Bathroom Fan, or not?


Coincidentally, this OP has just contacted my office to have two separate Broan Vents installed on his roof section sometime mid next week.

Good advice from everyone else so far too.

I lost touch with Ed and have had little luck finding someone else to do this. I looked into some handymen but they want to run the vents out of the soffet. I don't think that is the best option. Could I install vents on the roof myself? I'm really nervous about it.

IMHO I would NOT reduce to 4" then connect the 3". Stay at 6" thru the roof, "T" in and reduce to the other sizes, Also be sure u place a damper in line besides the little ones in the units.

OK I'll remember that but how do I install a vent in the roof?

Pick a spot easy to work in, remember to keep it visually below the peak, this keeps it from being seen from street if that is important, be sure to work in CENTER of a bay, mark the center punch a big nail thru. Now go to roof,carefully un nail and peel back shingles, IF possible roll back the top paper, cut the required hole, slip the roof hood under the top sheet, keep it over the lower paper, nail it home, re shingle. Now go back into the attic, make all your connections. Simple

Now if all this sounds a tad daunting :}:}:} CALL ED AND GET HIS BUTT OVER THERE

Finally, I did it myself! It wasn't so bad. Of course it hasn't rained yet...
I think I did OK though. Picture #2 looks a bit funny at the top because I hade to jerry rig the top adapter. I think it will work fine though. #2 is a half bath so there isn't much moisture anyway.

Glad you pointed out that the OP should make certain that the fan is venting to the outside. Because I found on some service jobs, that the --bathroom exhaust fan-- was venting into the attic. In some cases due to the section of flex pipe being disconnected and in others it was never connected to the outside. (No matter what) Don't Drink and Drive, Ever!!!

Why does there need to be a space for air to enter the room? My wife thinks it is sucking the heat out so she closes the register and puts a towel under the door.

It is sucking some heat out of the house and along with it super moist air (or bad odors) created in the bathroom. If air did not enter the room, air would not leave the room once you created enough vacuum to overcome the power of the fan. Chances are you will not be able to create a tight enough seal to overcome the power of the fan with towels and closing the register but it is reducing the efficiency of the fan. You could accomplish the same effect with a little more control and convenience by installing a speed controller for the fan.

The bottom line... You want the moist air out of the house. It causes damage and reduces the efficiency of most insulation. The heat loss is a trade off and not a major cost unless the fan is on for many hours everyday.

Thank you for the excellent explanation. Today we notice that we can now hear outside noise through the fans. It is a bit annoying right now but I still need to insulate the pipes and the fan box. I hope that helps.

I was looking around, I think I'm the only one on my block that vents the bathroom fans outside.

If what you're saying is true, we're in big trouble. (Just kidding). (No matter what)Don't Drink and Drive, Ever!!!

Here are the vents. I'll have to get on the roof to get a better picture. They are facing west.

Regarding insulating this, what do you mean by a "blanket"?

what you want to use is insulation wrap. An insulation blanket is more for an electric water heater.
