I had some roof leaks and hired a roofer for repairs. The repair involved replacing the flashing along a wall to roof connection, so he removed a row of tiles on the roof, then cut and chiseled out the existing stucco on the wall back to the wood sheathing to install the membrane and flashing. Once the flashing is done he installed the cement roof tiles, and put roofing tar on top of the flashing where it meets the old stucco.


His contract does not include redoing the stucco, that's for me to finish.


Now I am wondering, how would I even attach metal lath to the flashing? and will stucco bond to this roofing tar at all? Or do I need to break and remove more stucco or even to the top of the wall so I can attach lath higher up?

You have a mess there. I would start all over again & get a roofer that knows how to do flashing correct.
Stucco will not adhere to the tar.
The Stucco should be at least 2 inch above the finished roof tile.
A better fix would have been the use of peel & stick under the existing water barrier & than another peel & stick over the flashing.
At this point I would cut the existing stucco NOT the lath up say about 6 to 8 inches than break off the stucco leaving the lath & water barrier than cut the lath back say 3 to 4 inches leaving the barrier than install a new barrier or peel & stick under the existing. Than install a Stucco casing bead stair stepped to maintain 2 inches above the tile than lath & new stucco.
What are you going to do where the tile & flashing are above the window / door frame? The flashing is a water leak waiting to happen.

I am asking the roofer to install a kick out flashing there to direct water away from the corner of that window then install gutters below.


The stucco there is very thick and uneven, over 2 inches thick in some spots. I have a feeling in the past someone might have applied an additional layer of stucco over existing stucco to fix a leak, then the put a new metal flashing in on over the textured stucco wall, and I could see many attempts to fix over the year with silicone, tar, even foam.



So last week a roofer came to tear all that out to redo all the flashing and tiles around there. I tested with a garden hose and it's not leaking under to the ceiling anymore. The reason I think there is a build up layer b the crew used a 4.5" angle grinder diamond wheel to cut the stucco and it bottoms without cutting all the way through, so he had to hammer and chisel the remaining depth. I wish he folded up the old wire lath instead of cutting them off. It's going to be hell to cut that stucco back another 4" higher...I can't even find masks anymore LOL.
