The Roofing (C-39) Examination is divided into five major sections, which are 1. Planning and Estimating 2. Job Site Preparation for Roofing Projects3. Low Slope Roofing Projects 4. Steep Slope Roofing Projects 5. Worker and Job Site SafetyTechnical questions are almost always based on the NRCA recommendations. Still, you need to know the CA codes (in particular Title 24 and Title 8 of the California Code of Regulations CCR – T8 specifies many requirements for fall protection so you must know the requirements inside and out). We create these supplemental self-practice test questions module referencing the principles and concepts currently valid in the roofing trade. Each question comes with an answer and a short explanation which aids you in seeking further study information.
