About Us


Trust Century for Excellence in Roofing & Siding in Ottawa

Century Roofing and Siding was established in 1980 to provide exterior renovation, maintenance and repairs to home and business owners in and around the Ottawa area. This two-generation family business started four decades ago when two brothers, Anthony and John Barresi, learned the trade under the tutelage of our father, who happens to be the founder of the company.

Today we credit our current success to the perseverance and skill of our father, who taught us the value of excellent workmanship, customer service, honesty and integrity. Our dad had a great amount of pride in his company, something he decided to create after he moved to Canada from Italy in 1965 with nothing but the clothes on his back. He taught his sons the value of a solid work ethic, showing them we could succeed at anything we set their minds to, hoping to someday see his sons continue his legacy. We have!
