What Type of Timber Roof Truss Design Can You Use in Your Home?

A roof truss system refers to a framework of timbers that are used to provide support and stability to a roof and its coverings. The structure disperses the weight of the roof from the exterior walls to prevent structural instability. Timber is one of the commonly used materials for the construction of roof trusses. The construction of timber trusses involves joining two or more pieces of wood using wood to wood joinery.

There are two common roof truss designs, and the best design for your home will depend on the following factors:

  • The size of open spaces within the building
  • Weather conditions experienced in the area
  • Aesthetic expectations from the truss design

Roof trusses are often prefabricated and delivered on site, and this eliminates human error, saves construction time, and saves on labor costs. Here are some of the timber roof truss systems that you can choose to achieve the desired structural stability and aesthetics in your home.

Pitched roof trusses

Pitched truss design is the most commonly used design in the construction of timber roof trusses. The design is characterized by a triangular shape whereby there are two angled sides which meet in the middle. Both sides have gables at the end. In the conventional pitched design, the two pitches have the same angle of pitch, but in some modern designs, one pitch may be angled lower than the other for aesthetic purposes.

The angle of pitch is usually determined by various aesthetic and climatic factors. For example, if you want to install solar panels for maximum solar gain, you may want to orient the pitches for this purpose. Also, some people create a deep pitch to prevent accumulation of snow on the roof during winter. The angle of the pitch can determine the look and feel of the entire house.

Flat roof trusses

Flat or parallel truss design is commonly used in the construction of floors and large buildings such as malls and warehouses; however, this does not mean that you cannot use the design for your roof construction. Homes that take a country, traditional or rustic design are most suited for flat truss design.

Flat roof trusses are preferred for their snow catching ability. Accumulated snow on the roof during winter acts as insulation and reduces heating costs in the home. Also, these roofs can be built low and blend in with the surrounding seamlessly, giving the hoe's exterior a natural feel. Another benefit of flat trusses is that you can create a green roof by having synthetic grass on it to add to the natural look.

Timber roof trusses are increasingly becoming popular in residential and commercial buildings. You can tweak these truss designs and customize them to come up with a roof truss system that complements your home and brings out your personal style.
