RRO practice questions - frequently asked questions

Plain answers about how RRO Exam Prep works: the exam, the questions, pricing, the free trial, and what you actually get.

No - and you should be wary of any site claiming otherwise. Every question here is original, written to mirror the style, difficulty, and judgment the real RRO exam tests. Each one comes with a plain-language explanation of why the right answer is right and the others aren't.

The RRO exam spans 6 domains: Basic Roof Science; Construction Documents; Documentation and Reporting; Field Testing Observation; Roles, Responsibilities, and Ethics; Roof Systems and Materials. Every practice question on this site is tagged to one of these domains.

The RRO exam has 75 questions and is completed in 3 hours. Our timed practice mirrors that length and pacing, so exam day feels familiar.
