Question DetailsAsked on 9/12/2012

Water leaking onto stove from overhead exhaust fan during rains.

We had some water leaking onto the kitchen stove from the exhaust fan above it during the last couple of heavy rains. During the last storm it even started leaking through the ceiling light which is about 4 feet away from the exhaust fan on the ceiling.

This is no fancy over the stove exhaust system just a round circular fan that sits flush up against the ceiling and vents to the roof. I can't get up to the roof to see what it looks like from up there due to a recent injury but I'm guessing that maybe the flap isn't closing properly. I thought that maybe it was the seal around the the exhaust on the roof but I don't see any water in the attic behind the walls so I'm assuming the water is just coming in down the vent and some is leaking onto the stove. Does that sound about right?

Can't fix this myself. I'm wondering who fixes this kind of thing. Would it be a roofer or an appliance guy? If you say HVAC, we just had furnace replaced, should I call them? Thanks

Sounds like the leak is where the exhaust pipe penatrates the roof. Could b the "cap" or at the "flashing" at the roof. A roofer would be a sure bet to repair/replace whatever it is. A handyman could likely replace the cap,be sure to ask before having one come out.

A qualified roofer should be able to remedy the situation no matter what is causing this water intrusion.
Can't say the same for the handyman or AC guy.

Only 5 likely sources that I see (in no particular order), all of which call for a roofer:

1) a leak through the shingles uproof from the kitchen vent, and the water is running down either on the top of the tarpaper (roofing felt), or under it, and going down through the kitchen vent hole, if it is roughly directly downhill of the leak spot - which could be a roof leak or another vent/chimney uphill of it letting water in. Could also be same type of leak, running down the underside of the sheathing (it will do this on about 4:12 and steeper roofs) until it hits the first thing that blocks it - the kitchen vent duct, and runs down it.

2) leak in the flashing or caulking around the roof vent hood

3) rusted through roof vent hood, letting water in

4) a random roof leak, which just happens to start dripping down in that location

5) Could possibly be stuck flapper if the rains were real hard or blowing toward the flapper, and splash from rain hitting the exposed skirt of the vent splashed into the vent, then down along or into the duct.
