When you do something that significant in structural terms, you may have to bring the whole structure up to current code standards. Is the existing roof structure shot? Why not re-roof it, and install several inches of sloping insulation to improve the drainage? Of course, you have to evaluate the roof drainage system, be it roof drains, scuppers, or whatever, and incorporate that into the re-roofing job. What drainage system exists now? Nice pictures, but you’re still keeping all the important roof and wall details secret. What is the existing roof structure, its connections to the wall, and the wall construction details? When you put A.Bs. in at 4' o/c what are you actually grouting them into, at the conc. blk. and at the brick? Is there a top bond beam, can you grout down several courses, etc.? Or, will any roof uplift just lift a single conc. blk. out of the wall with your new A.B.?
