A faded, chalky or rusting roof drags down the whole building and lets the elements get a foothold. Professional roof painting restores the look and adds years of protection. Goliath Coatings delivers roof painting and restoration across Auckland for tile, metal and Colorsteel roofs — prepared properly and coated to last.
Roof painting is mostly preparation
A roof coating is only as good as the surface under it. Quality roof painting starts with a thorough wash to strip dirt, moss and chalk, followed by treating any rust, rebedding and repointing ridge tiles, and replacing broken tiles or fixings. Skip the prep and the best paint in the world will flake within a season — so this is where most of our time goes.
The right coating for your roof
We use the coating system to the roof type and condition: a sealer or primer to lock down chalky or porous surfaces, then membrane or acrylic topcoats engineered for New Zealand UV and driving rain. The finish renews the colour, sheds water and reflects heat, and on metal roofs it adds a fresh protective layer over treated rust before it spreads.
Protection as well as looks
Roof painting is not just cosmetic. A sound coating keeps moisture out of tile and substrate, slows corrosion on metal, and can lower attic temperatures with reflective pigments. Done well, it postpones a far more expensive re-roof while lifting the appearance and value of the whole property.
The products and systems we use
Recoating a sound roof restores weather protection and looks for a fraction of replacement. On weathered COLORSTEEL and Zincalume we use purpose-made Resene Summit Roof with CoolColour heat-reflective options, gloss Resene Hi-Glo finishes, and self-priming Dulux Roof & Trim. The roof is washed, treated for rust and primed before topcoats go on, so the new system bonds and lasts rather than peeling in a season.

Roof painting FAQs
Q: How long does a roof paint job last?
A: With proper preparation and a quality system, expect roughly 10-15 years before a refresh, depending on roof type and exposure.
Q: Can you paint a rusty metal roof?
A: Yes — we treat and prime the rust first, then coat over it. Catching it early stops the corrosion spreading and saves the roof.
Q: Will roof painting fix my leaks?
A: Painting protects and restores the surface; active leaks need the flashing or membrane fault repaired first, which we assess at quoting.
Q: Can you paint over an old metal roof?
A: Yes, if it’s structurally sound — after washing, rust treatment and priming we recoat with a roof system like Resene Summit Roof or Dulux Roof & Trim, which restores protection and colour without a full re-roof.
