If your landscaper prepped and leveled the soil beforehand, it does not need to be rolled. You should be watering at least 2-4 times a day that will keep the sod from drying out and help establish the roots. You should feed the new grass monthly and I suggest you look up the type of grass or google new lawn + your state + edu to find a publication on how to take care of your new lawn. If you pay a landscaper to put the lawn in, that is what they do, it becomes your job to take care of it afterwards. Most landscapers will give you care instructions, but I do understand why they don't volunteer it if they are not asked.
