Metal roofing vs. asphalt shingles: which is right for a Georgia home
By Mei Tan · Updated 2026-07-06
Choosing between metal roofing and asphalt shingles is one of the biggest decisions in a roof replacement, and Georgia’s mix of summer heat, humidity, and storms makes the comparison worth taking seriously. Here’s how the two actually stack up.
Upfront cost
Asphalt shingles cost less to install. For a typical 2,000-square-foot single-story roof with tear-off, standard asphalt shingles run about $8,800 to $12,400, and architectural shingles run $11,700 to $16,600. Metal roofing costs more upfront: corrugated steel panels typically run $16,200 to $21,700 for the same size roof, standing seam metal (the more common residential style) runs $22,300 to $29,900, and aluminum panels run higher still.
| Material | Typical cost (2,000 sq ft, tear-off) | Typical lifespan |
|---|---|---|
| Asphalt shingles | $8,800 - $12,400 | 20 - 25 years |
| Architectural shingles | $11,700 - $16,600 | 25 - 30 years |
| Metal, corrugated steel | $16,200 - $21,700 | 40 - 60 years |
| Metal, standing seam | $22,300 - $29,900 | 50 - 70 years |
Lifespan and long-term cost
Asphalt shingles hold up for two to three decades in Georgia’s climate before granule loss and heat cycling wear them down. Metal roofing routinely lasts double that or more, and doesn’t need a full tear-off and replacement anywhere near as often. Spread over 40 or 50 years, the cost-per-year gap between metal and shingles narrows considerably, even though the upfront number looks steep.
Heat and energy performance
Georgia summers push shingle roofs hot, and dark asphalt absorbs a lot of that heat. Metal roofing, especially with a reflective coating, sheds more heat than it absorbs and can measurably reduce attic temperatures. Shingle manufacturers have closed some of that gap with reflective granules, but metal still has the edge in peak summer performance.
Common myths, addressed
Two concerns come up in almost every metal roofing conversation. The first is noise: with solid decking and the underlayment used in a standard residential install, metal roofs don’t sound noticeably different from shingles during rain. The second is lightning: metal doesn’t attract strikes any more than other materials, and its non-combustibility is actually a safety plus if a strike does happen nearby.
A third, more reasonable concern is dent risk from hail, which is real for lower-gauge panels in a severe storm. Heavier-gauge steel and standing seam profiles resist denting far better than thin corrugated panels, so this is a spec question worth asking about directly rather than a reason to rule metal out entirely.
Maintenance and repairs over time
Asphalt shingles are simple to repair: a damaged section can be patched with matching shingles fairly easily, and most roofing crews handle this kind of work routinely. Metal roofing repairs are less common since the material holds up longer, but when they’re needed, they usually require a crew with specific metal roofing experience, since a mismatched panel or a poorly sealed seam can undo the material’s main advantage. Ask any contractor bidding on a metal roof how much of their recent work has actually been metal, not just shingles, since the installation quality matters more for metal’s long-term performance than it does for asphalt.
Insurance and warranty considerations
Some Georgia insurers offer a discount for impact-resistant roofing, and certain metal roofing profiles qualify where standard asphalt shingles don’t, which can offset part of the cost difference over time. Warranty terms also differ: metal panel warranties often run 30 to 50 years, while shingle warranties typically top out around 25 to 30, though both depend heavily on the manufacturer and product tier. Ask your insurance agent directly whether a specific metal roofing product qualifies for a premium discount before assuming it does.
Which one fits your situation
If you’re planning to sell within five to ten years, the lower upfront cost of asphalt shingles is usually the more practical choice. If you’re staying long-term, want lower maintenance, or want better heat performance for cooling costs, metal roofing’s higher price tag can pay for itself over the life of the roof. Either way, get quotes for both from Georgia roofing contractors so you’re comparing real numbers for your specific roof, not just the averages above.

FAQ
- Is metal roofing actually louder in the rain?
- With proper solid decking and underlayment underneath, which is standard installation practice, metal roofing sounds about the same as shingles from inside the house. The noise myth comes from open-frame barn-style installs, not residential roofing.
- Does metal roofing attract lightning?
- No. Metal is not more likely to be struck by lightning than any other roofing material, and it doesn't increase the risk to the home. If anything, metal is non-combustible, which is a safety advantage in a strike.
- Is metal roofing worth the higher upfront cost?
- It depends on how long you plan to stay in the home. Metal typically lasts 40 to 70 years against 20 to 25 for asphalt shingles, so the cost per year of roof life often favors metal for long-term owners.
- Can you install metal roofing over existing shingles?
- Sometimes, but tearing off the old roof first is usually the better call, since it lets the installer check the decking and gives the new roof a clean, flat base.
