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
GTB Roof Restoration carries a perfect 5.0 across 64 Google reviews, and what pleased us most when we read through them is that they describe genuine, full-scope roofing work: complete restorations (clean, repoint, replace broken tiles, Dulux Acratex paint), new Colorbond metal roofing, asbestos-roof replacement, gutters, downpipes, fascia, valley and gutter guards. Plenty of firms we've looked at have evidence that's thin or drifts off-trade — this one is squarely a roofing specialist with a broad, demonstrated skill set, and the praise for communication, progress photos and tidy sites repeats consistently across a big pool of reviews.
You also know exactly who you're dealing with. 'Harry' (occasionally spelled 'Hary') is by far the most-mentioned name — he runs the inspections, quoting and communication — with 'Lakha' (also 'Laksha') repeatedly named as his hands-on work partner. Reviewers describe a small, accountable team that shows up, explains the scope clearly, sends photos and finishes on schedule 'no matter the weather'. That's a warm, human, owner-led operation — the opposite of a faceless outfit.
The honest caveats are about track record and sourcing, not workmanship. When we verified the company (GTB Roof & Restoration Pty Ltd, ABN 24 681 270 208, Blacktown), it checked out as real but very new — registered only in October 2024 — which means the website's '25+ years / 500+ clients / 1000+ projects' figures can't describe the company itself; treat them as unverified claims about the team's broader experience. We also couldn't find an independent second review source, so the 5.0 stands on Google alone. Our read: a capable full-scope roofer with an excellent but short official history.

Who you'll actually deal with
Harry and Lakha — a named, hands-on two-person core
There's no ambiguity about who you'll deal with. 'Harry' is the dominant name across the reviews — repeatedly credited with the initial inspection, the detailed quote, coordinating access (in one case directly with a tenant) and keeping customers updated with progress photos. 'Lakha' (spelled 'Laksha' in a couple of reviews) is named alongside him as the detail-oriented hands-on partner on jobs like gutter replacement, re-roofing and restoration. Multiple reviews name both together, which is the clearest possible signal of a small, accountable team rather than sub-contracted labour.
The firm's own About page keeps things brand-level ('our experienced team', 'years of industry experience') and names no individuals, so the reliable read on the people comes from the reviews — and they point squarely at Harry as your main contact and Lakha as his on-site partner. As with any small owner-led crew, the upside is direct accountability; the constraint is finite capacity, so scheduling may depend on their existing workload and the weather.
What clients say
In their own words
Recent got my sun room roof redone with GTB. Both Harry and lakha have done a great job. They installed colour bond roofing with metal flashing. Definitely recommend.
Harry and his guys are super responsive and did an amazing job. From start to finish, everything was super professional, the communication was great and the finish was better than expected.
Great job by the GTB team. I am so impressed with their professionalism and dedication to finish the job in a timely manner. Received all the photos after work and they fix everything properly. Highly recommend them.
Recurring themes: clear upfront quoting and communication from Harry, genuine full-scope roofing (restoration, re-roofing, guttering, painting), progress photos, tidy sites and jobs finished on time regardless of weather.
Best for
- Homeowners in Sydney's west wanting a full roof restoration or re-roof — tiles cleaned, repointed and painted, or a Colorbond metal replacement — from a named, hands-on team
- People who value clear scope explanations, regular progress photos and a tidy, respectful crew (several reviews specifically praise care around tenants and elderly residents)
- Anyone needing combined works in one go — restoration plus new gutters, downpipes, fascia, valley or gutter guards — rather than juggling separate trades
Less suited for
- Homeowners wanting a long, established corporate track record — the company was only registered in late 2024, so the perfect 5.0 sits on a short official history
- Buyers who want to weigh the website's headline stats ('25+ years', '1000+ projects') — these are unverified self-claims that don't match the entity's one-year age
- Anyone who specifically wants a second independent review source to cross-check before committing — only Google reviews exist for this firm
Before you commit
Five questions worth asking
- Your site says '25+ years experience' but the company was registered in 2024 — is that your personal/team trade experience, and how long has GTB itself been operating?
- Can you confirm your roofing licence number and provide a current public liability insurance certificate before work starts?
- For my job, exactly what's included in the scope — e.g. clean, repoint/re-bed ridge caps, replace broken tiles, paint coats and product (you've used Dulux Acratex) — in writing?
- Will Harry and Lakha do the work directly, or will any of it be sub-contracted, and who's my point of contact during the job?
- What workmanship warranty do you provide, in writing, and will I get before-and-after progress photos as several of your reviewers mention?
Bottom line
A genuinely full-scope, owner-led roofing specialist with a spotless 5.0 and consistent praise for communication and tidy work — we'd just remind you the company is only about a year old on paper, the website's big round-number stats are unverified, and it's worth getting the licence, insurance, scope and warranty in writing.
