Registered Roof Observer - RRO ®  

Those who desire to become Registered Roof Observers must fulfill certain requirements. These requirements include completion of an application, agreement to abide by the RCI Code of Ethics, and earning a satisfactory score on a written examination.


RRO Application Process


The RRO exam is available online at over 1,000 conveniently located testing centers worldwide. Once applications are submitted to RCI, allow 90 days for processing.  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 the registration form and exam fee have been received, the candidate’s information will be conveyed to Castle Worldwide, the Internet-based testing company.  The applicant will then be contacted by Castle to schedule the testing session. 

Online testing is offered on demand, to approved candidates, based on individual testing center hours and availability. Consult for testing center locations.

RRO Exam


The exam is multiple-choice and tests knowledge of roof observation principles for the following types of roofing systems: built-up, single-ply, asphalt shingle, wood, sprayed polyurethane foam, tile, metal and slate. The online exam is four hours long.

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.
