BATHROOM EXHAUST FANS
Your bathroom exhaust fan helps to keep your bathroom fresh, and more importantly, it removes moisture vapors generated from bathing and other activities. This prevents condensation on walls and fixtures. Without proper exhaust, moisture condensation can do serious damage to drywall, wallpaper, window coverings, and cabinetry in your bathroom. It may also lead to serious mold issues.
Your clothing dryer removes moisture from your laundry and exhausts the moisture vapor out through a duct in order to prevent moisture problems in your laundry room, much the same as your bathroom exhaust fan does in the bathroom.
A FREQUENT PROBLEM
Most homeowners believe their bath fans and dryer ducts exhaust to the outside. Far too often, this is not the case. We regularly find bath fans and dryers exhausting up into the attic, releasing moisture from bathing and laundry that regularly collects on attic surfaces leading to mold issues and structural damage.

STRUCTURAL DAMAGE IN THE ATTIC
Moisture left unaddressed, can lead to the deterioration of wood structures that support your roof and the frame of your home. The moisture weakens the wood by slowly destroying individual wood fibers, layer by layer.
Attic moisture can also destroy or retard the performance of your attic insulation. Insulation loses its insulating capacity when wet. When your insulation is not doing its job, you pay for it in utility costs all year round.
MOLD LOVES MOISTURE
Mold thrives in moist environments and can expand rapidly. Once mold colonies expand in your attic, spores easily pass down to living spaces. For occupants suffering from allergies, asthma, or other breathing disorders mold can lead to serious health problems. There are dozens of mold species, some more dangerous than others. It is near impossible to determine a mold species by the naked eye. If you have mold in your attic, have it removed professionally to ensure thorough eradication. Learn more about attic mold here>
SIGNS OF TROUBLE
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 moisture. Correcting problems at this stage could be very expensive.
Have all of your bath exhaust fans and the dryer exhaust checked! Both should be connected to a sealed and insulated duct that routes the moisture outside. The duct should be connected to a dampered roof cap that prevents the moisture from reentry.
