Agree completely with the responses on the difference between frequency bands and modulation types - it's the frequency which determines the propogation of the wave. The question was asking about FM signals in the VHF band, as used by commercial radio stations.
Back to the original question of VHF (not FM) propogation, though... I'd be surprised if reflection is really very significant, although I don't have any numbers to back this up. If VHF waves were reflected off buildings, radio reception (FM radio and aviation comms) would be full of echoes as we pick up a whole load of reflections off any buildings in the vicinity.
Does anyone actually have any numbers on attenuation of VHF signals, both reflected off of common materials such as buildings, and passing through these materials?
