| Added in | Update 2.0 (the description now promises rooftop shelters) |
| Where | On the roof, on the white and blue outlines |
| Materials | Boards (both hands), Box of Nails, Wire Mesh Roll; base boards need a bundle of planks |
| Tool | Hammer (Damage 23, Reach 5.0); pliers seen in the same build |
| When it's done | "The rooftop anchor stands." |
| Why | The Cold meter rises on the roof; the shelter is warm enough to wait out a night |
Build steps, as the prompts read
| Step | On-screen prompt |
|---|---|
| Base boards | "Base boards - needs a plank (bundle of planks)" |
| Back brace | "Anchor outline: the back brace - needs a board", then "The board's in place - nail it" and "Nail the back brace - needs nails" |
| Left leg | "Fit the board (anchor left leg)" (hold E), then "Nail the left leg - needs a hammer" |
| Right leg | "Fit the board (anchor right leg)" (hold E), then "Nail the right leg" (hold) |

The Cold meter
Update 2.0 footage shows a COLD bar above Health that only fills while you're on the roof. As it rises the game warns you twice: "The wind up here cuts straight through you. Get inside the hut or a proper shelter, or go back down." and then, in red, "You're shaking hard. Get under cover now."
So build the shelter before you plan long roof jobs like the garden or the rain barrel, or go back inside when the bar gets high.
Where the materials came from
In the footage the player carries boards up the stairwell one at a time (a board takes both hands), picks up a Box of Nails in the corridor, and takes pliers and a hammer from apartments and a red toolbox. A board on the stairs had to be set down before opening doors.
Tips
- Carry the hammer and nails in your slots before you go up with a board: you can't fit and nail with your hands full of something else.
- Do roof jobs in daylight and keep an eye on the Cold bar; the warning comes before the danger message.
- Build with a friend: one carries boards up while the other fits and nails.

What does the rooftop shelter do?
The game describes it as "tied down, out of the wind. Warm enough to wait out a night". It protects you from the Cold meter that rises on the roof.
