how big of an antenna? A small "hockey puck" or a big choke ring?


What's the roof surface?

that works. There's quite a few fairly large antennas on flat roofed 
buildings where there's a kind of metal "tripod" weighted down with 
bricks or cinder blocks. If you look for what are called "no penetration 
antenna supports" you'll get lots of hits.

I've used silicone caulk to "glue" a bracket to a roof tile (concrete 
tile roof).
