How to Choose a Roofing Contractor in Adelaide — 7 Red Flags and Green Lights

Green Light 1 — Current SA building work contractor’s licence

In South Australia, anyone carrying out building work for others — including roofing — needs a building work contractor’s licence from Consumer and Business Services (CBS), with conditions that set the type of work they can do. Search the licensee at cbs.sa.gov.au and confirm the licence number on the quote matches an active record covering roofing. No active record = walk away.

Green Light 2 — Public liability + workers comp

Public liability insurance covers damage to your property. Workers compensation covers injury to the roofer’s crew on your site. Ask for current certificates. Without proper cover, an injury on your property can become a serious and expensive problem.

Green Light 3 — Installs to the manufacturer’s specifications

Manufacturer warranties (BlueScope for COLORBOND® steel, or the tile manufacturer) generally depend on the product being installed and maintained to the manufacturer’s guidelines. Ask the roofer to confirm the install will follow those guidelines and how the warranty is registered in your name.

Green Light 4 — Written, itemised quote

Material grade specified (e.g. ‘Colorbond Trimdek 0.42mm in Surfmist’). Labour line-itemed separately. Asbestos provision (what happens if found). Variation clause (how unforeseen conditions are charged). Workmanship warranty term. Quoted in writing on the company’s letterhead with ABN, licence, and contact details. Verbal-only quotes are a red flag.

Green Light 5 — Local references in your suburb

Not just generic Google reviews — actual customer references in Adelaide suburbs the operator regularly works in. The roofer should be able to drive you past 2-3 recent jobs and (with the customer’s permission) put you on a phone call with a previous client.

Red Flag 1 — Deposit above the legal limit

For domestic building work contracts in South Australia (contract price $12,000 or more), the deposit is capped: no more than $1,000 where the contract price is under $20,000, and no more than 5% where it is $20,000 or more. Further payments should be progress payments for work actually completed. A demand for a large upfront payment is a red flag — check the current rules with CBS.

Red Flag 2 — Door-knock quoting

Storm-chasing ‘door-knockers’ are a known pattern after Adelaide storms — they target damaged-looking roofs with high-pressure pitches and same-day decisions. Legitimate roofers do not knock doors and demand same-day signature. Always tell a door-knocker no, take a card if curious, and verify their licence and references later.

Red Flag 3 — Cash-only or no GST

Cash-only or no-GST ‘discounts’ mean no warranty paper trail. The ‘saving’ evaporates the moment you have a problem and the operator has changed phone numbers. Always pay through normal banking with a tax invoice.

Red Flag 4 — ‘Today only’ pricing

Quotes are normally valid for a set period stated on the quote. ‘Sign today and I can drop the price by $4,000–$6,000’ is a pressure tactic. Take 24–72 hours for any quote in the $5,000-and-above bracket.

Red Flag 5 — No physical address / interstate plates

An Adelaide roofer with a real local business address, an SA-registered ABN, and SA-registered vehicle plates is investing in being here long-term. Interstate fly-ins after storm events disappear when you have a warranty claim 5 years later.

Red Flag 6 — Unwilling to climb the roof

Drone-only quoting is fine for marketing photos but inadequate for accurate scoping on jobs in the $5,000-and-above bracket. The roofer should physically climb your roof, photograph close-up, and note any hidden costs (asbestos, structural issues). Quotes generated from satellite imagery alone can be well off the eventual job cost.

Red Flag 7 — No written warranty terms

‘Lifetime warranty’ verbally is meaningless. The warranty must be written into the contract: term length, what’s covered, what’s excluded, how to make a claim, who provides remedy. Bluescope’s manufacturer warranty is registered separately by name; ask to see the registration confirmation after install.
