AustralianRoofers Trust Score New
How it's calculated: a transparent, evidence-weighted score — identity & longevity from the public ABN register, reputation from verified Google reviews, and consistency from cross-checking independent platforms. Grades are proportional to the evidence. Where we search the register and can't confirm a business, the identity check scores zero rather than being quietly left out — so a firm we couldn't verify never outranks one we could. Longevity stays unscored in that case, because without a registration date there's nothing to measure.
Our honest take
Ascent Roofing is one of the cleaner files among the Wollongong roofers we've reviewed: a perfect 5.0 from 36 Google reviews, a registered private company (since September 2018, GST-registered a week later) whose ABR postcode matches its Unanderra address exactly, and an owner — Kane Cottell — whose name appears in review after review. When 22 mentions across 20 written reviews all name the same bloke, you're dealing with a genuine owner-operator, not a call centre.
The pattern in the reviews is unusually consistent: full re-roofs and tile-to-Colorbond conversions, done tidily, with customers repeatedly using words like 'quality' (11 mentions), 'professional' (7) and 'reliable' (4). Several reviews describe the whole arc from quote to clean-up — one Warilla customer with an old asbestos roof notes Kane organised the asbestos removal through a separate specialist company, which is exactly how that should be handled. The firm's own about page says Kane grew up working alongside his grandfather and uncles, all roof plumbers, and founded the business in 2017 — that's their telling, but the review evidence of hands-on expertise backs the general picture.
The honest caveats: a perfect 5.0 means we've never seen how this firm handles an unhappy customer — nobody's tested them in public. There's no ProductReview listing to cross-check the Google score against. And the site's own testimonials include a customer in Padstow (Sydney), so if you're calling from the Illawarra it's worth confirming your job fits their current run. None of these are red flags; they're just the limits of what 36 five-star reviews can prove.

Who you'll actually deal with
Kane Cottell — owner and director
Kane Cottell owns and runs Ascent Roofing, and unusually for a small trade business, you don't have to take the website's word for it — 22 of the review mentions name Kane directly, from quoting through to final clean-up, and one customer flat-out calls him 'Kane Manager Owner of Ascent Roofing'. The firm's about page says he's been in roof plumbing and carpentry since his early teens, learning alongside his grandfather and uncles, and founded the company in 2017 — that's their own story, but it fits the depth of expertise reviewers describe.
He's not entirely solo: reviewers also mention Meg (four times, mostly around booking and communication — 'Kane and Meg are really easy to interact with') and a Kurt on the tools in one review. We couldn't confirm their exact roles, so read those as the small team around an owner who's clearly on every job himself.
What clients say
In their own words
Kane and his team were great to deal with and they did a fantastic job. The guys were professional and reliable. They did our complete re-roof with ease and left the place looking spotless at completion. Would highly recommended using Ascent Roofing to anyone.
Its nice doing business with a straight shooter who has more of a focus on doing a quality job rather than talk. Kane takes pride in his work which ends up with a great outcome for customers
Ascent provided excellent service and pricing for a roof I ordered in Port Kembla to replace the old Terracotta roof. Great personal service from start to finish, excellent quality and kept informed through the whole process. I highly recommend Ascent if you are looking for a new roof.
Recurring themes are quality full re-roofs and tile-to-Colorbond conversions, fair pricing, being kept informed throughout, and a spotless site at completion.
Best for
- Full roof replacements and tile-to-Colorbond conversions — that's what most reviewers hired them for and raved about
- Homeowners who want the owner on the job and one point of contact from quote to clean-up
- Metal and Colorbond work — it's the firm's stated specialty and the reviews back it up
Less suited for
- Small one-off patch repairs — only a couple of the 36 reviews are repair jobs, so replacements are clearly the core business
- Anyone who needs a second independent review source before committing — there's no ProductReview file to cross-check the perfect Google score
- Jobs well outside the Illawarra — they've done Sydney work per their own testimonials, but confirm your area before assuming
Before you commit
Five questions worth asking
- Is my job the kind you prefer — a full re-roof or conversion — or is it too small to be worth your run?
- What's your roof plumbing licence number, and who holds it — Kane personally or the company?
- What warranty do you offer on workmanship, separate from the Colorbond material warranty, and is it in writing?
- If my old roof turns out to have asbestos, how do you handle removal — the same separate specialist a past customer mentioned?
- Who will actually be on site day to day — Kane, or a crew working under him?
Bottom line
A genuinely owner-run Wollongong re-roofing specialist with a clean company record and 36 straight five-star reviews that consistently name the owner. The only real gap is that no public review has ever tested them under complaint — everything we can verify checks out.
