I have used hanger bolts on this exact roof several times. Filled the holes with copious amounts of a good polyurethene sealant (vulkem) before driving the hanger bolt, then built up with sealant around the hanger bolt base. Haven't had any leaks, always tried to stay on the ribs, above the water line.
