Erector member companies are expert roof erection companies that have undertaken to ensure that they only erect roofs that have a rational design or are deemed to satisfy with SANS 10400. Erector member companies also ensure that all of their erection teams only erect timber roofs under the supervision of an individual with the South African Qualification Authorities (SAQA) recognised Professional Designation of a Certified Roof Erector. Erector member companies undergo routine independent audits by the ITC-SA or their appointed expert auditor, to ensure that their erections are done in compliance with all applicable Standards and Regulations. All roofs erected by Erector members must be clearly and indelibly marked with a mark that includes their ITC-SA CoC number so as to ensure traceability.
