The most commonly used truss in residential construction is the W or Fink truss. This truss design is favored for its efficiency and practicality in residential settings. The W or Fink truss is lightweight and provides excellent support for roofs while allowing for ample insulation space and an open attic area.

This design typically consists of a series of diagonal and vertical members arranged to form a triangular pattern, which distributes the load effectively. Its geometric configuration makes it ideal for a variety of roof styles, and it can be prefabricated off-site and easily transported to the job site, speeding up the construction process.

In comparison, storage trusses, scissors trusses, and job site built trusses may also serve specific purposes or applications, but they are not as widely adopted in standard residential construction due to their specialized nature or the additional complexities involved in their design and installation. These alternatives are sometimes used in custom or specialized construction projects where certain aesthetic or functional requirements need to be met.
