How To Choose Correct Roof Truss Design for Home & Structures

For a better dream house or establishment, grace it with a quality roof truss. This is the trend in roofing construction that provides long lasting support. It is a pre-assembled frame to hold the roof deck that serves as the crowning skeleton of a building structure. Here is a guide to pick the best roof truss design for certain structures.

Familiarity of roof trusses. The owner has the final say in every construction plan. To end up with a sound decision, it is a must to gather information about roof trusses. Immediate research is only a click away on the internet. There is a variety of materials to scan from illustrations, videos, articles, and blogs.

Expertise from engineers or architects. There are experts on this matter who can give substantial discussions and recommendations. Consult an architect who makes drafts of roofing structures. A structural engineer may also be considered for scholarly opinion. Their ideas yield to the top choices available on roof trusses.

Selection from the roof truss options. There is a variety of roof trusses design to choose from. Its general classification is divided into two such as flat trusses and pitched trusses. Each one corresponds to specific structural layout.

  • Flat trusses. This category is described as such because of its parallel chords namely the top and the bottom. It is simple in structure that there are some variants formed. One is the sloping flat truss. Compared to the typically horizontal flat truss, it is positioned slightly diagonal.
  • Pitched Trusses. This category is referred to as "common truss" since it is frequently used in roofing. It is easily distinguished by the triangular patterns and its steep inclination. Variants of this type include the monopitch and the dual pitch.
  • The monopitch is characterized by a single-winged sloping top chord intersecting a horizontal bottom chord. The dual pitch has two intersecting nonsymmetrical top chords meeting at the separate ends of the horizontal bottom chord.
  • King Post Truss. It is composed of rafters and joist. The rafters are the diagonal chords intersecting at the peak. The joist is the horizontal bottom chord that meets each of the free ends of the rafters. The King Post is the connecting brace between the apex and the joist. It divides the structure into two identical right triangles.
  • Scissor Truss. The top chords are similar to the King Post Truss structure. The only difference is the sloping orientation of the bottom chords forming an obtuse angle under the top frame.
  • Attic, Belgian, Bowstring, Dropped chord, and Howe are also included in the rich list of roof truss types.

Evaluation of the big picture. It is important to look into the grand plan. It involves the harmony between the roof truss design and the building structure. Examine its exterior visual which can readily be scrutinized. Also, inspect the structural feasibility of the total layout design. These dual checks are crucial to meet or even exceed the par in achieving the standard building construction.

With these, all it takes is the construction proper. It is safe to say that it has been thoroughly planned from top to bottom. Raise the roof for a job well done!
