Choosing between metal roofing and asphalt shingles comes down to a few factors that are specific to you: your budget, how long you plan to stay in the home, what your roof looks like structurally, and how much importance you place on long-term value versus upfront cost.
Both are solid options. Both work well in Western North Carolina’s climate. But they are not the same product, and they do not suit the same situation equally. This comparison walks through the honest trade-offs so you can make a clear-headed decision.
Lifespan: Where Metal Has a Clear Advantage
This is probably the most significant difference between the two materials.
Standard three-tab asphalt shingles typically last 20 to 25 years. Architectural shingles, including premium lines like GAF’s Timberline® HDZ and Timberline® UHDZ™, can reach 30 years or more with proper maintenance. That is a good run for a residential roof.
Standing seam metal roofing averages 50 to 60 years. Installed correctly and maintained properly, some metal roofs outlast the people who put them on. If you are in a home you intend to stay in long-term, the math on metal gets interesting quickly.
Upfront Cost: Asphalt Wins Here
There is no getting around it. Metal roofing costs considerably more upfront than asphalt shingles. The materials are more expensive, and the installation requires more specialized skill and time.
For a standard residential home in the Asheville area, the cost difference between an asphalt shingle replacement and a standing seam metal installation can be significant. If budget is the primary consideration right now, asphalt shingles are the more accessible option.
However, this is where the long-term calculation matters. If asphalt requires replacement in 25 years and metal lasts 55, you are potentially paying for two asphalt roofs in the same period you would pay for one metal roof. Factor in the labor costs for each replacement, and the financial picture over a 50-year period often favors metal.
Weather Performance in Western NC
Western North Carolina gets real weather. Hail storms, heavy rain, high winds, ice accumulation in higher elevations, and the occasional severe event all put roofing materials through their paces.
Metal roofing handles these conditions well. Standing seam panels with concealed fasteners are rated for wind speeds up to 140 mph and are significantly more resistant to hail impact than asphalt shingles. They do not crack, curl, or shed granules. In snow and ice conditions, metal surfaces shed accumulation more readily than textured asphalt.
Asphalt shingles are not fragile by any means. Quality architectural shingles handle standard WNC weather without trouble. They are more vulnerable to severe hail and have a shorter effective lifespan under prolonged UV exposure, but they are a proven product that has been protecting homes in this region for decades.
For properties at higher elevations, in exposed ridge-top locations, or in areas that see frequent severe weather, metal offers a meaningful performance advantage.
Energy Efficiency
Metal roofing panels with infrared-reflective finishes reflect solar radiation rather than absorbing it, which keeps the surface temperature lower than traditional asphalt shingles. In the warmer months, this translates to a cooler attic and reduced demand on your home’s air conditioning.
Asphalt shingles absorb more heat, which can contribute to higher summer cooling costs depending on your attic’s ventilation setup. This gap is most noticeable in homes where the attic space is directly conditioned or where ventilation is limited.
For homes in lower-elevation areas of WNC and into the upstate South Carolina markets we serve, the energy efficiency benefit of metal may be more relevant than it would be at higher elevations where summer heat is less of a factor.
Appearance Options
A common misconception is that metal roofing means an industrial or utilitarian look. That has not been true for a long time.
Modern metal roofing comes in standing seam panels, exposed fastener panels, and look-alike products designed to mimic cedar shake, slate, and other traditional materials. Color options are broad. If you want a distinctive, architecturally interesting roof that lasts a lifetime, metal gives you that without sacrificing the home’s curb appeal.
Asphalt shingles also offer significant aesthetic variety. GAF’s Timberline® HDZ line alone comes in over 20 color options, with a wood-shake look and a dimensional depth that photographs well and holds up visually over time. The Virtual Remodeler tool on GAF’s website is a practical way to see how different colors will look on your specific home.
Noise: Addressing a Common Concern
One question that comes up often: does metal roofing sound loud when it rains?
With proper installation, including appropriate underlayment and insulated panels, metal roofing is not noticeably louder than asphalt. The loud drumming sound associated with older metal roofs applies mostly to uninsulated metal barns and utility buildings. A residential metal roof installed over proper decking and underlayment performs comparably to other materials in terms of interior noise.
Which Is Better for the WNC Climate Specifically?
Both work. The choice depends more on your priorities than on some absolute superiority of one material over the other.
If you want the longest possible product lifespan, the strongest resistance to severe weather, and a premium appearance that adds to your home’s resale value, metal is worth the upfront investment. If you want a well-proven material at a more accessible price point, with a strong warranty backing from a manufacturer like GAF, architectural asphalt shingles are a sensible choice that millions of homeowners have relied on for decades.
When a Hybrid Approach Makes Sense
Some homes benefit from a mixed approach. Using metal for the most exposed, high-pitch sections and asphalt for lower-slope areas, outbuildings, or additions can balance cost and performance in specific situations. This is worth discussing with your contractor if your roof has varied sections with different exposure profiles.
Frequently Asked Questions
Can metal roofing be installed over existing asphalt shingles?
In some cases, yes. A re-cover installation places metal panels over an existing layer of shingles, which can reduce labor cost and eliminate disposal fees. This only works if the decking is solid and the existing material is in acceptable condition. A full tear-off is generally preferred because it allows inspection of the decking and typically produces a better long-term result.
Will metal roofing increase my homeowner’s insurance cost?
Metal roofing can actually reduce your insurance premium in some cases, or make you eligible for discounts, due to its fire resistance and durability in severe weather. Check with your insurance provider about potential adjustments.
How do I know if my home’s structure can support metal roofing?
Metal roofing is lighter than most homeowners expect. Standing seam steel panels weigh roughly 1 to 1.5 pounds per square foot, which is comparable to or lighter than asphalt shingles. Most residential framing handles metal without any structural modification. Your contractor can confirm this during the inspection.
Is there a big difference in maintenance requirements between the two?
Both require periodic inspection and maintenance, though metal requires less frequent attention. Asphalt shingles benefit from regular inspection for granule loss, cracking, and flashing integrity, particularly after severe weather seasons. Metal roofing should be checked periodically for fastener condition and to make sure panel seams remain sealed, but it is generally a lower-maintenance product over its lifespan.
Does metal roofing affect Wi-Fi or cell signal?
No. This is a persistent myth. Metal roofing does not meaningfully interfere with wireless signals or cell reception inside the home.
