Is Sarking typically a standard inclusion in an Australian home?

Whether Sarking is standard or an upgrade depends on the builder and their base specification. Volume-builder inclusion packages, project-builder base plans and custom builds all treat it differently. Before signing a contract, ask your builder to confirm in writing whether Sarking is included as standard or is priced as an upgrade.

Sarking explained in detail

The layer of material applied to the underside of a roof or wall that provides an additional layer of insulation and protection from the elements. Made from waterproof and breathable materials, such as a synthetic or natural membrane. Sarking is required under metal roofing in most Australian climates to prevent condensation.
