TL;DR
A standing seam is the raised interlocking joint between adjacent metal roof panels, formed by folding or snapping the panel edges together one to two inches above the drainage plane. Elevating the seam keeps fasteners and the joint itself out of flowing water, which is the design's core advantage over exposed-fastener metal roofing.
What it means
A standing seam is the raised interlocking joint between adjacent metal roof panels, formed by folding or snapping the panel edges together one to two inches above the drainage plane. Elevating the seam keeps fasteners and the joint itself out of flowing water, which is the design's core advantage over exposed-fastener metal roofing. Mechanically seamed profiles are crimped shut with a powered tool for the highest wind and water ratings, while snap-lock versions join by hand.
