Slate to Metal Seam Transition

[Barney12]

As my frame delivery gets closer its amazing how you start to doubt/worry about small items of detail!

This particular issue is the latest!!

 

Our North roof elevation is a little unusual as its a "cat slide" roof (two story at the ridge all the way down to single story by the time it gets to the eaves). To make it a bit more unusual it changes from slate to metal seam at the point the angle changes!

 

Here's a snapshot of the roof build up:

 

 

If you zoom in its this transition that is vexing me:

 

 

What this shows is that my OSB deck (for the metal seam) is going to be pretty much at the same finish level as the batten for the tile.

Thus by the time the metal seam roof is on, followed by a lead flashing I'm worried that there will be too much kick on the last tile which will look odd?

 

Can anyone with more experience pose a view?

 

One option would be to reduce the batten under the OSB to 25mm (from the current 50mm) but would that be enough of a ventilation gap?

Or should I get MBC to pack (by an increasing amount) the last three rows of batten to stop the kick all being on the last tile?

 

Or am I just over worrying about the detail!!

 

Many thanks in advance!

Will you actually notice it? I worried about things like this but now I probably cant even remember what they were!
