I have a cement tile roof with parapet end walls (stucco). The roofer put only a 4
inch flashing along the wall and needless to say it leaked. He came back to fix it
by removing a couple of rows of tiles along the walls and applying some roof mastic
on the flashing overlapping the roof surface. It worked—–for a while. Now he’s
long gone and some of my sheetrock is growing mold! What can I do to fix this
once and for all?

Get a real roofer to do it right.
You will have to remove tile back from the wall 3-4 feet all the way up, then flash it properly. If the tarpaper is single ply you need at least a double of 30# on the whole roof. I&Wshield is better.
Then a flashing with return on it on the base and the verticle flange to be tall enough to be 4" above the height of the tiles, overlaid with tarpaper under the wall surface.

Thanks for responding, Piffin. I've already got I&W shield on the decking. Since the
stucco covers over the vertical leg of the flashing I'd have to install new flashing
on top of it. Doing so might be tricky because the walls are ICF's and I'm not sure
how I'd fasten the new flashing to the wall. Holler if you've got an idea.
Thanks
With I&W already on the deck, I can only picture two ways for water to be getting in, and I would have to know more about what conditions make it more apt to leak. Like High wind, or only in heavy rains, etcBut you said the cieling is showing stains - not that you see it actively leakingThat makes me wonder if there is an active leak or leftover water, or a cxondensation problemAnyway, for a leak, my first thought goes to ask if there is tarpaper in that wall, over the flashing and under the stucco, and how is the wall capped.In other words, this might not be a ROOF leak
