What is the proper way to fix my leaking skylights?

I went up and replaced all the screws with new screws which have an EDMP washer with the clutch on my drill low. It was getting dark so I'm sure some got slightly overtightened but it reduced the amount of skylights leaking from six to three. The ones that are still leaking were leaking at the same spot prior to the screw swap out.

I'm very tempted to just pull the screws on the ones that still leak, shoot silicone into the existing holes, put a screw back in and goop silicone on the top but that's just going to leak again eventually. Two of them are over the insulated side of our shop as so I'd like to have a real solution. I'm not opposed to removing the sky lights if they are going to keep leaking but they are nice during the day.

I will add that many of the existing screw holes did not appear to be predrilled so that could have been tearing the washer. My only thing to discredit that is then I would expect there to be more leaks throughout.

Short story long I just want to get it taken care the right away opposed to everything else we find from the previous owner. Thanks in advance.
