   If I'm reading you right it should be both.

   The masonry sub will install flashing as they lay the stone.

   The roofer will install step flashing to the brick layers flashing.

   But the through wall flashing will be the Mason's responsibility correct?

   Yeah, what Dan said.

   The mason will install his flashing above the roof line. It will be imbedded in the stone and turn down. If you have to cut it in later it will look like it was added later. (which it would be) The mason can can use the right stones while installing to make it look better.

   Then the roofer will install his step flashing from the roof to make it water tight.

   Like I said, you do it like a chimney (the side of one at least):

   Thats a good pic of what he needs. I try to find stuff like that but I dont have much luck.

   I'm thinking on a stone wall, if the mason doesnt install it then it will never look right.

   Yeah, the pieces behind the flashing need to have relatively flat faces, or the flashing won't fit well. And it's a beech to have to grind away the stone because the mason didn't set in flat ones.

   That is not THROUGH flashing.From what I have heard stone should be THROUGH flashed.I could not find a picture of it. But I think Mike Smith might have one posted one in progress.This is a close as I could find.http://www.crsmca.org/publications/featured-article

   Seems like through flashing would only be needed (if then) if the wall is stone veneer. Wouldn't make sense for solid stone (through to what?).

   i am pretty sure that through the wall flashing is necessary to assure that any moisture that gets behind the wall does not end up in the bedroom.  Masonry is not waterproof thus the need for weep holes.   Of course I do not claim to be even close to a mason and may not know my rear from a rock in this regard.

   It seems both have a role to play in this.  It seems reasonable that he roofer's part is after the masonry though and no flashing that he is responsible for should be installed prior to masonry.  It seems the mason should install the through wall flashing during his installation and the roofing contractor should tie into his work.  I need to talk to my mason it seems.....

   Should be done like a chimney. Best if the mason installs the top pieces of flashing (forget the specific term) and then the roofer does the step flashing. If the mason doesn't do it, someone has to use a masonry saw to cut slots in the wall to install the flashing.

   I just reread your post.

   You say neither claim the flashing?

   You may need to find some new subs.

   As others have said, you need the mason & roofer to work together on this area where you need through flashing. Since you're applying stone veneer, you need your counter flashing to extend from the exterior side of the stone all the way back to the side wall. If you do not through flash and the cap leaks or any water penetrates behind the veneer you will have a leak that will travel down the wall until it hits something and causes a leak problem.

   One this counterflashing is installed, the roofer can install the step flashing under the counterflashing and it should be water tight.

   Thanks to all for the info.  I have an idea of what needs to be done at this point and at least know what I am looking for.
