I would keep them locked in the coop for a day or two (assuming it is light in there during the day) so they recognize it as "home". I would also put a smallish light in there for evening so it's appealing for them to enter the coop as it gets dark outside.
I don't know why you would insist they sleep on the roost; if the floor is properly bedded it should be warm and comfy for them to sleep in the shavings. My hens sleep on the roost, and my rooster prefers the unused nest box that is at floor level...works for him, works for me!
