The roll cast is going to open up all kinds of fishing for you. It's easier to get into places where a back cast would be impossible & it's going to make you way more accurate in tight quarters. That's good enough, but it's not just for tight quarters either. The roll cast can be the answer to your troubles on windy days, too.
I could go on all day about how it's the most underrated cast but instead, I'll just share this video with you about it. The instructor in this video does an excellent job of showing us the roll cast.
