Should I vent bath fan through roof, or soffit?
I am getting a new roof installed (and tear-off and likely a lot of plywood), and am simultaneously getting a new bath vent fan. I have gotten mixed opinions on whether to vent the new fan through the roof or through the soffit (eave). The roof contractor recommends the soffit, to minimize protrusions through the roof. But others have said it will flow better with minimal condensation issues if we go up through the roof.
The house is an early 70's ranch in the cold, wet Northeast.
What are the pluses and minuses of each? Help appreciaated!
