30 Floors Up Roblox rooftop: how to get onto the roof

Why can’t you take the stairs up?

Players who climbed the stairwell to the top found the roof door with “something heavy stacked against it”, locked from the roof side. There is no way to open it from inside the stairwell in any recording so far.

How do you get onto the roof?

1. Get the triangular key. It is in the toolbox in your apartment’s main room (keys).
2. Open the elevator doors on your floor with it.
3. Climb the emergency ladder in the shaft. One guide says the first trip up has to go this way and that you also want the wrench with you.
4. Go in daylight with a light source; the shaft is dark.

A walkthrough from 7 November shows exactly this: triangular key from the toolbox, elevator door open, up to the rooftop.

What is the roof key?

When you talk to Arthur Hail, one player noted that he mentions the roof key being “on the bench”. It likely opens the stair door from the inside, which would give you a second way up, but no recording shows it being used yet. See Arthur Hail.

What is on the roof?

• The water tank. Turning the valve riser on floor 27 pumps water up to the rooftop tank, which then feeds the taps again (water). Arthur also points you to “the roof tanks”.
• Shelters. The official description says you can “build rooftop shelters”. One guide says the rooftop unlocks your long-term survival route. How shelter building works has not been shown in a recording yet.
• Escape. Daniel tells you “we need to get to the roof”. See how to escape.

We will add the shelter steps once a recording or our own run shows them.

What stops players reaching the roof?

Blocker	What players did
Stair door blocked and locked from the roof side	Gave up on the stairs and used the shaft
Triangular key left at home	Went back for it; take it on your first trip out
Dark shaft	Brought the flashlight; the shaft has no light after the cut
Night falling during the climb	Turned back to sleep; fatigue and darkness make the shaft dangerous

Why does the roof matter?

Three separate sources point there: the official description promises rooftop shelters, the water from the floor 27 valve is pumped to the roof tank, and Daniel says you need to get to the roof. One guide calls it the start of your long-term survival route. That makes it the first place to scout once you have water and the triangular key, even though the shelter steps have not been recorded yet.
