FREE QUOTEMaybe your home’s had a facelift and that old Pale Eucalypt roof doesn’t quite suit the new style. Or perhaps your Colorbond roof has faded a little over the years, and you’re wondering: can I just paint over it?
The good news? Yes, you can — but only if you do it the right way.
What We’re Covering
In this post, we’ll walk through when and how you can paint Colorbond roofing, the common mistakes to avoid, and whether it’s better to repaint or replace. If you’re a Melbourne homeowner thinking of updating your roof’s look, this one’s for you.
Repainting Colorbond: The Basics
1. Yes, but not with just any paint
Colorbond has a baked-on paint finish that’s designed to last for decades. Standard exterior paint won’t adhere properly to this surface and will likely peel or flake. You’ll need a paint specifically formulated for metal roofing — ideally an acrylic membrane or roof-specific coating.
2. Prep is everything
The roof needs to be thoroughly cleaned and lightly abraded to create a surface that paint can bond to. This often means pressure washing, treating for mildew, and using a metal primer if the original surface is weathered or chalky.
3. DIY? Probably not
While some Melbourne homeowners attempt this themselves, the risks of poor adhesion, streaking, or overspray are high. It’s often best left to professionals who can prep, prime, and spray evenly.
4. Warranty may be affected
Repainting your Colorbond roof may void its original Bluescope warranty — especially if the repaint job leads to corrosion or damage. Always check the fine print or consult with a roofing expert before proceeding.
5. It may not be worth it if the roof is already failing
Painting won’t fix leaks, rust, or structural damage. If your roof is at the end of its lifespan, a full replacement may be the smarter long-term option.
Common Questions from Homeowners
Q: Can I change to a totally different colour (e.g. light to dark)?
Yes, but keep in mind that dark colours may attract more heat. You might also need more than one coat to cover completely.
Q: How long will the new paint job last?
With proper prep and high-quality paint, expect 8–15 years. Not as long as the original Colorbond coating, but decent.
Q: Is it cheaper to repaint or replace?
Repainting is definitely cheaper in the short term. But if your roof has other issues (leaks, rust, damaged sheets), replacement may be more cost-effective long term. You can get an idea of the numbers here: metal roof replacement costs.
Should You Paint or Replace?
If your roof is structurally sound and you just want a visual update, repainting can be a good move — especially if you hire a reputable professional. But if the roof is showing signs of age or damage, investing in a new Colorbond roof may be better value over time.
