Professionally Roofing  
Since 1964!
Since 1964, the Ontario Industrial Roofing Contractors 
Association (OIRCA) has been the voice of the industrial/
commercial/institutional (ICI) roofing industry in Ontario. The 
Association is a group of professional roofing contractors, roofing 
product suppliers, building science consultants and industry 
professionals. The mission of the organization is to assure through 
accountability, excellence in roofing construction. 
The OIRCA and its members serve the construction industry 
through committees that specialize in roofing technology, industry 
occupational health and safety, risk management, apprenticeship, 
education, labour relations and membership. This work is intended 
to not only enrich our member companies but the industry as  
a whole.
New member applicants do not secure membership by simply 
completing an application and submitting it with payment. Rather, 
those companies must meet specific criteria and submit to a 
thorough evaluation that includes on-site workmanship inspections 
as well as an independent safety audit. All members are subject 
to an annual performance audit to certify compliance with the 
association’s standards. 
OIRCA provides the construction industry with a means to 
prequalify roofing contractors. By specifying an OIRCA member, 
the purchaser of roofing services is assured of competent and 
competitive roofing practices. As a self-policing organization, the 
OIRCA stands behind the principles and ethics of the association 
and expects each member to do the same.
The OIRCA Vision...
The only source for professional ICI roofing contractors in Ontario.
The OIRCA Mission...
To assure through accountability, excellence in roofing construction.
