I have found that the underwear at the bottom of the pants (and therefore, the center of the roll) is essential to making sure your shirt doesn't get wrinkled. It creates a bit of a core for everything to roll onto, which decreases wrinkles at the bottom of the shirt...even though that part ends up tucked in anyway.
I can post pictures and diagrams if a more detailed how-to is requested.

Only difference is I roll the full length of the pants, and fold the shirt in thirds over the front, which keeps the collar from getting crimped. If you have showers, put the shirt on a hanger near the showers. Warm humid air takes any non-creased wrinkles out.
I also found that underwear core trick, and agree that it makes a huge difference.
