Quick Answer
Coastal Roofing of Georgia (CRG) installs commercial metal roofing across Savannah and the Coastal Georgia region. We use standing-seam, R-panel, and screw-down systems on warehouses, retail, schools, churches, and industrial buildings. A correctly installed standing-seam metal roof lasts 40 to 50 years and stands up to hurricane wind, salt air, and intense UV. Call (912) 312-0507 for a free metal roof assessment.
Why Metal
Metal is the longest-lasting commercial roof system installed in Coastal Georgia. A correctly installed standing-seam metal roof reaches 40 to 50 years of service life. Galvalume and Kynar-finished panels hold their color and corrosion resistance through decades of salt air, humidity, and tropical-storm exposure.
For commercial owners in Savannah, metal solves four problems at once: it sheds water on shallow slopes that membrane roofs fight, it handles 130+ mph hurricane uplift when properly fastened, it reflects 70% of solar radiation when finished in cool-roof colors, and it carries Class A fire and Class 4 hail ratings without modification.
The trade-off is upfront cost. Commercial metal runs $11.00-$18.00 per square foot installed in Savannah — roughly 2x the cost of TPO. Owners running the math at 40-year life typically find metal cheaper per year than any single-ply alternative, especially when energy savings and lower maintenance are included.
Metal Roof Types
Standing-seam metal roofing is the premium commercial choice. Vertical legs lock together with a concealed clip, hiding fasteners under the seam and giving the roof a hurricane-rated weather seal. Coastal Roofing of Georgia installs standing-seam in 1.5", 2", and 3" rib heights, with snap-lock or mechanically seamed profiles depending on slope and exposure. Standing-seam is the right choice for commercial buildings with slopes from 1:12 up.
R-panel and PBR-panel metal are exposed-fastener systems most often used on metal buildings, agricultural facilities, and large warehouses where cost matters more than aesthetics. They install fast and run $7.00-$11.00 per square foot. The trade-off is fastener gaskets that need monitoring — those neoprene washers fail before the panel does, especially in coastal humidity. We re-fasten and re-gasket R-panel roofs on a 10-15 year cycle to keep them watertight.
Metal shingles mimic asphalt or slate appearance with a metal substrate. They're a residential or small commercial choice — most often used when an owner wants the look of a traditional roof with metal's longevity and impact resistance. Available in interlocking diamond, slate, and shake profiles.
Screw-down (corrugated) metal is the lowest-cost system at $5.00-$8.00 per square foot. Exposed fasteners go through the high ribs into the deck or purlins. We install it on barns, outbuildings, and budget commercial structures where life expectancy is 20-25 years rather than 40+.
Colors and Finishes
Color choice on a commercial metal roof affects energy bills, building temperature, and the manufacturer's warranty. The Kynar 500 / PVDF finish is the industry standard for commercial metal in Savannah — it carries a 30-40 year fade and chalk warranty and meets Cool Roof Rating Council (CRRC) reflectance standards.
Cool-roof colors we install most often on Coastal Georgia commercial buildings: Galvalume Plus (mill finish, highest reflectance), Regal White, Solar White, Sandstone, and Slate Gray. Darker colors (matte black, dark bronze, hunter green) look striking but absorb significant heat — fine for cooler climates, not ideal for low-slope commercial buildings on the coast.
The SMP (silicone-modified polyester) finish is a budget alternative with a 25-year warranty. Suitable for ag and outbuilding use. Not what we'd put on a commercial building owner expects to keep for 40 years.
Installation
A typical Savannah commercial metal install runs 1 to 3 weeks per building, depending on size, slope, and whether we're tearing off an existing roof or installing over a deck. Our process: site assessment with measurements and color sample sign-off, panel order with 4-6 week lead time, scheduled tear-off (or recover-over if the existing deck and slope allow), substrate inspection, underlayment installation, panel installation, then flashing details at parapets, curbs, and edges.
Coastal Georgia detail work that matters: every penetration gets a curb-mounted flashing, never a pitch pan; every panel termination at a parapet or edge gets a continuous closure strip to keep wind-driven rain and insects out; hurricane-clip spacing follows the panel manufacturer's wind-zone spec, not the minimum building code. We document each step with rooftop photos delivered to you on completion.

Buildings We Roof
We've installed commercial metal roofing on warehouses along the Port of Savannah corridor, retail strip centers in Pooler and Garden City, school buildings, churches across Chatham and Bryan counties, industrial facilities in Statesboro and Hinesville, and historic-district commercial buildings in Savannah's HRB-controlled zone. Metal works on all of them — the right profile and color choice changes by building type.
Warehouses: standing-seam in 24-gauge Galvalume Plus, snap-lock profile, with continuous insulation under for energy savings. R-panel as a budget alternative when life expectancy is the priority.
Retail and offices: standing-seam in Kynar-finished color matched to building branding. Architectural curved panels available where roofline aesthetics matter.
Schools and churches: standing-seam in 24-gauge with mechanically seamed profile for the highest wind rating. Lower maintenance cost matters for these owners.
Historic district (Savannah): copper, zinc, or terne-coated stainless on appropriate buildings. We handle the HRB / COA application process.
Frequently Asked
A commercial metal roof in Savannah costs $11.00-$18.00 per square foot installed for standing-seam, $7.00-$11.00 for R-panel, and $5.00-$8.00 for screw-down (corrugated). For a 20,000 square foot commercial building, that works out to $220,000-$360,000 for standing-seam, $140,000-$220,000 for R-panel, and $100,000-$160,000 for screw-down. Final price depends on slope, deck condition, panel color/finish, edge complexity, penetration count, and warranty term.
A properly installed standing-seam metal roof in Coastal Georgia lasts 40 to 50 years. R-panel runs 25-30 years. Screw-down (corrugated) runs 20-25 years. The biggest factors that shorten metal-roof life in Savannah are coastal salt air, fastener gasket failure on exposed-fastener systems, and standing water on inadequate slopes. Standing-seam with Kynar 500 finish is the longest-lived option for commercial owners on the coast.
The most energy-efficient metal roof colors for Savannah are Galvalume Plus (mill finish), Regal White, Solar White, Sandstone, and Slate Gray — all in Kynar 500 / PVDF finish. These cool-roof colors reflect 50-70% of solar radiation and meet CRRC standards. They reduce summer cooling loads and extend roof life. Darker colors (matte black, dark bronze) absorb significant heat and aren't ideal for low-slope commercial buildings on the coast.
Yes — standing-seam metal roofs install in Savannah with hurricane-clip spacing engineered for the building's wind zone (typically 130-150 mph for Coastal Georgia). Mechanically seamed standing-seam carries the highest uplift rating available in a commercial metal system. Coastal Roofing of Georgia follows panel manufacturer wind-zone spec (not just minimum building code) on every coastal install.
Sometimes — depends on the existing roof and your local building code. A metal-over-metal recover is common on R-panel buildings using a continuous batten system. Metal-over-asphalt-shingle is allowed under most jurisdictions if total layer count and weight stay under the deck's structural capacity. Metal-over-TPO or PVC is usually NOT recommended — single-ply membranes don't provide adequate substrate for a long-life metal install. We inspect the existing deck and confirm code compliance before recommending a recover.
Coastal Roofing of Georgia is a commercial metal roofing contractor based in Richmond Hill, GA, serving Savannah, the Coastal Georgia region, and the South Carolina Lowcountry.

Commercial metal roofing typically uses heavier-gauge panels (24-gauge vs 26-gauge residential), wider panel coverage (16-24 inches vs 12-18 inches), and is engineered for low-slope applications (1:12 to 4:12). Commercial standing-seam uses mechanically seamed profiles for higher wind ratings on flat-to-low-slope roofs. Residential metal more commonly uses snap-lock standing-seam, exposed-fastener panels, or metal shingles on steeper 6:12+ slopes.
A commercial metal roof installation in Savannah typically takes 1 to 3 weeks per building, depending on size, complexity, and whether we're tearing off the existing system. Add 4-6 weeks for custom panel manufacturing lead time before the install starts. Total project timeline from contract signing to completion is usually 6-10 weeks. We schedule installation around your business hours to minimize disruption.
