Heritage Division
Heritage roofing is a craft, not just a trade.
Combined Roofing Australia’s heritage division specialises in Sydney’s most significant buildings — the slate, lead and copper roofs that most contractors don’t recognise, let alone restore. Heritage work demands a level of care that ordinary roofing simply does not.
From condition assessment through to completion, we breathe new life into a roof while preserving the period detail that makes a building unique — proven across churches, schools, universities and listed buildings, using specialised planning, materials and methods.
What we provide
01
Restoration & re-roofing
Full heritage restoration and complete re-roofs, returned to their original specification.
02
Period-faithful installation
New roofs built to period detail — original profiles, materials and methods, faithfully matched.
03
Lead & copper metalwork
Hand-dressed lead soakers and flashings, copper valleys and rainwater goods, galvanic protection as standard.
04
Repairs & maintenance
Targeted repairs — broken slate, failed bedding, lifted flashings and open joints, identified and fixed.
05
Condition assessment
Drone and on-foot inspections that document every defect before works begin — no surprises on site.
