Newly constructed home in So Central Colorado foothills with some heavy snow and rain, then long periods of drought. Metal roof with 9/12 pitch, stuccoed chimney and dormers. Should trim flashing be under or on top of roof panels? Ours are under along dormers and chimney. Regional Building Dept does not have code as they say they have to go by roof manufacturers specs and usually do not have them. Having dispute with builder and need info to show Regional so they can back me up.

Any manufacturer of quality metal roofing will have these sort of standard details available based upon the design of their roof system.
It will vary according to system but, commonly, except for the uphill side of a chimney, there will be a flashing on top of the roof panels. There may be a flashing beneath them as well.

That is pretty standard.
Make sure the metal product you're using is approved for that low of pitch.
Mount the flashing high rather than too low -- you do not wnat the flashing to create a negative pitch.
Use some sort of closure strip at the top of the metal panels -- check with the manufacturer to see what they offer.
