Book updated in October 2020. The NC roofing license exam covers the installation and repair of roofs and decks on residential, commercial, industrial, and institutional structures requiring materials that form a watertight and weather-resistant surface. Even though there are code related questions that are state specific (based on NC building codes and the IBC), technical questions are almost always based on the NRCA/OSHA recommendations. We create these supplemental self-practice test questions module referencing the principles and concepts currently valid in the corresponding trade. Each question comes with an answer and a short explanation which aids you in seeking further study information. These questions are intended as supplementary study material for fundamental knowledge establishment. They are NOT actual past-paper questions. You should use this product together with other study resources for the best possible exam prep coverage.
