Given the many design and statutory requirements for roofing, and the large range of claddings available in today’s market, how do we select the right roofing for a building?

E2/AS1 was updated last year – do you know what changed? This guide has 25 key changes to the design of a building structure and envelope.
A wall or roof underlay is very different from a vapour barrier. One lets moisture through and out of a building and the other doesn’t. Using the wrong one will trap moisture where you don’t want it.
The 6.3 magnitude earthquake that struck Christchurch on 22 February 2011 and the many aftershocks have been an enormous test of the performance of buildings. BRANZ Structural engineers provide some initial thoughts on how houses performed.
The building materials used in roof and wall claddings continue to change over time. What are the current trends?
Steel’s popularity as a structural element is rising, and there’s scope for more use of prefabrication. These are two of the trends BRANZ has identified for commercial building construction.
To simplify the consenting process for structural insulated panels (SIPs), we need to know how they perform locally. A BRANZ research project is helping by examining SIP durability, earthquake and fire performance.
Proper on-site management of roof cladding is critical to delivering quality buildings. This is the final in a series on materials storage requirements and outlines how to store and handle roof claddings.
A recent trip to North America provided opportunities for further refining the BRANZ moisture research programme. Some of the papers presented at a building physics conference are highlighted here.
There is enough information around to make sensible judgements about cladding details as long as you keep four key principles in mind. With these in place, whatever the design, your cladding should be weathertight.
