Stop the heat from leaving the attic in the winter,

Which in the snow belt, is exactly the wrong thing to do. Yea, I know
they do it, but you really want that area under the roof to be the same
temperature, or close to it, as outside. In areas with no snow or ice
accumulation, then OK as long as there is adequate ventilation without it.

and stop sideways
rain from entering.

I have a turbine type ventilator installed on the roof. It was
installed several years ago to improve a humidity problem which has
since been resolved.

Within the past year we have noticed a slight leak in the kitchen
pantry exactly beneath the ventilator. Water is evident only a few
time a year and I cannot determine where it is coming from. I
inspected the ventilator but did not see any obvious cracks in the
base. I applied tar around the base in case there was a crack in
the roof near the base, but the problem has not been solved.

The problem appears only certain times like after a heavy rainfall
or snow, but it is not always consistent.
Any ideas?
