metal roof flashing

I have been trying to research the flahsing on the edge of this roof and i can't decide if this is correct or not, my gut says no. I found this setup in many locations on the roof.

On a practical side the rake trim (factory formed) is performing what it is designed to do. Which is to finish off the edge and cover the edge of the roof panel. But the channel that is formed may not account for excess rain flowing through it. It is possible that the trim and the ridge are sealed, preventing water to flow over the ridge and onto the rake edge. How it may be sealed is a good question. There are some great Butyl caulk sealant on the market, though expensive.

The installation may work fine and never have an issue. Though taking a belt and suspender approach to address the unknown possibility, capping over the flat channel between the ridges running (extending capping) to the ridge would resolve any future concerns. Which would be my suggestion to resolve any concerns. Though it may create and aesthetic issue to some.

Cory,

I would agree with Garry Sorrells, the rake trim is doing what it is intended to do. Assuming the primary seam, shown to the right of your arrow, continues all the way to the bottom of the slope there should be no problem with this condition.
