What is the difference between a roof truss manufacturer and a roof truss agent or broker?

A roof truss manufacturer designs, engineers and fabricates trusses in its own accredited factory — and carries direct liability when something goes wrong. An agent or broker does not manufacture anything. They source from whichever fabricator is cheapest at the time, with no guarantee of accreditation, engineering documentation or accountability. If deflection or failure occurs, agents blame the fabricator while the fabricator disputes liability — leaving you with a structural defect and no clear recourse. When choosing a roof truss supplier in Johannesburg and across Gauteng, ask for ITC SA membership proof, MiTek authorisation and SANS-compliant engineering drawings. Isocraft Truss is a direct manufacturer — one accountable party from design to installation.

What five questions should I ask any roof truss supplier before placing an order?

(1) Are you a direct manufacturer or a broker? A manufacturer carries direct liability. A broker does not. (2) Do you hold ITC SA Category A Fabricator Membership? The highest independently audited certification in South Africa — requires factory inspection, quality audit and verified design capability. (3) Do you produce SANS 10160-compliant engineering drawings upon order? Full working drawings are issued on signed order and design fee payment — your legal record of what was engineered and built. (4) Are you a MiTek Authorised Partner? Confirms certified software, genuine connector plates and trained personnel. (5) Who carries engineering liability if trusses deflect after installation? A confident manufacturer answers this clearly. If the supplier avoids it — that is your answer. Isocraft Truss, your Johannesburg roof truss manufacturer, answers yes to all five.

How do I verify that a roof truss supplier is a genuine accredited manufacturer?

Any supplier can claim to be a manufacturer — here is how to verify it before you commit: Check the ITC SA member register at itcsa.org.za — Isocraft Truss holds COC/849/MIT Category A Fabricator Membership. Verify MiTek partnership — agents cannot hold MiTek authorisation; only direct fabricators qualify. Confirm CIPC registration at cipc.co.za — Isocraft Truss (Pty) Ltd, Reg. 2015/106235/07. Confirm full working drawings are issued upon signed order — a genuine manufacturer provides SANS 10160-compliant engineering drawings on signed order and design fee payment; an agent typically cannot produce compliant drawings at all. Visit the factory — Isocraft Truss operates from 122 Watt Road, Pretoria Industrial, with an active production floor and welcomes verified site visits. If your current supplier cannot satisfy these checks, you have your answer.

What is the real danger of site-made or under-engineered roof trusses?

Roof trusses built on site by unqualified erectors using rule-of-thumb measurements — without structural engineering, SANS 10160 compliance, ITC SA oversight or MiTek connector plates — are fundamentally under-engineered. The failure pattern is predictable: deflection opens gaps in the roof covering, water ingress follows, timber decay accelerates, and structural collapse becomes a matter of time. Every person under that roof is at risk. The attraction is always price — a site-made assembly is cheaper because engineering was skipped. Do your due diligence before you commit. If a price seems too good to be true, there is a reason. As we say in South Africa: "Die koop is deur koop." Isocraft Truss manufactures every truss in a certified factory, to SANS 10160, under ITC SA Category A accreditation — no rule of thumb, no on-site fabrication.

What is the risk when a supplier gives you a subcontractor's number instead of using their own installation team?

When a supplier ends their accountability at the factory gate and hands you a third-party erector's details, they have left you between two parties who share no accountability. If trusses don't fit — the supplier says it is an installation problem. If the erector installs incorrectly — the erector says the trusses are wrong. Your project stalls. Neither party funds the resolution. You do. Isocraft Truss operates an in-house installation team — the same company that designed and manufactured your trusses puts them up. If something needs attention, one phone call resolves it. End-to-end accountability is not a marketing phrase. It is a phone number that answers.

Another supplier told me Isocraft's roof design is not possible. What does this mean?

It almost certainly means that supplier lacks the engineering capability to execute the design — not that the design is structurally invalid. Complex roof geometries, unusual spans, non-standard pitches and compound hip configurations are entirely achievable when designed using professional structural engineering software by a qualified designer, and manufactured by an ITC SA Category A certified fabricator. An unaccredited supplier without certified software, a qualified structural designer, or the production capacity for complex work will encounter designs they cannot replicate. That is a limitation of their process — not a flaw in the engineering. Isocraft Truss designs are produced by our Senior Structural Designer using MiTek engineering software to full SANS 10160 compliance. If a supplier tells you our design is not possible, ask them: "Which SANS standard are you applying, and can you show me the calculation?" If they cannot answer that — you have your answer.
