Roof-level leakage

Our firm did the masonry work for a new school. Ever since the building was completed, there has been a leak just below the point where the school roof intersects the gymnasium wall. The roofer claims the roof is not the source of the leak. The architect thought the leak was occurring because we forgot to put weep holes in this area. However, we feel the real cause was the architect's requiring us to hold the flashing back 1/2 inch from the face of the wall. We agreed to install weep holes in the masonry to see if it would help, and did so by removing brick units and replacing them with an open head joint on one side. Before reinstalling the brick, we inspected the flashing to make sure it was not damaged. We found that in all cases the flashing was held back no farther than 1/2 inch from the face of the wall. Yet after the repairs, the leaks were worse than they were before. What should we do? More
