The tables below give maximum spans for rafters and beams. Pitched roofs are generally used where rainfall is heavy. A howe scissors truss is so called because its appearance resembles that of an opened pair of scissors. The picture below shows the pitch of a 7 12 roof slope meaning that for 12 of horizontal measurement roof run the vertical measurement roof rise is 7.
