The LBP Roofing class — the regulatory moat

Roofing is one of the LBP classes under the Building Act 2004. Restricted Building Work that affects weather-tightness — which covers most re-roofing, flashings, valleys, penetrations — must be carried out or supervised by a licensed roofer. That's the regulatory layer that protects your hourly rate from unlicensed competition. The licence requires evidence of work, a portfolio, and an LBP assessment — most experienced roofers qualify on first application.

Annual CPD points (~12/yr) keep the licence current. The Roofing Association of NZ (RANZ) and Master Roofers run accredited CPD workshops — usually one weekend a year covers it. Lapsed licence = invalid sign-offs = council Code of Compliance refused = customer's insurance won't cover any subsequent leak. Stay current.

Where the residential market actually is

Half of NZ houses are 30+ years old. The original longrun steel from the 1980s-90s is at end-of-life, the tile roofs from the 1960s-70s need replacement or major repair, the 2000s leaky-build era left thousands of houses with weather-tightness problems still being remediated. That's a 25-year backlog of work that small roofing operators can pick from.

Lead sources: (1) Google search for 're-roofing [city]' and 'roof repair [suburb]' — the highest-intent traffic; (2) real estate agents — every pre-sale building report flags roof issues; (3) insurance assessors — IAG, Tower, Vero handle thousands of storm-damage roof claims annually; (4) builders + LBPs subcontracting roofing as part of larger renovations. Build relationships with 5-10 builders in your patch and that alone fills a calendar.

Working at Heights — the safety regime that's also a sales tool

Roofing is one of the highest-injury trades in NZ (WorkSafe data, 2024-25 published). Edge protection, harness systems, certified anchors and proper scaffolding are mandatory under the Health and Safety at Work Act 2015. Customers (especially commercial / body corporate) ASK about your safety setup and your insurance — being able to walk through the system articulately wins quotes against operators who can't.

For older roofs (pre-2000), asbestos is a real consideration. Cement-fibre tiles from the 1960s-70s and some bitumen membranes contain asbestos. NZ asbestos awareness training (one-day course, $300–$500) is a legal requirement for any work that disturbs material that might contain asbestos. Worth doing in year 1 — opens up the older-roof market that less-careful operators avoid.

Insurance + storm work — the dependable winter income

Every NZ winter brings a major storm event. Auckland 2023, Hawke's Bay 2023, Wellington 2026 — every event drives 6 months of insurance-funded roof repair work at fair commercial rates. Get on the assessor list at IAG (the largest), Tower, Vero and Vero Liability — they actively need roofers for claims work. The paperwork is heavier than residential cash work but the cheques clear reliably.
