While most of us may never have heard of roof trusses before, they play a vital role in construction, providing extra layers of strength and security to a building. Suitable for both residential and commercial properties, we’ve compiled this ultimate guide to help you find the perfect match for your project.

What is a roof truss?
- A roof truss is a structural framework designed to provide support for a roof and bridge the space above a room.
Why are there different types of roof trusses?
- Put simply, because there are different types of roofs, there are different types of roof trusses. Made from timber, all trusses have a triangular design, but the shape and/or size of these vary.
- Based on the design of your roof, these differences allow for optimal added strength in areas where it’s needed most.
What are the different types of roof trusses?
Standard fink trusses
- Considered the most common roof truss, a standard fink adds support to a property with extra beams placed in the middle of the internal web (which is a W shape). It is the ideal truss for new buildings and/or extensions as it offers superior strength and stability.
Raised tie trusses
- Made in the same W shape as the standard fink, a raised tie truss creates a slightly smaller baseline for its triangle. This means that it is best suited to create sloping partitions in a room.
- Recognised by their resemblance to the blades of a regular scissor with the addition of beams running parallel to the regular triangular structure, this type of truss is the best fit for naturally sloping ceilings. In domestic buildings, they are used to add strength to the front or master bedrooms.
- There are three variations of attic trusses: cantilevered eaves, standard overhang, and stubbed eaves. Each differs as a result of its shape.
- Cantilevered and standard overhang structures have blocks of timber sectioning off each right angle for added strength.
- True to its name, an overhang structure has elongated sides, marking the only difference between the two.
- Stubbed eaves, on the other hand, feature diagonal pieces of timber within the sectioned-off right angles.
- All are used in properties to transform attic spaces into living or storage areas, providing the extra internal strength necessary to do so safely.
- Built as an isosceles triangle housing added timbered beams inside, all in a triangular shape, mono trusses are used in builds where there is one sloping direction. This makes it ideal for forming new roofs in both commercial and domestic projects.
