Same with mine. I actually just removed the back one the other day and found out it was leaking from a broken screw. Not to mention there was little to no sealant surrounding it.
Put 20ga sheet metal sealant and screwed it down, no leaks after a storm passed through the next day.
Was trying to find a pic of it but not able to see FB @ work.
