STIAN DE JAGER
In 2004, as part of the practical training required to complete his National Diploma in Mechanical Engineering, Stian de Jager completed the Roof Inspector’s Course through Roof Inspection Services (under the tutorship of the late Victor Booth, a Specialist Engineer in Timber Engineering). After his certification, he registered with the ITC-SA as a Qualified Roof Inspector. Whilst completing his Bachelor’s Degree in Mechanical Engineering, de Jager actively worked as a roof inspector and formed De Jager Roofs Business Trust in 2007. A partnership with his grandfather Chris de Jager, who came from a municipal building inspector background to become one of the very first roof inspectors, allowed him to further expand on his roof consultancy experience.
In 2011, Stian was appointed General Manager for Tlhomeso Timbers and Vertex Roofing Contractors, the largest roof truss manufacturers in Botswana. There, while working closely with professional engineers in the timber roof truss industry on, amongst other projects, roof failures and remedials, he furthered his qualifications to include a 20/20 Advanced Designer Certificate from MiTek. In addition, he was mentored by Cor van Os, a pioneer in the roofing industry, often leading system providers in new concepts and management software solutions. In 2012, he was sent to the USA to oversee the rigging and importing of various types of advanced roof truss manufacturing equipment, including the first TCT automated linear saw. His experience eventually led de Jager to consult for MiTek and other South African truss plants on calibration, fault finding and training related to these saws.
De Jager returned to South Africa in 2015 to continue his inspection and consulting work in De Jager Roofs Business Trust. He remains committed to add value and make a significant contribution to the industry through his knowledge, experience and skills. Click HERE to view Stian’s ITC Inspector registration.
