Gauthier Roofing and Siding is an exterior home-improvement contractor associated with 266 County Rd 42, Windsor, Ontario, N8N 2L9. The supplied business identity is supported by matching public listings for its name, phone number, address and official website. Although the address is commonly presented as Windsor in major listings, a company-authorized directory also identifies the physical location as Tecumseh; both use the same street address, postal code and telephone number.

The business documents residential exterior work that includes roofing, vinyl siding, soffit, fascia, replacement windows, exterior doors, skylights, sun tunnels, seamless eavestroughing and gutter guards. This makes it relevant for homeowners considering a single exterior project or coordinating several related upgrades. Its public materials describe service in the Greater Windsor area.

BBB lists the company as incorporated in 1974, locally started on January 2, 1968, and managed by Ron Gauthier, President. BBB currently identifies it as an Accredited Business with an A+ rating. GAF’s contractor directory lists this location as GAF Master Elite certified. That certification is specific to GAF’s contractor program; homeowners should still confirm the products proposed, system eligibility and the exact terms of any manufacturer warranty for their project.

Independent customer comments reviewed across BBB, Facebook reviews surfaced by Birdeye, HomeStars and Yellow Pages repeatedly mention communication, follow-up, workmanship, professional project handling, cleanup and timely completion. Individual experiences differ, so consumers should request a written scope, material details, timing expectations, permit responsibilities where applicable and warranty documentation before authorizing work.

FiveBest summary: A long-established Windsor-area option for documented residential roofing and exterior-envelope projects.
