Repeated Leaks
Patch after patch and it's still leaking. Once the underlayment is gone, repairs only buy a little more time.
Rust & Corrosion
Metal roofs with widespread rust, thinning panels or failed fasteners — cosmetic touch-ups won't fix structural weakness.
Extensive Tile Damage
Wide-scale cracked, slipped or missing tiles — when more than 20–30% of the roof is compromised, replacement is the honest answer.
Ageing Timber & Battens
Termite damage, rot or sagging rafters mean the tiles may be the least of the problem. A proper re-roof includes substrate renewal.
After Storm Damage
Major storm events (lifted tiles, torn flashing, punctured sheets) often justify full replacement rather than extended patchwork.
Renovation or Upgrade
Converting a metal roof into a usable balcony, adding skylights or upgrading insulation — all pair naturally with re-roofing.
