I would go through the ceiling. depending on the length of the run to the gable end of the house is the determining factor. Any more than 15 feet I would go through the roof. It would depend on where you live if you could just vent into the attic. Is it used for storage or just empty space?
Here in NY I would never do it due to the heat venting into the attic in the winter. It melts the snow on the roof only to refreeze, this in the end is not good for the integrity of the roof. Moisture can also be an issue when venting in an attic. You also have to take into account building codes, here you must go through the roof or out the side. We can't even vent to the soffit.

Well, in Mississippi we don't really get snow. If we do, it's never there for more than a day or two.

Depending on which spare room I use, and the placement of the vent, it could be shorter distance to the gable than the roof. One room shares a wall with the gable. In fact, that would be the best room anyway.

We store some Christmas and Halloween decor in the attic, though on the opposite end of the house as this room would be.

Humidity is high in general here.

The roof is less than a year old, and I'd like to keep it in good shape.

What kind of fan would I want for an 11x12 room? Quieter would be nice, but also with more than adequate ventalation in case a group is here playing poker or something.

That's for the advice. Really good stuff.

Well then you definitely have no worries about freeze/thaw. If going with the room closest to the end of the house, I would mount an external fan on the side of the house, with it going through the outside wall of the attic. Then run flex duct to your inlet in the room. These can be purchased many places, check out Grainger.com or just google exhaust fans.
Many sites will have a calculator to see what your needs are, (cubic feet of room) By mounting the fan outside you eliminate the fan noise in the room. Just remember the key is to have enough free air flowing in the room to displace the air being moved out. This can be as simple as a cracked door or window or installing a vent to the outside for fresh air. Really not a hard project for someone who knows how to use a few basic tools. Wiring it may take an electrician which I would recommend if your not absolutely sure of it.

Thanks, this will really help.- I'm confident in all of my ability to install all of this except the wiring- I can replace a ceiling fan, outlet or switch, but I've never run a new line... I'll get help with that part just in case.

Would a vent straight from the ceiling be enough to replace the air going out through the exhaust? I'd rather not let just outside air in considering how cold it can be (or hot, if summer).

Silly question, but is there a type of paint that would be better at not holding odor? The floor is tile so no carpet to worry about. I assume leather would be best for the chairs?

Don't know of a paint that would do that but by using something that is washable, you know you can use a damp sponge or cloth to wipe it down should suffice.
I would not put the inlet on the ceiling, you need a good crossflow of air. you could just put a couple thruwall vents from the hallway or another room through to do this. It will be drawing air through so no need to worry about smoke into that area of the house.

Great, thanks again! I think I've got a good game plan now.

I'm converting a spare bedroom into a man cave/lounge. Can someone point me in the right direction on ventilation? I have brick exterior so I'll either have to vent through a window (slide up and down kind) or into the attic. I'm not cutting into the brick. If I vent into the attic, should I just let it vent directly into the attic or pipe it out all the way to the gable, or even up through the roof? The roof itself has the vinyl soffit vents, gable vents and a ridge vent, if that makes any difference.

I got 2, 8" inline duct fans and installed them in the attic solidly on a rafter and then ran duct work to them, then made the exhaust go to the soffit on the back of the house. The fans I got flow 325cfm, although there are more expensive ones that flow more air... The ones I got were only 80.00 per fan, and the flexible metal ducting was 6.00 for a 10ft section. You need to make sure that there is an air supply that is large enough to supply the fans, or the airflow is restricted.

You can count on my two cents... I will definatly take your invite and tell you all how it works after it gets installed; which will be before winter, and then I'll have the chance to see how it does.

Can't wait to hear the report. I tried the purifier route (about $150 for the unit) with activated carbon filter and that was garbage. The only true way to get it done is exhaust the air. I am currently man caving in my garage and I am looking for a more comfortable solution that the Mrs would be happy with, or at least tolerate.](*,)

Just looked it up at Soler and Palau and found out that these avg about 12 Sones WOW! Crank up the sound!

$280 isn't bad, just saw the 360+ CFM model fo ~$250 on VentingDirect.com

I did a test run last night with the ceiling fan on and an old window dual fan that blows out. It was never "foggy" but the room has a very strong cigar odor that lingers and stretches out into the hallway. I have an air purifier running as well but does not seem to do enough to clear it out. Would one or two exhaust fans really provide enough of a difference to prevent an odor?

Purifiers are definitely a haggle. I have spent a fortune on them. I bought all my stuff at VentingDirect.Com and yes you have to be weary of the noise factor of these fans. Mine is a little better now that I have a speed control on and can run it at a lower speed. The trick is to get it as far away from the intake as you can. Mine is straight through at about waist level on the inside wall. I does a good job keeping the room exhausted though. If you were to RELY on a low noise set up, you would have to plan it out more sacredly to achieve such a thing. Like distance and maybe another of the closed inline models that mount inside a duct. Our house is so old that the simplest was the only..est way to do it. If you got a smaller one of these it wouldn't be as noisy,,true...but with the SWF200 and a speed switch, it's like having them all on demand for when ever or what ever you may want do. (a little self generated moral support after I heard how loud it was)... I watches some vids last night on my pc from the comfee chair and the fan on a lower speed and wasn't bothered by the noise, lack of exhaust, and I could hear the speakers across the room. HURRAHAAA

p.s. you also have to be careful with under the doors. That's a sure and easy path. I used a towel rolled up to block the bottom of the door and then my Mom bought me a really neat roll for doorway drafts made just for that.
