Questions to Ask a Roof Painter Before You Hire Them

Why these questions matter

A roof painting job can look simple from the street, but good results depend on proper preparation, the right products, and safe work at height. In New Zealand, weather exposure is tough on roofs, so cutting corners can mean peeling paint, leaks, or a finish that fails far earlier than expected.

Before you hire a roof painter, the goal is to find out three things: can they do the work properly, are they properly protected if something goes wrong, and is their quote clear enough for you to compare with others? A good tradie will expect these questions and answer them clearly.

1) What roof painting experience do you have?

Start with the basics: how long have they been painting roofs, and what types of roofs have they worked on? Roofs in New Zealand can be corrugated iron, concrete tile, decramastic tile, COLORSTEEL®-type long-run profiles, or other metal systems. Different materials need different prep, primers and coating systems.

Ask:

• How many roof painting jobs do you complete each year?
• Have you worked on my roof material before?
• Do you regularly paint roofs in my area and climate?
• Can you show before-and-after photos of similar jobs?

Why it matters: a painter who mainly does interior or general exterior work may not understand roof-specific preparation, rust treatment, or adhesion issues. You want someone who knows the difference between a quick cosmetic repaint and a durable roof coating system.

2) Do you inspect the roof before quoting?

A proper quote should be based on an inspection, not just a drive-by estimate or a photo. A roof painter should ideally look at the roof condition, access, pitch, signs of rust or cracking, and any nearby issues such as gutters, flashings or skylights.

Ask:

• Will you inspect the roof in person before pricing it?
• Do you check for rust, cracked tiles, loose fixings or moss/algae build-up?
• Will you note any repairs needed before painting starts?
• Do you include washing and surface preparation in your quote?

If they do not inspect the roof, their price may miss important prep work. That can lead to “extras” later, or a finish that is applied over a surface that should have been repaired first.

3) What preparation is included?

Preparation is often the difference between a roof that lasts and one that fails early. In NZ conditions, roof prep commonly includes washing off dirt and biological growth, removing loose paint, treating moss and lichen, rust treatment, minor fastener replacement, and masking or protecting nearby surfaces.

Ask:

• Will you water-blast or soft-wash the roof, and how do you protect the property during cleaning?
• Do you treat moss, mould, lichen and algae?
• Will you sand, scrape or wire-brush rusted areas?
• Do you replace rusty screws or broken tiles, or is that extra?
• How do you prepare previously painted surfaces?

A very low quote can be a sign that prep has been reduced to the bare minimum. That may save money upfront but often costs more later.

4) What products and coating system will you use?

A roof paint job is only as good as the coating system behind it. Ask the painter what brand and product type they use, and why it suits your roof material and location. A roof near the coast, for example, faces more salt exposure than a roof inland.

Ask:

• What primer, undercoat and topcoats will you use?
• Is the product designed specifically for roof surfaces?
• Is it suitable for my roof material and local conditions?
• How many coats are included?
• Will you provide the technical data sheet or product information?

You do not need to be a paint expert, but you should know whether they are using a system, not just “roof paint”. A reliable painter should be able to explain the colour, finish, expected durability and maintenance requirements in plain language.

5) Are you licensed or qualified for this work?

Roof painting itself is generally not a licensed trade in the same way as plumbing, gasfitting or electrical work. However, that does not mean credentials do not matter.

Ask:

• Do you hold any relevant trade qualifications or manufacturer training?
• Are you a member of a trade or industry body?
• Do you work according to manufacturer specifications?
• Can you provide evidence of training or certification if relevant?

Also ask whether any related work is needed. For example, if the job includes electrical items such as solar panels, mast-heads or roof-mounted equipment, a registered electrician may need to be involved for any electrical work. If the painter identifies significant roof damage, structural repairs or re-roofing may fall under building work that could require consent depending on the scope. For major repairs, check with your local council.

6) Are you insured?

This is one of the most important questions to ask. A roof painter works at height, uses equipment around your property, and may be handling water blasting or spraying. Insurance helps protect you if there is accidental damage or a workplace incident.

Ask for:

• Public liability insurance
• Contract works insurance, if they offer it
• Workers’ compensation cover details, if relevant

Also ask:

• Can I see a current certificate of insurance?
• What damage is covered?
• Are my roof, gutters, garden and nearby surfaces covered while work is underway?

Do not rely on verbal assurances. Ask to sight current documents. If a contractor is reluctant to show them, that is a red flag.

7) Who will actually do the work?

Sometimes the person who gives the quote is not the person on-site. That is not necessarily a problem, but you should know who will be managing the job and whether subcontractors are involved.

Ask:

• Will you do the work yourself, or will subcontractors be used?
• Who will supervise the team on-site?
• How many people will be on the job?
• Will the same crew handle prep, painting and clean-up?

This matters for quality control and communication. If a subcontractor is used, ask whether they are insured and experienced with roof painting too.

8) What does the quote include — and what is excluded?

A written quote should be clear enough that you can compare it with at least two others. In New Zealand, price differences are often caused by hidden assumptions: one quote includes full prep and two coats, another allows only for a basic wash and one finish coat.

Use this table to compare quotes:

Ask:

• Is the quote fixed price or an estimate?
• Does it include GST?
• Are minor repairs included or extra?
• Are access equipment, water blasting, masking and clean-up included?
• What would count as a variation?

If the quote is vague, ask them to rewrite it in more detail before you sign anything.

9) How long will the job take, and when can you start?

Roof painting is weather-dependent. In many parts of New Zealand, late spring through autumn tends to offer more workable conditions, but even then rain, wind and dew can delay drying times. A professional painter should give you a realistic programme, not just a start date.

Ask:

• What is your expected start window?
• How many days will the job take in normal conditions?
• What happens if the weather turns bad?
• Do you work weekends or public holidays if the schedule slips?
• How long must the roof stay dry after painting?

Good timing matters because roof coatings need suitable temperatures and dry surfaces. If a contractor pressures you to paint in poor conditions, that is a warning sign.

10) What happens if you find damage during the job?

Older NZ roofs often reveal hidden issues once the cleaning starts. The painter may find rust perforation, cracked tiles, loose flashings, or failed sealants around penetrations.

Ask:

• How will you tell me if you find damage?
• Do you pause and price variations before proceeding?
• Can you handle minor repairs, or will you recommend another tradie?
• Will you photograph issues so I can see them?

You want a painter who is honest about what the roof needs, not one who simply paints over a problem. If the job starts moving beyond painting into repairs, you may also need to consider whether any building consent or specialist contractor input is required.

11) Do you provide a guarantee or workmanship warranty?

A guarantee can be helpful, but it is only useful if it is written down and realistic. Ask what exactly is covered: peeling, flaking, workmanship defects, or product failure? Also check the time period and any conditions.

Ask:

• How long is your workmanship warranty?
• What is covered and what is excluded?
• Does the product manufacturer provide a separate warranty?
• What maintenance is required to keep the warranty valid?
• What voids the warranty?

Be cautious of promises that sound too broad, such as “lifetime guarantee” without clear terms. A proper warranty should explain the limits, especially if roof maintenance is neglected or the roof is damaged later by storms or other trades.

12) Can you provide recent references?

References matter because roof painting is visible work, and past clients can tell you whether the company was punctual, tidy and communicative.

Ask:

• Can you give me two or three recent references?
• Have you completed similar jobs in the last 6–12 months?
• Can I view a nearby completed project, if appropriate?

When speaking to references, ask:

• Was the quote accurate?
• Was the site left tidy?
• Did they finish on time?
• Would you hire them again?

Online reviews can help, but recent direct references are usually more useful. You are looking for a pattern of reliability, not perfection.

13) How do you handle safety and site protection?

Roof work can be dangerous, especially on steep pitches or slippery surfaces. Good roof painters should have a safe system of work and protect your property while they are on-site.

Ask:

• What safety gear and fall protection do you use?
• How do you protect gutters, gardens, solar panels and vehicles?
• What happens to overspray or wash water?
• Do you follow safe access procedures for the roof?

If they cannot explain their safety approach clearly, think twice. Safety is not an optional extra.

14) What should be in the final agreement?

Before work starts, make sure you have a written agreement or accepted quote that covers the essentials. At minimum, it should include:

• Full scope of work
• Prep and repair allowances
• Product names and number of coats
• Total price and GST status
• Start window and expected duration
• Payment terms and deposit amount
• Warranty or guarantee details
• Variation process

A reasonable deposit is normal, but be wary of large upfront payments without a clear contract and references. Keep copies of all emails, quotes and invoices.

A simple checklist to use when you call around

When comparing roof painters, ask each one the same core questions so you can make a fair comparison:

• Have you painted my roof type before?
• Will you inspect the roof in person?
• What prep work is included?
• What products and number of coats will you use?
• Are you insured, and can you show proof?
• Who will do the work?
• What is excluded from the quote?
• How long will the job take?
• What warranty do you offer?
• Can you provide recent references?

Final advice

The best roof painter is usually not the cheapest quote, but the one who explains their process clearly, uses the right products, and backs up their work with proper insurance and references. In New Zealand’s harsh sun, rain and coastal conditions, a roof repaint is an investment in both appearance and protection.

Take your time, get multiple written quotes, and do not be afraid to ask follow-up questions. A good contractor will respect that.
