 Two sloping verge of the house can be constructed either by outrigger & fly rafter or pre-nailed boxing. Outrigger is to overhang on verge of truss by 405mm and fix with fly rafter of 45mm at the end, a piece of diagonal outrigger is set approximate 45 degree setting on top of end truss and fixed onto fly rafter and outrigger. With boxing verge, it is to be constructed with nog and fly rafter on ground, then fixed onto the end truss.

Mark out position of each individual trusses on top plate at both side of the building, each truss are spaced at 890mm center to center. Mark out position of perlins before the truss pack is open up or the conveniences when fixing in future

Starting fixing trusses from both end of the roof and brace up with timbers on to the timber floor, level end trusses and tag nail pieces of timber on face wall framing. set string line on the ridge on both trusses (the end with a lower truss design for fixing outrigger has to set form the second one in which is same to all other trusses), use dogger block and pack under string line on both end then use it as a mark for setting other roof trusses
