The Proper Way to Vent a Bathroom Fan

New NuTone vent fan

Gary wants to add a new vent fan into a bathroom.  The contractor he’s working with seems to be suggesting venting to the attic.  He’s not sure if that is the best option.

Gary is absolutely right to question this contractor.  Without a doubt, a vent should never exhaust hot, moist air into the attic.

The job isn’t done until it’s properly vented through the roof.

Providing proper ventilation in your attic is important in both summer and winter since it will:

      • Keep your attic cooler in the summer, which can lower your air conditioner bills and make your roof last longer.
      • Reduce condensation during the winter, which can lead to mold, mildew, or rot.
      • Use this calculator to determine the cubic feet per minute of air your fan needs to move to be effective in your bathroom.
