Mod «Expanded Roofing» for Rimworld (v1.4)

Expanded Roofing

Adds customizable roofing, with transparent greenhouse roofing and photovoltaic solar roofing. Reworked from Vendan's original idea.


  • Transparent roofs that let almost all light through
  • Solar roofs and controllers that can be used to generate power
  • Removal of thick roofs
  • Thick roofs (which require maintenance as of Late A17/B18)
  • 4 new techs to research for each of these features.
    Disables settings when `Don't Tempt Me!` is enabled (Vassteel Rydex's request)

Solar Roofing and Controllers explained

  • Each controller has a max output of 2500w
  • Each solar tile produces 200w during full sun
  • There is no limit to the number of controllers connected to a section of tiles

Roof Maintenance

  • Maintenance required for thick roofs (only)
  • Maintenance is a long tick (once every 2000 ticks)
  • Maintenance is required after 5000 ticks (~167 days)
  • After 7500 ticks collapses can occur by MTB event. (~250 days)
  • MTB event is set for 3.5 days.
  • These numbers are subject to change.


  • Is compatible with any existing B19 save with no other roofing mods
  • It's recommended to have this mod load early in your mod load order


  • New designators are in the `Zone` tab
  • Due to how roofs are implement, it's easiest to rezone default roofing to new types
