Stick frame roofs have been a staple in construction for centuries, but they're not the only option. They're made by notching the ends of rafters to fit together with the top plate of the wall, creating a sturdy structure.
One of the key benefits of stick frame roofs is their flexibility. They can be easily modified or repaired, making them a great choice for DIY projects or renovations.
However, stick frame roofs have a few drawbacks. They can be more time-consuming to build, requiring more labor and materials.
Stick frame roofs are also more prone to sagging, especially if the rafters aren't properly notched or spaced. This can lead to structural issues down the line.

Stick Frame Roof
A stick frame roof, also known as rafter roofing, consists of individual rafters that connect to a top beam, creating an open, triangular shape between the ceiling joists and rafters.
This method is ideal for rooms with cathedral ceilings or homes with attic or storage space, as it allows for easy access to the bottom of the roof and makes it easier to change or modify the roof in the future.
Stick frame roofs can be more time-consuming to build than trusses, but they offer more flexibility and can be used for any building location, making them a good option for remote or hard-to-reach sites.
Here are some key advantages and disadvantages of stick frame roofs:
- Advant
- Maximize open area for vaulted ceiling
- Time savings by avoiding time spent waiting on engineering, drawing plans, and manufacturing
- No heavy machinery required for delivery or installation
- Easier to change or modify in the future
- Uncover problems easier due to easy access to bottom of roof
- Disadvant
- Stick roofs are not as steady as a truss roof
- More material waste, and potential for additional waste if a rafter is not cut correctly.
- Often require more maintenance than a truss roof
- Most specialty ceilings can be accomplished with trusses
What Is a Rafter?
A rafter is a type of framing member used in construction to maximize space in a structure.
Rafters are commonly used in pole barns to achieve steeply vaulted ceilings or extra storage clearance.
They can be single or double-ply, and use only one framing member - no bottom chord or webbing.
Rafters can be used as the primary structure, but if you do, you'll need additional headers or interior supports.
You can use rafters as an alternative to traditional trusses, but keep in mind the potential need for extra support.
Rafters vs. Joists
A stick-framed roof relies on individual rafters to connect to a top beam, but what exactly is a rafter? In simple terms, a rafter is a board that spans from the ridge to the top of the exterior wall.

Rafters are typically cut and constructed on-site, which can make installation quicker and help keep costs down. They're commonly made using 2x8s, 2x10s, and 2x12s, making them stronger than trusses.
On the other hand, joists are not specifically mentioned in the context of stick-framed roofs, but rather, the article mentions ceiling joists and purlins (horizontal beams) that link the rafters. This technique provides support and helps distribute the weight of the roof.
Here are some key differences between rafters and trusses:
- Material: Rafters are stronger and made with thicker boards (2x8s, 2x10s, and 2x12s), while trusses use 2x4s.
- Construction: Rafters are cut and constructed on-site, while trusses are prefabricated off-site.
- Support: Rafters rely on purlins and ceiling joists for support, while trusses form a webbed pattern.
- Installation: Rafters can be installed quicker on-site, while trusses require more planning and engineering.
What Is a Pole Barn?
A pole barn is a type of building that uses a post frame construction method. This method relies on trusses to support the roof, which are comprised of a top chord, a bottom chord, and webs connected at the joints with plates.
Trusses are a rigid framework of wooden members designed to support a roof, making them a crucial component of pole barns. The actual truss profile, spacing, span, heel height, pitch, overhang, and web configuration will vary by application.

The post frame construction method allows for a more open interior space, which is ideal for pole barns. This is because rafters will affect the overall layout of your building, making them less suitable for this type of construction.
The use of trusses in pole barns provides a strong and stable roof structure.
Truss Roof
A truss roof is a great option for homeowners who want a durable and cost-effective solution. Trusses are prefabricated in a factory and delivered to the construction site, making them lighter and easier to install than stick-framed roofs.
One of the main advantages of truss roofs is their stability and durability. Trusses are engineered to provide similar or better strength than stick-framed roofs, yet they use less materials.
Trusses are also more cost-effective, especially for complex roof designs. However, they may require additional time and resources for engineering and manufacturing.
Here are some key benefits of truss roofs:
- More cost-effective (depends on the complexity of the roof)
- Lighter, easier to install, and less maintenance
- More durable and stable than stick-framed roof
- Additional insulation can be installed to better cool or heat home
Despite their benefits, truss roofs may require heavy machinery for delivery and installation. They can also be more difficult to renovate, especially if there is no storage space.
Stick Roof vs Truss
Trusses provide structural protection for the building, supporting water drainage and runoff, and serving as the first line of defense against falling debris.
Trusses are designed to support roofing materials, but their strength is also crucial in the event of a large branch or tree falling on the house.
In contrast, stick roofs rely on individual rafters to support the roof, which can be more prone to damage from water and falling objects.
Rafters, like trusses, provide structural support, but their design should also accommodate water drainage and runoff to prevent damage to the roof and building.
If you're considering a stick roof, you'll need to ensure that your rafters are designed to handle the weight of the roof and any potential falling debris.
Pros and Cons
Stick framing and trusses are two popular options for building a roof, each with its own set of benefits and drawbacks. Stick framing is beneficial for remote areas where shipping prefabricated trusses can be challenging, and it allows for easier plan changes and adjustments.
Stick framing also enables the construction of complicated roofs with multiple gables or steep pitches, and it allows for vaulted ceilings and attic space. However, it can be more labor-intensive and costly, and it requires more on-site work, making it vulnerable to weather-related delays and accidents.
Here are some key differences between stick framing and trusses:
Ultimately, the choice between stick framing and trusses depends on your specific needs, budget, and timeline.
Advantages of Rafters
Rafters are a tried-and-true method of construction that has its own set of advantages. They can be used for any building location, making them a great option for remote or hard-to-reach spots.
One of the benefits of rafters is that they don't require as much front-loaded planning. This is because they are typically built on-site, eliminating the need to order and transport them like trusses.
Rafters also provide more space in the home, which can be a huge plus for homeowners. This is because they allow for a more open and airy feel, making it easier to convert the attic into a living space down the road.
Proper attic insulation is key to keeping energy costs down and maintaining a comfortable living space. Installing adequate insulation is much easier with rafters than with trusses.
Here are some of the key advantages of rafters at a glance:
- Can be used for any building location
- Don't require as much front-loaded planning
- Allow more space in the home
- Insulation is easier to install
Pros and Cons
Trusses have become increasingly popular in the United States due to their quick installation and lower price tag compared to rafters. Trusses are often more cost-effective than rafters, with prefabricated truss packs being less expensive to purchase than installing rafters.
One of the main advantages of trusses is their ability to provide greater span and superior strength. Trusses can reach up to 60 feet in span, compared to the 30-foot limit of rafters. This makes trusses a better option for larger buildings or those with complex roof designs.
Trusses are also prefabricated in a controlled environment, which reduces the potential for human error and increases accuracy. This can lead to faster framing once the materials are on-site, which is a significant advantage for builders who are concerned about weather or other factors impacting the build.
However, trusses do have some drawbacks. They can be less flexible than rafters, making it difficult to make alterations or modifications once they are installed. Trusses also require delivery and associated shipping costs, which can add to their overall expense.
Here are some key differences between trusses and rafters:
In summary, trusses offer several advantages over rafters, including greater span and strength, faster installation, and lower costs. However, they also have some drawbacks, such as less flexibility and higher shipping costs. Ultimately, the choice between trusses and rafters will depend on the specific needs and requirements of the project.
Materials and Potential
Trusses are consistently built using 2 x 4s, making them a standardized and prefabricated option.
Rafters, on the other hand, can be made from a variety of board sizes, ranging from standard 2x4s to wider dimensional boards like 2x8s and 2x10s.
The larger sizes of rafters allow for more room within a design, perfect for vaulted ceilings.
However, rafters are better suited for smaller structures due to their limited ability to support heavy loads over extended spans.
Trusses, with their webbing approach, can provide support over wider or longer spans, making them a popular choice for larger homes.
