We pull every roofing company we can find serving Ontario, then score each on five things: availability and service area, licensing and credentials, reputation across review sites, experience, and how they handle a real phone call. Only the top scorers make the list. Featured Providers pay for placement and are labeled; scores are never for sale.
Yes. Call or send the form and we match you with a roofing company from this list at no cost. Featured Providers may pay RatingsMatch for placement, which is why they are labeled.
Listings are earned, not bought. Claim your business at https://www.ratingsmatch.com/claim to correct details and add services. Featured placement is a separate paid option that never changes a rating.
