I live in Washington State. Yeah I don’t know if it was like this originally or if the previous owners just stuck the netting on there to stop animals from getting in.

You’re right that there isn’t really any space between the ceiling and roof. The venting is the main thing I’m concerned about and moisture. I think things are already a bit wet to begin with because of the trees, moss, and pine needles that like piling up. Maybe I’ll try to take a closer look behind the sheet rock and see what is going on.

Thanks for the input and recommendation. There are 2 skylights at the eve and a door which you can see in one of the pics. If you think that would make any difference with anything.
