Leaks can be difficult to properly repair. The first thing you will want to do is verify as precisely as possible where the leak is. Best to run a hose on the roof so water flows over suspect seams while looking from the inside with all interior and insulaion out of the way with GOOD light (and a cold beer). Once you are sure it is entering the vent seal(and not a cracked lid) I would remove the screws (or rivits) from the vents and remove them. Clean the non hardening adhesive sealant from the roof and the vents and install fresh ribbon caulk between roof and vent. You will probably see where the water has snuck in after removal. Autobody supply or some auto part stores carry it in a roll. It is used to seal bolt in automotive glass as well as taillights. If screws are used to re-secure the vent, a little butyl around the screw prior to insertion will seal the hole. If you are using non closed end rivits, some oil based siding and window caulk in the mandrel hole or even ov
er the whole rivit head(nobody will see it anyway if you use matching color). The vents are really inexpensive to replace but if the hole pattern is different you have just added more potential entry points by re-drilling. When I pulled mine there was already two sets of holes
