Protection From Events

Rimworld sometimes experiences random events. Despite some positive events, more often than not, there are negative ones. Toxic fallout can be one of the worst events if it is not managed properly. When outside, colonists and creatures will be affected by toxic buildup.

Creating pathways on roofs can completely mitigate this problem. Your colonists won’t be negatively affected by toxic fallout if a roof covers their entire walking area.

Your only concern should be to have a decent supply of food. Connect every room with a roof if you have enough to support your colony. Roofs can be built with just a few supports every few tiles. Change the allowed area of your colonists after you have built your series of roofs, and only paint the roofed areas.
