Industrial & Commercial Flat Roofing
Conestoga Roofing and Sheet Metal Ltd, provides roofing systems for commercial, industrial and institutional buildings and has since 1982.
As commercial roofing contractors since 1982, the company is a preferred supplier of roofing systems across Southern Ontario because of its established expertise, fully staffed crews, administrative staff, skilled estimators and its complete equipment and mechanical fleet.

Professionalism is the Difference
At Conestoga Roofing we know that commercial roofing requires professionalism at every level. Our Project Managers and Site Superintendents are highly trained and some have achieved Gold Seal Certified, which is the Canadian Construction Associations industry’s highest level of educational and professional achievement. Our employees undergo extensive and ongoing training on roofing systems (EPDM, PVC, Modified Bitumen, Built Up Roofing, Metal Sloped Roofing) and each crew specializes in a roofing system. Only trained roofing crews work on your roof.
As members of the Ontario Industrial Roofing Contractors Association (OIRCA), we work to promote excellence in roofing construction through good business ethics, ongoing training and education, and compliance with the latest standards of occupational health and safety. We provide our customer with the highest standards of service and the finest quality of workmanship.
