Make sure the blue side is facing the room and the red side is facing out make sure the room is enclosed and has a door the bigger the room the more ac s you need.
Rimworld built room but roof not working.
Indoor roofs are automatically built by builders.
There are a few things that come into play when colonist build roofs.
A roof collapses if there s no support rock wall within 6 squares of the tile.
This means that the largest square room you can have is 10x10 internal.
If there is any tile with is not in that range the roof will not be builded or that tile will not be builded.
And that is for everywhere from every side.
Building won t roof back over so i was building an indoor farm next to two geothermal generators which were unroofed by zone while the farm was being built and after the construction is done the farm won t roof over.
If you removed 2 entire walls and the corner between those two sides last then that roof was too far away from any other supports.
Trade beacons will work under a roof.
Items purchased from a trader will be dropped within range of a beacon if unroofed otherwise they will be dropped as close to the beacon as possible avoiding.
To build a roof outdoors a build roof area must first be drawn.
The no roof tool highlights areas that should be considered outside.
A roof will not be fully built in a room that is more then 11 blocks between two parallel sides.
Make a hole in your room and then close it to trigger the roof build.
If the room is open in some area or the door gets jammed open all the cold air escapes.
Larger roofed areas can be built with the use of interior walls as pillars.
The roof is supported far as 6 tiles.
If that distance is more then that then you will only get a partial roof around everywhere but the position where it lacks enough support.
Solid walls and separate rooms will break the area of influence of a trade beacon however support columns for larger rooms don t block its effect.
You can select one of your colonists and then right click inside the room and prioritize building roof should be an option.
I personally think it should work the other way but there you have it.
As long as there is no other work to be done in there with a higher priority the colonist will finish building the roof.
Make sure you click on the ac and set it to 10c for freezing or more 0c for refridgeration.
Areas can be designated to have a roof or not have a roof by drawing either a build roof area or remove roof area.
1 does the roof have support.
