Why homeowners trust these rankings

200 contractors, one consistent scorecard

Every roofing contractor in Ontario, from Roof Repair to Sheet Metal and Waterproofing specialists, is measured the same way, so comparisons across categories actually mean something.

An average of 4.74 stars, and we show the gaps too

With fair pricing (34 mentions), professional crews (18) and quality workmanship (15) as the top praise themes, and only a handful of complaints like slow post-job follow-up, you see the full picture, not a curated highlight reel.

Editorial oversight, not an algorithm alone

Research Lead Marcus Ramos maintains the ranking methodology, and the database is refreshed monthly from published review data and public business records, never paid placements.

How we score every roofing contractor

One published rubric scores each business 0–100 from recent public Google reviews: rating, review volume, recency, sentiment, and profile completeness. No pay-to-rank, no edited reviews.

  • Sentiment synthesised from real reviews, not republished
  • Google-verified businesses clearly marked
  • Refreshed regularly so scores stay current
