Truss grips still in the box
The roof is held down by small pieces of metal that are easy to forget.
In short: Triple grips are cheap, quick and structural. They are also the item most often left uninstalled.
What a truss grip does
It ties each truss to the top plate so the roof resists uplift. Without it the roof is resting on the walls rather than fixed to them.
What we recorded
Grips absent at multiple truss positions on a home where the rest of the frame was otherwise well built.
Roof bracing too
On the same job the roof bracing had not been installed, which is the other half of how a roof structure stays square under load.
Timing
Frame stage, once trusses are up and before sarking. After lining, the roof space is accessible but awkward and items get missed.
What good looks like
Grips at every nominated position, fully nailed, with bracing installed and fixed to the pattern on the truss layout.
