"My range hood is vented to the soffit on my roof eave, is this acceptable?" --------- Possibly....
Needs to terminate outside,
3' minimum away from any openings into house (doors, windows, air supply, etc.) and property line. Requires
a backdraft damper, very hard to do in a soffit application.
A good idea? NO- the soffit intake vents will bring the greasy/moist air into the attic to settle on the insulation. Check with your LOCAL B.D.
