When bathroom fans are installed during a renovation or retrofit, MAKE SURE they are vented to the outside.
Why it matters: When fans vent into to the attic, moist air and water vapor drive up humidity levels.
🥊 Reality check: We just re-roofed a house that had 5 fans (4 bathroom, 1 laundry room) pumping humid air into the attic.
- The vent hood over the gas range was venting to the attic as well.
💡 We addressed these issues during the re-roof.

✅ For your Smart Homeowner list
- Try to account for all your bathroom fans and see if you have vents like this on your roof.
