Broken Industry

Roofing in Ontario is unregulated – best practice isn’t common practice. Broken promises and substandard workmanship are commonplace.

Be Informed

Our main focus is the education and empowerment of our clientele. The roofing industry misleads. We’ll give you a peak behind the curtain.

Better Decisions

Trust is often misplaced when we base our decisions on poor information and faith. Our focus is help you make better decisions, based on fact.

Why Work With Us?

At 123 Roofing, our mission is to blend experienced and accredited roofing application with business practices that are diligent, organized and professional. We do this with the intention of providing industry-leading best practices in all facets of what we do.

With many years of experience, we are your trusted roofing partner in the GTHA.
