General question about metal roof

Those of you that have a metal roof, or have experience with them I have a question. Was it vaulted so water would drain off efficiently, or did it have indents/valleys etc. that just retain water when it rains. Inquiring minds want to know.

p.s. By vaulted, I mean, pitched someway so water would drain well. I do not know how you can to this with metal.

We had an older one (mid 80's) that was "crowned" a bit. But not enough. Where the roof meet the trim of the skylight it formed a "bird bath".

So yes, it was "vaulted" but not enough to shed all the water that sat in the little dip. Not good to have caulking under water 24/7.

I filled up the bird bath with pro-flex out of a quart container and solved problem for about 5 years.

I would do metal roof again. A lot easier to keep clean. Although when it rained it sound like I was in a steel drum.
