Upon inspection of the upper ballast roof, we found several areas with bad patching and some evidence of leaks around HVAC penetrations and the drain system. We intend to remove and replace the membrane around the drain where the insulation is saturated, repair the patches in that area and the surrounding area on the parapet walls, and detail the HVAC ductwork with a termination bar.

In this photo, you can see that this recent patch is loose at the edge and I can see right into the underside of the membrane.
