Sealant around roof vents

During my spring dewinterize, I was checking the roof sealants around the vents. On the bathroom vent sealant I found a small hole (about 2 -3 cm long) near the outer edge, away from the fan housing. It has rained a couple of times since then, and I have not noticed any leakage, but I know it needs to be patched.

What type of sealant is installed from the factory around the fan housings? Is it a Dicor sealant? If not, what is it? Could I use a regular outdoor caulking to patch the hole? Or does it need to be specialized?

Sorry for all the questions.

Thanks.
