truss roofing

step 1,before erecting the trusses check that the top plates are flat plumb and secure we set our wall plates on desks aranged around the classroom and fixed the plate to the desks.

step 2,we grabed all the trusses from outside brand them into the class room and set one standard truss at one end and another at the other end put a nail on the apex of both and run a string line the whole way through setting up and fixing each indirvidual truss one be one keeping them plumb on the string line fixining with a triple L grip.

step 3,then we fully braced the the main roof useing a speed brace fix with 30x2.8mm galv reinforced head nails.

step 4, then we fix our truncated girder trusses in place keeping them straight with a sring line then we grabbed the jack trusses and creepers and fixed to bothsides.

step 5, the we screwed facia clips all the way around the roof keeping them at the same height with a string line then we fixed facia.
