The main thing you need to know about rooks is that they work best on open files, meaning that vertically and horizontally if there are no pieces in the way, the rooks fair much better. Chess rooks are only as good as the number of squares they can cover or the pieces that they can support.
One of the common mistakes people make is not activating their rooks. When you develop your pieces you should aim to move all your pieces towards the center, and after you have castled for king safety, make sure that your rooks are always on open files.
