In the past, conventional framing techniques were wholly relied on as the main roofing option as they were the only roofing option available. However, the situation has changed. Currently, fewer homeowners are implementing conventional frames. Instead, they are opting for one of the many different types of roof trusses. Roof trusses have grown to be one of the most popular home improvement projects. Their popularity is based on their ease of installation, their flexibility in design, as well as their low overall roof truss prices.

For those who may not know what roof trusses are; these are pre-fabricated roof structures which are carefully manufactured in factories in such a way that they transfer most, if not all, of the load to the house’s external walls. Most types of roof trusses are built at the manufacturer’s site then shipped to the buyer’s location. Later, the roof truss is installed after the walls of the property have been erected.

Types of Roof Trusses

There are a number of  different types of roof trusses currently available in the market. Some tend to be more complex than others. As the design of the roof truss varies in complexity, so does its ease of installation. Typically, complex roof truss designs have additional costs that relate to the increased labor required to implement the design.

The two main basic roof truss designs used in most home buildings are pitch and the parallel chord.

types of roof trussesThe pitch truss, commonly referred to as the common truss, is distinctly recognizable by its unique triangular shape. Though some configuration details may change from one property to the next, the common truss is one of the most used designs when it comes to roof trusses. Such configuration changes include chord size changes and web configurations.




Parallel Truss

The parallel truss, commonly referred to as the flat truss is distinguished from other truss designs by parallel chords located at the top and at the bottom. Due to its design, the parallel roof truss is commonly used to construct floors.

Apart from the parallel and pitch truss, there are a number of different roof trusses. Each has its own unique configuration. Some of the commonly used trusses include arch frame, Pratt Top Chord, as well as Semi Howe and Scissor. Each roof truss has its own individual benefits and drawbacks. Moreover, each is designed to suit a specific house design and if used properly can add to the aesthetic value of the home.

When designing one’s home or remodeling any section that requires roof work, one should consider the overall look of the home before picking a specific type of roof truss. In this way, one can ensure that they pick the best roof truss that adds to the overall value of the home. Moreover, one may have to consider the shape of the roof truss, its size, as well as its complexity in design.

Selecting Specific Types of Roof Trusses

When choosing roof trusses, one will also have to select one that is suitable for their climate. This will mostly depend on the economy of the roof truss material. There are two main materials that may be used in their fabrication: steel roof truss and wood/lumber. Lumber has the best economy as there are no noticeable temperature bridges across the roof truss structure as is common with steel trusses. Moreover, steel trusses tend to have poor insulation when compared to lumber trusses.
