The correct SQUARE formula is 3-4-5 triangle.......3x3+4x4=5x5 (or double or triple each number).....depends on how long your tape or clear space is...............

But as posted above: what about the span between rafters.........what decking are you using? That's mighty far spaced at 14 rafter/trusses over 70'...........What material will bridge 5+ feet with a snow load.........And what is the planned roof surface material?
