Why checking a roof painter matters
Roof painting is more than just adding a fresh coat of colour. A good job can improve weather protection, slow corrosion, and extend the life of the roof, especially in NZ’s harsh UV, coastal salt air, wind, and high rainfall areas. A poor job, on the other hand, can fail early, leave rust untreated, or even make leaks worse.
The tricky part is that roof painters in New Zealand are not usually part of a single mandatory licensing board in the same way electricians or plumbers are. That means it is up to you to check their experience, training, and business credentials before you hire.
In practice, the right roof painter should be able to show:
- relevant painting and surface-preparation experience - safe access and working-at-heights knowledge - suitable insurance - references and examples of similar roof work - clear written pricing and scope
If the job involves other trades, such as electrical work for solar panels, or structural repairs before painting, those trades may need their own licensed professionals.
Is roof painting a licensed trade in NZ?
Usually, no. Roof painting itself is not a “restricted work” trade under the same system used for plumbing, gasfitting, drainlaying or electrical work. There is no universal national licence that every roof painter must hold just to paint roofs.
That said, some related work can trigger other rules:
- **Electrical work**: If light fittings, aerials, solar panels, wiring, or roof-mounted electrical components need removal or adjustment, a **licensed electrician** may be required. - **Plumbing or gasfitting**: If your roof work overlaps with venting, flues, or other plumbing/gasfitting components, those trades may need registered, licensed practitioners. - **Building work and consent**: Roof painting alone usually does not require a building consent. But if the job includes roof repairs, replacement of sheets, structural repair, or changes to roofing systems, you may need to check with your local council.
So while the painter may not need a statutory licence, you should still verify qualifications, safety systems, and business legitimacy.
What qualifications should a roof painter have?
There is no single must-have qualification, but several are good signs of competence.
Look for a contractor who has one or more of the following:
- a trade qualification in painting and decorating - training in roof coating systems and surface preparation - manufacturer training for the coating product they are using - experience with the specific roof type: decramastic, Colorsteel, long-run iron, concrete tile, metal tile, or membrane roofs - working at heights training - asbestos awareness training if older roofs are involved
A painter who understands roof materials is important because preparation methods vary a lot. For example, a concrete tile roof needs a different clean, repair and primer process from a rusted metal roof or a previously coated membrane.
Ask what training they have done recently, not just years ago. Roof coatings, safety gear and product systems change over time.
How to check their credentials properly
Use a simple, step-by-step check before you accept a quote.
| What to check | What to ask for | Why it matters | |---|---|---| | Business details | Full legal business name, NZBN if available, physical address, phone and email | Helps confirm they are a real, traceable business | | Experience | Photos of completed roof jobs, references, examples of your roof type | Roof painting is highly surface-specific | | Training | Certificates for painting, coatings, or working at heights | Indicates they understand proper methods and safety | | Insurance | Current public liability insurance certificate and, if relevant, contract works cover | Protects you if they cause damage or injury | | Product knowledge | Brand, primer, topcoat system, and warranty details | Ensures the coating matches the roof material and condition | | Safety practices | Edge protection, harness use, access equipment, fall-arrest systems | Working at heights is a major hazard | | Compliance | Can they explain whether council consent or other trades are needed? | Avoids illegal or incomplete work |
You can also check whether the company is registered for GST and has a proper invoice process. That is not a licence, but it is a useful sign that the business is established.
How to verify a contractor in NZ
Because roof painters are generally not licensed through a dedicated statutory board, verification is mostly about checking business and trade evidence carefully.
1) Confirm they are actually trading in NZ
Ask for:
- the full company or trading name - a GST number if they are GST-registered - an invoice with their legal details - references from recent NZ customers
You can also search the company name online and check the **Companies Register** if they claim to operate as a company.
2) Ask for proof of insurance
Roof work is risky. Ask for a current certificate showing:
- public liability insurance - the amount of cover - the policy dates - the insured business name
If the painter is a sole trader, they still need insurance. Do not assume a small operator is covered automatically.
3) Check references and photos carefully
Ask for jobs completed in the last 6–12 months, ideally on a similar roof. Good questions include:
- Did they remove moss, lichen, rust or flaky old paint properly? - Was the roof cleaned and primed? - Did the finish hold up after winter or a hot summer? - Were gutters, paths and landscaping protected? - Did they leave the site tidy?
If possible, ask for a contactable reference from a recent customer.
4) Confirm they understand working at heights
In NZ, falling from roofs is a serious hazard. A credible roof painter should be able to explain how they manage it, including:
- roof edge protection or scaffolding where required - harnesses and anchor points - safe ladder use - weather checks before starting - site exclusion zones for people below
If they seem casual about safety, that is a red flag.
When do consent or other rules come into play?
Roof painting itself usually does not need a building consent. However, the wider job might.
You should ask whether any of these apply:
- **Roof replacement or major structural repair**: may need council consent depending on scope - **Asbestos-containing roofing**: should be handled with care, and sometimes by specialists - **Solar panel removal/reinstatement**: may require an electrician and other certified trades - **Flues, vents or chimney-related work**: may involve additional compliance - **Leaky or damaged roof repairs**: may require building knowledge beyond painting alone
If the painter says consent is definitely not needed, ask them to explain why. For anything beyond straightforward repainting, it is worth confirming with your local council.
Red flags to watch for
Be cautious if a roof painter:
- refuses to provide a written quote - cannot name the exact paint system they will use - gives a very low price without explaining prep work - says they do not need insurance - avoids discussing heights safety - cannot show photos or references from similar jobs - pressures you to pay a large deposit upfront in cash - says they can do roofing repairs they clearly are not qualified for - dismisses council consent questions without explanation
A cheap quote can be expensive later if the coating fails early or roof damage is missed.
What a good written quote should include
Always get at least two or three written quotes. A proper roof-painting quote should spell out:
- roof type and approximate area - washing and surface preparation method - treatment for moss, mould, lichen or rust - repairs included and excluded - primer and topcoat brand/system - number of coats - access method and safety setup - start date and estimated duration - weather delay policy - warranty length and what it covers - GST inclusion
If a quote is vague, ask for clarification before you sign anything.
Why experience with NZ conditions matters
NZ roofs face some tough conditions. In many parts of the country, the painter needs to factor in:
- strong UV exposure in summer - frequent rain and fast-changing weather - coastal corrosion in salty air - moss and lichen growth in damp or shady areas - wind that can affect overspray and access
A painter who works in Auckland may need different product choices than one in Dunedin, Tauranga, Napier or Queenstown. Local experience matters because the same roof material can perform very differently depending on climate and exposure.
Ask what they would recommend for your area and why. A professional should explain product choice in plain language, not just push the most expensive option.
Questions to ask before you hire
Use these questions to separate professionals from cowboys:
- How many roofs like mine have you painted in the last year? - What preparation will you do before coating? - What coating system are you recommending, and why? - Do you have current public liability insurance? - How do you manage safety at height? - Will you check for rust, loose screws, cracked tiles or damaged flashing before painting? - Do you use subcontractors, and if so, are they qualified and insured? - What is excluded from the quote? - What happens if bad weather delays the job? - What warranty do you provide, and what voids it?
If they answer clearly and confidently, that is a good sign.
Final checklist before you sign
Before accepting a roof painter, make sure you have:
- at least two written quotes - proof of insurance - references or photos of similar NZ roof jobs - clear product and prep details - confirmation of who is doing the work - a plan for safety and access - agreement on GST, timing, and warranty terms
If the job includes anything beyond simple repainting, check whether you also need council advice or a licensed specialist trade. The best roof painter will be upfront about that.
Taking the time to verify credentials can save you from poor workmanship, unsafe access, and costly do-overs. In NZ’s weather, roof painting is one of those jobs where getting it right first time really matters.
