If a roll is needed at all, I call for Investigation or Perception for traps, then Investigation (again, if needed) to figure out how the trap works before it can be disabled. For secret doors, it's Perception to find it, then Investigation to figure out how to open it, if a roll is necessary. Each task takes about 10 minutes, so a given trap interaction can take about 30 minutes of in-game time, and secret doors about 20 minutes.I use Investigation more in my games. If players say they want to search the room, I'll ask for either Perception or Investigation depending on what I think the answer is.
So we might see the rogue or the cleric or even the wizard out front searching for traps (though the wizard tends not to be so brave!).
