I have a 6*9m colourbond garage im putting up.. but the trusses have me stumped.

One truss is part of the back wall, the other on the front is flat and sits on the wall beams without problem.

Two internal trusses however are slanted so that they dont sit flat on the walls and the instructions claim you just use a little hexscrew(same used for the colourbond) to attach them.. the whole thing seems extremely unsafe and infact I managed to get one up with some screws in it but they were hardly in and started pulling out as I tried to get the purlins attached..didnt help that I had a 80kmh wind come up just as I got the screws in which had the whole structure swaying.

Is this normal... more so I ask because they managed to "accidently" send me instructions for another shed entirely which I caught when going over the plans and rang them up over and they told me to throw those out...
It seems to me all the Trusses should be like the end truss and flat so its sits stable and flat on the walls.


Here is doodle to show what I mean it doesnt sit flat.

As we have high winds here including minitwisters one which was powerful enough to push all the the tiles up on one side of our house like a person had gone along and done it, I really am after the best most secure way to attach the roof, I have put in double the bolts into the slab so the walls wont be going anywhere but the roof is now the problem.

I also have a second problem I think... how do I attach the colorbond sheeting to the roof, can you sit on the purlins/trusses or do I need scaffolding?
