Pitch of the Roof Truss of its Slope

  • For appropriate drainage, a roof truss’s pitch (Rise/Span) should be 1/4 to 1/6 of its slope. Pitch for symmetrical trusses is equal to the top chord’s inclination divided by two.
  • The roof trusses are spaced at 1/3 to 1/5 of the span.
  • Trusses for roofs typically call for relatively light members.
  • To prevent damage during shipment, a minimum ISA 50 x 50 x 6 mm angle section should be included.
  • At least 2 rivets must be used to join any member to the gusset plate, which must be at least 6 mm thick.
  • As a result, the roof truss is typically equal to one-fourth of the slope.


The pitch of the roof truss is usually ________ of its slope. (a) half (b) one-fourth (c) double (d) three-fourth

The roof truss’s pitch corresponds to one-fourth of its slope. It is cost-effective for spans more than 6 mm. It comprises steel connector plates, internal web members, top chords, and bottom chords at all junctions.
