Trusses (or Trussed Rafters)

Trusses (also know as trussed rafters) are the structure that makes the shape of your roof. Trusses are usually made of wood, although some other materials are occasionally used.

The picture below shows a standard set of 'attic trusses'. There are a variety of types of truss and you can find out more about this in our Roof Structure and Guttering information section.
