Sydney, NSW
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
Sydney Roofing Company Pty Ltd is one of the more trustworthy outfits we've come across among the Sydney roofers we've reviewed, and the reasons are concrete. Its ABN is verified and active on the public register, the company name and address line up exactly, and its Google rating is a clean 5.0 across 11 reviews stretching from 2018 to 2026. Normally a perfect score on a thin listing makes us wary — but here the reviews are detailed, technical and spread over eight years, which is the opposite pattern. It reads like a small firm that has quietly kept every customer happy, not one gaming a fresh profile.
And the work described in those reviews is the real deal: a full terracotta-to-Monier tile re-roof with new membrane and battens; storm-repair work involving lead chimney flashings, ridge repointing and a fabricated chimney cap; and full roof replacements praised for upfront, thorough communication. Reviewers keep singling out the principal, Gavin (full name Gavin Brannigan in one review), and one calls him 'one of the few experts in Slate Roofs' — a genuinely specialised skill. We also noticed trade clients in the mix, including a building-company director ('Make Projects') and a bricklaying firm — which counts for a lot, because other trades stake their own reputation on who they sub-contract.
The honest limitations are about scale and sourcing, not quality. Eleven reviews is a modest sample, and we couldn't find an independent second rating platform beyond Google. Some of the backstory — a family roofing background in Ireland and moving to Sydney in 2009, which explains the slate expertise — comes from the firm's own account rather than an independent record, so treat it as a self-claim (though the slate specialism, at least, is backed up by a customer review). If you're after a verified, specialist slate/tile roofer on the east side of Sydney, we'd call this a low-risk pick — just confirm the licence and insurance paperwork as you would with anyone.

Who you'll actually deal with
Gavin Brannigan — the named owner-operator
This is unambiguously Gavin's business. He is named in almost every review — customers describe calling Gavin, Gavin explaining every detail of a re-roof, Gavin responding immediately to storm damage, and Gavin personally quoting jobs — and one review gives his full name, Gavin Brannigan. That level of consistent personal naming across eight years is a strong accountability signal: you know exactly who is responsible for the work and who you'll be dealing with.
According to the firm's own account, Gavin learned the trade from his father's long-running roofing business in Ireland, trained across slate, copper and tile, and moved to Sydney in 2009 — which is a self-claim we can't independently verify, but it squares with the slate expertise a customer independently praises. Practically, this is a small, principal-led team ('Gavin and his team' in the reviews), so you get direct access to an experienced tradesman, with the usual caveat that a small operation may have tighter capacity than a large re-roofing outfit at peak times.
What clients say
In their own words
I found Gavin to be a professional - communicating clearly and on time. He is one of the few experts in Slate Roofs
Gavin's work for our company has always been at a very high standard, we rely on Sydney Roofing for all elements of roofing on all of our projects from Slate to metal to tile. There high standard of finish and reliability is why we continue to use them. Tom Hume. Director. Make Projects.
Gavin and his team replaced our roof. They did an outstanding job - very efficient and professional. Communication with Gavin was excellent, he was upfront and thorough and his team were friendly and hardworking. We felt really well looked-after. Highly recommended!
Reviewers consistently praise Gavin's rare slate expertise, clear upfront communication, fair pricing and high-standard finish across repairs and full re-roofs, with repeat trade clients reinforcing his reliability.
Best for
- Slate, copper or heritage tile roofs — Gavin is described by a customer as 'one of the few experts in Slate Roofs', a genuinely specialised skill
- Full re-roofs and replacements (terracotta-to-Monier tile jobs, whole-house re-roofing) where reviewers highlight careful, well-communicated work
- Homeowners in Sydney's Eastern Suburbs / inner-south who want a verified, principal-led firm with a long, unbroken track record
Less suited for
- Buyers who want a large review sample or a second independent rating platform — this is 11 Google reviews and no ProductReview presence
- Anyone needing guaranteed rapid availability at scale — this is a small, owner-led team, so complex jobs may need scheduling
- People who need the firm's family/Ireland backstory independently documented rather than taken as a self-claim (the slate skill itself is corroborated by a review)
Before you commit
Five questions worth asking
- For a slate/copper job specifically, how many similar roofs have you done recently, and can I see or visit an example?
- Can you confirm your NSW roofing/building licence number so I can check it against your verified ABN (97 624 284 206)?
- Do you carry current public liability and work-at-height insurance — can you email a certificate of currency?
- What warranty do you offer on workmanship and on materials, and will you put it in writing?
- Will you personally be on site for my job, and can you provide a couple of recent local references I can call?
Bottom line
A verified, principal-led firm with a rare slate specialism, an unbroken eight-year 5.0 record and repeat trade clients — genuinely one of the safer picks we've found for tile, slate or full re-roof work, provided you confirm licence and insurance.
