When I purchased my house, during the home inspection it was indicated that the bathroom vent is simply discharging directly into the attic space. Because we were concerned about mold in the attic, we've simply not used the fan. The inspector indicated that we'd need a vent pipe that went straight up through the roof.
My attempts to hire someone to do this work continue to fall flat, but in speaking with a contractor the other day, he'd indicated that the vent could instead go through the roof soffit instead of through the roof itself. Is this accurate? I wasn't sure if this would create condensation issues either in the vent line or along the side of the house where it vents out.
I saw several other questions relating to this which all seem to indicate this is a bad idea, but they're several years old and I'm not sure if there have been any changes in technology that would make this more viable (maybe modifications to the soffits around the discharge point to prevent the humid air from being pulled back in and preferred pipe slopes to prevent condensation buildup).
If it's relevant, we're located in South Jersey, which sees a lot of temperature fluctuations throughout the year (and often throughout the day).
