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.
Leaks at roof drain, bad patchwork and no termination bar at HVAC penetrations
