First I'd just make sure of the local regulations for charging employees for mistakes. Almost every case I've seen where a tech brings it before labor board the dealership loses because you normally can't just make the rule for the techs. I mean what is worse, a tech putting a screw through the roof or a parts manager accidentally ordering a $2,000 non-returnable part that will be in inventory for the next five years. Everyone makes mistakes and if you have a policy of people paying for it then it needs to be uniform SAs, porters, techs, everyone.
Second, how hard is it to find techs in your area? My guts always tells me that this is more of a thing to fire someone over, not recover the costs. Use standard written notice policies for your shop and then just them go after three or four problems. (My policy was if the damage cost the shop more than $100 then it was a write-up - not including the tech's donated time if he could right the wrong.) I could also use the write-ups to deny raises or merit promotions.
Last, I always tried to consider the infraction on its own. Like your example, every tech in the world knows you have to be extremely careful around headliners and the roof, so what caused this mistake. Did he mix up the screw lengths and put the wrong one in? Then that's careless, dismissible behavior. If there really was something that was unusually tricky about the installation then maybe Id be more understanding.
In the end, I try to remember that this is a dangerous profession and environment. If someone is careless then how long before they are cutting off an exhaust pipe with a torch and hack right into the gas tank. I only had to fire a tech once for being overly careless and looking back I believe cross-thread Jack as he was known in town, could have messed up a junk yard. Even though hed been turning wrenches for 18 years he was suited for the job.
