Help! from Canada.

Leaking roof lacks counter flashing for stucco.
Hi- I stumbled across your website when searching Google to try and solve a problem. It looks like you really know your stuff! I'm hoping you may be able to help me.
I'm a builder from Winnipeg, Manitoba, Canada. We have had a re occuring issue on an addition we built for a client a year and a half ago. I've had the roofers back three times, as well as the stucco contractor, and nobody can figure this issue out...
I have the existing roof meeting on the downslope into the new addition wall. I'm kicking myself in the ass because I'm thinking that partially, this is a bad design.
On the new addition wall, we have step flashing all the way down with a kick out at the bottom which is supposed to send the runoff into a tiny piece of trough. Somehow, the water is trailing in behind that and running in the stucco down the wall on top of the exterior door below. At least I think it's trailing in behind the stucco. There's always a long wet mark anytime it rains or when ice melts after winter.
I've attached a photo taken just a couple of days ago and a couple from further back so you can see the way it's built. Perhaps you can help us figure this out? We don't like to leave issues like this and take them seriously.
I look forward to hearing from you

The need for counter flashing at roof intersections.

I have written about this before, And am providing a link to my article I wrote in 2010. I like the picture. It is like an insurance company commercial saying "Don't let this happen to you ! Here's my link:

Counter flashing is for brick, not stucco in Chevy Chase.

Stair step flashing made for bricks doesn't work for stucco. On a brick application, the tops of the steps are bent into the brick joint. On stucco, the flashing must go under the stucco.

Lack of flashing causes rot in this stucco in Chevy Chase, Maryland

Incorrect flashing and lack of kick out caused this rot in the sheathing and framing. The whole wall buckled requiring the stucco to be replaced.
