If you are making a game with scrolling, you should probably get used to the idea that you will be re-drawing everything every time.
Even if you're not doing scrolling, redrawing everything each frame is usually the simplest thing to do. In a tile-based game, you end up blitting just as many pixels either way, and that's usually where the bottleneck is. If optimization is needed, use dirty rects or something like that. -- Greg
