Bracing roof trusses, necessary?

[busgraab]

Hey!

Here is what my construction of a small cabin looks like:
7m long, 5m wide, roof angle 22 degrees. It will have 17mm tongue and groove boards on the roof.

Since I'm using tongue and groove boards, I assume the roof doesn't need bracing?

Hypothetically, sliding could occur in the tongue and groove and could cause the roof to collapse, but as far as I can see, you don't use or need bracing/cross bracing from ridge to wall plate when laying tongue and groove boards?

Best regards, Henke

You don't need to use cross bracing on your roof. The råspont binds it together.

Although we heard from an acquaintance that in the new building regulations (that are coming or have come?), wind braces are still required. In Germany, it has been that way for a long time. New times, new weather, new regulations. We put a brace on each side. Unnecessary - maybe. Simple - yes.

and this is easiest done by attaching a long 21*95 on the inside truss from the first truss's bottom at the hammarband and then extending it to the ridge on the furthest/ as far as the board reaches?

or are there simpler ways?

Sounds convenient, I think. If you put sheet metal on the roof, it acts as a locking mechanism as well.

We used slightly thicker spikband (metal strips on a roll), but a couple of planks will probably work just fine.
