Best roofing contractors in Ontario
These are the top 15 roofing contractors in Ontario, ranked by our earned methodology, a composite score built from ratings, review volume, recency, sentiment, and verification. Most of the businesses here handle the full range of roofing work, from emergency leak calls to full replacements, so this list ranks them as all-round roofers rather than single-service specialists.
A few businesses below also do heavy volume in one specialty. For a dedicated ranking, see our best eavestrough & gutters, best siding contractor, best skylight contractor, best gutter service, best chimney services, and best insulation contractor lists. This page orders general roofing contractors by overall composite score.
Picks are ranked by score and relevance to roofing contractor, so a lower overall score can rank higher here.
