I have a small bathroom with exterior walls in an area of my home with a vaulted ceiling (and thus no attic access.) When I moved in, the exhaust fan was uselessly "exhausting" directly into a fiberglass batt.
I'm hesitant to cut a hole in my roof to exhaust the fan properly, but if I go a few more feet I think I can access the soffit area and place a vent there. What I'm not familiar with is whether or not I can expect some kind of obstruction between the roof joists over the exterior wall.
This is a rough sketch of what I intend to do – however, before I go yanking the existing insulation out from between my rafters to make room for the flex duct, can anyone tell me if this makes sense? Should I be able to snake a flex duct between the rafters and into the void between the soffit and overhang?

Welp, it worked out just fine! Still need to caulk it and paint it, but it installed easy and it's amazing the difference a properly vented bathroom makes.
