Trading name of RM ROOFING SERVICES NSW · 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
RM Roofing Service earns a 4.6 from 31 reviews, and something we don't see often among the Sydney roofers we've reviewed: the review body is close to unanimous. Every review with written text is five stars, and the recurring subject is one man — Ryan McGuinness — and his small crew. Reviewers describe him as personable, transparent and genuinely skilled, with a clear specialty in converting old tile roofs to Colorbond metal on North West Sydney and Upper North Shore homes. Several accounts walk through full re-roofs handled cleanly on tricky, difficult-access sites — real evidence of capability, not just generic praise.
The firm holds up when you check the public record, too. Its ABN (21 204 908 837) is active and traces to the McGuinness partnership trading as RM Roofing Services NSW at Kenthurst — the firm's own suburb — which is about as clean a verification as a small operator gets. On their own site they mention two generations of roofing knowledge and a Contractor Licence #282365C; we're noting both as their claims rather than facts we've confirmed. One review even describes Ryan coming back to fix an unrelated fault at no charge — the kind of after-sale integrity that's hard to fake across a dozen independent reviewers.
The honest caveats are about scale and independence, not quality. This is a small, owner-led team — Ryan plus roof techs including Jack, and per the site Rudi and Jayden — so capacity is finite, and a big re-roof will be booked around their schedule rather than turned around instantly. We also couldn't find a ProductReview listing or any other second rating, so the strong picture rests entirely on Google. And the coverage is concentrated in the Hills District and North Shore — if you're well outside that belt, check they'll travel to you before you get attached.

Who you'll actually deal with
Ryan McGuinness — proprietor and hands-on lead
Ryan McGuinness is unambiguously the person you deal with: he is named in the overwhelming majority of reviews and is listed as Proprietor on the firm's own site, which describes 'two generations of knowledge' in the trade. Reviewers single him out for clear, proactive communication — daily progress photos on bigger jobs, plain-language explanations of materials and costs, and a willingness to suggest better roofing detailing than what was there before. He personally responds to almost every Google review, which reinforces how owner-driven the business is.
The wider crew appears repeatedly and is a genuine team, not a solo act. Jack shows up in many reviews as Ryan's roof technician (one reviewer notes Jack works alongside his dad Graham), and the firm's site names roofing techs Rudi and Jayden. This is the strength and the constraint of an owner-operator model in one: you get consistent, personal accountability from the top, but the same small team handles everything, so scheduling a large re-roof means fitting into their queue.
What clients say
In their own words
Ryan and his mate did a great job replacing a few thousand corroded roofing screws etc. On time and no mess, would highly recommend.
We have our gutters and fascia replaced by RM Roofing Services. Ryan and Jack were very efficient and know what we want. They were honest and reliable and I think it's value for money. Thank you so much Ryan and Jack.
Highly recommend RM Roofing, completed new metal roof, very professional and quality of workmanship was amazing!!
Recurring themes are clean, tidy workmanship, strong proactive communication (often with progress photos), and tile-to-Colorbond re-roofs delivered on difficult sites — with Ryan named personally again and again.
Best for
- Homeowners on Sydney's North West and Upper North Shore wanting a full tile-to-Colorbond re-roof done cleanly
- Anyone who values daily photo updates and plain-English explanations of materials, costs and roofing detail
- Tricky, difficult-access sites where an experienced hands-on lead matters more than a big crew
Less suited for
- Large commercial or strata jobs needing significant crew scale — this is a small owner-led team
- Homeowners well outside the Hills District / North Shore who need to confirm the firm travels to them
- Anyone wanting a second independent rating to cross-check — there is no ProductReview listing
Before you commit
Five questions worth asking
- Will you personally lead my job, Ryan, or will one of the roof techs run it?
- Do you service my suburb, and does travel affect your quote?
- For a tile-to-Colorbond conversion, what insulation and detailing do you recommend and why?
- Can you send progress photos during the job as some of your reviewers describe?
- Can you confirm your Contractor Licence #282365C and current insurance in writing before work starts?
Bottom line
A small, owner-led team with an exceptionally consistent five-star review body and a cleanly verified ABN in the McGuinness family name — we'd call it a strong pick for a North Shore re-roof, as long as you're happy booking around a small crew and relying on Google as the sole rating source.
