Quality Workmanship & Attention to Detail
Guaranteed Roofing is a family owned and operated roofing company in Schomberg that prides itself not only on our expertise in the trade but also in our ability to maintain customer satisfaction through our attention to detail. We have always been complimented on the quality of our workmanship, customer satisfaction and how clean our job sites are left after we have completed our work. We are often told that if not for the new roof, the homeowners couldn’t even tell we were there! 

Our Positive Reputation Speaks for Itself
Guaranteed Roofing has grown a lot over the past 25 years. However, it is our goal to never lose that small business approach, where it is quality NOT quantity and to maintain a personal work rapport with all of our clients. We are fully insured and Workplace Safety and Insurance Board (WSIB) covered, as well as a member of our local chamber of commerce. At Guaranteed Roofing, we feel our positive reputation and professional certifications speak for themselves.
