I've been roofing in Savannah for over a decade, and nothing has changed the conversations I have with homeowners more than the surge in metal roofing interest over the last three or four years. The combination of rising asphalt shingle costs, increasingly severe hurricane seasons, and insurance companies offering real premium reductions for wind-rated metal roofs has pushed metal into the mainstream in Coastal Georgia in a way it never was before.
This guide covers everything a Savannah homeowner needs to know before making the decision: the types of systems available, what they cost in our market in 2026, which materials hold up best in our specific coastal environment, and what to look for in a contractor. I'll be direct about where metal makes sense and where it doesn't.
Why Metal Roofing Makes Sense in Savannah's Coastal Climate
Savannah's climate is hard on roofing materials in ways that aren't immediately obvious. The combination of factors creates accelerated wear compared to inland markets:
- →Salt air corrosion. Homes within a few miles of tidal marshes, rivers, and the coast receive consistent salt-laden air that degrades standard roofing hardware in years rather than decades. Galvanized fasteners pit and corrode. Asphalt granules wear faster in the salt-humid environment. Metal roofing, when specified correctly for coastal exposure, outlasts these conditions by design.
- →Hurricane wind loads. Chatham County sits in a high-wind zone. The International Building Code requires roofing assemblies to meet 130–140 mph design wind speeds depending on location. Standing seam metal, properly installed with concealed fasteners and continuous clips, is the most wind-resistant roofing system available for residential construction.
- →Algae and biological growth. Savannah's heat and humidity create perfect conditions for Gloeocapsa magma — the algae responsible for black streaking on roofs. Metal is inherently algae-resistant. On asphalt, algae streaks are cosmetic and eventually structural; on metal, they don't establish.
- →Insurance economics. Multiple Coastal Georgia insurers now offer 20–40% premium reductions for homes with Class 4 impact-rated or wind-uplift-certified metal roofs. Over a 50-year metal roof lifespan, the premium savings often exceed the cost premium over asphalt.
Metal Roofing Systems: Which Type Is Right for Your Home?
Not all metal roofing is the same. The three systems we install most commonly in the Savannah market each have distinct trade-offs:
Standing Seam Metal Roofing
Standing seam is the premium system — panels with raised interlocking seams, concealed fasteners, and continuous clip attachment. No exposed screw heads means no entry points for water. The clips float, allowing the panels to expand and contract without loosening over temperature cycles.
| Attribute | Standing Seam |
|---|---|
| Expected lifespan | 50–70 years |
| Wind rating (typical) | 150–180 mph |
| Maintenance | Very low — no fasteners to retighten |
| Cost (Savannah, 2026) | $18,000–$38,000 for typical home |
| Best for | Coastal, waterfront, and high-value homes |
Exposed-Fastener Metal Panels
Exposed-fastener panels (often corrugated or R-panel profiles) attach directly to the deck with screws through the face of the panel. They're significantly less expensive than standing seam and install faster. The trade-off: screws require neoprene washers that degrade after 15–20 years in coastal UV environments, eventually creating leak points. Not recommended for coastal properties within a mile of salt water exposure.
| Attribute | Exposed Fastener |
|---|---|
| Expected lifespan | 30–40 years (coastal: 20–25) |
| Wind rating (typical) | 120–140 mph |
| Maintenance | Fastener inspection every 10 years |
| Cost (Savannah, 2026) | $10,000–$20,000 for typical home |
| Best for | Inland/suburban homes on tighter budgets |
Metal Shingles and Tiles
Metal shingles replicate the look of traditional asphalt shingles, slate, or clay tile using stamped or formed aluminum or steel panels. They install over existing shingles in many cases, reducing tear-off costs. Wind ratings vary by manufacturer; premium systems achieve Class 4 impact resistance. We install metal shingles for homeowners in neighborhoods where a standing seam appearance would look out of place — particularly in Savannah's historic neighborhoods and master-planned communities.
Material Selection: Galvalume Steel vs. Aluminum vs. Painted Systems
The metal substrate matters as much as the panel profile in coastal Savannah:
- →Galvalume steel is the most common substrate — zinc-aluminum-coated steel that resists corrosion well in most environments. One caveat specific to coastal Georgia: Galvalume in direct contact with treated lumber (common in coastal construction) can experience accelerated corrosion from the copper preservatives. Separation or barrier tape is required at all contact points.
- →Aluminum is the premium choice for salt-air environments. It's naturally corrosion-resistant without a coating, which means the protection doesn't degrade over time. Higher material cost (roughly 15–20% more than Galvalume) but the right choice for waterfront and barrier island properties — Tybee Island, Dutch Island, Skidaway Island, and properties along the Intracoastal.
- →Factory-applied paint systems (PVDF/Kynar 500) are what separates a 50-year warranty roof from a 20-year roof. Kynar 500 coatings resist UV fade, chalking, and salt air degradation far better than standard polyester finishes. Any metal roof in Savannah should specify Kynar 500 or equivalent — don't accept polyester-coated panels on a coastal installation.
Metal Roofing Costs in Savannah, GA (2026)
Prices below are based on our 2025–2026 Savannah-area installations. Material costs fluctuate; get current written quotes from at least two licensed contractors.
| System | 1,500 sq ft home | 2,500 sq ft home | 3,500+ sq ft |
|---|---|---|---|
| Standing seam (aluminum) | $16,000–$24,000 | $22,000–$34,000 | $32,000–$50,000+ |
| Standing seam (Galvalume) | $14,000–$20,000 | $18,000–$28,000 | $26,000–$42,000+ |
| Exposed-fastener panel | $8,000–$13,000 | $11,000–$18,000 | $16,000–$26,000 |
| Metal shingles | $12,000–$18,000 | $16,000–$24,000 | $22,000–$36,000 |
Factors that push costs toward the top of these ranges in Savannah:
- Roof complexity: multiple hips, valleys, dormers, or cupolas add 15–30% to installation labor
- Steep pitch (above 8/12): requires additional safety rigging and slows installation
- Deck replacement: many 1970s–90s Savannah homes have OSB or plywood delamination from years of humidity; expect $500–$3,000 in deck repairs
- Aluminum vs. Galvalume premium on coastal/waterfront homes
- HOA or architectural committee requirements (The Landings, Dutch Island) adding submission and approval time
Insurance Benefits: What to Expect in Coastal Georgia
The insurance math on metal roofing has changed significantly in the last two years in Georgia. Several carriers have tightened asphalt shingle coverage or raised premiums for older roofs while simultaneously offering credits for wind-rated metal systems. What we've observed on customer policies:
- →Wind mitigation credits for Class D (130 mph+) or better assemblies: typically 15–35% annual premium reduction
- →Class 4 impact-rated metal systems may qualify for hail resistance credits: additional 10–20%
- →Insurance companies accepting replacement cost value (RCV) on metal roofs vs. actual cash value (ACV) on older asphalt roofs — this changes your payout structure significantly if you ever file a claim
I always recommend requesting a wind mitigation inspection certificate after installation. The inspection costs $100–$150 and the document you get is what your insurer needs to apply the discount. Some customers recover that cost in the first month's premium savings.
Choosing a Metal Roofing Contractor in Savannah
Metal roofing installation is more technically demanding than asphalt shingles. The details matter: clip spacing, seam engagement, trim fabrication, penetration flashing, and thermal movement accommodation all require specific training. Questions to ask any contractor you're considering:
- →Are you a manufacturer-certified installer? Atlas, Drexel, McElroy Metal and others offer certified installer programs. Certification is required to access the manufacturer's 50-year warranty — without it, you may only get the material warranty, not the labor coverage.
- →Do you fabricate panels on-site or order pre-cut? On-site roll-forming means panels are cut to exact lengths — no end laps. For Savannah's long, complex rooflines, on-site fabrication is the right approach.
- →What's your coastal fastener specification? Stainless steel fasteners and aluminum drip edge should be standard on any coastal Savannah installation. If a contractor quotes galvanized hardware, that's a red flag.
- →Will you pull the Chatham County permit? Any full roof replacement or new metal installation requires a county permit. Contractors who offer to skip the permit are exposing you to code violation liability and potentially voiding your insurance coverage.

Frequently Asked Questions
Is metal roofing louder in the rain than asphalt?
Not in practice. Residential metal roofing installs over a solid plywood or OSB deck with underlayment — the deck and attic insulation absorb the sound. Properly installed, metal roofing in rain is no louder than asphalt. The "loud metal roof" experience comes from agricultural or pole barn construction where panels are installed over open purlins without a solid deck.
Will metal roofing attract lightning?
Metal roofing does not attract lightning. Lightning strikes the highest point in an area, regardless of material. Metal roofing is actually safer in a lightning strike because it disperses the charge and won't ignite — it's non-combustible. No Florida or Georgia insurance company adjusts rates for lightning risk based on roof material type.
Can I install metal roofing over my existing asphalt shingles?
In most cases, yes — Chatham County permits allow one roof-over on a structure with a single existing layer. The benefit is eliminating tear-off costs ($1,500–$3,500). The trade-off is that you can't inspect the deck for rot, and you lose roughly 0.5 inches of attic headroom at the eaves. We recommend a roof-over only if the existing shingles are flat and the deck is confirmed sound. If there's any evidence of deck damage, full tear-off is the right call.
How long does metal roof installation take in Savannah?
A typical 2,000–2,500 sq ft Savannah home takes 3–5 days for standing seam installation including tear-off, deck inspection and repair, underlayment, panel fabrication, and installation. Exposed-fastener systems install faster (2–3 days). Complex rooflines, custom trim work, or deck repair add time. We schedule permits in advance so work doesn't stop for inspections.
