The point of standing seam is that no fastener goes through the weather surface. Everything else about the system follows from that.
In detail
Standing-seam metal roofing
Panels are fixed with concealed clips at the seam rather than screwed through the face, so there is no gasket to perish and no fastener hole to open up as the metal expands and contracts. Those clips also have to let the panel move — a long run can grow and shrink measurably between a January night and an August afternoon, and a panel pinned at both ends will oil-can or tear its own fixings out. On longer runs we use sliding clips for exactly that reason.
Underneath goes a high-temperature underlayment, because metal runs far hotter than shingle and an ordinary synthetic will not survive it. Valleys, hips and ridges are formed in matching metal, penetrations get purpose-made boots rated for the temperature, and every seam is rolled on site. Done properly the roof outlives two shingle roofs; done with exposed fasteners and no allowance for movement, it is a shorter-lived roof that cost more.

Questions
Asked most aboutstanding-seam metal roofing
Is a metal roof worth the extra cost over shingles?
On a long horizon, usually. Standing seam typically costs two to three times an asphalt roof and lasts well past two shingle cycles, so the arithmetic works if you are staying. It also suits some houses far better than others — on the wrong architecture it reads as agricultural, and that is a judgement we will give you honestly before you commit.
Are metal roofs noisy in rain?
Not on a house. The noise people remember comes from metal over open purlins with nothing behind it — a barn or a porch roof. Over solid decking, underlayment and an insulated attic, a standing-seam roof is no louder than asphalt.
