BACKGROUND
Common roofing materials in New Zealand are asphalt shingles, clay or concrete tiles, membrane, metal(copper/brass, galvanised steel, stainless, zinc/aluminium alloy-coated mind steel, pre-painted steel, corrugated/long-run steel), slate tiles, and timber shingles(ArchiPro, 2020).
The materials listed all have their advantages and disadvantages. The main features differentiating the different materials are durability, weight, waterproofing, and appeal. It is important that the design of the roof takes the local environmental conditions into account. Effective roof design will increase the life of the roof, make it more efficient, and can minimise the cost.
