longer, with actual life influenced by the assembly, climate, installation and maintenance. Avoid treating a single lifespan number as a guarantee. NRCA homeowner resources.
A “lifetime” shingle warranty is a defined contract term, not a promise that every part of the roof will last your lifetime without maintenance. Equally, a long metal paint warranty does not automatically cover leaks. GAF’s warranty comparison illustrates why product and workmanship coverage need separate review.
Not all metal roofs are the same
Standing seam versus exposed fasteners
Standing seam uses raised seams and concealed attachment, often with clips that accommodate movement. Snap-lock and mechanically seamed panels are different systems with different slope and installation requirements. Concealed fastening reduces exposed penetrations through the panel field; it does not eliminate the need for careful flashing and maintenance.
Exposed-fastener roofing has visible screws through the panels, commonly with sealing washers. It usually costs less, but those fasteners and seals become inspection and maintenance points. Ask how they will be monitored and serviced. Do not assume that a lower-cost exposed-fastener bid is equivalent to standing seam. Manufacturer comparison of the two systems.
Steel, aluminum and copper
- Steel: common and relatively economical among metal choices. The protective metallic coating, paint, cut edges and environmental suitability deserve attention.
- Aluminum: light and often selected for coastal exposure. It does not develop steel’s red rust, but it can corrode and may be more susceptible to visible denting. Thickness and engineering matter.
- Copper: a premium material with a naturally changing patina. It needs compatible details and careful separation from metals that can be harmed by copper contact or runoff.
Ask for the substrate and thickness in writing. A thickness number for steel is not interchangeable with the same number for aluminum. Sheffield Metals explains substrate differences and material compatibility.
Compare the tested roof assembly
Fire and wind
Metal is noncombustible, but the fire classification of a roof depends on the tested assembly, including what is underneath. Asphalt-shingle systems can also achieve Class A external fire ratings; for example, Owens Corning lists that classification for its Duration shingles. A roof covering’s rating does not establish that an entire house is wildfire-proof. Duration product specifications.
For wind, compare the specified product approval and installation for the site: deck attachment, panel clips or shingle fastening, edge details and design pressures. A product’s advertised wind figure or limited warranty is not a substitute for the required project design. Ask the contractor how the proposed assembly addresses local wind exposure.
Energy performance
Do not assume every metal roof is “cool” or every shingle roof is hot. Solar reflectance, thermal emittance, color, climate, insulation and the complete assembly affect the result. Reflective versions of both materials are available. ENERGY STAR notes that cool roofs tend to save more energy in hot, sunny climates and less-insulated buildings. ENERGY STAR cool-roof guidance.
Compare the actual product’s rated properties and local energy requirements rather than relying on a promised utility-bill percentage. Ask whether the selected color—not just the product family—has the necessary listing.
Coastal homes: substrate and coating both matter
Salt exposure can change the material decision. Aluminum is frequently preferred in severe coastal conditions because of its corrosion behavior. Sheffield Metals discusses this advantage, while also noting denting and thermal-movement considerations. Aluminum roofing advantages and drawbacks. Some purpose-designed coated-steel products also have coastal applications; suitability must be confirmed for the actual exposure and warranty.
PVDF coatings, including formulations using Kynar 500® resin, are valued for resistance to weathering, fading and chalking. That is not the same as making every substrate immune to corrosion. Arkema explains Kynar 500 weatherability.
Before buying, get written answers about distance-from-saltwater limitations, paint and substrate warranties, cut-edge treatment, fastener and flashing compatibility, and any required washing or maintenance. “Kynar finish” alone does not answer those questions.
Which material fits your project?
Asphalt may fit better when you want a lower initial expense, a familiar neighborhood appearance and access to a broad pool of installers. Choose a specific product and insist on complete accessory, flashing and ventilation details.
Metal may fit better when you value its appearance and potential service life, can fund the complete installation comfortably, and have an installer experienced with the selected system. Allow for movement, penetrations, maintenance and the site’s environment.
Architecture also matters: view full-size samples or completed nearby roofs before deciding. Ask about seam spacing, flat pans versus intermediate ribs or striations, gloss and visible waviness (“oil canning”). On a prominent roof, these choices affect the result as much as the color name.
A useful decision test: Request a complete shingle option and a complete metal option for the same measured roof. Compare total installed scope, written warranty coverage and maintenance responsibilities. Then ask what the higher-priced option adds that you personally value.
