i have noticed some standing seam roof where the panels in the valley are folded inward. Is this better than just cut panels? would cut panels be ok if there was some sealant tape underneath?

On standing seam we hem the panels. No cut edges are supposed to be exposed. Rust will form on the cut edges.

I have to disagree with Wade on this one. You can have the exposed edges showing. It's not as good, or as pretty, but it is an accepted way to do it for many types of standing seam. Generally the valley panels are hemmed and hook around an offset cleat in the valley. You can also simply cut them at the angle of the valley, but if you do this you will have to fasten the panels down with screws. I don't like this method as well, especially for standing seam, but it can be done. (See the attached drawings)

Nate, I was just stating the way it is supposed to be, it doesn't have to be that way. If someone is actually putting on a standing seam instead of a panel with the screws exposed I can't understand them not wanting it to look "pretty".

Locking the panels into the valley is the generally accepted better way to go.
