I haven't had any issues with the top leaking. If the windows aren't up all the way, it will drip in at the front corner where it meets the roof panel/windshield. If the windows are up all the way, when you open the door, they automatically move down a little and when you close the door they go back up automatically so you just need to pay attention to that.
