COP v3.0:introduction
View Whole Section for Introduction
The NZ Metal Roof and Wall Cladding Code of Practice (COP) is published by NZ Metal Roofing Manufacturers Inc. (MRM), to provide:
- acceptable trade practice for the fixing of metal roof and wall cladding and accessories.
- prescriptive detailing for designers and sets a benchmark for the standard of detailing and workmanship required over and above that required to comply with the NZBC.
The COP does not describe or dismiss alternative methods, which may need specific acceptance by the Building Consent Authorities.
It is published in accordance with current technology, materials, and building codes. The COP will be periodically updated to reflect changes in legislation and standards or improvements in technology and available materials.
The most current Code of Practice is available on the MRM website, www.metalroofing.org.nz/cop, as Code of Practice Online (MRM COP Version 3).
The latest update on the NZMRM Metal Roof and Wall Cladding Code of Practice was published on 1 June 2021.
In this update COP Clauses 11 Natural Light and 14 Installation were comprehensively reviewed and revised. Users are advised to reread those clauses for the most up-to-date information and recommendations.
Other updates included dividing 4.9.4 Compatibility Table into smaller, more usable clauses and minor fixes to grammar, layout, and updated drawings.
