I have a turbine type ventilator installed on the roof. It was

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?


I suggest getting rid of that thing when you can. Until then they make
covers for them or you can try some heavy duty plastic very well secured.

Proper passive venting is a much better solution in almost all
situations.
