Roof design for part glazed pitched roof

[d438a1]

Hi there, 

 

I'm just finishing designing a new roof which is going on an extension and wanted to check to see if anyone had any better ideas for how to weatherproof where I have adjoining cedar shingles and glazing. I've attached a few photos which hopefully are clear.

 

The red is the underlay and the dark grey is either going to be lead (or lead alternative) flashing or I may get it made up in aluminium. I think the way I've detailed works, but open to alternative ideas! I've also attached photo showing the glazing bar end cap. Part of the reason for the way I've design is also to make sure I can somewhat easily replace the glass if I need to.

 

Thanks
