leak from exhaust pipe

I got my water heater replaced. It uses gas and has exhaust pipe exiting thru the roof.
Now when it rains, there is very small drops of water leaking from the exhaust pipe.
what is the best way to fix this? I had a guy come out a couple of months again and he got on the roof and put some sealant.
But it is still leaking.
I wonder if it's more involved than just putting on sealant.

Does the vent pipe have a cap on top? Is the water you see on the inside or the outside of the pipe?

If it's running down and dripping off the inside of the pipe, then it's likely from rain entering the inside of the pipe or possibly leaking in at a joint in the pipe. If it's on the outside of the vent pipe then likely the boot sealing the pipe to the roof needs repair or replacement.

thanks for your reply.
when it leaks, I observed. It's very small drip coming out of nowhere. It almost coming out of the pipe.

It happens my AC/heating unit exhaust pipes also have tiny leak issue. they were all replaced last year. I guess the contrators didn't do a good job and moved the pipe a bit and made it loose.

does this fall into roof repair or plumbing?

Does the hot water heater share the flue with the boiler or furnace? Also, need to know the answers to gunguy's questions.
