Understanding Different Truss Types

When it comes to building a new home or adding onto an existing structure, one of the most important decisions you'll make is choosing the right roof type. There are several different types of roof designs to choose from, each with its own advantages and disadvantages. In this blog, we'll take a closer look at three popular roof types: scissor truss, mono truss, and attic truss, and explain the differences between them.


Scissor Truss


A scissor truss is a type of roof truss that features a unique "V" shape. This design creates a high ceiling in the center of the room, which is ideal for large open spaces like great rooms or living rooms. Scissor trusses are also known for their strength and stability, making them a popular choice for areas with heavy snow loads or high winds.


The scissor truss design allows for a vaulted ceiling, which can add a sense of grandeur and spaciousness to any room. It's important to note, however, that the design of a scissor truss can make it more difficult to install ductwork, lighting fixtures, and other components that typically run through the ceiling.


Mono Truss


A mono truss, also known as a single-pitch or lean-to truss, is a simple roof design that features a single slope. This type of roof is ideal for smaller structures like sheds or garages, or as an addition to an existing building. Mono trusses are typically less expensive to construct than other types of roof designs, and they can be customized to fit a variety of different building styles and sizes.


One of the main advantages of a mono truss is its simplicity. The design of the roof is straightforward and easy to construct, which can help save time and money during the building process. Mono trusses also require less materials than other types of roofs, which can further reduce costs.


Attic Truss


An attic truss is a type of roof truss that features a raised platform or floor in the center of the truss, creating a usable attic space. This design allows for additional living or storage space in the home, which can be especially useful in smaller houses or homes without a basement. Attic trusses are also known for their strength and stability, making them a popular choice for areas with heavy snow loads or high winds.


The additional living space created by an attic truss can be a major advantage for homeowners, especially those with limited square footage. The design of an attic truss can also make it easier to install ductwork, wiring, and other components that typically run through the attic.


Differences Between Scissor, Mono, and Attic Trusses


While each of these roof types has its own advantages and disadvantages, there are several key differences between them. Scissor trusses are designed for large, open spaces and create a vaulted ceiling, while mono trusses are ideal for smaller structures and are simple and easy to construct. Attic trusses, on the other hand, create additional living or storage space and are ideal for smaller homes or homes without a basement.


Another key difference between these roof types is their cost. Scissor trusses are typically more expensive to construct than mono or attic trusses, due to their complex design and the additional materials required. Mono trusses, on the other hand, are typically less expensive due to their simplicity and the lower amount of materials required.


Overall, the right roof type for your building project will depend on a variety of factors, including the size and style of your home, your budget, and your personal preferences. By working with a trusted and experienced roofing contractor or truss manufacturer, you can be sure that you'll receive the guidance and support you need to make the best decision for your unique needs and requirements.
