Acceptable?

The other roofer is correct. At least some of that work needs to be redone. It is no disgrace to do rework, well not much, and better than the consequences. In my youth, we would have used painted metal valley flashing and laid the shakes over, keeping the nails high, as long as there was over 4:12 slope.
If there are areas with lower slope, maybe torch-on membrane. But that is a design screwup, such as where the dormers meet. Chimney in the valley, etc. The architect should take some of the blame, IMO. Too late now, but he or she should be chastised.

Kick-outs were formed with the mortar.


That ought to work real well until it rains.

You will not get 40 years out of a wood shingle roof. Lucky to get 18. Idaho has worse winters than here in Kansas. You may get 15. Think snow when you look at these areas also.

Those are split shakes, Gary, tougher by far than sawn shingles. Kept clear of moss and leaves, in dry country Utah, they should be good for 30-40 yrs. Unless there are poor grade shakes in the batch and good cedar is getting rare even here where it used to grow everywhere. We sold it all.

The problems with that roof originate with the architect.
