A clear, step-by-step look at how a professional roof painting job is done in Auckland — from moss treatment and washing through to primer and topcoats.
A roof repaint is only as good as the process behind it. Skipping steps is the number one reason coatings fail early in Auckland's humid, salty climate. Here is the full professional process we follow, so you know what a thorough job should include.
Step 1 — Inspection & Moss Treatment
We start with an inspection to check for rust, broken tiles, failed fixings and flashing issues. Any moss and lichen is treated with a biocide and left to die back. Treating moss first stops it regrowing under the new paint. See our moss treatment service for how this works.
Step 2 — Washing & Repairs
The roof is then water-blasted to remove dead moss, chalk and dirt, exposing a clean surface. We carry out repairs — re-fixing sheets, replacing cracked tiles, and treating rust spots. A repaint is the right time to fix small issues found by our roof repair team before they are sealed under paint.
Step 3 — Priming
Bare metal, rust-treated areas and porous surfaces are primed with the correct product. Priming is what gives the topcoats something durable to bond to. Skipping primer is a common shortcut that causes early peeling, as covered in our paint peeling causes guide.
Step 4 — Topcoats & Final Check
Two topcoats are applied, usually by airless spray for an even finish, with attention to laps, ridges and edges. We then do a final walk-over and clean up. You receive a tidy site and a roof finished in your chosen colour with a workmanship guarantee.
Frequently Asked Questions
How long does it take to paint a roof in Auckland?
Most homes take 2–4 days depending on size, weather windows and how much repair and moss treatment is needed.
Do you treat moss before painting?
Yes — moss is treated first and allowed to die back, otherwise it regrows under the new coat and causes peeling.
Can roofs be painted in winter in Auckland?
Painting needs dry surfaces and suitable temperatures, so winter work depends on weather windows. We schedule around forecasts.
What paint do you use?
We use proven roof coating systems suited to NZ steel and tile, matched to your roof type and chosen colour.
