I have a client who wants an addition, the addition needs to have a roof slope perpendicular to the existing. Existing roof is metal with about a 3:12 pitch to a guttered eaves. The additon will have a similar pitch. There will be a stucco’d parapet wall between the two roof systems. So I will have a metal roof pitch terminating into a 16′ wide parapet wall. I am playing around with crickets and different materials and am just wondering if anyone out there has had a similar condition and what sort of solution was used.
Thanks.

If you forget the parapet wall between the two roofs, they will meet in a nice valley. No need to create a problem where there isn't one
It would be interesting to see what kind of sight lines this house and addition will have.
Are there similar features elsewhere on the house, or a special reason the client wants this look?
It looks like the wall extends above the roof on three sides? How high will this be and how high is the existing roof? What kind of metal roof is on the house? How old is it? is it still available?
seems like a few ways.
add cricket (or extend new roof) so that the existing covered roof drains to the left, in the direction the addition will drain.
Add cricket that drains to the right, or the opposite of where the addition will drain.
Or split the difference. all these will likely have visible signs, and challenge capture of the gutter runoff at one or two points.
You could also consider a built-in gutter, which would be expensive to do right, and be fraught with future servicing issues. If there are ice and snow to deal with, it needs to figured in.
You might want to engage with an architect, or find some software to show the client a couple options and discuss them.
