DESIGNED TO REMOVE MOISTURE
Your bath fan and dryer exhaust are designed to prevent moisture problems in your bathroom and laundry room, respectively.
WHERE DOES THE MOISTURE GO?
Well that really depends. Most homeowners believe their bath fans and dryer ducts exhaust to the outside. But that is not always the case. We often find them exhausting up into the attic.
When bath fans and dryers exhaust into the attic the moisture they pull away is then released in to the attic where it will build up on your attic sheathing.
ATTIC MOISTURE = COSTLY DAMAGE
At first attic moisture and condensation will lead to mold on hard surfaces like your roof sheathing, but over time if left unaddressed, the moisture will rot the wood rendering your roof and connected structures unstable.
SIGNS OF MOISTURE
If you are seeing dark stains on wood surfaces, you likely have mold developing. If the wood is soft and flaking, it is deteriorating from the moisture. Correcting problems at this stage could be very expensive.
Have all of your bath fans and dryer exhaust checked! Both should be connected to duct that routes the moisture outside. The duct should be connected to a dampered roof cap that prevents the moisture from reentry.
