This year my lawn is more rough than the past few summers since I bought
the house. Its difficult to even walk on!

What can be done to smooth it out without stripping off the sod and
starting new? Would running a seed roller over it the aerating help?

You can do a couple of things:

Top dressing

Serious aeration followed by rolling.

You may have to do several cycles of either of these approaches, depending
on how rough the lawn is and how smooth you want the lawn to be when you're
done.
