A written roof painting quote is your best protection against budget blowouts, substandard work, and disputes down the track. In New Zealand, a thorough quote should spell out every stage of the job — from surface preparation right through to the final coat and clean-up. If a quote is vague or just a single line with a dollar figure, treat that as a red flag.
Why a Detailed Written Quote Matters
Roof painting is a significant investment, and the quality of the prep work is just as important as the paint itself. A detailed quote locks in exactly what you're paying for, makes it easy to compare tradespeople fairly, and gives you legal clarity if something goes wrong. Under the Consumer Guarantees Act, work must be carried out with reasonable care and skill — but you'll have a much stronger position if the scope of work is clearly documented.
The Key Things Every Roof Painting Quote Should Cover
1. Tradesperson Details
- Full business name, physical address, phone number, and email
- GST number (if they're GST-registered — most established businesses are)
- Any relevant trade memberships or certifications
Always check that the person quoting is the person doing the work, or that they clearly state who their crew are.
2. Scope of Work — Preparation
Surface preparation is the most critical part of any roof painting job. A quality quote will detail:
- Whether the roof will be water-blasted (and at what pressure — important for older iron or concrete tiles)
- Treatment for moss, lichen, and mould (e.g. biocide application and dwell time)
- Rust treatment or spot priming on metal roofs
- Repairs to cracked or broken tiles, repointing of ridge caps, or sealing of penetrations
- Whether gutters and downpipes will be masked or protected
Skipping or skimping on prep is the number-one reason roof paint fails prematurely.
3. Paint Products and Specifications
The quote should name the specific paint products to be used, including:
- Brand and product name (e.g. Resene X-200, Dulux Weathershield, or Wattyl Solagard)
- Number of coats (typically a primer/sealer plus one or two topcoats)
- Colour and sheen level
- Estimated coverage rate or total volume of paint to be used
This matters because some contractors quote a low price but use cheap or diluted paint. Knowing the product lets you check the manufacturer's data sheet and confirm it's appropriate for your roof type — whether that's corrugated steel, long-run iron, concrete tiles, or Colorsteel.
4. A Clear Breakdown of Costs
A professional quote should itemise:
- Labour (often the largest cost)
- Materials (paint, primer, biocide, masking, etc.)
- Any hire costs (scaffolding or elevated work platforms)
- GST — shown separately or clearly stated as included
As a rough guide only, roof painting in NZ can range from a few thousand dollars for a small home to well over ten thousand for a large or complex roof — but get at least three quotes to understand the market in your area.
5. Scaffolding and Health & Safety
Working at height is one of the leading causes of serious injury in New Zealand. WorkSafe NZ requires that work at height is properly managed. Your quote should state:
- Whether scaffolding or an elevated work platform (EWP) will be used
- Who is responsible for erecting and removing it
- Any site-specific safety measures
Be very cautious of any contractor who plans to work off ladders only on a steep or high roof.
6. Timeline and Scheduling
- Estimated start date and duration of the job
- Any weather-dependent conditions (paint manufacturers specify minimum temperatures and dry conditions — typically no application below 10°C or in direct rain)
- What happens if the job is delayed due to weather
7. Payment Terms
The quote should clearly state:
- Deposit amount (a reasonable deposit is common; be wary of anyone asking for full payment upfront)
- Progress payment milestones, if applicable
- Final payment due date
- Accepted payment methods
8. Warranties and Guarantees
A reputable roof painter will offer:
- A workmanship warranty (commonly 5–10 years for a quality job)
- Reference to the paint manufacturer's warranty (check the product data sheet)
- What is and isn't covered (e.g. damage from falling branches is typically excluded)
Get any warranty in writing — a verbal promise is very hard to enforce.
9. Variations and Extras
The quote should explain the process if unexpected work is discovered (e.g. hidden rust or damaged sarking). Ideally, the contractor will notify you and get written approval before proceeding with any work outside the original scope.
Comparing Quotes Side by Side
Once you have multiple quotes, use a simple comparison:
| Item | Quote A | Quote B | Quote C |
|---|---|---|---|
| Prep detail | ✓ Full | ✓ Partial | ✗ Vague |
| Paint product named | ✓ | ✓ | ✗ |
| Coats specified | 2 | 2 | Unknown |
| Scaffolding included | ✓ | ✗ | ✗ |
| Workmanship warranty | 7 years | 5 years | None stated |
The cheapest quote is rarely the best value if it's light on detail.
When to Call a Professional
Roof painting itself is not restricted work under the NZ Building Code, but associated tasks can be. If your roof has any penetrations, flashings, or skylights that need resealing, make sure the contractor is competent in this area — poor flashing work can lead to water ingress and costly damage. For anything involving structural repairs, consult a Licensed Building Practitioner. Always confirm with your local council whether any consent is required for associated repair work.
For a quality result, hire a professional roof painter with verifiable experience and references. You can find qualified local roof painters on tradedirectory.co.nz.
