About Apex Systems
Marc McMullan founded Apex Systems in 2003 after working his way through every major role in roofing - from installing roofs to selling roofing systems to in-house estimator and leading the National Estimation Team across one of New Zealand's largest longrun suppliers.
Each role built on the last: understanding what happens on-site as an installer and what contractors need as a sales rep. Moving from sales, Marc was asked to establish the in-house estimation role before leading the National Estimation Team across all locations.
When Marc established Apex Systems in 2003, founding client partnerships began that continue today - 22+ years later. Those relationships have been joined by other major New Zealand longrun suppliers and established roofing contractors.
38 years in roofing means understanding the complete picture. Combined with modern digital workflows, that experience translates into professional takeoffs and BOQ services built for long-term business partnerships. When the same clients trust you for over two decades, the service speaks for itself.
