The room was too cramped for maneuvering. Sasuke flew through the hole his Great Dragon Fire Technique had left in the ceiling and onto the rooftop.
Itachi also used the wall for leverage, taking several steps before leaping onto the roof in pursuit of Sasuke. Sasuke had been prepared and gave Itachi no chance to steady himself.
