Another one of our jobs was an extended premises where a hipped roof had to line through, the pictures show what is known as a hip section, these include;
1. Hip joist
2. Jack rafters
3. common rafters
5. wall plate
6. Ceiling joists
7. Fascia detail
All works passed by local authority
Roofs Trussed ( preformed ) and traditional.
Basic tool requirements;
First fix nail gun
The main set of photos show a roof being fixed to a comunity hall in Scotland. The first photo shows me working on a lower section, this is typically known as a trussed mono pitch. Basically a wall plate is fixed to the top of the brick height and then Trusses are put in at usually 600mm centres, you start with fixing the 2 furthest trusses apart. When they are levelled you string a line at a lower point for ease between the 2 trusses, then simply put the others in between , offering the trusses to the line, this ensures a perfect line for the tiles to sit. This job then had 100x50mm perlins fixed @ 600mm centres horizontally.
The next part of this roof then shows what are known as king pin trusses, they are fixed and usually visable from the underside. Again these are fixed at pre determined centres and lined through. When levelled perlins were fixed horizontally to the trusses ready for tiling. The other roof in the photo was above a shop, this shows an extension to a hipped roof section. This time we didnt use pre made trusses we formed a traditional roof using 150x50mm softwood timber.
The photos show the hip rafter section which is the part that reaches the top of the roof the ridge to the bottom which is called the wall plate. This is put on an angle from the centre top of the roof to the corner bottom.It is basically an extension of the ridge board and keeps all jack rafters in line.

So at the out set of the work to put on a roof you firstly fix a wall plate to the top of the brick line on the inside skin, this holds the rafters in place when fixed. With some basic trigonometry, you can work out all angles to cut your timbers at, these cuts are plumb cut and seat cut on the common rafters, the plumb cut is at the top that meets the ridge board and the bottom vertical birdsmouth and the seat cut is the horizontal cut that sits on the wall plate.
If it is a gable end house, the brick work meets the ridge at both ends, you would cut all common rafters at the same measurement with all plumb cuts and birdsmouths cut out. Then place the ridge board at top centre, the next steps are to fix the 4 common rafters at each corner, 2 either side so it is supporting the ridge board , then put a line through on both sides at wall plate level and offer rafters to this line. which keeps the ridge perfectly straight.
Your next steps are to line through and trim fascia line to recieve fascia boards then battern out for soffit which is the underside overhang you see when you look up. Then you are at the stage to fix fascias and soffits to your building, and get weather proof for the tiler. That was a basic explaination of how to put up a traditional roof , if it were a trussed roof, its a case of fixing wall plates, placing a truss either end of gable string line through one side and fill in the roof space with trusses fixing where it meets the line. Facia and soffit detail would be the same process as above.
