Our Story
With over 20 years of hands-on roofing experience, Justin Perri founded 905 Roofing Inc. to bring a different standard to the residential roofing industry in Durham Region and the GTA.
Having seen too many homeowners get sold roofs they didn't need or receive subpar installation quality, Justin built 905 Roofing on the principles of transparency, quality, and personal accountability.
Today, 905 Roofing Inc. serves homeowners across Oshawa, Whitby, Ajax, Pickering, and the broader Greater Toronto Area. Every project is owner-supervised, and every client gets the same honest assessment — whether you need a full replacement or just a simple repair.
