Mission Statement: The mission of IIBEC is to advance the profession of building enclsoure (roofing, waterproofing and exterior wall) consultants.

Since 1983, IIBEC’s, formerly RCI, Inc., Consultant members have offered unbiased design, repair planning, quality assurance observance, legal testimony, and general roofing and other building enclosure management services. IIBEC’s Consultant members adhere to a strict code of ethics that offers unprejudiced service without affiliation with any product or manufacturer. Current membership is over 3,600. IIBEC boasts an international constituency residing across the United States, Canada, Australia, the West Indies, Europe, and Asia.

The association presents educational programs, in-person and online, designed to demystify and explain the practical application of roofing and waterproofing technology and sound building enclosure theory. A monthly journal (Interface), a monthly newsletter (IIBEC Newsfeed), and international, regional, and chapter events provide interactive forums for information exchange and networking.

The Registered Roof Consultant (RRC®), Registered Waterproofing Consultant (RWC®), Registered Exterior Wall Consultant (REWC®), Registered Roof Observer (RRO®), and  Certified Building Enclosure Commissioning Provider (CBECxP®) coming in Spring 2020 programs distinguish professionals with proven standards of education, experience, and ethics.

The RCI-IIBEC Foundation (U.S.) and the RCI Foundation Canada are tax-exempt entities, organizationally independent of the association, and support research and educational efforts of the industry.
The IIBEC mission is realized by a professional staff headquartered in Raleigh, North Carolina and through the efforts of a volunteer board of directors, numerous committees and its individual members across the globe.
