Light showing through fan vent

I am currently in thr middle of having a new tile roof put on. Everything is done except the laying of tile. There are also 2 solar attic fans installed. I wanted to see how they were working and I noticed that I could see light coming in from an exhaust vent {bathroom fan). The salesman says this is normal. There is no ridge vent now because of the attic fans

Post a pic but I doubt its anything to worry about.

That looks,based off your picture, to be correct. You will see some light coming through a rooftop power fan. Of course, go up while it’s raining and see if it’s leaking just to verify.
