Exhaust Vent Defects found during Home Inspections
These are bathroom exhaust vents that are exhausting to the attic. This is common for houses from 60’s to 90’s. These vents should be routed to the exterior via a roof vent. This will prevent the exhaust vent from expelling hot moist air into the attic, which can lead to condensation and mildew buildup. Recommend repair.
This is a kitchen exhaust vent. The vent material is flexible rigid material, this is improper material. This kind of material is conducive for catching grease buildup and becoming a possible fire hazard. The ductwork for the exhaust system needs to be smooth and have as few bends as possible and should be made from galvanized steel, copper or stainless steel. The ducts need to be mechanically fastened and sealed with tape or mastic. If tape is used, it should be metal-backed and not conventional cloth-backed duct tape, which can dry out and crumble.
This is a bathroom exhaust vent. This is improper material. The one in the picture is for dryer exhaust from appliance to the wall connection. It’s made of foil paper and can easily be damaged in the attic, creating unwanted hot moist air expelling to the attic.

Check this one out, this is my favorite. It’s the kitchen and bathroom exhaust vents venting into the main sewer plumbing vent. This is a possible safety hazard. Sewer gases are flammable and the exhaust vent could be a source of ignition. Recommend repair by licensed contractor.
