the class has been divided into two teams with the job of building a truss roof
Our roof has a tiled roof.first job was to put down the bottom plates,they were leveled up and clamped down.We then started erecting the end trusses.They were plumbed up and braced securely into placed.The standard trusses were then all stood up in pla
ce.A string line is then placed between the two out side trusses to line up the apex or roof line.The heels are then screwed down in place and the tops were plumbed up and the top batten screwed on to secure them from falling over.The girder trusses were then placed on,in line with the bottom plate and screwed in,hanger brackets were screwed on to support middle trusses.Middle trusses were put on and then girder trusses were plumbed and screwed down after they were plumbed up.All trusses were then triple griped.Jack trusses were then put on,lined up and screwed into place and triple griped.Saddle trusses were placed on main roof,the apex was lined up and battens made to suit to hold them in place.Speed bracing is then place over main roof at plan or manufacturer's instructions.Creeper trusses were then added.The rafter are then string lined to length and cutoff.Metal fascia clips are screwed on to the end of the rafters and the metal facsia is clipped into place.the valley is then found using a string line and then measured out to find were valley boards will sit and then screwed down.Once all valleys are done the whole roof can be battened out to suit the tiled roof.
