NSW Slate Roofing - Sydney
Trading name of NSW SLATE ROOFING PTY LTD · 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
NSW Slate Roofing holds a 4.7 average from 42 Google reviews, and what struck us most is the kind of work it wins praise for: this is a genuine traditional-slate specialist, not a general re-roofer that also does slate. The firm's own site describes a director who trained as a slater in Wales on heritage-listed buildings, and the reviews back up the premium positioning — a remedial builder who trusts them across multiple projects over years, an electrical contractor citing a near-ten-year working relationship, and a homeowner calling them the best team to touch their slate roof in 30 years. If you've got heritage, Welsh/Spanish/Canadian slate or complex traditional work, that depth of specialism is the headline reason to call them.
The themes that keep recurring are professionalism, clear communication (detailed quotes, progress updates through multi-week jobs, follow-up calls after bad weather) and consistently clean, tidy worksites. Just as importantly, the reviews show they do responsive repairs too, not only large restorations: one homeowner had repairs turned around at short notice before heavy rain, and others describe leak and maintenance work. We also noticed the praise skews toward trades who use them repeatedly — builders and subcontractors as well as homeowners — which tells you the workmanship holds up to a professional eye.
The honest limitations are about fit and evidence rather than any red flag. This is a specialist heritage/slate company, so for a routine tile-roof patch or a budget re-roof they may be more firm — and more expensive — than you need; their strengths are aimed at slate, shingle and higher-spec jobs. The rating is a solid 4.7 rather than a flawless 5.0 (a small number of non-5-star reviews sit behind the average, though we couldn't see any detailed complaint in the recent set), and Google is the only independent review source we could confirm — no ProductReview or comparable second platform turned up, so you're relying on one source, albeit a detailed and consistent one.
Reputation across the web New
The same firm, checked across platforms
⚑ Reviews name both 'Craig' and 'Carl' — most likely the same person
Several reviews thank 'Carl' while others thank 'Craig', and the firm's Meet the Team page lists a General Manager named Craig Walker but no one called Carl. In context (same role, same praise, same period) 'Carl' reads as a common misspelling of 'Craig' rather than a second staff member. We've assumed they're the same person, but if you're checking who your point of contact will be, it's worth confirming the name directly — nothing here suggests a problem, just a spelling quirk in the reviews.

Who you'll actually deal with
Director Kinsley Denning and GM Craig Walker
On the firm's own Meet the Team page, NSW Slate Roofing is run by Director Kinsley Denning and General Manager Craig Walker, described as taking a hands-on approach with over 30 years' combined experience. The site says Kinsley trained as a slater in Wales from age 16, built a reputation on heritage-listed buildings there, and migrated to Australia before the company was incorporated — the classic 'master slater' backstory that underpins the firm's heritage positioning. Treat the specifics (years, heritage work) as the firm's own account, but it's consistent with the kind of work the reviews describe.
In the reviews, Craig is the name that comes up most often (with 'Carl' almost certainly the same person — see the flag above), typically as the person managing quotes, communication and job progress; Kinsley is named alongside him on larger jobs, and 'Sam' appears once too. So while there's clearly a crew doing the work, the client relationship on most jobs runs through Craig as the day-to-day contact, with Kinsley as the technical/heritage lead.
What clients say
In their own words
As a remedial builder, quality and reliability are critical to me. Carl and his team have delivered across multiple projects over the years, consistently on point. Professional, dependable, and easy to work with. Hats off to a good business — thank you Carl and the team.
Highly recommend the team from the NSW Slate Roofing. Excellent workmanship, reliable and efficient. I was so happy to get the repairs done within a short notice and before the heavy rain happened in May 2025. Thank you, Craig.
Great perseverance with an architectural shingle re-roof that had some surprises. Nice guys to deal with.
The recurring themes are trusted, repeat-business workmanship (praised by builders and subcontractors as well as homeowners), strong communication with detailed quotes and progress updates, and responsive repairs on slate and heritage roofs left clean and tidy.
Best for
- Heritage, traditional and natural-slate roofs (Welsh, Spanish, Canadian, composite) where genuine slate specialism matters more than lowest price
- Slate roof repairs, restorations and ongoing maintenance where clear communication and a tidy worksite are priorities
- Builders, remedial contractors and owners of higher-spec homes who want a specialist that other trades trust with repeat work
Less suited for
- Routine tile-roof patches or budget re-roofs, where a general roofing contractor may be a better and cheaper fit than a heritage-slate specialist
- Buyers who want a second independent review platform to cross-check, as no confirmed ProductReview or comparable listing was found beyond Google
- Anyone needing an instant emergency call-out — the reviews show responsive scheduling and repairs, but the firm's strengths are considered, quoted specialist work rather than 24/7 rapid response
Before you commit
Five questions worth asking
- As a slate specialist, is my job natural slate, composite or a different material — and which do you recommend and why for my roof?
- What is your current NSW roofing/building licence number, and does it cover the specific work (including any heritage requirements) on my property?
- Can you provide a certificate of currency for your public liability and workers' insurance before work starts?
- What written warranty do you offer on this work, and what does it cover (materials vs workmanship, and for how long)?
- Who will be my day-to-day point of contact and site manager (Craig, Kinsley, or someone else), and how will you keep me updated through the job?
Bottom line
A credible, properly incorporated heritage-slate specialist (NSW SLATE ROOFING PTY LTD, trading ~14 years) whose reviews consistently praise the workmanship, communication and tidy jobs — and the repeat business from other trades is one of the stronger trust signals we've seen. Best suited to slate and heritage work rather than budget tile jobs; confirm licensing, insurance and warranty directly, and keep in mind Google is the only independent review source we could verify.
