How much does metal roofing material cost, and what drives the price?
Short answer. Metal roofing material cost depends on the panel system, the metal's thickness, and its coating: thin exposed-fastener panels with basic paint are the least expensive, while thicker standing seam panels with premium fluoropolymer finishes cost much more. Trim, closures, fasteners, clips and high-temperature underlayment add a meaningful share on top of the panels themselves.
Panel system
- Exposed-fastener panels. Wide panels screwed through the face. Least expensive, but the screws and washers need checking and eventual replacement.
- Standing seam. Narrower panels joined with raised seams and concealed clips. More material and more expensive, with no exposed fasteners in the field.
- Metal shingles and shakes. Stamped panels that imitate other materials, typically priced at the upper end.
Thickness
Steel thickness is given as gauge, and a lower number means thicker metal. Thin panels are common on sheds and barns, while residential standing seam usually uses thicker steel that resists denting and oil canning better. Thicker steel costs more.
Coating and finish
- Metallic coating: zinc (galvanized) or aluminum-zinc on steel protects against rust. Aluminum panels cost more and suit corrosive sites.
- Paint system: standard polyester-based paints cost less, while fluoropolymer finishes hold color and resist chalking much longer in strong sun.
- Reflective colors can lower roof surface temperature in Georgia summers.
The rest of the materials list
- Ridge, hip, valley, eave, rake and wall trim.
- Foam closures, clips, fasteners and sealant.
- Underlayment rated for the heat under metal.
- Pipe boots and flashing designed for metal.
Material is only part of the installed price; skilled labor for metal is a large share. See metal roofing in Georgia and synthetic underlayment vs felt.
