Dryer vents…you can’t point them just ANYWHERE.
The surrounding loose fiberglass had been soaked and dried repeatedly over the years and had congealed into solid matts. The patch of moisture damage fiberglass was about a yard across.
The roof sheathing overhead showed loads of evidence of moisture condensation – staining, small amounts of rot around the roofing nails.
Obviously, it needs to be vented to the outside.

This reminds me of a poor design my grandmother’s house has. The dryer vents into the garage. It takes 90-120 minutes to dry a load of clothes, right? So the problem is every time you dry clothes you have to open the garage doors, otherwise you have a risk of a very hot garage, fire, etc. So that 90-120 minutes while her garage door is open is a perfect opportunity for someone to steal her car, lawnmower, freezer, hide in her garage and wait till she comes out to mug her, etc.
