We have a leak around our bathroom vent, not everytime it rains, but frequently enough to be of concern. We have had the roof replaced about 12 years ago with a reputable company.
Where should we start to get the problem resolved?
If it is leaking only when it rains. Then I would start with the vent outside the house, either it's on the roof or on an exterior wall. That's the most likely cause, either it's broken or the seal (caulking) has failed.
First, your pipe (venting) is not insulated causing condensation. Also, we normally extend the piping so as any minimal condensation has enough time to dissipate preventing any damage from occurring by the time it reaches the interior fan area.
I hope this helps you!
