If all was well With the proper flashing/lead/cricket how would you as a professional roofer go about shingling this A/C unit (Cutting the main roof)

in Detail Which Shingles would you put on in Order
which position would the shingle be placed to meet its proper spot with the flashing
were talking about at the Top corner of this A/C unit to meet into the cricket to create your Weave then to continue up the Cricket cutting the main in the end. You would have your first piece of step flashing on top the lead at the bottom of the cricket

Edit:
Sorry if confused
"You would have your first piece of step flashing on top the lead at the bottom of the cricket"
Meant to say "first piece of lead on top the lead for the 2 corner pieces or if u wanted just the cricket corner piece with the side corner as step flashing roofing varies

Go to the NRCA Steep roofing manual and get the correct detail or hire a professional roofing contractor. From what you are showing it is hard to even tell what you are trying to do.

Impossible to describe in words. Though it would be no different from a chimney flashing. Contact the NRCA at www.nrca.net and ask them for detail No. 3.6.4, 3.6.4.1, & 3.6.4.2 These are from the NRCA 5th Edition manual.
