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
JSIU Roofing is essentially Joel — his name appears in the overwhelming majority of the firm's recent reviews, and the picture they paint is remarkably consistent: he turns up fast (one reviewer had him on site within an hour), diagnoses carefully, explains options at different price points, and then documents everything. Google's own review-mining backs this up in an unusual way — 'thoroughness' is the single most-tagged theme across his 242 reviews, with 'clear explanations' second. Reviewers describe follow-up emails with photos, before-and-after videos, even a recorded job safety assessment. Of the Melbourne repairs outfits we've reviewed, nobody documents their work like this.
The verification side holds up too. The ABN checks out — registered to the JSIU C & R Projects trust in Craigieburn, active and GST-registered since August 2019 — and the business is visibly real across platforms: an online store selling tile clips, valley clips and SolarKing roof vents, a YouTube channel of how-to videos, and 179 further reviews on ServiceSeeking. The firm's claims of BPC registration, full insurance and a 10-year workmanship guarantee are their own statements we haven't independently verified, but the overall pattern is a business that wants to be checkable — which is rarer than it should be in roofing.
Honest caveats: the record is repairs-and-inspections heavy, so if you're after a full re-roof, you're relying on their word (and their 10-year guarantee claim) more than on review evidence, and a one-man-band operation means capacity limits on big jobs. The rating isn't literally perfect either — 13 of the 242 reviews sit below five stars, which is a normal, believable distribution rather than a concern. And note the website says 'Pty Ltd' where the ABR says trust; ask which entity signs your contract.

Who you'll actually deal with
Joel — owner-operator, and the reason people call back
Joel is named 22 times across the firm's twenty most recent reviews — the highest single-person mention rate of the Melbourne roofers we've reviewed. Customers describe him diagnosing leaks during storms, arriving within the hour, offering options at different price points, and once fixing a botched restoration another contractor had abandoned. An interstate owner specifically praised being able to manage repairs remotely because of how Joel communicated. One review also thanks 'Joel and Sandra' — a second name we couldn't attach a role to, though it suggests there's admin support behind him.
His trade-platform profiles say he's been in building and construction for over a decade and started out in 2014 focusing on insulation and roof maintenance — the firm's own account, and consistent with the 'JSIU Insulation' name that still lingers on older listings. The registered paper trail starts a bit later: the trust's ABN dates from August 2019, and the JSIU ROOFING business name from December 2022. Either way, what you're buying here is one experienced, well-documented operator rather than a crew — with the responsiveness and the capacity limits that implies.
What clients say
In their own words
Fantastic customer service. Responded promptly to all of my queries and quickly helped me with installation of my tile clips with a concise explanation and video which was spot on. Highly recommend these guys!
Being interstate I was not sure I could find a reliable roof repairer in Victoria. Joel went out of his way to ensure the roof repairs I needed were completed on time and of a high standard. I found JSIU Roofing to be very professional, knowledgeable, honest and friendly. Thank you Joel and Sandra
Proper tradie which is impossible to find this days. Came on a short notice, professional in every sence of the word. Fixed the roofing and gutters issues we had and gave us professional advice. Also, fair with pricing and finding cheaper solutions for the issues. Most highly recommended!
Recurring themes: fast response, thorough inspections with photo and video documentation, honest options at multiple price points, and clear explanations that even interstate owners could act on remotely.
Best for
- Leak diagnosis and roof inspections where you want a documented report with photos — including pre-purchase checks and insurance claims
- Repairs, repointing and tile work in Melbourne's northern corridor (Craigieburn, Roxburgh Park, Epping, Wollert and surrounds)
- Roof ventilation and insulation work — SolarKing vent installs are a genuine specialty, with their own supply-and-install packages
Less suited for
- Full re-roofs and tile-to-Colorbond conversions — they advertise them, but the review record is almost entirely repairs and inspections, so you'd be relying on their claims rather than evidence
- Large or urgent multi-crew projects — this is fundamentally one skilled operator, and the responsiveness reviewers love comes with capacity limits
- Anyone who just wants the cheapest patch job with no paperwork — the thorough inspect-document-explain approach is the product here, and you're paying for it
Before you commit
Five questions worth asking
- Which entity will be on my contract and invoice — the JSIU C & R Projects trust (ABN 46 449 844 148) or the Pty Ltd your website mentions?
- Can I see the 10-year workmanship guarantee in writing — what exactly does it cover, and does it survive if the business structure changes?
- Will you do the work yourself, Joel, or is any of it subcontracted?
- Does the inspection price include the written report with photos, and can I use it for an insurance claim or pre-purchase decision?
- Your site routes projects over $7,000 to a separate email — for a job that size, what's the payment schedule and who else works on it?
Bottom line
One of the most verifiable small operators we've reviewed: a real ABN in the right suburb, 242 Google reviews corroborated by another 179 on ServiceSeeking, and a documentation habit most big firms can't match. For diagnosis, repairs and ventilation in the northern suburbs he's an easy recommendation — just confirm the contracting entity and get that 10-year guarantee on paper.
