ducting bathroom exhaust fan

Hi everyone-

I'm installing a new bathroom exhaust fan and am wondering about the best way to duct it. It's on the front of the house, so I'd like to avoid using a roof vent. I'd like to put a vent into the soffit, but I've got replacement vinyl soffit over the old wood. I couldn't find a grill type vent and access from the attic is really tight. Is there enough ventilation coming through the soffit that I can just run a 4" flexible duct in there and hope it will vent w/o drilling any holes?

Any other ideas?

Thanks!
Rob

Cool

I'm afraid not.
The purpose of a bathroom vent is to exhaust all of the warm, moist air from the home bath interior to the outside.
Venting it into the attic will only create a moisture problem there.
It should be vented through the roof, through a wall, or through a soffit vent.
You might make a homemade vent with screen and hardware cloth over a hole in the soffit to vent it downward.
Good luck!
Mike

If the soffit is made up of individual pieces, then you can get them loose without much trouble. There is a siding tool called a "side swiper" by Matco tools that is used to remove individual pieces of vynil siding and soffit to make repairs.

Soffit vent kits are also available from building supply stores that sell vinyl siding.
