Q54. I have found some conflicting information for the roofing scope and would like to have some clarifications. New roof assembly shown on sheet A1.22 shows that we are to leave the existing base layer of insulation in place and install a new system on top of it. Keynote 1 on the same sheet solidifies that. Keynote 1 on sheet A2.40 states that we are to remove all roofing down to metal deck, paint deck, and then install a new roofing system. Can you please confirm which method we are to use.
