How this order is decided
One sort, on one figure: the share of a roofer’s Google ratings that are one or two stars, lowest first. Both numbers behind it — how many ratings are one or two stars, and how many there are in total — are printed beside every name, so you can check the order against the page and the page against Google.
Roofers whose share prints the same figure share a position number, because they are tied on the only thing being ordered. Within a tie the one with more ratings behind it is listed first; if that is equal too, the higher star average, and then alphabetically. Those last steps only ever separate roofers the figure itself cannot, and they exist so the order is the same every time the site is rebuilt rather than shuffling.
There is no Roof Warden score, no editorial pick and nothing anyone can pay for. We only rank roofers we list with at least 40 ratings, because below that a single unhappy customer swings the percentage by more than the differences we would be ordering on. That leaves 5 roofers on this page unranked — which says nothing about their work, only that there are too few ratings to sort on.
This is not every roofer in Oshawa. We list 19, captured from public Google listings, and rank the 14 with enough ratings to compare. Treat it as a shortlist to check, not a complete market.
