Every truss, girder and jack, numbered and positioned on your plan.
Engineered truss designs
Each truss designed for your span, pitch, roof covering and wind conditions.
Bracing details
Top chord, bottom chord and web bracing shown for the erectors to follow.
Working drawings
Issued for approval and for use on site.
A 3D view of your roof
So you and your client can see the roof before it is built.
An itemised quote
Trusses, battens, bracing and fixings, so you can compare like with like.

What we design

From a single carport to a 35 m clear span.

Our designers work on everything from house extensions to schools, churches and warehouses.

Houses and extensions

Gable, hip, valley and multi-pitch roofs for new homes and additions.

Developments

Repeat designs for housing developments, including 200-unit projects.

Long spans

Timber spans up to 18 m routinely, and MiTek Ultra-Span steel for 20 to 35 m.

Attic and room-in-roof

Usable roof space designed in from the start.

Vaulted and raked ceilings

Scissor and raised-tie trusses for height inside.

Exposed feature trusses

Architectural trusses designed to be seen.

How it works

From plans to a buildable roof.

  1. 1

    Send your plans

    Upload them on our plans page, or email or WhatsApp your nearest branch.

  2. 2

    We design the roof

    A designer models the roof on MiTek and checks spans, loads and bracing.

  3. 3

    You get drawings and a quote

    Layout, 3D view and an itemised price, usually within 1 to 5 working days.

  4. 4

    Site measurement

    When your walls reach roof level, a technician confirms dimensions on site.

  5. 5

    Manufacture and delivery

    Trusses are pressed to the design and delivered on our own trucks.

For architects, engineers and QS

Bring us in early.

We advise on, design and cost roof packages at feasibility stage, so the roof is right before tender. Early involvement helps you choose the most economical roof shape, pitch and covering, and avoids redesigns once the walls are up.

Our drawings are produced on MiTek Pamir, the platform engineers and certifiers recognise, and our plants are ITC-SA approved. That makes sign-off by the appointed competent person straightforward. Read more about roof truss regulations and sign-off.

Questions

Roof design: common questions.

Do I pay for the roof design?

No. The roof design, including a 3D view where needed, is free with your quote.

What do you need from me?

Your building plans, ideally with floor plans, sections and elevations, plus the roof covering you want. If the covering is not decided yet, we can advise.

How long does a design and quote take?

Usually 1 to 5 working days, depending on the size of the project and the branch.

Can you design from a sketch?

We can give guidance from a sketch, but a firm quote needs proper plans. Once the walls reach roof level, a technician confirms the dimensions on site before manufacture.

Will my engineer accept your design?

Our designs are produced on MiTek software and our plants are ITC-SA approved, which is what engineers and municipalities expect. Your appointed engineer still signs off the roof.
