How much will my roof trusses cost? (Roof Truss Pricing)

Timber roof trusses, also known as trussed rafters, are one of the most critical considerations in any residential building project. Before these are designed and ordered, the type of truss required needs to be identified as there are many different options available. When it comes to pricing roof trusses, the original roof truss design, as well as the span and pitch can influence costs depending on the size of the project. 

If you’ve been wondering how much the required roof trusses will cost for your project, we have the answer. With our new instant quote function, you can get a quick indicative quote for your roof truss configurations in just four simple steps.

The cost of your roof trusses will depend on various factors. To get an accurate quote for roof trusses, you will need to have the following details before you start the process:

  • Truss type: this depends on the roof shape
  • Span (mm): refers to the distance across the length of the truss where it bears onto the wall supports.
  • The pitch (degrees): is the angle of the top chord of the truss as it runs away from the wall head.
  • The quantity: how many trusses required for the roof space or project in general

 

What truss options are available? (Main types of Trusses)

  • 35mm standard roof truss: the standard roof truss used for the majority of new build houses across the UK. These trusses can also be used for garages and extensions, as well as self-build projects.
  • Attic standard overhang: these trusses are used when habitable space is required within the room zone. These trusses are designed as attic style with larger sections of timber to support additional loadings which allow people to live within the truss zone.
  • Attic standard overhang, attic cantilevered eaves and attic stubbed eaves all refer to the end detail of the truss only, where the trusses bear onto the wall heads.
  • 35mm mono: these are sloped in one direction and often used in porches and for hip end.

The cost of roof trusses:

For a 64m2 house which is a standard 3-bedroom new build, you would need 14no 35mm standard roof trusses with a span of 8000mm with a pitch of 35 degrees. A project of this nature would typically cost £982.80, as indicated by our roof truss instant quote estimator below:

For the same project, but instead, with attic – cantilevered eaves trusses, this would cost £2, 866.50.

Factors that can affect the cost:

Several different factors can affect the cost of roof trusses, that is why it is important to budget for them at the project planning phase. For example, the complexity of the trusses required and also the space between the trusses, when installed, will affect the cost. Our truss designs are quoted based on 600mm centre to centre spacing wherever possible, but if this was to be decreased due to additional loads such as underfloor heating, more trusses would be required for the overall area and would, therefore, raise the total cost to support the weight. Also, if the truss span is over 12 metres, then it would require heavy timbers as per building codes, and this again would affect the cost significantly.

For most projects, whether you are a self-builder or contractor, the price will be an important factor. Our Instant quote calculator will help to give you an indication of the cost of the manufacture and supply of roof trusses for the project.

If in doubt, our team of designers have extensive experience in advising on any project and would be more than happy to guide you during your project. The cases above are just a few examples of the types of trusses we can design and supply. For more complex projects, our designers are on hand to provide guidance.
