how do you setup roof trusses?

Answer 1

I always add another two by fore to the top of the walls then every 2 feet i cut a slot the width of a framing square which is thw width of your truss 1 and a half inchs deep that way they fall in a slot and no one has to hold the truss when you nail it. then all you have to do is start with the first one and ues a level to get it straight usr bracing to hold it there. then all you have to is drop each truss in there precut slot then measure from the first truss 2 ft. and you it.then 4 ;6;8;etc. bou nair a brace on top to hold each one in place untill you are done then you can deak it.

Answer 2

as you hold the first one in place - the second is moved in
and a temporary set of lumber is nailed in place to stabilize

once the rest of the roof goes on - the temporaries come down
