Your roll-up sides will need something to roll around if you want them to roll neatly, typically top-rail. For my high tunnel, I just pull up the sides and clamp or bungie them to hold them up. It doesn't look as neat, but it works.
This stuff is great for attaching plastic to lumber for the end walls and doors:
