Metal Roofing Installation in Marietta, GA
Metal roofing has gone from agricultural barn material to one of the most popular premium residential roofs in Marietta, GA. The combination of 50-year service life, factory color that holds for decades, and the modern look of standing seam panels has made it the default choice on a lot of new custom homes and high-end re-roofs in Cobb County.
We install standing seam for residential and exposed-fastener panels for outbuildings. Both with 24-gauge steel and factory Kynar 500 finishes that hold color and resist chalking for 30+ years.
Standing Seam vs. Exposed Fastener Metal
Standing seam, hidden fasteners
The premium residential option. 1.5-inch raised seams with the panels mechanically clipped or snap-locked to hidden fasteners along the seam. No exposed screws to back out, no gasket to fail. Clean, modern look that pairs well with both modern and farmhouse-style homes. This is what we install on every home.
Exposed-fastener panels (R-panel, 5-V crimp)
Half the cost of standing seam. Screws driven through the panel face into the deck or purlins with a rubber gasket. Fine for barns, sheds, agricultural buildings, and outbuildings where the look isn't the point. Gaskets need replacement every 15 to 20 years.
Why 24-Gauge Steel and Kynar 500
Cheap metal roofs use 26-gauge or 29-gauge steel and polyester paint finishes. The thinner steel oil-cans (waves visibly between fasteners) and dents easier. The polyester paint chalks and fades in 5 to 10 years. We use 24-gauge steel for stiffness and dent resistance and Kynar 500 (also called PVDF or Hylar 5000) coatings that hold color for 30+ years and carry manufacturer warranties to match.
The Underlayment System Under Metal
Metal panels expand and contract more than shingles, which makes the underlayment more important. We use full-coverage synthetic underlayment, ice-and-water shield in valleys and at every penetration, and high-temp self-adhered membrane under any low-slope sections. This is the layer that actually keeps water out if a panel ever moves out of position.
What Metal Roofing Costs in Cobb County
Standing seam runs $10 to $16 per square foot installed depending on panel width, color, and trim complexity. Exposed-fastener panels run $6 to $10 per square foot. Roughly twice the cost of architectural shingles, lasts roughly twice as long, and the warranty on the factory finish runs three times as long. Long-term cost per year of service life is comparable.
Common Questions About Metal Roofs in Georgia
Will it be loud in the rain?
No. Properly installed over solid decking with underlayment, metal sounds the same as a shingle roof from inside the house. The barn-roof-in-a-storm sound comes from metal installed over open purlins with no decking, which we never do on residential.
Will it interfere with cell signal or Wi-Fi?
No measurable degradation. Cell signals and Wi-Fi pass through metal roofs without trouble.
Is it more energy efficient?
Yes. Reflective Kynar finishes (especially in light colors) reflect more solar heat than asphalt shingles. Most homeowners see a 10 to 20% reduction in cooling costs after switching to a reflective metal roof.
