My Bathroom Fan Has Water Leaking Through It, Why? - February 27th 2007
Q. Help! Our newly installed bathroom exhaust fan leaked for the first time since it was installed in the fall. I think It is due to the warm weather melting the snow on our roof. When the warm air from the fan melted the snow around the exhaust, it froze at night to ice and when the temperature went down melting the ice it found its way into the house. Any tips??
A. It sounds like your problem is caused by your exhaust duct terminating at the roof under a roof vent only to build up ice when it's cold and leak back when it melts; a common scenario to cut corners. Your vent pipe should terminate up too and out of a roof JACK commonly known as a GOOSE NECK VENT.
