HI How do i avoid a rood collapse on mountains ? Basicly i want to get rid of the whole mountain but so far ive lost about 5 pawns when they have been trying to do this in mountains.

Thanks !

Hello, in vanilla there is currently no way of removing mountain top roofs. There are mods that can do it. If you use mods, i can find you one that does what you want :)

Roofs must have a support or they collapse. Any roof more than 6 tiles away from a wall will fall. To build larger rooms you will have to put even just a one tile wall as a pillar in the appropriate locations to keep the roof up.

Perhaps someone knows a mod for removing overhead mountain so that you can demolish the mountain safely. Maybe a search on the workshop for overhead mountain will get a result.

This is the mod i personally used for removing mountain tops in some earlier playthroughs. After finishing, you still have to use "remove roof area" on the part that has been removed. enjoy

This^

If you want a visual example, place a single wall in the middle of no where with a biiiig square roof around it. You can then see where the pawns build for the exact size a single wall can hold.

There are several mods that allow for removing mountain roofs. Some have research requirements and some have less or none. If you feel like adding a mod to do what you want, you can decide if you want this to be "free" or something you should have to work for. The same 6 tile roof rule works for constructed roofs as well, and you can also use the bounded roof mod to make sure you don't accidentally build a roof that will collapse.

Keep in mind that tiles mined out under a thick mountain roof can cause infestations to spawn, too.

Myself, I prefer the one on the left - less disastrous if a pillar gets destroyed. I use that for open areas when building within a mountain. You can space them out further, but the one on the left just results in a single ceiling piece dropping of one pillar is removed.

Since your plan is to remove the entire mountain though, I would remove the roof completely (as Preechr mentioned, to prevent infestations). But to do that, you need a mod as everyone else has mentioned lol.

I kind of like the roof collapse mechanic. You can weaponize it if you know how to set it up. The roof collapses inside of the mountain are a 100% kill if it falls on someone. Worth looking into if you want a unorthodox style to your base defense.

Funny when raiders ignite the wooden pillar, and move to sandbag cover around it. 😂👌
