The first step is to head to the attic.

Attic insulation around bathroom exhaust fan.

I recently installed a bathroom exhaust fan. I used flexible 4 aluminum duct to the exhaust damper on the roof. The job of a bathroom exhaust fan is to remove moist air and foul odors from the bathroom. Inspect the attic floor around the fan box for air leaks.

T he result of the insulation problem around a bathroom exhaust fan is either water stains or mold near the vent of your bathroom. In existing homes air seal and insulate around new or existing bathroom and kitchen exhaust fans to minimize air leakage to and from unconditioned attics. In un conditioned space such as an attic where otherwise your fan duct will be exposed to cold attic air in winter use insulated solid metal ducting or insulated flex duct. If bath fan ducting isn t properly insulated the moist air from your house will condense inside the duct.

I have a bathroom exhaust fan that is vented directly into the attic. Remove insulation around the exhaust fan on the attic side. This is non usable space and it is well ventilated with ridge and soffit ventilation so it does get cold in the winter. It has started to leak water back through the exhaust fan into the bathroom.

What is the best thing to do to correct this problem. Insulation problems will lead to other problems like the fan not being able to extract any humidity from the bathroom at all. The duct runs in my attic above the bathroom ceiling two story home. If you take it through the roof using a metal pipe do you use insulation around the pipe.

Water stains on the ceiling around your bath fan may indicate a leak coming from the vent cap on your roof but condensation is the more likely culprit. When moist air is carried through a duct that passes through a cold attic space condensation will occur. Home bathroom bathroom exhaust fan.
