Quick take: After 15 winters on ladders around Queenstown, I can tell you a fresh roof coat is the cheapest insurance you’ll ever buy. Ignore it and alpine UV, frost heave and nor’westers will eat your iron alive.
Why Roof Painting Matters in Queenstown
Queenstown sits at altitude on a lake that funnels four seasons in a day. Summer UV levels rival the Gold Coast while winter nights dip below freezing. That temperature swing makes steel expand and contract, popping the factory coating well before its time. A proper repaint every 8–12 years stops rust before it starts and seals concrete tiles so they don’t crumble.
5 Signs Your Roof Needs Attention
- Chalky surface – rub the iron; if white powder comes off, the top‑coat binder is gone.
- Rust freckles – early orange spots mean the zinc layer is exhausted.
- Flaking paint on ridges – wind hits here first.
- Moss between concrete tiles – holds moisture, then ice splits the tile.
- Faded colour – a sure‑fire SEO term and a real problem. Fading = UV damage.
If you spot any of these, book a roof painter sooner rather than later. Here’s our Roof Painting Queenstown service page with pricing and process details.
The Primers That Survive Queenstown Winters
| Primer | Roof Type | Why It Works in Otago |
|---|---|---|
| Resene Galvo‑Prime | Galvanised & Zincalume | Bites into shiny metal, slows flash‑rust under morning frost |
| Dulux Precision Sealer Binder | Porous concrete tiles | Locks down sandy tile dust before the top‑coat |
| Resene Sureseal | Previously painted iron or mixed‑substrate roofs | Seals flaky edges and equalises porosity |
Prep tip: Pressure‑wash at 3,000 psi, but keep the lance 30 cm off the sheet to avoid forcing water under laps.
Gear & Technique: How We Lay Down a Factory‑Smooth Finish
We run Graco 495 Ultra Max rigs with a 30‑metre hose so the pump stays on the scaffold and never on your lawn. For most iron profiles a 517 tip (0.017") gives the sweet spot between speed and control. Two light passes—north to south, then east to west—beat one heavy pass every day of the week.
Overspray? Not on My Watch
- Mask & mesh: We wrap gutters with 300 µm plastic, then clip shade‑mesh panels over heat pumps and skylights.
- Wind rules: Above 15 km/h we down tools or switch to a roller‑pole on edges.
- Ground covers: Vehicles and veggie beds get 6 × 4 m canvas drop sheets—nothing flimsy.
Fixing Flaking & Rust—Step by Step
- Mechanical remove: Wire‑wheel rust back to bright metal.
- Treat: Flood with Resene Rust‑Arrest.
- Feather‑sand: 120‑grit orbital to lose the edge lip.
- Prime patch: Spot‑prime with Galvo‑Prime.
- Full prime: One full coat over everything.
- Top‑coat ×2: Dry film build of 140 µm total—measured with a gauge, not guessed.
My Go‑To Roof Paints for Queenstown
