If you can force them to build the roof the problem is not lack of wall support.
Rimworld build walls without roof.
Simply build a room in any shape or convert them from ruins and then deconstruct a few sections of wall facing the enemy to make some holes and replace with sandbags these will be firing holes for your shooters where they can use the walls as cover for 75 protection from direct fire and sandbags as cover from diagonal fire.

In a more general way any roof away from a wall by more than 6 tiles will collapse be it natural or built roof.
Enclosed areas will automatically prompt colonists to build a roof unless you apply a no roof region or if the structure is too large over 300 cells.
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.
Structures leave ash on the ground when burnt.
The workers only built the floor and walls and doors but still no roof.
