Residential + Commercial · Coastal Georgia
Coastal Roofing of Georgia installs metal roofing in Savannah, GA on houses, warehouses, churches, retail centers, and historic-district buildings. Savannah metal roofing comes down to two honest choices. Standing seam hides its clips under the rib so nothing ever punctures the panel face, and it runs 40 to 50 years. Exposed-fastener panels like R-panel and screw-down corrugated cost less to put on and give you 20 to 30 years before the gaskets and screws start asking for attention. Almost everything we install on the coast is 24-gauge aluminum-zinc coated steel with a PVDF finish, because salt air punishes anything thinner or cheaper.
This page is the whole picture: what a metal roof in Savannah actually costs, which panel profile belongs on your building, why the coast changes the spec, how the install runs week by week, and what the warranty really covers.

Pricing
Metal is the most expensive roof you can buy per square foot and the cheapest one you can own per year. That trade is the whole conversation. Below is what we actually quote around Savannah, priced per square foot of finished roof, tear-off and trim included.
| Metal roof system | Installed cost per sq ft | Service life | Typical use |
|---|---|---|---|
| Residential standing seam | $12.00 to $22.00 | 40 to 50 years | Houses, coastal builds, historic homes |
| Commercial standing seam (24-ga) | $11.00 to $18.00 | 40 to 50 years | Churches, schools, retail, offices |
| R-panel / PBR (exposed fastener) | $7.00 to $11.00 | 25 to 30 years | Warehouses, metal buildings, ag |
| Screw-down corrugated | $5.00 to $8.00 | 20 to 25 years | Barns, outbuildings, budget structures |
| Metal shingle and interlocking profiles | Quoted per project | 30 to 50 years | Homes wanting a traditional look |
A 2,400 square foot roof on a Savannah or Pooler house, done in residential standing seam, comes out around $28,800 to $52,800. A 20,000 square foot commercial standing seam roof runs $215,000 to $345,000. The same 20,000 square feet in R-panel is $140,000 to $220,000, and in screw-down corrugated it is $100,000 to $160,000.

Panel types
Every metal roof falls into one of two families. Either the fasteners are hidden under the seam, or they go through the face of the panel. That single difference sets the price, the lifespan, and how the roof eventually fails.
Vertical legs lock together over a concealed clip. No screw ever touches the weather surface. We install 1 inch, 1-1/2 inch, and 2 inch rib heights in both snap-lock and mechanically seamed versions, chosen by slope and exposure. Snap-lock is fine on steeper residential pitches. Mechanically seamed is what belongs on low-slope commercial work and on anything sitting out in open wind. Standing seam works down to 1:12 on commercial buildings and is the profile we put on most Savannah projects.
Exposed-fastener panels built for warehouses, metal buildings, and agricultural structures where cost outweighs looks. They go on fast and cover a lot of ground per man-hour. The catch is the neoprene washer under every screw head. Those gaskets age out long before the steel does, and coastal humidity accelerates it. Plan on a re-fastening and re-gasketing pass every 10 to 15 years to keep an R-panel roof honest.
The cheapest metal roof there is. Fasteners go through the high ribs into purlins or deck. It has a real place on barns, sheds, pole buildings, and structures where 20 to 25 years is the honest expectation. We install it when that is genuinely the right answer and we say so when it is not.
Stamped metal in slate, shake, and diamond profiles for owners who want a traditional roof line with metal underneath it. Mostly a residential and small-commercial choice. Interlocking edges give good uplift performance and the panels ship in manageable pieces, which matters on tight downtown lots where a 40 foot panel simply cannot be maneuvered.
Specialty metals for historic restorations and landmark buildings inside Savannah's review district. Expensive, long-lived, and appropriate on very few roofs. When a building calls for it, nothing else will pass review.
The spec sheet
Our standard standing seam build, written manufacturer-neutral. Panel gauge, clip spacing, and seam height get adjusted per project based on wind exposure, slope, and historic district requirements.
| Component | Standard spec | Coastal Georgia note |
|---|---|---|
| Panel material | 24-gauge aluminum-zinc coated steel | The aluminum-zinc coating handles salt air far better than plain galvanized |
| Paint finish | PVDF (Kynar 500-class) fluoropolymer | 40+ year color fastness, UV-stable through Coastal Georgia summers |
| Seam height | 1-1/2 inch raised standing seam | Mechanically locked rib to rib over concealed clips |
| Clip attachment | Concealed clip fastened to the substrate | Lets panels expand and contract without fastener fatigue |
| Clip spacing | Per panel manufacturer wind-zone tables | We spec to the coastal zone, not the inland default |
| Fasteners | Coated or stainless, matched to the panel metal | Mismatched metals corrode galvanically in salt air |
| Underlayment | Self-adhering high-temp synthetic | Lasts the life of the metal above it, unlike asphalt felt |
| Substrate | Half-inch plywood, over polyiso on commercial decks | Hard plane for the clips, stops foot-traffic deflection |
| Edge details | Pre-formed eave trim, rake trim, ridge cap | Closure strips at every termination keep wind-driven rain out |
| Service life | 40 to 50 years to first major intervention | The longest-lived roof we install, residential or commercial |
The coastal variable
A metal roof spec that works in Macon does not automatically work in Savannah. Chloride in the air accelerates corrosion on every exposed metal edge, and the closer you are to the marsh, the Wilmington River, or the Atlantic, the faster it moves. Six things change on a coastal job.
Color and coating
Color is not just a taste decision here. It drives your cooling bill, the surface temperature of the deck below, and the length of the finish warranty you get in writing.
PVDF, the Kynar 500 class of finishes, is the standard we spec. It carries a 30 to 40 year fade and chalk warranty from the panel manufacturer and meets Cool Roof Rating Council reflectance criteria in the lighter colors. It is the same fluoropolymer chemistry used on aerospace coatings: UV-stable, chalk-resistant, and still holding its color when a cheaper paint has gone flat.
SMP, silicone-modified polyester, is the budget finish. It typically carries a 25 year warranty and fades noticeably in 12 to 15 years in Coastal Georgia sun. It is fine on a barn or an outbuilding. It is not what belongs on a roof you intend to keep for 40 years.
The most reflective colors we install around Savannah are mill-finish aluminum-zinc, regal white, solar white, sandstone, and slate gray. Dark bronze, hunter green, and matte black look sharp and absorb a lot of heat. On a steep residential roof with good attic ventilation that is a manageable trade. On a low-slope commercial deck it is not the choice we would make.

Two different jobs
People use the phrase metal roof as if it means one product. On a house and on a warehouse it means two fairly different assemblies.
| Residential metal | Commercial metal | |
|---|---|---|
| Panel gauge | Commonly 26-gauge, 24-gauge on the coast | 24-gauge standard |
| Panel width | 12 to 18 inches | 16 to 24 inches |
| Typical slope | 4:12 and steeper | 1:12 to 4:12 |
| Seam method | Snap-lock is common | Mechanically seamed on low slope |
| Substrate | Plywood or OSB deck | Purlins, or plywood over polyiso insulation |
| What drives the decision | Curb appeal, storm resistance, never re-roofing again | Cost per year of ownership, downtime, energy load |
Warehouses in the port corridor go 24-gauge aluminum-zinc standing seam, snap-lock profile, with continuous insulation underneath. R-panel is the honest budget alternative when the owner's horizon is shorter. Retail and office buildings take PVDF-finished standing seam matched to the brand palette. Schools and churches get mechanically seamed 24-gauge, because the highest wind rating and the lowest maintenance bill both matter to those owners. Inside the historic district, copper, zinc, or terne-coated stainless on the buildings that call for it, with the Certificate of Appropriateness handled as part of the project.
Coastal and marsh-front houses that keep losing shingles to wind. Homes in Richmond Hill, Pooler, and Rincon where the owner intends to stay put and never wants another re-roof. Older homes downtown where a standing seam roof is period-correct and review-board approved. And houses with steep, simple gable lines, where metal is at its cheapest and its best.
The process
Metal is a fabricated roof, not a stocked one. Panels get made to your building's dimensions, which means the calendar looks different from a shingle job. Expect roughly 6 to 10 weeks from signature to final walk, with the crew on your roof for a much shorter stretch of that.
Crew time on the roof itself is usually 3 to 7 days on a house and 1 to 3 weeks on a commercial building, depending on size and complexity. We schedule commercial work around your operating hours where we can.

Why the seam matters
Standing seam and screw-down metal are mechanically different animals. The difference is how the panel is held down, and that is the entire reason metal roofs leak or do not.
Lifespan and warranty
A standing seam roof installed correctly in Coastal Georgia gets 40 to 50 years before it needs a major intervention. R-panel gets 25 to 30. Screw-down corrugated gets 20 to 25. Those numbers assume the panel substrate suits the environment and the fasteners were not an afterthought. They fall apart quickly when either is wrong.
Three separate warranties come with a metal roof, and owners routinely confuse them.
From the coil coater. Covers fade and chalk on the paint. PVDF typically runs 30 to 40 years. SMP typically runs 25. It does not cover leaks.
From the panel manufacturer. Covers rupture, perforation, and structural failure of the metal itself. Coastal proximity clauses are real, so read the exclusions.
From us. Covers the installation: flashing, seams, terminations, fastening. The term is written into your contract before you sign it.
On commercial projects, panel manufacturers also offer extended weathertightness warranties that require specific details, inspections during construction, and registration paperwork. We handle those submissions when the project calls for one.
The thing to watch on any coastal metal roof warranty is the distance-to-saltwater exclusion. Most panel finish warranties reduce coverage inside a set distance from breaking surf or standing saltwater. If your building sits on the marsh, that clause matters more than the headline number, and we will point it out before you sign rather than after a claim gets denied.
Repair and retrofit
Metal roofs do not fail evenly. They fail at specific, predictable points, and after enough of them you can almost call the diagnosis from the driveway. Around Savannah it is the same short list: pipe boots that dried out and split, fastener back-out on older screw-down panels, sealant gone brittle at the ridge, seam separation from panels that were never allowed to move, and corrosion working through gutters and drip edge where salt collects.
We diagnose those individually instead of quoting a blanket panel replacement. A well-maintained 30 year old standing seam roof will often run another 20 years on targeted repair work. A screw-down roof past 15 years is usually telling you something different, and more patching is not the answer.
When an exposed-fastener roof is at the end of its run, a retrofit usually beats a tear-off. We frame a sub-purlin system over the existing panels and install new standing seam on top of it. No landfill bill, no exposed deck, no shutting the building down, and the new roof carries the same 40 to 50 year expectation as any other standing seam install. On commercial buildings we can add insulation in the cavity while we are at it.
Allowed in most jurisdictions when total layer count and dead load stay inside the structure's capacity. It saves tear-off cost. It also hides whatever the deck is doing underneath, so we core-check and confirm code before recommending it. Metal directly over single-ply membrane is a different story and generally not something we will sign off on.
When metal wins
Metal costs substantially more up front than single-ply membrane, roughly $11 to $18 per square foot against $5.50 to $11. The math only works when one of four things is true about your building.
If you plan to own the building for decades and never want to think about the roof again, metal pays for itself by skipping one or two membrane replacements along the way. Single-ply needs replacing every 20 to 25 years. Metal does not.
A church sanctuary, a downtown historic building, an upscale hotel. White single-ply membrane is not the right answer on any of them. Standing seam is. Most of the church and historic-district metal work in greater Savannah looks like this.
Single-ply belongs on low slope, under 2:12. Above that, metal is both the structural and the aesthetic answer. Pitched commercial buildings with gables, hipped pavilions, and dormers go metal nearly every time.
Some owners want the best roof on the market regardless of payback math. Metal is that roof. We are not going to talk anybody out of it. We install it right and document it for the next 50 years.
Still weighing the two? Flat roof vs metal roof in Savannah lays the systems side by side.
Where we work
Our shop is in Richmond Hill, which puts every one of these towns inside a short drive. Salt exposure changes noticeably across that map, and so does the spec we write. For metal roof installation in Garden City, start at roofing in Garden City, GA; for the west side of the county, see roofing in Bloomingdale, GA.
Historic district standing seam under review board approval, downtown commercial buildings, midtown and southside homes, and warehouses along the port corridor.
Newer subdivisions with simple gable and hip roofs, plus retail and hospitality along the Pooler Parkway corridor. Straightforward metal jobs, priced accordingly.
Industrial and logistics buildings near the terminal. Large R-panel roofs and metal-over-metal retrofits are the everyday work here.
Home base. Marsh-front and Ogeechee River homes where wind and salt both matter, so 24-gauge aluminum-zinc with tightened clip spacing is the default.
Effingham County residential growth plus light commercial. Far enough inland that the salt load eases, close enough that we still spec for it.
Rural and semi-rural properties, outbuildings, shops, and agricultural structures. Screw-down and R-panel do a lot of honest work out here.
We also cover Hinesville, Statesboro, Brunswick, Tybee Island, and across the river into the South Carolina Lowcountry. Full map on our areas we serve page.
Comparing bids
Metal roofing companies in Savannah are not interchangeable, and two quotes for the same roof can differ by 40% because they are describing different roofs. Seven things separate a real metal bid from a cheap one. Ask every roofer you talk to, including us.

Frequently asked
Residential standing seam runs $12.00 to $22.00 per square foot installed. Commercial standing seam runs $11.00 to $18.00. R-panel runs $7.00 to $11.00 and screw-down corrugated runs $5.00 to $8.00. A 2,400 square foot house in standing seam comes to roughly $28,800 to $52,800. A 20,000 square foot commercial building runs $215,000 to $345,000. Panel gauge, seam height, deck condition, trim complexity, and finish all move the final number.
A properly installed standing seam metal roof with a PVDF finish lasts 40 to 50 years in Coastal Georgia. R-panel and other exposed-fastener systems last 25 to 30 years. Screw-down corrugated lasts 20 to 25 years. Exposed fasteners are what shorten the life: the neoprene washers under the screw heads age out and back out long before the steel gives up.
Coastal Roofing of Georgia installs residential and commercial metal roofing across Savannah and Coastal Georgia from our base in Richmond Hill, GA. We are licensed in Georgia and South Carolina. When you compare Savannah GA metal roof installers, ask each one for panel gauge, substrate coating, paint system, clip spacing basis, and underlayment type in writing. Those five answers tell you more than the price does. Call (912) 312-0507 for a measured quote.
Not when the roof is specified for it. Salt air accelerates corrosion at exposed edges and at any point where two different metals touch. The fix is aluminum-zinc coated steel rather than plain galvanized, fasteners matched to the panel metal, sealed or hemmed cut edges, a barrier between panels and pressure-treated lumber, and a freshwater rinse of sheltered areas that rain never reaches.
Plan on 6 to 10 weeks from contract to final walk. Most of that is panel fabrication, which typically runs 4 to 6 weeks because metal is made to your building's dimensions. Actual crew time on the roof is 3 to 7 days on a house and 1 to 3 weeks on a commercial building. Historic district projects add review time before fabrication can start.
On any building you intend to keep, yes. Standing seam costs more up front and lasts 40 to 50 years because no fastener ever penetrates the panel face and the panels are free to expand and contract. R-panel costs less and lasts 25 to 30 years, with a re-fastening pass every 10 to 15 years along the way. R-panel is the right answer on warehouses, metal buildings, and agricultural structures where cost per square foot is the deciding factor.
Yes, but only in profiles the Historic Review Board has approved. Seam height, panel width, color, and finish all have to fall inside the approved palette, and copper, zinc, or terne-coated stainless is sometimes the required material. We handle the Certificate of Appropriateness process as part of the project, including the color submission and the review meeting.
Often, yes. Metal over an aging exposed-fastener metal roof is common and uses a sub-purlin framing system, which avoids tear-off cost entirely. Metal over asphalt shingles is allowed in most jurisdictions when total layer count and dead load stay within the structure's capacity. Metal directly over TPO or PVC membrane is not something we recommend. We inspect the deck and confirm code before signing off on any recover.
Not with a PVDF finish. PVDF is the same fluoropolymer chemistry used on aerospace coatings: UV-stable, chalk-resistant, and warranted 30 to 40 years against fade and chalk by the coil coater. Cheaper SMP finishes typically carry a 25 year warranty and fade noticeably within 12 to 15 years in Coastal Georgia sun.
A concealed-clip standing seam roof is one of the most wind-resistant assemblies available, reaching FM Global 1-90 class uplift ratings and better when clip spacing follows the panel manufacturer's wind-zone tables. Spacing tightens at eaves, rakes, and corners where uplift pressure peaks. We spec to Coastal Georgia's wind zone rather than an inland default.
