Does the 12/2 minimum pitch rule for shingles still apply if peel-n-stick is first applied to the roof deck? Why would I have to put down a membrane on 12/1 pitch above the porch, instead of shingles, if there is peel-n-stick? And then can't I just install the shingles right over the peel-n-stick? I just want the whole roof to look the same. I live in FL.

If there are not asphalt shingles and it meets the manufacturer specs for install, I can't find why not but you may still need to get it approved.
