The Red Adobe Roof is a slanted brick-red building-block that you can only craft in your Crafting Menu (default key "Q") after finding the according Recipe per chance, which is a rare loot from the Thing (as a loot or pet-harvest) or can be found in Iron Treasure Chests spawning on blocks from the Lava layer, or in Diamond Treasure Chests spawning on corrupted blocks like found on the Corruption Layer.
To craft 8 blocks of Red Adobe Roof you'll need (as of R43 in May 2017):
- 1 Stone Rod, made of Stone, Limestone or Bedrock in a Processor
- 2 (blocks of) Adobe Bricks made by putting Mud in a Forge together with Fuel
- 1x Red Pigment made of Red Flowers from Ashenwood trees in a Processor or as can be found in Obsidian Treasure Chests
- 3 Wood Slabs made of any kind of Wood (except for corrupted Wood) or Log in a Processor
Since R42 in May 2017, inner and outer corners blocks can be created for Red Adobe Roofs too by putting them into a Processor. No crafting recipes are required for this.
