ARCA was established in 1961 by a group of Calgary and Edmonton roofing contractors.

The association’s primary objective, then and now, is to develop comprehensive guidelines for roofing product applications to support and advance Alberta’s roofing industry.


ARCA is dedicated to supporting its members (to better serve their employees and customers) through the delivery of comprehensive technical standards, warranty program and safety initiatives and by ensuring the availability of quality education and skill development programs for industry workers.

ARCA members annually perform approximately 80% of Alberta’s Industrial/Commercial roofing applications — new and re-roof. 

Only ARCA members can issue the ARCA Warranty Certificate, which is a workmanship warranty backed by ARCA Warranty Ltd.
