Roof Painting Hataitai Wellington

Hataitai sits in a valley between Mt Victoria and the hills above Evans Bay, and that geography creates a specific set of roof problems. The shade, the damp air, and the way wind funnels through the basin mean moss and lichen grow faster here than in most Wellington suburbs. Add in a housing stock that's largely pre-1940 villas and bungalows with corrugated iron roofs, and you have a situation where regular maintenance isn't optional — it's the difference between a roof that lasts and one that doesn't.

Why Choose Our Roof Painting

Moss and Lichen Treatment That Actually Works

The problem with Hataitai roofs isn't just that things grow on them — it's that a standard wash isn't enough to stop the regrowth. Moss and lichen embed into the surface and a pressure wash alone won't kill the root structure. We apply a biocide treatment after washing and give it time to work before we paint. This kills the organism at the root so regrowth is dramatically slowed. Without this step, you'll be looking at green patches appearing again within twelve to eighteen months.

Experience with Pre-War Iron Roofs

Old corrugated iron requires a different approach to modern roofing. The metal has aged, the profile may have softened in places, and rust can be present even where it isn't immediately visible. We assess carefully, treat rust with a two-part rust converter before priming, and use an oil-based primer on bare or rusted sections before applying topcoat. We don't paint over problems — we fix them first.

Wellington Decorators are Registered Master Painters, which means our tradespeople are qualified, our processes are documented, and our workmanship is guaranteed. Working on older character homes in Hataitai requires care and skill — we bring both.

Our Roof Painting Process

We follow a careful five-step process designed for the conditions Hataitai roofs face. First, a thorough inspection — checking for rust, soft spots, cracked or open laps in the iron, and any areas where water could be pooling under the surface. Second, a high-pressure wash to clear moss, lichen, and loose material. Third, biocide treatment with sufficient dwell time. Fourth, rust treatment and oil-based primer on any bare or corroded sections, followed by a full-surface primer. Fifth, two coats of quality roof paint from Dulux, Resene, or Wattyl — products specifically formulated to withstand New Zealand's UV and moisture exposure. We don't rush the drying time between coats.

Cost Guide

Pricing depends on roof size and the amount of rust treatment and remedial work needed. Pre-war iron roofs often require more prep than modern ones, which affects price. As a general guide: small roofs up to 80m² range from $3,500 to $6,000. Medium roofs from 80–150m² run $6,000 to $10,000. Larger roofs above 150m² are generally $10,000 to $18,000. We'll give you a fixed-price written quote after inspecting the roof — so you know the full cost before we start, not after.

FAQs

The moss comes back every couple of years. Is that normal?

In a valley suburb like Hataitai, some regrowth is expected. But if it's coming back within a year or two, the biocide treatment wasn't applied properly or wasn't given enough dwell time. Our process dramatically extends the time between regrowth.

My roof has rust patches. Can it still be painted?

In most cases, yes. We treat the rust with a converter before priming. If the iron is perforated or structurally compromised, we'll tell you honestly — painting over a failing roof isn't something we do.

What colour should I paint an old villa roof?

Dark greys, deep reds, and heritage greens suit the era well. We can provide colour chips and advise on what works with your weatherboard colour. It's worth spending time on this — a good colour choice lifts the whole property.

How do you handle the valley funnelling wind?

We monitor conditions and won't apply paint on windy days. Paint applied in wind dries too fast, skins unevenly, and doesn't bond properly. We schedule around weather, not in spite of it.
