Where to vent the dryer and range hood exhaust?
I am building a house with the dryer and the range located in places where it would be difficult to vent them anywhere other than through the roof or through the vented soffit at the eaves of the house. (It’s about a 40 foot run to get to the gable end)
I understand that venting an appliance through vented soffit means that the humid air will likely get sucked up into the attic where you don’t want it. However, reducing roof penetrations appeals to me and I am concerned about lint build-up being harder to deal with if the dryer is venting through the roof.
(The house is for my parents who tend to use the clothes line to dryer clothes whenever possible. Because of this, I am reluctant to have them install a ventless heat pump clothes dryer due to the high up front cost and the mixed reviews I have read on the available models.)
One option I thought of for venting through the soffit would be to install non-vented soffit for several feet on either side of the exhaust outlets to lessen the chance of humid exhaust air going up into the attic. The attic is open so air from other parts of the soffit would be able to flow freely to supply ventilation to roof areas directly uphill from the unvented soffit area. I am using vinyl soffit, so I realize that even the unvented soffit panels would probably be rather leaky at the joints.
