Colorbond Vs. Zincalume: NSW Roofing Regulations For Metal Roofs
Coastal suburban areas experience higher corrosion rates, so people living in areas like Cronulla and the Northern Beaches prefer Colorbond roofing. On the other hand, for people living in western Sydney, the BAL rating is more important, and they follow recommendations from the NSW Rural Fire Service. Zincalume roofing uses an aluminium-zinc alloy coating. This solution performs well in inland areas and is ideal for a budget-driven project. It lacks the baked-on colour coat that Colorbond roofing has for durability and thermal efficiency.
