what does it come with or is it just the led bar? how long does it last?

Is there supposed to be a high pitch buzz noise ?
Doesn't make any noise, check your connections. you might be getting AC ripple from a defective diode in your alternator.
When the vehicle is not operating, does this drain the battery since its connected to the battery?
No if switch is off it has no draw on battery.
Will this mount on a car roof or just meant for bumper？
It should mount almost anywhere if you have the tools, ability, and time to place it.
If you do roof, you may need a horizontal roof rack going over driver and passenger area and then bolt it to that.
If it's bolted to body, you'll need: large diameter SS washers(x4), interior lining out/rolled up and dril holes and put silicone on bolt/washers for leak prevention, possibly new bolts or cut the stock bolts to make them shorter so when place lining back they won't poke out.

Metal. Nicely machined and good quality

if you buy the one that includes the wiring harness then yes there is an on/off.
