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
GS Roofing sits at 4.7 across 40 Google reviews, and the happy majority tell a remarkably consistent story: this is a well-priced roof-restoration and repainting operator whose customers keep saying the quote was the cheapest of several, the work was clean and thorough, and small extras were thrown in at no charge. The praise words that come up most are 'professional', 'price', 'clean' and 'reliable' — so think value and tidiness rather than premium. We also liked that several reviewers walk through the full restoration process (pressure clean, repoint, primer plus two coats) done exactly as quoted, with before-and-after photos — that's the kind of concrete detail worth trusting for this sort of job.
The work leans heavily toward roof restoration, cleaning and painting, tile repairs, ridge-capping and repointing, with some leak and guttering work on the side. If what you're after is a cosmetic-and-protective refresh of an ageing tile roof at a sharp price, that's squarely their wheelhouse — and the reviews back it up strongly.
That said, we can't gloss over the negatives, because they're not trivial. Among the 40 reviews are three 1-star accounts: a leak repair that reportedly didn't hold with poor follow-up, a wrong-colour tile installed with a refusal to provide an invoice, and a blunt 'very unprofessional, avoid'. The owner disputes two of these publicly (suggesting one is a mis-directed or fake review), and one exchange reveals the workmanship warranty is only six months — short by industry norms. Whoever's right in each case, the pattern tells you where to be careful: get after-sales commitments, invoicing and the warranty length nailed down in writing before you engage.
Reputation across the web New
The same firm, checked across platforms
⚑ A cluster of serious negative reviews around after-sales, invoicing and warranty
Alongside many happy customers, GS Roofing has three 1-star reviews worth reading before you commit: (1) a leak repair a customer says never dried out, with follow-up that didn't materialise — the owner's reply notes the workmanship warranty is only six months; (2) a customer alleging a bright-red tile was installed on a charcoal roof and that an invoice was then refused; and (3) a short 'very unprofessional, avoid'. The owner publicly disputes at least two of these (implying one may be misattributed or fake). We can't adjudicate who's right, but the recurring themes — after-sales responsiveness, invoicing, and a short warranty — are exactly the things to pin down in writing up front. The owner's replies also tend to dispute rather than resolve, so get commitments documented.

Who you'll actually deal with
Gagandeep Singh ('Gagan') — solo owner-operator
This is an owner-operator business built around one person: Gagandeep Singh, whom nearly every reviewer calls 'Gagan' (and some 'Gagan paaji'). He's named in the clear majority of reviews as the person who quotes, does the work, and follows up — reviewers credit him personally for fair pricing, tidy work and throwing in small extras. Because he's the whole show, you'll deal with him directly from quote to completion, which is a plus for accountability.
The flip side is single-operator risk: capacity is limited to what one person (sometimes with an assistant) can do, and — as the negative reviews show — if a job goes wrong, resolution depends entirely on that one person's willingness and availability to come back. There's no larger office or team to escalate to, and the firm has a thin web presence (no substantial 'about' page was available), so what you see in the reviews is most of what's publicly knowable. Weigh that against the strong value the happy majority describe.
What clients say
In their own words
Gagan did a great job, his work ethic was amazing. Fixed extra bits at no charge, and painted some extra tiles as well. Super professional, and the quality of his work was outstanding. Glen, Justin Place, Quakers Hill
I have taken service from Gagan for multiple instances. He always on-time, professional and excellent at the work he delivers. Thank you so much and highly recommend him. Attaching a few photos of his recent roof paint work.
Amazing quality of roof restoration and roof painting work. More important at a very reasonable price compared to market price. Thanks for all the help with roof work,
The happy majority consistently praise sharp pricing, tidy full-restoration work done as quoted, and small extras at no charge, with owner-operator Gagan named throughout — set against a minority of serious after-sales and invoicing complaints.
Best for
- Homeowners in Western Sydney wanting a cost-effective tile-roof restoration, clean and repaint from a hands-on owner-operator
- Cosmetic-and-protective refreshes (pressure clean, repoint, primer plus two coats) where price and tidiness matter most
- People comfortable dealing directly with a single tradesperson and willing to document scope, price and warranty up front
Less suited for
- Anyone who wants a robust, longer workmanship warranty and a formal invoicing/paper trail — the warranty is reportedly six months and invoicing has been a complaint
- Complex or recurring leak jobs and full metal re-roofs, which are outside the review-evidenced sweet spot
- Homeowners who want the reassurance of a larger team to escalate to if after-sales issues arise — this is a solo operation
Before you commit
Five questions worth asking
- Exactly how long is your workmanship warranty, what does it cover, and will you provide it in writing with the quote?
- Will you provide a proper tax invoice with your ABN on completion, and can you confirm that before I book?
- Can you give me your NSW roofing/contractor licence number and confirm current public liability insurance?
- For my restoration, can you itemise the process (clean, repoint, primer, number of top coats) and the paint product so I can compare quotes like-for-like?
- If something isn't right after the job, what's your process and timeframe for coming back to fix it?
Bottom line
For a straightforward tile-roof restoration and repaint, this is strong value from a well-reviewed solo operator — but given the handful of serious complaints about after-sales follow-up, invoicing and the short six-month warranty, we'd get the scope, warranty and an invoice commitment in writing before you engage.
