Nether roof

The Nether roof, with red and brown mushrooms spotted around.

The Nether roof is the largely empty space above the bedrock ceiling of the Nether. In contrast to the void, the player does not take damage from the Nether roof.

In Java Edition, the player can place blocks up to 128 blocks over the Nether roof. The Nether roof was once seen as a bug, but is now unofficially maintained by Mojang.

In Bedrock Edition, it is not possible to build on top of the Nether roof. A player who manages to get there is teleported back into the main part of the Nether upon reentering^{[clarification needed]} the world. As such, the space above the Nether ceiling is not usable.

Accessing and exiting

Because the Nether roof is technically unintended behavior and it is not possible to break bedrock in normal gameplay, there is no proper way to access it. Therefore, bugs must be used to access the Nether roof; the most common way to do this is to teleport through the bedrock blocks with ender pearls.

Once on the roof, in Java Edition, it can be exited by making a hole in the bedrock layer or by making Nether portals. In Bedrock Edition, it can be exited by leaving and rejoining.^[verify] Both methods in Java Edition can be used to gain permanent access to the roof, since portals built on the roof can link to corresponding portals in the Overworld.

Generation

With Vibrant Visuals, the Nether roof has unique red ambient lighting bleeding about half a block down.

The Nether roof is completely flat, consisting of only a layer of bedrock. Mobs do not spawn on bedrock and therefore can spawn only if a player places blocks on which they can spawn.

In Java Edition, brown and red mushrooms can be found on this bedrock layer.

The Nether roof does not have its own biome. Instead, its biome depends on the biome under the roof and the lighting changes with the biome as it would below the Bedrock layer.

Usage

Because a great deal of empty space is available, the Nether roof is an excellent location for building farms that require mobs to spawn, such as hoglin farms, gold farms, and bartering farms.

The Nether roof is also useful for building transportation networks. The Nether allows for 8 times shorter travel distances, and by building Nether portals, it is possible to travel quickly between destinations using ice highways or other methods of transportation. Although it is possible to do this below the Nether roof as well, building these transportation systems on the roof is easier, since there is less terrain and there are no natural mob spawns.

Trivia

• When discussing uses of the new happy ghast during Minecraft LIVE – March 2025's after-show, a developer mentioned high-altitude builds on the Nether roof.
• The Nether roof was most recently mentioned as a visitable place during Minecraft LIVE – March 2026.
