Replacing Bathroom Exhaust Fan

I have considered replacing the exhaust fan in my bathrooms to something a lot quieter. The house has sheetrock. I could do it one of two ways, from the roof or cut a bigger hole in the sheetrock and then replace the hole with a new piece of sheetrock. This would be more work, but what I’m concerned about is the insulation in the attic. It is the blown in stuff, a 1 yr old house and if I go walking up there, I will be stepping on it, pushing it down, making it less effective….

Any advice?

If you can access it from the attic it will be a cleaner installation with no drywall repair/paint. The vent pipe will be easier fron topside also.

Don't worry about the insulation but stay on the joists

Replacing ex fans from the bottom side is a PITA.

You can wiggle your foot thru the insulation so not much gets disturbed. You can also fill in the holes as you leave. Wear a dust mask.
