Barn style roof trusses have become increasingly popular in both residential and commercial construction due to their aesthetic appeal, durability, and cost-effectiveness. This guide will provide you with everything you need to know about barn style roof trusses, including their benefits, types, installation, and cost.

Benefits of Barn Style Roof Trusses

• Aesthetically Pleasing: Barn style roof trusses add a touch of rustic charm to any building. They are especially popular in rural and farmhouse-style homes.
• Durable: Roof trusses are engineered to withstand heavy loads and extreme weather conditions, making them ideal for areas prone to high winds and snow.
• Cost-Effective: Roof trusses are typically less expensive than traditional stick-framing methods, as they require less labor and materials.
• Energy-Efficient: The open design of roof trusses allows for proper ventilation, which can help to reduce energy costs.
• Versatile: Barn style roof trusses can be used in a variety of applications, including homes, barns, garages, and commercial buildings.

Types of Barn Style Roof Trusses

There are several different types of barn style roof trusses available, each with its own unique advantages and disadvantages.

• King Post Truss: This is the most common type of barn style roof truss. It features a single central king post that supports the ridge beam. King post trusses are ideal for small to medium-sized buildings.
• Queen Post Truss: Similar to the king post truss, the queen post truss has a central post that supports the ridge beam. However, the queen post truss has two additional posts that support the bottom chord. This type of truss is suitable for larger buildings.
• Scissor Truss: This truss has a unique X-shaped design. Scissor trusses are often used in buildings with high ceilings or steep roofs.
• Gambrel Truss: This truss has a curved bottom chord and a flat top chord. Gambrel trusses are popular in barns and other agricultural buildings.

Installation of Barn Style Roof Trusses

The installation of barn style roof trusses is a complex process that should be performed by a qualified contractor. The following steps are involved in the installation process:

1. Design the Truss System: The first step is to design the truss system based on the specific requirements of the building. This includes determining the size, shape, and spacing of the trusses.
2. Manufacture the Trusses: The trusses are then manufactured in a factory setting. This ensures that they are built to precise specifications.
3. Deliver and Install the Trusses: The trusses are delivered to the job site and installed on the roof framing. This is typically done using a crane.
4. Bracing the Trusses: Once the trusses are installed, they must be braced to ensure stability. This is done using temporary bracing, which is removed once the roof deck is installed.
5. Installing the Roof Decking: The roof decking is then installed over the trusses. This decking provides a solid surface for the roofing materials.
6. Installing the Roofing Materials: The final step is to install the roofing materials, such as shingles, tiles, or metal panels.

Cost of Barn Style Roof Trusses

The cost of barn style roof trusses varies depending on the size, shape, and complexity of the trusses. However, as a general rule of thumb, you can expect to pay between $5 and $10 per square foot for roof trusses.
