I've closed in a garage and am about to have it bricked in using the original brick. In the image below, you can see that there is an opening in the soffit. I think this is to allow the wall to breath into the attic (i.e., weep holes at bottom, vent at top)?
At any rate, the garage doesn't have it where the G door was (and much of that area is taken up by a large window (grey flashing and rightward). I seriously doubt that the 20' south-facing wall does either (previous owner closed it in and bricked it to make a garage when it was a car port).
So, given that I won't be able to recreate the vent, how important is it that the wall space between the brick and sheathing be vented (very, I think...)? Would creating additional "weep holes" at the top near the soffit work? If not, what is the best way to handle this, short of tearing down the existing brick wall?
I live in the deep south in a hot humid climate (6-8 mos out of the year).
