Many roof painters in New Zealand do offer minor repair work as part of a roof painting package — but how much they can legally and safely do depends on the type of damage, the materials involved, and whether a building consent is required. Understanding the boundaries helps you get the right tradesperson for the job and avoid costly surprises down the track.
What Repairs Can a Roof Painter Typically Do?
A skilled roof painter will usually inspect your roof before quoting and flag any issues that need attention before painting begins. It makes sense — painting over damaged or unstable surfaces leads to poor results and wasted money. Many roof painters are comfortable carrying out minor repairs as part of their service, including:
- Re-bedding and re-pointing ridge and hip tiles — replacing the mortar (bed) and flexible pointing compound that holds ridge capping in place
- Replacing a small number of cracked or broken concrete or terracotta tiles
- Resealing around penetrations such as skylights, vents, and pipes using appropriate roofing sealants
- Repairing or replacing small sections of flashing — particularly lead, aluminium, or butyl flashing around chimneys, valleys, and edges
- Clearing and resealing gutters and downpipe junctions where they meet the roof
- Applying roof membrane or waterproofing coatings to flat or low-pitch sections
These tasks are generally considered general building maintenance and don't require a licensed building practitioner (LBP) to carry them out, provided they are minor in scale and don't affect the structural integrity of the building.
When Does Repair Work Require an LBP or Building Consent?
This is where things get important. Under the NZ Building Code and the Building Act 2004, certain work is classified as restricted building work (RBW) and must be carried out or supervised by a Licensed Building Practitioner. This includes work that affects the weathertightness or structural integrity of a building.
If your roof has significant damage — for example, widespread tile failure, major flashing replacement across a large area, structural rafter or batten damage, or issues that could compromise the building envelope — this moves beyond what a roof painter should be doing. In these cases, you'll need a licensed roofer or builder.
Building consent may also be required for more substantial roofing work. Schedule 1 of the Building Act lists exemptions for minor maintenance and repair, but the line between exempt maintenance and consent-required work isn't always obvious. Always check with your local council if you're unsure.
MBIE Building Performance has clear guidance on what work requires consent and what qualifies as exempt repair and maintenance.
Flashing Repairs — What to Know
Flashing is one of the most critical weathertightness elements on any NZ roof. Poorly installed or repaired flashing is a leading cause of leaks and moisture damage — a serious issue given New Zealand's variable and often wet climate.
A roof painter can reasonably reseal or patch small sections of existing flashing using products like Sika roofing sealants or compatible flashing tapes. However, if flashing needs to be removed and replaced over a significant area, or if it's connected to a chimney, parapet wall, or complex junction, this is work best left to a qualified roofer or builder with LBP credentials.
Always ask your roof painter to be specific about what flashing work they're proposing and what products they'll use. Good-quality flashing repairs should be compatible with the paint system being applied.
Tile Repairs — Concrete vs. Terracotta vs. Metal
The type of roofing material matters:
| Roof Type | Minor Repair Suitability | Notes |
|---|---|---|
| Concrete tiles | Generally yes | Re-bedding, pointing, replacing individual tiles |
| Terracotta tiles | Sometimes | Older tiles can be fragile; sourcing matching replacements can be tricky |
| Metal (Colorsteel, Zincalume) | Limited | Sealing minor holes okay; panel replacement needs a roofer |
| Asphalt shingles | Limited | Uncommon in NZ; specialist knowledge needed |
| Membrane/flat roofs | Sometimes | Patching possible; full re-membrane is specialist work |
For metal roofing, BRANZ provides technical guidance on acceptable repair and coating methods that comply with NZ standards.
Questions to Ask Your Roof Painter Before the Job
Before signing anything, ask your roof painter:
- Are you an LBP? If so, in what licence class?
- What specific repairs are included in the quote, and what's excluded?
- What products will you use for repairs, and are they compatible with the paint system?
- Will the repairs carry any warranty, and for how long?
- Do any of the repairs require a building consent?
A reputable roof painter will be upfront about the limits of their scope and refer you to a licensed roofer or builder if the damage is beyond routine maintenance.
When to Call a Professional
Call a licensed roofer or LBP builder (rather than relying solely on a roof painter) if you have:
- Widespread tile cracking, slippage, or failure across large sections
- Suspected structural damage to rafters, battens, or sarking
- Major flashing replacement required (especially around chimneys or parapets)
- Evidence of significant water ingress or internal moisture damage
- A roof over 10 years old that hasn't been professionally inspected
You can find qualified roof painters and licensed roofers in your area through tradedirectory.co.nz. Always ask for references, check their LBP status if relevant, and get at least two or three quotes.
