David Smith St Ives Roof Trusses have been designing and manufacturing roof trusses in conjunction with Gang Nail® Systems for over 25 years. This longstanding relationship ensures that we are at the forefront of the industry, and enables us to access the latest technology when developing roof solutions for our customers.

Supplying a wide range of customers from National House Builders to DIY enthusiasts, we have a wealth of experience and expertise in developing the very best roof  solutions for your needs.

David Smith St Ives Roof Trusses are committed to quality and we pride ourselves on our long-serving local workforce; it is through them that we are able to produce consistent quality time and time again.

Our trussed rafters are produced to CE mark requirements and manufactured to meet ISO 9001 quality assurance. We closely monitor our suppliers to ensure that we are only using the best quality material from regulated sustainable sources. We are FSC® and PEFC Chain of Custody certified and comply with the requirements of the EU Timber Regulations (EUTR).

We are a member of the Trussed Rafter Association (TRA), the trade body responsible for the UK trussed rafter industry, and work closely with them in their commitment to improving standards of quality, service and safety.


With a large design team we are able to offer a quick response time, whether resolving technical issues, producing drawings for sites, or providing quotations.

We work closely with architects, engineers and surveyors to provide full roof solutions, helping to identify potential issues before they become a reality and endeavouring to ensure that the customer always receives the most cost-effective solution.

With our technical expertise, we are always willing to assist in feasibility studies of new roof proposals, and help many architects and engineers in this way.

Whilst the core of our work is with National House Builders, we often demonstrate our capabilities and innovation on specialist, one-off projects such as care homes, apartment blocks, schools and hospitals. We produce clear, comprehensive and precise design drawings to facilitate the efficient erection of our trusses.

We appreciate the importance of the local builder and self-build market, and use our extensive experience to guide and assist when tackling complex conversions, renovations or simple extensions. We have dedicated meeting rooms and always welcome those who wish to discuss their requirements in person.

On larger projects, we also offer an installation service, using a team of highly skilled experienced carpenters who install efficiently to a high standard of workmanship.

Attic trusses have proved a popular and cost-effective solution to gain extra habitable or storage space within the roof of a project. They offer maximum returns to the developer, house builder and homeowner, without increasing the footprint of a project.

David Smith St Ives Ltd have extensive experience in providing ‘Room in Roof’ solutions. Whether this be with Attic Trusses, Lattice Trusses, Space-Rafters, or Glulam Beams, our technical team will work with you to develop the best solution for you.

Using the latest 3D Gang Nail® design software, we can show customers visualisations of the design proposal and clearly highlight any issues that may be faced. Working with our Staircase department, we can also ensure that the correct apertures are allowed for practical staircases.

spandrel panels

Factory-clad, timber-frame spandrel panels offer significant time and cost savings in replacing the need for blockwork within the roof space above the ceiling line.

Manufactured to the profile of the roof, they conform to current building regulations for fire and acoustic performance, but can be tailored to your needs should enhanced performance be required.

Delivered pre-slung and with a protective membrane to resist the elements, they offer considerable Health and Safety advantages over a more conventional build, whilst also enabling buildings to become water-tight faster.

Our modern manufacturing unit enables us to produce high volumes of trusses efficiently and accurately. With four hydraulic presses and a state of the art multi-bladed CNC saw, we are capable of making in excess of 1,500 trusses a week.

The factory’s purpose-built nature provides us with the flexibility to produce trusses of heights and spans that are beyond the capabilities of many of our competitors. Spans in excess of 15 metres or heights in excess of 4.6 metres are possible and with the CNC resources available across the company; we truly can make trusses of all shapes and sizes!

Our on-site timber treatment plant gives us the flexibility to react quickly to our customers’ needs, whilst ensuring that we are in control of this environmentally sensitive aspect as we specify only water-borne, organic preservation treatment.


David Smith St Ives Roof Trusses offer nationwide coverage. Using a combination of our own delivery vehicles and trusted outside hauliers, we pride ourselves on our flexibility to meet our customers’ ever-changing needs.

All our drivers are trained to the latest standards in site safety and handling to ensure that not only does your product reach you in pristine condition, but your operatives are instructed to unload products in a correct and safe manner. Furthermore, we offer a factory-fitted sling service, facilitating the safe craning of trusses direct from our delivery vehicle.
