Restore Your Roof: why repainting a faded or chalky tin roof is a smart move
Australia’s harsh sun, and swings in temperature takes a toll on your roof. If your tin roof looks tired, faded or chalky, repainting isn’t just a cosmetic fix—it’s a practical, value-boosting investment in your property.
Here’s everything you need to know about repainting a faded or chalky tin roof—and why it’s one of the best things you can do for your home or business.
The key aspect is that preventative action now, in repainting your roof, can defer or save significant amounts of money if failure to take action means you have no option but to replace your entire roof.
When Should You Repaint Your Tin Roof?
- The colour is noticeably faded or patchy
- You see white chalky residue on your hands after touching it
- There are signs of surface rust or corrosion, including on screws / fasteners
- The roof is 8–15 years old (or longer) and hasn’t been repainted
- You’re planning to sell or lease and want maximum appeal
Why Tin Roofs Fade or Go Chalky
UV Damage
Constant exposure to the sun breaks down roof coatings, especially older paints that weren’t designed for modern UV loads.
Oxidation
Over time, metal surfaces react with oxygen and moisture, leading to a chalky white residue.
Ageing Paint
All paint degrades eventually. If your roof was painted more than 10 years ago, chances are it’s past its prime. Older paints did not have the same UV resistance and longevity as modern paints.
Environmental Build-up
Dirt, lichen, mould and mildew contribute to fading and paint deterioration.
