MILLSTONE Roof repair + Carpentry
Trading name of Millstone Services · 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
Millstone is one of the strongest small-roofer profiles we've come across: a flat 5.0 across 30 Google reviews, and when we read them they were detailed, varied and specific rather than templated. Homeowners repeatedly describe Tom (Tamas) finding and fixing hard-to-trace leaks that other companies had quoted on and missed, replacing skylights, re-engineering a rusted shed roof, building a bespoke gutter, and doing the associated carpentry — rotten facia boards, a rotted-through balcony, decking. The praise goes beyond 'professional' to 'honest', 'knowledgeable', 'trustworthy' and 'attention to detail', and several reviewers specifically note he explains the most cost-effective option without upselling. That's a diagnostic, problem-solving roofer, not a patch-and-run operator.
It's also unusually easy to verify — which we appreciated. The Australian Business Register confirms the business is Tamas Monus trading as Millstone Services (ABN 37 988 268 561), a North Shore sole trader active since April 2013, which independently backs up the firm's own claim of 'serving the North Shore since 2013'. And the website's more distinctive claim — that founder 'Tom' has a Civil Engineering degree from Hungary and a background in structural engineering and building-defect remediation — is echoed in the reviews themselves, where clients volunteer that 'with an engineering background he understands far more than just roofing'. So the engineering angle isn't just marketing; customers notice it without prompting.
The honest limitations are all about scale, not quality. This is essentially a two-person operation — Tom does the work with a named offsider, Peter — so capacity is finite and it's quote-first rather than a 24/7 emergency crew (though several reviews mention next-day callouts). It's focused on the North Shore, so it's most relevant if you're in that catchment. And there's no independent second review source, so the strong picture rests on Google plus the firm's own site — softened here by the register lining up with both. If you're a North Shore homeowner with a tricky leak, a skylight, or a roof-plus-carpentry job that needs someone who'll actually diagnose the cause, we'd call this a genuinely low-risk, high-quality pick.

Who you'll actually deal with
Tamas 'Tom' Monus — owner-operator (with Peter)
The principal is named around 47 times across the reviews as 'Tom' or 'Tamas' — one reviewer helpfully writes 'Tamas (Tom)' to make clear they're the same person — and the Australian Business Register confirms his identity as Tamas Monus, holder of the 'Millstone Services' business name. The firm's own site describes founder Tom as holding a Civil Engineering degree from Hungary with a background in structural engineering, project management and building-defect remediation before specialising in roof and gutter work; unusually, that engineering background is independently echoed by reviewers ('with an engineering background, he understands far more than just roofing'). Clients consistently describe him as honest, communicative, willing to explain options in plain language and photograph the problem — the accountable owner-operator pattern, and here it's verifiable rather than just claimed.
He isn't strictly solo: a named offsider, 'Peter', appears in several reviews doing skylights, guttering and carpentry alongside Tamas, so treat this as a small two-person team led hands-on by the owner. That's a plus for consistency and accountability, but a reminder that capacity is finite — for a larger project, confirm the crew size, timeline and lead time up front.
What clients say
In their own words
Tom did a great job replacing a smashed skylight. Then proceeded to replace the flashing of the rest at no extra charge. Amazing service. Lovely guy.
We were very impressed with the work of Millstone. Tom spent time understanding what was required and explaining options to us. He and Peter were thorough and professional in their work and pleasant to deal with. We would not hesitate to engage them in the future and recommend them to others.
Tom is great. We felt very comfortable dealing with him throughout. He explained the most cost effective way to fix our roof. Tom is very knowledgeable and did a fantastic job fixing the fault with our roof. If you have any problem with your roof, Tom is the man.
Recurring themes are diagnosing and fixing hard-to-find leaks other roofers missed, honest cost-conscious advice with no upselling, meticulous attention to detail, versatility across roofing, skylights, gutters and carpentry, and a tidy, trustworthy owner-operator.
Best for
- North Shore homeowners with a stubborn or hard-to-trace leak that other roofers have failed to diagnose — the single most-praised competency in the reviews.
- Combined roof-and-carpentry jobs (skylights, rotten facia/balcony/decking, bespoke guttering) where the engineering-minded, versatile approach genuinely shows.
- People who value an honest, verifiable owner-operator who explains the most cost-effective fix in plain language and documents the problem with photos, rather than upselling.
Less suited for
- Large-scale or time-critical projects needing a big crew and formal capacity guarantees — this is essentially a two-person operation, quote-first.
- Homeowners outside the Sydney North Shore catchment, where the firm's focus and reviews are concentrated.
- Buyers who want a second independent consumer-review source before committing — the rating rests on Google (plus the firm's own site), with no ProductReview or comparable listing to cross-check.
Before you commit
Five questions worth asking
- Will the quote and invoice be issued under Millstone Services (Tamas Monus, ABN 37 988 268 561), and can I have the scope, options and price in writing before work starts?
- For my leak or roof fault, how will you investigate and confirm the actual cause before quoting a fix — will you provide photos of what you find?
- Will you (Tom) and Peter be doing the work personally, and what's the realistic crew size and timeline for a job of my size?
- For the carpentry / structural elements (facia, decking, waterproofing), what materials and method are you using, and what workmanship guarantee do you provide in writing?
- Are you covered by current public liability insurance, and can you confirm the appropriate licensing for the roofing and building work involved before you start?
Bottom line
This is one we'd recommend to a friend on the North Shore without hesitation: Tamas 'Tom' Monus is named across the reviews and confirmed on the register (ABN 37 988 268 561, trading since 2013), with detailed praise for diagnosing leaks others missed and honest, no-upsell advice. The only real caveats: it's a small two-person, quote-first team focused on the North Shore, and the rating rests on Google alone.
