Bathroom fan venting

[cduphily]

yes it's "legal" (not much is "illegal" in this basackwards state) but I still don't like this as general practices go. To great a probability of adding moisture/elevated humidity levels to the attic space. (imho) Never mind the fact that getting a builder to install gutters is like pulling teeth.

What say you?

You guys are on a run today! What is with all this "code" and "legal" stuff?

At least they vented it to the outside!
If I got $1 for every un-vented vent I come across....

I agree with David. It would have been nice if they had skipped the vented piece of soffit in the immediate area to reduce the risk of running the vented air right back up into the attic----but at least it isn't venting to the back side of the soffit like the two I had yesterday </IMG>

Attached is what I find aboout 33% of the time. Exhaust in the attic under the insulation.

The other is where the exhaust blows on the sheathing.

Would take an additional 15 minutes and $10.00 to do it right when being built.

Chris,

I see these on an everyday basis and have never run into moisture issues in the attic at that location. They are absolutely fine. I just make sure they are connected.

I always enjoy the "duck tape to the nail" installation method.

William,
Was the second photo taken in a townhome?

I'm kind of curious to see where this thread goes, I've been asked to vent 2 bathrooms in a reno and the only place available is either through the roof or through the soffit. I'm looking at both the pro's and con's.

There's nothing wrong with venting your bathroom fans into the soffit area.

A roof penetration would be susceptible to leaks.

Thanks David. Those were my thoughts as well. I just put a new roof on this one last year and I just dont like going through a roof for venting a fan.
I inspected a house 2 years ago that had all 3 bath fan vents connected to the main stink-pipe. Had another where 2 were ducted to the roof vents.

Use the soffit with pre-made louvered covers. They're fine.

Thanks David. That's what the owner bought.

Or do you mean down through the soffit using an outlet designed for under the soffit venting? I endorse this but not into the soffit/eave interior. "Into the soffit" has not been allowed up here for the last 2 code cycles, I believe.

I'm not afraid to vent through the roof. Just know how to seal it well. I installed a great roof vent manufacturered by Broan last fall......a bit expensive but if you want quality, be prepared to pay for it. I tell clients now that if they want a decent bath fan system,(powerful, quiet, controlled by a timer on a circuit different from the bath lights,and vented to the outside) be prepared to pay at least $325-$350 upwards +taxes.
