What this class covers

ANZSIC class 3223 categorises businesses primarily engaged in specialised roofing installation and treatment services within Australia's construction industry. This classification applies to tradespeople and companies who work on both residential and commercial roofing systems, focusing specifically on the external waterproofing and protective layers of buildings. The class captures operations ranging from complete roof installations to maintenance and recoating work, excluding related activities like plumbing, insulation, or structural carpentry that have their own classifications.

Typical businesses in this category include specialist roof tilers working with concrete, terracotta, or slate materials; metal roof installers fitting Colorbond, zincalume, or custom metal roofing systems; and roofing contractors applying protective coatings, sealants, or waterproofing treatments. Operations might involve new construction projects, roof replacements, restoration work on heritage buildings, or maintenance services for existing structures. The classification is used by government agencies, statistical organisations, and industry bodies to track activity within this specific trade sector across Australia.

Primary activities in plain English

Businesses classified under ANZSIC 3223 typically engage in:

  • Installing and repairing roof tiles made from concrete, terracotta, slate, or similar materials

Practical guidance

When registering your business with the Australian Business Register, you'll typically select ANZSIC 3223 as your primary classification if roofing services constitute your main activity. This classification flows through to your Business Industry Code (BIC) used for tax purposes and annual reporting. Roofing businesses generally fall under high-risk categories for workers' compensation insurance due to the hazardous nature of working at heights - premiums are typically calculated based on wages and the specific risks associated with roofing work.

For grant applications or industry reporting, maintaining consistent classification helps government agencies accurately identify your sector. Some state-based licensing requirements may also reference ANZSIC classifications, particularly for trade licensing and compliance purposes. Keep records demonstrating your primary activities align with this classification in case of review by statistical or regulatory authorities.
