What star rating should I expect from a good roofer in Unley?
The median Google rating across the 5 roofers Starworks ranks in Unley, SA is 4.7 stars, and 4 of them sit at 4.5 or above. A rating at or near that median is ordinary for roofers in Unley, SA rather than a warning sign on its own, and a rating well above it only means much when enough reviews stand behind it.
How many Google reviews does an established roofer in Unley have?
The median roofer Starworks ranks in Unley, SA carries 15 Google reviews.
How does Starworks rank roofers in Unley?
Starworks gives every roofer in Unley, SA a reputation score out of 100 from three things: its Google star rating (up to 47 points), how many reviews back that rating (up to 35), and whether customers can reach it by website and phone number (up to 18). Review volume is the one part that can subtract: below 15 reviews it costs points, because a near-empty review record gives a stranger very little to go on. No score falls below 0 and placement cannot be bought. The score measures the strength of a business's public review record rather than the quality of its work, so it is worth reading the reviews as well, and every listing links to them on Google.
Why does a roofer in Unley with all 5-star reviews score lower than one with a lower rating?
Because review volume counts as well as rating, and below 15 reviews it counts against you. Five perfect reviews are encouraging but thin evidence; three hundred reviews averaging 4.7 tell a stranger far more about what to expect on the day. That is a judgement about how much proof exists, not about the quality of the work, and a newer roofer with a handful of excellent reviews may still be the right choice in Unley, SA. The star rating and review count sit next to every score so you can weigh both yourself.
Why does the same roofer not appear several times on this list?
Some businesses run more than one Google listing, often one per suburb they service. Those are the same company, so Starworks groups them and shows the business once, using the listing with the strongest review record. That is why this page opens with 5 distinct roofers in Unley, SA rather than a longer list of repeats.
How often is this list of roofers in Unley updated?
This ranking of roofers in Unley, SA rebuilds on a 30-day cycle and prints the date of its last rebuild above the list, which for the current version is October 2026. Ratings and review counts are re-read from Google over time rather than on a fixed schedule, so an individual figure here can be older than the rebuild date.
How can I improve my roofer business ranking in Unley?
Collect genuine customer reviews consistently, and keep a working website and phone number on your Google listing, because those are the three inputs the score reads. There is no placement to buy on this page. For scale: the median roofer Starworks ranks in Unley, SA carries 15 Google reviews at 4.7 stars.
