I am seeking a solution to a pretty serious mold problem. I recently bought a 1800 sf ranch that has a large front porch that is covered by trusses that overhang from the front of the house. The problem is that two bath fan vents come out in the porch ceiling and the dryer vent comes out of the rim also under the porch. The moist air from these vents is getting sucked up through the soffit vents at the outer edge of the porch and is condensing(and by the looks of it has been for a long time) on the back of the roof sheeting. The first two pieces of plywood are black and furry.
So here is my question: I plan on replacing the roof plywood, and reroofing the whole house. Where do I route the vents from the two bathroom in the front of the house and the dryer?
We get a lot of snow here and I don’t want to go out the roof and have the vents get buried by snow. I figure the warm exhaust would melt it and cause ice dams.
I also don’t want to go out the gable end because the house is log and I dont want water running down the logs either.
Am I stuck or is there a good solution to this. I love the house and want to stay for the long haul.
Thanks in advance for any help.
