What Are Roof Trusses?

Roof trusses are prefabricated frameworks made of wood or metal, designed to support the roof’s weight and transfer it to the building’s walls. They consist of interconnected members such as beams, chords, and webs, engineered to distribute the load evenly. Trusses are typically triangular, offering strength and stability to the roof structure.

Advantages of Roof Trusses

Roof trusses offer several advantages over traditional roofing methods that we outline for you below. 

  • Cost-Effective: Roof trusses are often more cost-effective than traditional roof framing methods. Their prefabricated nature reduces construction time and labor costs.
  • Strength and Durability: Trusses are engineered to withstand heavy loads and adverse weather conditions, ensuring the longevity of your roof.
  • Versatility: Trusses can be customized to fit various roof designs and configurations, making them suitable for a wide range of building projects.
  • Ease of Installation: Since trusses are prefabricated off-site, they can be quickly assembled and installed on-site, reducing construction time and disruptions.
  • Space Efficiency: Trusses allow for open, unobstructed interior spaces, providing more flexibility in room layout and design.

Common Types of Roof Trusses

Each type of truss offers unique characteristics suited to different architectural styles and building requirements. We’ll delve into the common types of roof trusses, exploring their designs, features, and applications. Whether you’re planning a new construction or a roof renovation project, understanding these variations will help you make informed decisions to achieve the desired functionality and aesthetic appeal for your property.

  • King Post Truss: One of the simplest truss designs, the king post truss features a central vertical post (king post) with diagonal beams extending from each side to the apex of the roof. This type of truss is renowned for its straightforward construction and suitability for smaller roof spans. While it may not support as much weight as other truss types, its simplicity and cost-effectiveness make it a popular choice for residential buildings and smaller structures.

  • Queen Post Truss: Similar to the king post truss, the queen post truss includes two vertical posts (queen posts) instead of one, offering increased stability and weight-bearing capacity. With its additional support, this truss type is ideal for larger roof spans and structures requiring greater load-bearing capabilities. It is commonly used in residential and commercial buildings.

  • Scissor Truss: The scissor truss is characterized by its inverted V shape, with bottom chords that meet at an angle, making a vaulted ceiling space below. This type of truss is renowned for its aesthetic appeal and ability to maximize interior space. Scissor trusses are often used in residential construction, particularly in rooms requiring cathedral or vaulted ceilings, adding architectural interest while maintaining structural integrity.

  • Gambrel Truss: Commonly used in barns and similar structures, the gambrel truss features two different slopes on each side, providing extra space and headroom in the attic area. With their distinct double-pitched design, gambrel trusses offer increased storage capacity and versatility, making them ideal for agricultural and residential uses. This truss type is also known for its classic barn-like appearance, adding charm and character to any building.

  • Howe Truss: The Howe truss consists of diagonal members in tension and vertical members in compression, offering a strong and efficient roof support system. Known for its versatility and load-bearing capacity, Howe trusses are commonly used in industrial and commercial buildings, as well as residential structures requiring robust roof support. Their balanced design and structural integrity make them suitable for a wide range of uses, ensuring reliable performance in various construction projects.

  • Fan Truss: In a fan truss, the bottom chords fan spread outward from a central point, resembling the shape of a fan. This design allows for a larger open space below the roof. Fan trusses are often used in auditoriums, gymnasiums, and other large-scale structures requiring expansive, unobstructed interior spaces. With their distinctive appearance and ability to support wide roof spans, fan trusses combine functionality with architectural flair.

  • Parallel Chord Truss: Parallel chord trusses feature parallel top and bottom chords connected by diagonal web members, offering a simple yet effective roof support solution. This type of truss is prized for its ease of installation and cost-effectiveness, making it a popular choice for residential and light commercial construction projects. Parallel chord trusses provide reliable support and structural stability, ensuring the safety of the roof system.

Understanding the different types of roof trusses can help you choose the most suitable option for your building project.
