What are trussed rafters?

Trussed rafters, or more commonly known as roof trusses, are the ideal solution for the structural framework needed to support the roof fabric.

Since their introduction to the UK in the early ’60s, roof trusses have proved to be a fast and economical method to form roofs.

Roof trusses offer a vast amount of flexibility and can be used on a wide range of building types including both domestic and commercial structures.

Trussed Rafters

Using quality-controlled jigs, trussed rafters are formed using TR26 graded timber held together using Wolf’s connector plates.

There are many various roof styles that are designed for architectural preferences or to match into existing surroundings. Larger spans can be easily achieved by using a heavier section timber, closing the truss centres or making double trusses.

Hipped Roof – General Construction

Once only achievable as loose-cut sections of timber, these roof shapes can now be created by assembling a collection of prefabricated specialised truss components. Using a combination of flat-top girder trusses, mono trusses and loose timber infill, a Hip end can be formed quickly and efficiently.

Types of roof trusses:

  • Fink trusses – A standard truss configuration utilised in most common roof shapes, such as a gable-to-gable dwelling.
  • Hip trusses – Usually used to create a hipped roof, that is then sloped on all four sides. Can also be used for pitched flat roofs.
  • Mono trusses – Mainly used in conjunction with hipped roofs, but also as a single sloped roof.
  • Raised tie trusses – Raised tie trusses are used to increase the height of a ceiling in a room.
  • Scissor trusses – Scissor trusses follow a similar purpose to raised tie trusses, the difference being that the space is increased mainly in the centre, with sloped ceilings leading up to the middle.
  • Attic trusses – Also known as ‘room in the roof’ trusses, attic trusses are built entirely with that purpose in mind.
