buy a fish tape, that thing we electricians use to pull wire

push it in the hollow from the bottom and see how far you can extend it

if it goes all the way and bumps up against the roof, you are good

it it only goes part way and stops, then you know to find another way

the thing is very handy tool to have around and NOT expensive

Plus if there are any light switches, lights, etc on the inside wall pull them and use the hole for probing.

I use a 1/8" flexible fiberglass wire puller that also serves me well for probing. I also have a 4' long flexible drill bit that has served me well. No exposed wires covered or not for me.
