Exam & certification information
About the Roofer Red Seal exam.
The published examination has 125 four-option multiple-choice questions, a four-hour writing time and a 70% passing mark. Our two full forms match that length, time and published task distribution. The questions are independently developed.
Review the range of roofing systems in the national standard, including those outside your regular work. Manufacturer requirements remain system-specific.
Your provincial or territorial authority determines eligibility, fees, booking and permitted references. This study package does not register you for the official exam or confer certification.
