Standing Seam Metal Roofing in North Georgia

Standing Seam Metal

Standing seam versus exposed fastener. They are not the same roof

"Metal roof" covers two different products, and the price gap between them is not padding. Standing seam panels lock mechanically at raised seams and attach through concealed clips, so no fastener penetrates the panel face. Because the panel isn't pinned rigidly, it expands and contracts with temperature without stressing a fastener. Properly installed, it's routinely a 40 to 60 year roof.

Exposed fastener panels, ribbed, 5V, corrugated, are screwed directly through the face and sealed with rubber washers. They're a legitimate, lower cost option, but every washer is a wear part. Georgia's UV and heat cycling crack them in roughly 10 to 15 years, turning hundreds of penetrations into potential leak points.

Our standing seam is a snap lock system with 1.5 inch ribs. The panel edges snap together over concealed clips, so no fastener goes through the panel face. When you compare metal roofs, ask for the seam type and the rib height, and ask whether there are exposed fasteners anywhere on the panel field. The answer should be specific.

What drives cost

Panel gauge and material (steel or aluminum), seam type, finish system (Kynar/PVDF holds color far longer than baked enamel), and roof geometry. More hips, valleys, and penetrations mean more seams, trim, and labor per square.

What goes wrong

Panels fastened too rigidly with no allowance for thermal movement crack or oil can. Dissimilar metals in contact set up galvanic corrosion that eats through the lesser metal over years. Clips spaced too far apart let panels rack in wind.

One of these has no fastener through the panel. The other relies on a rubber washer that is, by design, a wear item.
