Who did the detailing on the external corners and upstands for your dormers as they're incorrect and leave you exposed to weathering. . Ideally, you're going to need some flashing over the corners and upstands to resolve this.

 

Here are the recommended details together with examples of upstand and welted/soldered corners:

Sorry to disagree there.  The detailing on the sides of the Standing Seam is correct. No weather can get in there.  Flashing is an option but it doesnt look as good, better to form the flashing from Panels .

These are the areas I was referring to, especially the external corner, but the upstands at the junction between the roof and the bottom of the dormer are too low .

Too low for what purpose. Apologies for my lack of understanding but there is cladding going on the entire dormer and a window cill integrated flashing on the bottom. How would you imagine water getting into these sections. 

There are several ways to approach a metal roof , it all depends on the setup and rest of the building .

Thanks for the good advise but the detailing is spot on 👍
