Best I can come up is below from the Brick Industry Association. He's got two elements right. There's brick and there are shingles. I couldn't get into the knee wall attic area to see if the rafters were tripled. The other stuff, that should be visible, isn't. =============== There are several locations where the brick meets the roof shingles. There is no visible step or counter or through wall flashing where the brick meets the shingles of the roof. There are no weep holes at the base of the brick. The junction between the shingles and the brick is covered with mortar. The seller/builder says that "through wall flashing" was installed, then step flashing installed with the shingles and then the brick was applied. Through wall flashing is supposed to go "through" the wall and be visible on the outside, with weep holes above the counter flashing over the step flashing. See diagram from the Brick Industry Association regarding this type of junction between brick and roof. (Picture 2) I couldn't get into the attic section under any of these areas to see what framing was done to support the brick but tripled rafters are the norm. In addition, there is no kickout flashing at the bottom of the roof slope to force water into the gutters. (Picture 3) Water that doesn't get "kicked" into the gutter runs down the wall and can penetrate behind the brick. Question 1: Where does the water go that gets behind the brick in the form of vapor. I don't see a way for it to get out of the wall. Question 2: When it comes time to replace the shingles, and that time will come, how is your roofer going to get the shingles out from under the brick and new shingles and step flashing UNDER the brick? This is a problem with no easy solution. Consult a brick mason and roofer and follow their advice. Be aware it might be costly.

The buyer is a mechanical engineer with a good handle of knowledge. I won't go into how the deck is attached to the brick veneer with tapcons.
