Most metal roofs can be used down to 3:12 pitch (including metal shingles) and some vertical seam roofs can be used down to 2:12. For pitches lower than 2:12, you definitely need a mechanically seamed stranding seam.

what is the min. pitch for a metal shed roof ? it is going to be put over a front porch; the house has a 11/12 pitch.
I am worried about snow load.
