Director

027 575 7663
With 25 years in the construction industry (much of it as a roofing contractor) Graham founded Rooflogic out of a passion for the trade and a drive to see New Zealand “build better, starting with the right roof.”
Over the past 11 years, Rooflogic has grown from strength to strength, as designers and building owners across the country have embraced the benefits of a well-designed roof: improved thermal performance, effective condensation management, enhanced acoustic control, and carefully selected components to ensure long-term durability.
Graham looks forward to bringing that expertise to your next project, helping designers and specifiers achieve the best possible performance of their warm roof

josh beyer
sales manager
josh@rooflogic.co.nz
027 568 4485
Josh has an in-depth understanding of every Rooflogic system, making him the go-to person for anyone wanting to know exactly how and why our roofs are designed and built the way they are. Equally comfortable in an architect’s office, at RoofLogic’s training facility, or on site alongside contractors with tool belt on, Josh bridges the gap between design intent and practical execution.
A qualified builder by trade, he is well known for arriving at architectural presentations with built samples of roof assemblies and complex details in hand. Architects consistently tell us that the discussions sparked by Josh’s samples are among the most valuable and informative parts of their engagement with Rooflogic.
Josh works closely with Dr Dave on system design and development, driving innovations that are continuing to shape how roofs are constructed across New Zealand.

dr dave
R&D Director
(PhD, CPEng, CMEngNZ, IntPE)
Dr Dave has 30+ years of working experience in the construction industry and is a Chartered engineer, CMEngNZ, IntPE, and APEC Eng. He has a Batchelor Degree in civil engineering and more recently obtained a Doctorate of Philosophy, both from the University of Auckland. Dave’s PhD thesis was entitled ‘Development of Seismic Testing Protocols for Non-Structural Components’, in which he investigated below ground buried infrastructure and above ground building envelopes. He has published several papers in internationally recognised peer reviewed journals, namely ASCE Journal of Pipeline Systems Engineering and Practice, and the Journal of Earthquake Engineering . He has been a committee or technical member for various standards. He is also a peer reviewer for the ASTM Journal of Journal of Pipeline Systems Engineering and Practice.
Dave is an inventor and holds three international patents for building products used not only in NZ but around the world as well. He has been responsible for releasing many products to market over the last thirty years in various different sectors in the building industry. He is currently working on new product lines for Rooflogic.
Dave’s work experience includes practising engineering across New Zealand and Australia.in the following engineering fields; structural, civil, façade, expert witness, technical management and hygrothermal design. His experience covers many industries including; precast concrete, building envelope (including façade and roofs), oil & gas, and building surveying.
Dave heads up the R&D sector for Rooflogic and has his own structural testing laboratory situated in Wellington. The laboratory is equipped with wind uplift testing facilities and other structural testing equipment. Dave also manages testing at outside laboratories when testing is required for specific projects or new innovation products that require specialist testing, such as, fire, structural diaphragm, or hygrothermal properties testing, to name a few.
Dave producers the design calculations for the structural aspects of the Rooflogic systems as well as hygrothermal reports. The hygrothermal work checks that condensation will not be a problem with a Rooflogic solution and can give a comparative analysis between different roof or wall systems to give the client comfort that they have chosen the right system. He is a Producer Statement (PS1) author for B1, which he does when a Rooflogic Alternative Solution is required for a specific project. This service is intended to make the process easier for the client to obtain building consent when an innovative Rooflogic system is chosen. Dave can also provide a PS4 when specifically requested by council as part of their consent conditions, again for B1.
