Common questions

How are these Ontario roofing contractors ranked?

We rank roofing contractors using our own editorial assessment of each one's reputation and how established it is in the community, drawn from publicly available signals and local knowledge. Providers with a weak reputation are kept out of the top of the list. This is an independent guide — businesses don't pay to be ranked (a paid placement, if any, is always labeled "Featured").

How much does a new roof cost in Ontario, CA?

A full roof replacement in the Inland Empire typically runs $8,000 to $20,000+ depending on size, materials (asphalt shingle vs. tile), and roof complexity. Repairs are far less. Because it's a major job, get at least two or three written estimates and confirm the contractor's CSLB license before signing.
