Colorbond and concrete tile cover roughly 90% of Adelaide residential roofs. Which one suits your home? Here's the honest comparison.
Cost
Colorbond is cheaper to install per m2 ($80-$140) than new tile ($70-$170 depending on profile). Restoration is much cheaper than either - so if your tile roof is structurally sound, restoration beats replacement on price alone.
Weight
Tile is roughly 4x the weight of Colorbond. Older Adelaide timber framing (1900s-50s) sometimes struggles with the load - moving to Colorbond reduces structural stress.
Solar readiness
Colorbond integrates much more cleanly with solar panel mounts. If solar is in your near-term plan, Colorbond is the practical choice.
Look
This is the personal preference part. Many Adelaide heritage homes look strange in Colorbond; many modern Adelaide homes look great. Your suburb character matters here.
