Two Towers quarantine roof glitch

[Johns]

hello, i was in game & i saw a guy on that was glitching on the roof, not sure how he got there & was wondering if any1 knew how to do it. i searched for it here in glitch section but culdnt find the one i saw. well, here is the descriptin of the glitch;

its on the two towers quarantine map, there is a hole on the roof across from the yellow crane thing, at the hole, there is a wooden beam that sticks out a littl, & thats where the guy was glitching, he was able to get thru the section of the roof & was able to stand on the beam, it kinda looked like he was floating but he wasnt. its a cool spot since the zombies cant attack u while u are there & you can shoot at them to stop them from trying. what i wanna kno is if this is a glitch or do i just use fly hack to get to the place? sorry if my description doesnt give much info, i would add screen shots of the spot where the glitch is but i dont know how to add screen shots :P

thanks for ur help every one! /yea

dude this is such an easy spot to get to just go up to roof near hole and go down near the left side of it from the top (where the bigger side of the hole is) drop down and walk on the beam works all the time for me
