  • new exhaust fan in restroom

    House walls does not have space between ceiling and roof, therefore no space for exhaust fan duct to be connected through the wall. Can anyone suggest me how/where to connect exhaust outside. I don't think leaving it in attic is a good idea.

    Should be able to get a roof vent. It installs through the roof and has a rather large flashing to fasten and put underneath the roof shingles. Use a aluminum 4 inch duct hose

      if there is an outside wall in the bathroom you can install a wall mounted exhaust fan and exhaust it out through the wall in the same manner as a laundry dryer vent.

      You could also run it straight up and out through the roof with a flashing and a riser in the same manner as the plumbing vent. If you run it up and out through the roof you should consider installing a mushroom cap on top of the pipe to keep rain or leaves and debris out.

      If you have a raised foundation or a basement you could consider running it down below the floor and out to the nearest exterior wall, again terminating with a laundry dryer vent.

        There also is a down vent with fliper in it that goes in the overhang so you dont have to go up through the roof. Dont vent it just in the attic

        My mistakes dont define me they inform me.
