Roof or skylight leaking?

Trying to determine if the roof (e.g. flashing) or skylight is leaking.
Are there some signs that point me in one or the other direction?

Yes, the skylight or roof are leaking. They are one in the same. You have to get up there and see what's the problem. Usually it's the skylight or flashing for the skylight.

Observe it when its raining and look to see if its coming from the glass edges. Or take the interior jamb off and see if its coming in from the outside edge of the unit. If it is, its likely the counterflashing kit or lack thereof. Of course if you are missing any shingles that would be an obvious leak.

Or try to recreate the leak with a garden hose.

I probably have to put there a permanent ladder to observe.
But I don't think it is a large leak, I don't see anything when it is raining. Granted, it can come in slowly.

My association sent out a roofer a while back for another leak. I asked him to quickly look at it. He told me that he thinks it is the flashing. But after a call to the office it converted to a defect skylight... The skylight is from 2000 when the house was built.

Is there also the possibility that being simply condensation water in the winter?

Some more picture of both skylights. What concerns me most is the water spot at the bottom of the right skylight where the drywall edge joins the ceiling. Does this help to diagnose?

You keep posting pictures of the inside which are pretty much useless, need pictures of the outside on the roof around the skylight.
Even then it may not tell us much.
How old is it?
95% of the time when a skylight leaks it's not the fault of the window, it because it was the wrong window or was installed wrong.

House was built in 2000. So, the skylight must be roughly 17 years old. South exposure in Chicagoland. I am assuming it is a Pella, since all other windows are Pella. However, I do not know.

The skylights are on a 3 story townhouse. Getting up there isn't that easy. Here are some pictures from the roof from a window.

If the wall is damp/wet this time of year then it's likely a leak and not condensation. Someone has to get up on the roof and inspect the skylight and it's flashing.
