Flat roof, 1926 brick construction. I wanted to know if the roof flashing on this parapet wall is correct. It doesn't hang over the edge at all. This is an area where the brick coping tile broke, but the roof overhangs the parapet like this the entire perimeter. Trying to chase down some very slow water penetration that's killing my upstairs plaster in 4 spots, towards the front and back and on both sides of house.
