How to read this list
The default order is by how many ratings Google has counted, which is a measure of how much work a roofer has done rather than how well they did it. The one-and-two-star column is the one that separates them. Tick two or more rows to put them side by side, or filter by a topic reviewers mention.
A roofer showing “—” in that column has fewer than 15 ratings, which is too few for the share to mean anything: one unhappy customer out of six is 17%, and says nothing about the business.
This is not every roofer in Ontario. Our directory is built from businesses that surface in roofing searches for this area, so a large city will have more than we list. More on how we read reviews.
