Many mistakes are made regarding attic ventilation, with almost all of them happening when a house is being built. One of the most common mistakes happens with the installation of bathroom fans. I would guess that over 90% of homes have improperly installed bathroom fans. The problem is not with the fan itself, but with the type of piping that is connected to the top of the fan and where that piping goes.
Understanding How Attic Ventilation Problems Are Connected to Bathroom Fans
The particular example shown in the pictures of an attic ventilation issue is on an 8-year-old home. It shows the damage that a vent pipe which is vented out of the soffit can do. The first photo depicts the problem. The green arrow points to where we found the end of the pipe, which was directly above a soffit vent. The purpose of a soffit vent is to allow outside air into the attic. The yellow line shows that the warm humid air from the bathroom was being pumped to above the soffit vent, then being pushed back into the attic from the outside air entering the vent.
The red circles show the water damage that was caused by the air from the bathroom being pushed back into the attic and condensing on the underside of the roof sheeting, as you see in the second photo. This particular problem was so bad that enough water was formed during the condensation to stain the drywall on the ceiling and was visible on the inside, as you can see in the third photo. The correct way to vent a bathroom fan is to connect flexible insulated piping from the fan directly to a specifically designed roof vent in as direct of route as possible.
