I had an inspection completed on a house I am planning on buying
2001 new roof was done - not 100% correct
There is slight mold forming near the ends of the house.

The problems
The ridge vent has black paper covering 75%
(I need to climb up and cut this out I guess)
The bathroom vent goes direct into the attic


The roof has the ridge vent and sofit vents.
Should I add gable vents on the edges of the house?

Since the bathroom is large with a tub and shower and will be the most
used, I want to add a higher end remote fan type installation vented
through the roof. How hard is it to poke through the roof and make sure
the shingles and sealing are ok? Is this a DIY job?

You should not use gable vents along with Ridge and soffit vents. If
you do, it can interfere with the desired air flow from soffit to
ridge.

Fantech inline fans are really nice and very quiet. If you can vent
through a side wall without running the vent line too far that's
usually preferable to going through the roof, But it's no big deal
to go through the roof. There are several styles of vent flashings
for this. See here for an example.

The vent will require cutting back the shingles a little and has to
sip up under the shingles above it.

I am not sure how I would vent through the wall, unless the fan was
mounted on the wall.

If I mount it in the ceiling, that is the attic.
