Does roofing felt serve an additional function when laid under a
hardwood floor besides being a moisture barrier?
I'm installing 3/4" plank in an upstairs room over a plywood
sub-floor.
Do I need felt underneath?

I think it is also used to control squeaks. That said I would use 30# felt
and not the cheaper 15#.
