Roof trusses are an integral part of the structure of a building. They provide support to the roof and walls, ensuring that your home is structurally sound. Trusses come in many different styles and designs, so it's essential to understand which type is best for your project and budget.

In this post, we'll have a look at a handful of the most common types of roof trusses to help you make an informed decision on the ideal option for your structure.

Types Of Roof Trusses

Gable roof truss

One of the most basic and popular types of roof trusses is the gable roof truss. These trusses typically have two sloping sides that meet at a peak in the middle. Gable roof trusses are ideal for buildings with a gabled roof because they provide extra support for both roofs and walls.

They could also be used for garages, sheds, and other structures with gabled roofs. As a bonus, gable roof trusses often cost less than other types due to their simple design.

The king post truss

One of the most straightforward and oldest forms of truss designs is the king post truss. It consists of two diagonal beams connecting each side to a central vertical beam called the "king post."

This design is commonly used in small structures such as sheds, garages, and gazebos because it requires fewer materials than other designs and can be constructed quickly and easily.

The queen post truss

The queen post truss is similar in concept to the king post truss. However, it has two additional vertical posts positioned between the king post and each end beam. This adds more stability to the structure and helps distribute weight more evenly across all four corners.

The queen post truss is also often used in small structures like sheds, garages, and gazebos. However, it could also be used in larger structures such as homes or barns where extra strength is needed.

Hip roof truss

Another type of roof truss is the hip roof truss. These are similar to gable roof trusses but have four sloping sides instead of two. Hip roof trusses are great for providing extra stability as they distribute weight across all four sides of the structure rather than just two (as with a gable). This makes them ideal for homes with irregularly shaped roofs or those located in areas prone to high winds or heavy snowfall.

Scissor truss

If you're looking for a unique truss design option for your home or office building, scissor trusses might be worth considering. They have two sloping sides that meet in an inverted V-shape in the centre, creating almost a cathedral effect inside when viewed from below. These trusses are perfect if you want to create an open feeling in your home or office, as they allow more light into interior spaces than traditional flat ceiling designs do.

In addition, scissor trusses offer additional strength due to their unique shape, making them ideal for buildings in areas prone to earthquakes or intense storms, such as hurricanes and tornadoes.

Choosing The Best Roof Truss For Your Home

If you're considering adding a roof truss to your home, several different types are available, and they all have their advantages and disadvantages. To guarantee that you choose the best option for your home, there are some factors that you'll need to consider. Knowing these factors will help you decide which type of truss is best for your needs. These factors include the following:

Material of the truss

The first deciding factor to consider when choosing a type of roof truss is the material of the trusses. Most trusses are constructed from wood or steel, but other materials, such as aluminium, could also be used. Each material has its advantages and disadvantages, so it's vital to understand the pros and cons of each before making a decision.

Wood is strong and relatively inexpensive but requires more maintenance over time than steel or aluminium; steel is durable but more expensive; and aluminium is lightweight and corrosion-resistant but also more expensive than wood or steel. It would be best to consider how much weight your roof can support when selecting a material, as heavier materials might require additional support to be used safely.

Design and shape

Another factor to consider when choosing a type of roof truss is the design and shape of the trusses. Not all types of roof trusses come in standard shapes or designs. Some trusses are designed specifically for certain applications, such as cathedral ceilings or hip roofs.

Additionally, it's essential to consider how the truss will fit with your existing structure's design and shape and any plans you might have for future renovations or additions.

Different roof trusses can provide different levels of strength, flexibility, ease of installation, cost-effectiveness, longevity, and aesthetic appeal, so it's crucial to weigh all these factors before making your final decision.

Additionally, certain building codes might require specific roof trusses to ensure structural integrity and safety, so check with local authorities before deciding what kind of roof truss you'll use in your home.

Cost of installation and maintenance

Finally, when selecting a type of roof truss, it's essential to consider both the cost of installation and ongoing maintenance costs associated with each option. Different types of roof trusses require different amounts of time and labour during installation and varying levels of expertise among installers.

All these should be considered when looking at the overall costs associated with installation. Additionally, some types might require more frequent maintenance than others to preserve structural integrity over time; this, too, should be considered before making a final selection regarding which type will work best for your particular needs and budget.

Benefits Of Using Timber Roof Trusses

Strength and durability

Timber roof trusses are designed to be strong and durable, withstanding the elements better than traditional construction methods. They also offer greater flexibility in design, as they can be customised to suit any particular style.

This makes them ideal for modern architecture as well as more traditional installations. Because of their superior strength and durability, timber roof trusses could last for decades with little or no maintenance required.

Versatility and design options

The versatility of timber roof trusses makes them ideal for any structure or building design. They can be used in both residential and commercial settings with ease and come in various styles and sizes, allowing you to customise your roof frame exactly how you want it without sacrificing strength or durability.

Depending on your desired aesthetic or budget requirements, you could also choose from many different types of materials, such as steel or aluminium.


Timber trusses are highly cost-effective compared to other types of construction materials. This makes them an appealing choice for homeowners looking to build or renovate their homes on a budget. Furthermore, since they are pre-manufactured offsite, there is less time spent on site erecting the structure, which saves money on labour costs too.

Timber trusses also require fewer supporting members than other construction methods, which reduces material costs even further. Finally, since timber is lightweight, there is less need for additional support beams or columns, which further reduces the overall costs.

Less maintenance involved

Another benefit of timber roof trusses is that they require less maintenance than other materials, such as metal or PVC. Wood is naturally durable and resistant to rot, meaning it will last longer without needing repairs or replacements as frequently.

Plus, wood offers good insulation from cold temperatures and fire resistance (which many building codes now require). As long as the wood used is treated correctly with protective sealants or paint, your wooden roof trusses will last for decades with minimal upkeep required.
