Completed the right side Mansard including the first chimney install. I used gel CA to hold the chimney in place. I flashed the lower portion where the chimney entered the sheathing, and also flashed the window to its right. And I just noticed in this image that the round window is not longer in contact on it's right side. I'll have to fix that.
Up to the point where the chimney and the roof are not in contact, I shingled both sides. Then I fed a single piece behind the chimney for a few courses until it again made contact with the upper reverse curve. This was a "Two-Tweezers" job to slide it through and manipulate it to keep it all squared.
When I got to the top course I again used a piece of starter strip to finish it off. In this care I had to cut eyebrows out so it would snug against the window. I was tired of estimating this curve by eye and made a template out of some thin ply.
I tucked the strip up to the chimney's edge and then noted the center of the curve. After cutting the piece just dropped in nicely. I ended the session by shingling the right side of the right-hand window and putting flashing on the left rear window. I greatly underestimated the amount of copper I would need. When I estimated the strip length, I neglected to add the amount of overlap between each piece of flashing. I'll need to treat another batch almost the same size as the first. I may make the pieces longer since they don't have to correspond to the flashing length.
If you're eagle-eyed you'll notice some areas that need some touchup NATO Black paint. That will all be taken care of when all the shingling is complete. If I don't finish this tomorrow, I will make a big dent. The rear roof is simpler than the others without the chimneys.
