Yes, you can paint a roof. Metal, concrete tile and terracotta roofs can all be repainted with the right preparation and a coating made for roofs. It can restore a faded roof, protect it from the weather and change how it looks. But roof work is high-risk, and the prep is what decides whether the paint lasts.
Which roofs can be painted
- Metal roofs, including pre-finished and galvanised steel, once cleaned and primed where needed.
- Concrete tiles, after cleaning, repairs and sealing.
- Terracotta tiles, which are often left natural but can be sealed and coated.
If your roof is still under a manufacturer’s warranty, check whether painting affects it before you start.
Why paint a roof
Common reasons include fading, rust, moss and lichen, and wanting a new colour. Heat-reflective coatings are designed to reflect more sunlight than a standard finish, which is worth considering in Brisbane’s heat. A coating also seals the surface and can extend the life of a roof that’s structurally sound.
Preparation is the job
Roof painting is mostly preparation. It usually involves:
- High-pressure cleaning to remove dirt, moss and loose material
- Treating mould and lichen so it doesn’t return
- Repairing cracked or broken tiles and rusted sheets
- Priming or sealing as the product requires
- Applying the coating in the coats and conditions the manufacturer specifies
Get any of this wrong and the paint peels. Our post on how long exterior paint lasts explains what shortens it.
Safety and asbestos
Working on a roof is dangerous. Falls are a major cause of serious injury, and it’s not a DIY job for most people. If the roof or eaves were installed before 2004, they could contain asbestos cement. Don’t sand, scrape or pressure-wash suspect material. Have it tested and handled by a licensed professional first.
Access on larger buildings
On commercial and multi-storey buildings, access shapes the job. Scaffold, elevated platforms and rope access are all used depending on the roofline. See our article on abseiling versus scaffolding for how to choose.
Ask before you paint
Talk to a professional if you’re unsure about the roof’s condition, the material or the coating. See our exterior house painting and exterior commercial painting services, or request a quote.
