The Yellow Adobe Roof is a building-block that you can only craft in your Crafting Menu (default key "Q") after finding the according rare Recipe per chance, which can be obtained as a loot or pet-harvest from the Thing or can be found either in Iron Treasure Chests spawning on blocks of the Lava layer underground or in Diamond Treasure Chests spawning on corrupted blocks like found all over the Corruption layer.
To craft 8 blocks of Yellow Adobe Roof at a time 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 hardening Mud in a Forge together with some Fuel
- 1x Yellow Pigment made of Yellow Flowers from Cragwood trees in a Processor, or rarely found in Obsidian Treasure Chests or Iron Treasure Chests
- 3 Wood Slabs made of any kind of Wood (except corrupted wood) or Log in a Processor
