12 hours of continuing education earned at a minimum of 3 roofing-related seminars are needed for application approval as well as 5 references.


RRO Application Process


The RRO exam is available online at over 1,000 conveniently located testing centers worldwide. 90 days should be allowed for processing once an application is submitted to RCI. Applications will be processed within 60 days for an additional expediting fee ($50 member/$75 nonmember).  An exam registration form will be provided to the candidate when the application has been approved.  Once registered, the candidate will be contacted by Castle Worldwide, the Internet-based testing company, to schedule an exam.

Note: RCI Educational Programs, in particular the Roofing Technology and Science programs and the Rooftop Quality Assurance program, may prove useful for anyone planning to pursue the RRO credential.


Annual Renewal


Annual renewal is required in order to maintain the RRO registration. The RRO must maintain activities as a quality assurance observer or perform job duties requiring the skills of a quality assurance observer.

An annual renewal fee is required and 10 roofing-related continuing educational hours (CEHs) must be earned each year.  All registrants are encouraged to self-report CEHs via the RCI website.  Directions for this process are available on the website at or upon request.

In the event the RRO discontinues employment in the construction industry or takes employment with a firm that provides services that cause a conflict of interest, the RRO registration will be forfeited. Registration granted by RCI shall remain its property.
