Every time that it rains heavily here in southern california (which is not very often), I get a slow drip of water coming out of the ceiling heater/fan in the bathroom. When it is windy it drips more heavily, but even when there is no wind I still get the leak.
I crawled up on the asphalt shingle roof to make sure that the vent pipe was properly flashed (vent is new, so the roof jack was recently retrofitted), and it appeard that everything was sealed properly. Just in case I put a generous amount of Henry’s around the vent pipe, and carefully renailed the shingles around the area that appeared to be lifting up a bit.
The next heavy rain came, and the leak was still dripping, so I looked into the crawlspace above the bathroom ceiling. I saw a wet spot right next to where the vent pipe went through the roof.
Anyone have any suggestions about how to stop this leak?
Thanks,
joe

You are describing a vent 'pipe' and a jack flashing.
Maybe just bad terminology but the proper exit for this would be a flapper vent cap made for roofs. That way no open pipe is facing up into the rain. The openning faces downhill and only opens the flapper when the fan is running.
Excellence is its own reward!
the water is leaking in outside the vent pipe (which has a cap on it); that is, the leak is occuring somewhere between the exterior of the vent pipe, and the roofing.
This is a 4/12 roof and there is a roof jack with the flashing portion tucked underneath the roof shingles.
Did you use too much sealant?
I realized that too much or in the wrong place will trap the water and force it back under the shingles.
