Code of Practice
In 1981, the NZ Metal Roofing Manufacturers Inc. printed the Profiled Metal Roofing Design and Installation Handbook, which set a benchmark for best practice in metal roofing and cladding installation. The handbook was then updated several times, with the most recent update being in 1995.
Two years ago, the group decided to review the Handbook and re-publish it as a Code of Practice. This document is currently before The Department of Building & Housing (formerly the Building Industry Authority (BIA) for possible classification as an acceptable solution to the NZ Building Code.
