Roof Painting Karori Wellington

Karori is Wellington's largest suburb, and its housing spans almost every era — pre-war corrugated iron villas on the valley floor, mid-century homes with concrete tile roofs on the slopes, and modern Coloursteel builds throughout. Each roof type needs a different approach, and getting that call wrong means you're back on the roof years before you should be. We've painted hundreds of roofs across the area and know exactly what each substrate demands.

Why Choose Our Roof Painting Service

Substrate-Specific Preparation and Products

Iron roofs, concrete tiles, and Coloursteel are three entirely different painting jobs. Corrugated iron needs rust treatment, full scrape-back of any flaking paint, and a rust-inhibiting primer before topcoats go on. Concrete tile is porous and absorbs moisture — surface cleaning and a penetrating sealer are non-negotiable before paint. Coloursteel requires specific primers compatible with the factory-applied coating to ensure adhesion holds. We carry the right products for all three, and we never use a one-size-fits-all approach on this suburb's diverse housing stock.

Valley and Hillside Conditions

Properties in the valley bottom tend to hold more moisture — shaded sections dry slowly, and moss and lichen build up faster than on exposed slopes. Hillside homes face the opposite problem: higher wind exposure accelerates weathering on the windward side. We adjust our prep and product selection based on where your property sits in the valley. A sheltered north-facing roof gets different treatment than an exposed south-facing slope.

Registered Master Painters Standard

Every job is carried out under Registered Master Painters standards. That means documented workmanship, correct film thickness applied per manufacturer specs, and a guarantee you can rely on. We don't cut prep to hit a price — the prep is where the job is won or lost.

Our Roof Painting Process

We follow a consistent process on every roof, adjusted for substrate type:

• Roof inspection — assess substrate condition, identify rust patches, cracked tiles, loose fixings, or failing flashings
• High-pressure wash — remove moss, lichen, dirt, and loose paint. Allow full dry time before coating
• Surface preparation — scrape flaking material, treat rust, spot-prime bare areas, replace any cracked or broken tiles
• Full prime coat — applied to all bare or porous surfaces
• Two topcoats — applied to manufacturer's film thickness with appropriate dry time between coats
• Final inspection — walk the roof before leaving site, address any missed areas

We use Resene roof coating systems throughout — products formulated for New Zealand conditions and proven to hold up in Wellington's climate. We never substitute cheaper products to sharpen a quote — the coating system we specify is the one that will last. See our roof painting service page for full details.

Cost Guide

Roof painting costs depend on roof area, pitch, substrate type, and current condition. As a guide for properties in Karori:

• Small roof (under 120m²): $3,500–$6,000
• Medium roof (120–200m²): $6,000–$10,000
• Large roof (200m²+): $10,000–$18,000

Roofs with heavy rust, significant moss growth, or difficult access will sit toward the upper end. These are guide figures — we provide a written price after a free on-site assessment.

FAQs

How often does a roof need repainting around here?

Most roofs in this part of Wellington need repainting every 10–15 years depending on material and exposure. Valley-floor properties with more shade and moisture may see moss re-establish faster, so a wash-down every few years helps extend the painting cycle.

Can you paint concrete tile roofs?

Yes. Concrete tile is one of the most common roof types in the mid-century housing stock here. The key is proper cleaning and a penetrating sealer to prevent moisture absorption before paint. Done correctly, a painted concrete tile roof holds its finish well.

Do you fix roof issues before painting?

We handle minor repairs as part of the job — cracked tiles, repointing ridge caps, replacing deteriorated flashings. We flag any significant structural issues during the quote so there are no surprises.

What's the difference between roof paint and regular exterior paint?

Roof coatings are formulated for UV resistance, temperature extremes, and water runoff that regular exterior paint isn't rated for. Using the wrong product on a roof is one of the fastest ways to end up with early paint failure.
