I know that the Secret Service doesn’t have infinite manpower and that they often fill this gap by coordinating with local agencies to cover things. That said, when such coordination happens, they should be the management and people in charge. I’m willing to believe that it was local PD’s responsibility to have a person on the roof, but I imagine it was also the Secret Service’s responsibility to double check that that was happening.
Literally on the roof or figuratively on the roof, it's the same deal: maybe that was the PD's responsibility and maybe it wasn't, but either way the Secret Service presumably has responsibility somewhere up the chain to make sure it's being done.

The SS may not have wanted anyone on the roof, especially if they had a firearm
