Leave as-is. Good soils do compact a bit underfoot. That's their job. Walking on my lawn is an exercise in Feeling the Sponginess. What I compact today will be aerated and expanded again by the soil life over the next few days and return to where it was.

Even if the rolling wasn't good enough (it probably was), the roots in there now aren't going to like being rolled again, nor will the young and very delicate crowns of the new grass. And by the time it's old enough, the soil will have compressed itself down appropriately and you'll probably never notice any very minor height differences.

Thanks, Morpheuspa! After all the initial work we did I needed that reassurance. :)

I'll second that. You'd crush the new seedlings by rolling again.

Rollers are water fillable. You should fill with water until you can no longer see your footprints in the soil behind the roller. Of course that won't help you, but someone else coming along later will see this and get the tip.
