Standing seam metal roofs
Concealed clips, no exposed screws, and panels that run eave to ridge in one piece. On the coast we lean to mechanically seamed panels over snap-lock. Here is why: a seam folded shut by machine holds against uplift that can pop a snap-lock seam open, and once one seam opens the wind has a handle. Most of ours are 24 gauge steel or .032 aluminum with a 1.5 or 2 inch seam. Snap-lock is fine on a sheltered porch.
