Unfortunately, I have roofers that failed to gap plywood, made leaking plumbing penetrations, dropped ply off the roof, had metal fly off the roof overnight in a windstorm (two separate times) hitting the sidewalk, and used power cords as safety lines.
So now we're at the bath vent.
How can I check they're doing it right?
I can't trust that the roofers know.
Should this be installed connected to a panel but not the deck? Screwed through the deck? Installed by cutting a panel and installing shingle style?
The panels are 17 foot Metal Sales Image II residential.
Each panel has oval slotted screw holes, but no sliding clips.
The Image II installation manuals are silent on the topic.
The proposed bath fan is Famco model PBKX

Or copy this URL: https://www.metalroofing.com/spirit/comment/24694/find/I would try to lay out the roof so the pampered vent is located between the metal roof panel ribs, hopefully not in the middle of a rib. That said, you need space down both sides of the vent and the adjacent ribs for water / snow to get by. Then I would try to not split the metal roof panel but, yes, fasteners will go through the standing seam and into the decking. Other folks may have better ideas so perhaps you will get some other input here.
