Zincalume Roof Sheets for Heritage Places

Closes 31 Jul 2024

Opened 1 May 2024


In November 2023, the Heritage Council of WA (HCWA) endorsed a revised development guideline for corrugated metal roofs. The guideline outlines acceptable approaches to roof replacement in heritage places to preserve their cultural significance. While the preference is for original roof materials like galvanised iron sheeting, alternative materials such as Zincalume are also considered. 

Principle 3 of the guideline focuses on respecting the heritage place and its elements. Zincalume is identified as an acceptable replacement material in specific instances where the original roof is failing and repair or partial replacement is not feasible. 

We are now seeking feedback from Local Government Organisations (LGOs) across WA on the use of Zincalume and other building materials with reflective surfaces for registered heritage places. Your input is important in ensuring that heritage places are conserved while minimising impacts on local amenity.  

Please share any concerns or suggestions you have by completing the short survey below by Wednesday, 31 July 2024

Your feedback will be presented to the Heritage Council of WA for consideration.
