What Are Roof Trusses?

Simply put, roof trusses are engineered components that form the framework of your roof. They’re usually made from wood or metal and consist of interconnected triangles that distribute the weight of the roof evenly across the walls of your home. Think of them as the backbone of your roof, providing support and stability.

Functions of Roof Trusses


Below are a few primary functions of roof trusses.

Structural Support

One of the key functions of roof trusses is to provide structural support to your roof. By distributing the weight of the roof evenly, they help prevent sagging and ensure that your roof can withstand the elements.

Spanning Distance

Roof trusses allow for longer spans between load-bearing walls without the need for internal supports, making them ideal for open floor plans and large living spaces.

Resistance to Forces

They’re designed to withstand various forces, including wind, snow, and seismic loads, ensuring that your roof remains intact during extreme weather conditions.

Flexibility in Design

Roof trusses come in a variety of shapes and sizes, allowing for flexibility in roof design. Whether you prefer a traditional gable roof or a more modern hip roof, there’s a truss design to suit your needs.

5 Types of Roof Trusses

Let’s talk about the 5 common types of roof trusses:

1. King Post Truss

This is one of the simplest truss designs, consisting of a central vertical post (king post) with angled beams extending from it to the top of the roof. While it’s straightforward in design, the king post truss is still effective in providing support for smaller roof spans and structures.

2. Queen Post Truss

Similar to the king post truss, but with two vertical posts (queen posts) for added support and stability. This design variation allows for greater weight distribution and can accommodate larger roof spans compared to the king post truss.

3. Scissor Truss

These trusses have a unique design with bottom chords that cross each other, creating a vaulted ceiling space below. The scissor truss not only adds architectural interest to a space but also provides ample room for decorative ceiling treatments or attic storage.

4. Gambrel Truss

Often used in barns and garages, gambrel trusses have two slopes on each side, allowing for maximum attic space. This design maximizes headroom in the attic while providing a classic barn-like appearance to the structure.

5. Mono Truss

Ideal for small or narrow spaces, mono trusses have a single slope and are commonly used in lean-to roofs or additions. Despite their simple design, mono trusses are efficient in providing structural support while minimizing material usage, making them a cost-effective solution for smaller structures.

4 Benefits of Roof Trusses


Below we cover 4 benefits that roof trusses bring to your roof and home.


Roof trusses are manufactured off-site to precise specifications, reducing labor costs and construction time compared to traditional rafter framing methods. This efficiency not only saves you money during the initial construction but also minimizes potential delays and additional expenses down the line.

Strength and Durability

Engineered to meet stringent building codes and standards, roof trusses offer superior strength and durability, ensuring the longevity of your roof. With proper maintenance, roof trusses can withstand decades of exposure to the elements without compromising their structural integrity.

Ease of Installation

Because they’re prefabricated, roof trusses are relatively easy to install, saving time and hassle during the construction process. This streamlined installation process allows for faster project completion, reducing labor costs and minimizing disruption to your daily life.


From residential homes to commercial buildings, roof trusses can be tailored to suit a wide range of architectural styles and design preferences. Whether you’re building a cozy cottage or a modern office complex, there’s a roof truss design to fit your unique vision and requirements.

Maintaining Your Roof Trusses

While roof trusses are designed to be durable, it’s essential to maintain them regularly to ensure they remain in good condition. Here are a few tips:

Inspect Regularly

Conduct visual inspections of your roof trusses at least once a year to check for signs of damage, such as cracks, splits, or insect infestations. Additionally, after severe weather events like hurricanes or heavy storms, it’s wise to perform an extra inspection to catch any potential issues early on.

Address Issues Promptly

If you notice any problems with your roof trusses, such as sagging or water damage, don’t wait to address them. Prompt repairs can prevent further damage and extend the life of your roof. Remember, a stitch in time saves nine!

Keep Gutters Clear

Clogged gutters can lead to water backup and potential damage to your roof trusses. Keep gutters clear of debris to ensure proper drainage and prevent water from pooling on your roof. Consider installing gutter guards to minimize maintenance and keep water flowing freely away from your home.

Roof Trusses: The Backbone of Your Roof

Roof trusses may not be the most glamorous part of your home, but they play a crucial role in its structural integrity and stability. From providing support and spanning distances to withstanding the forces of nature, roof trusses are undoubtedly critical to keeping your roof overhead and your home safe and sound. So, the next time you look up at your roof, give a nod of appreciation to those trusty trusses holding it all together!
