To flash or not to flash?

This is the top peak of a shed roof, I think that the flashing should be on top od the shingles. Any comments.

sorry about the pic posting

It works better leaving the metal exposed. If they would have ran a ridge cap sideways with a 1 inch overhang on the top edge, it would have been better and still covered the metal.

I’m with you on this. See Page 64, Figure 6-16, ‘Topping off flashing on a single pitch roof’ of Certainteed Shingle Applicator’s Manual:
