FloorsAreRoofs is a Valheim mod that makes wooden floor pieces count as roofs, so you can place beds and workbenches underneath flat ceilings, gain rested and comfort bonuses, and stay safe from rain – no angled roof pieces required.
Version 2.0 adds config-based support for custom building pieces and hammers (like Odin’s Architect). Drop the .dll into Valheim\BepInEx\plugins, launch once to generate the config, and tweak which prefabs get weatherproofed. 🔨
