Where do I find the rules and regs of replacing a roof? Part of the house still has the original 1950s corrugated roof with the old lead nails. It's hanging in there but only just. Wanting to replace and add insulation at the same time. As being a flat roof extension there is no internal access.
Welcome to the Bunnings Workshop community @Brian6. It's terrific to have you join us, and many thanks for your question about replacing a roof.
When replacing a roof, particularly an older one with materials like lead nails, there are several regulations and guidelines you’ll need to follow. The Building Code of Australia (BCA) is the primary source for these regulations, as it outlines the minimum standards for safety, health, and structural integrity in construction. You can access the BCA through the National Construction Code (NCC) on the Australian Building Codes Board (ABCB) website.
In addition to the BCA, you’ll need to check with your local council for any specific regulations or permits required for roof replacement in your area. This is especially important if your property is subject to environmental considerations.
Given the age of the roof, there’s a possibility of asbestos or lead-based materials being present. The handling and disposal of these hazardous materials are strictly regulated, so you may need to engage a licensed professional for safe removal.
If you plan to add insulation during the roof replacement, ensure it meets the required R-value for your climate zone, as specified in the BCA. Furthermore, any work on the roof must comply with Workplace Health and Safety (WHS) standards, particularly regarding fall protection. Safe Work Australia sets these standards, and they may vary depending on your state or territory.
To get started, it’s advisable to contact your local council and consult the ABCB website for detailed guidelines. For older roofs with potential hazards, consulting a professional is strongly recommended.
Please let me know if you have any questions.
