She's on her break from work and goes up to the roof to talk to Kouichi because she can't get cell service inside the building. She talks to him, then realizes her break is almost over and she has to go back down. The fastest way down is the elevator.

If she'd taken the stairs, she'd have had to hurry, and considering she didn't hang up the phone, she runs the risk of stumbling, loosing her balance, and falling down several flights, which probably would've killed her just as dead (if not as dramatically).
