Usage tips
Word composition
The word is made up of 'Dach' (roof) and 'Stuhl' (chair). Here, 'Stuhl' does not mean the piece of furniture, but has its older meaning of 'frame' or 'supporting structure'. So the Dachstuhl is the load-bearing framework of the roof.
EXAMPLE
Die Zimmerleute errichten den neuen Dachstuhl.
The carpenters are building the new roof truss.
Context: construction and architecture
'Dachstuhl' (roof truss) is a technical term from construction. It is used when talking about the structure of a roof, often in connection with new construction, renovation, or also fires.
EXAMPLE
Der Architekt prüft die Statik des alten Dachstuhls.
The architect is checking the structural stability of the old roof truss.
Typical verbs
In connection with the roof truss, verbs such as 'errichten' (to build), 'sanieren' (to renovate), 'ausbauen' (to convert/expand), or 'erneuern' (to renew) are often used. In fires, you often hear that the roof truss 'in Flammen steht' (is in flames).
EXAMPLE
Viele Leute bauen ihren Dachstuhl zu zusätzlichem Wohnraum aus.
Many people convert their roof truss into additional living space.

Dachstuhl vs Dachboden
attic
'Dachboden' and 'Dachstuhl' both have to do with the upper part of a house, but they do not mean the same thing. The 'Dachboden' is the attic, the space under the roof. You can often store boxes, old furniture, or other things there. The 'Dachstuhl', on the other hand, is the load-bearing structure of the roof, for example the beams. The words can be confused because both are located directly under or in the roof area. A practical way to remember it: you can go up into the Dachboden; the Dachstuhl is something you are more likely to see or repair as part of the building.
Dachstuhl
Nach dem Sturm musste ein Handwerker den beschädigten Dachstuhl prüfen.

Dachboden
Auf dem Dachboden stehen noch die alten Koffer meiner Großeltern.
