Yes — many gutter cleaners in New Zealand will cast an eye over your roof while they're up there, and some offer a more structured visual inspection as part of their service. However, there's an important distinction between a general observation and a formal building inspection report, and knowing the difference can save you from costly surprises down the track.
What a Gutter Cleaner Typically Does on Your Roof
When a gutter cleaner visits your home, they're usually working at height along the roofline and guttering. While they're up there, it's natural — and genuinely useful — for them to notice obvious issues such as:
- Cracked, slipped, or missing roof tiles or corrugated iron sheets
- Damaged or blocked downpipes and spouting
- Visible moss, lichen, or debris build-up on the roof surface
- Obvious flashing problems around chimneys, skylights, or penetrations
- Sagging gutters or sections pulling away from the fascia
- Signs of rust on metal roofing or gutters
A good gutter cleaner will flag these observations to you verbally or in a basic written note. This kind of heads-up is valuable and can prompt you to act before a small problem becomes a major leak.
What They Cannot Formally Report On
Here's where it gets important. A formal building inspection report — the kind used for property purchases, insurance claims, or building consent purposes — must be carried out by someone with the appropriate qualifications and, in many cases, by a Licensed Building Practitioner (LBP).
Under New Zealand's Licensed Building Practitioners scheme, certain building work and assessments are restricted to those holding the relevant licence class. While a general visual roof observation isn't necessarily restricted work, a written report that makes structural or weathertightness assessments — especially one relied upon for legal or financial decisions — should come from a qualified inspector or LBP.
Gutter cleaners are typically not LBPs, and most are not trained building surveyors. Their observations are useful, but they shouldn't be treated as a substitute for a professional building inspection.
The Weathertightness Factor
New Zealand's climate — particularly in wetter regions like Auckland, the West Coast, and Wellington — means roofs take a real hammering. The NZ Building Code sets out requirements under Clause E2 (External Moisture) to ensure roofs and claddings keep water out. Identifying weathertightness failures properly requires trained eyes and sometimes specialist equipment.
If your gutter cleaner notices something concerning — say, lifted flashing or cracked ridge capping — treat it as a prompt to get a proper assessment, not as a definitive diagnosis. BRANZ is New Zealand's leading building research organisation and has excellent guidance on roof maintenance and weathertightness that's worth reading.
What to Look for in a Gutter Cleaner Who Offers Roof Checks
If you want a gutter cleaner who can give you a more thorough roof overview, look for someone who:
- Has experience with your roof type (tile, corrugated iron, long-run steel, membrane flat roofs)
- Takes photos of any issues they spot and shares them with you
- Provides a written summary of observations (not a formal report, but useful notes)
- Is insured — public liability insurance is important when someone is working at height on your property
- Is honest about the limits of their expertise and will recommend a specialist when needed

When You Need a Formal Roof or Building Inspection
There are situations where a gutter cleaner's observations simply aren't enough and you should engage a qualified building inspector or LBP:
- Buying or selling a property — a pre-purchase inspection by a qualified inspector is strongly recommended
- After a significant weather event — storm, hail, or earthquake damage may require an insurance-grade assessment
- Suspected weathertightness issues — water staining on ceilings, mould, or damp walls need proper investigation
- Before major roof repairs or replacement — understanding the full scope of work requires expert assessment
- For consent-related work — any roofing work that may require a building consent should involve an LBP; always check with your local council about consent requirements
MBIE Building Performance has clear guidance on when building consents are required and what falls under Schedule 1 exemptions — but confirm specifics with your council, as requirements can vary.
A Note on Safety
Roof and gutter work involves working at height, which is a leading cause of serious injury in New Zealand. WorkSafe NZ has strict guidelines around working at height. Always hire someone who follows safe working practices — proper ladders, harnesses where required, and appropriate footwear for roof surfaces. Don't attempt to inspect your own roof unless you have the right equipment and training.
When to Call a Professional
Call a qualified building inspector or LBP if you need a formal written report, are buying or selling a home, have signs of leaks or structural concern, or need documentation for insurance. Call a licensed roofer for any repairs beyond minor maintenance. Your gutter cleaner is a great first line of observation — but know when to escalate.
