Leaf Roll and leaf curling are two different phenoms.

Leaf Roll is a condition seen usually at the beginning of the season when root and foliage mass are not in balance and it disappears as the plants mature.

Leaf curling is usually seen as a response to almost any stress, whether it be too hot, too cold, too dry or too wet, and also when plants have a heavy fruit burden and most modern hybrids have leaves that curl normally.

So unless there are other symptoms I'd ignore it.

If the leaves are curling over into a tube like structure you might want to check for aphids.
