What is Quality Assurance (QA) in roofing?

• A. The contractor's responsibility to perform.
• B. The consultant's responsibility, including periodic observation and reporting deviations.
• C. A legal requirement for warranties.
• D. An on-site safety program.

Answer: (B)

Quality Assurance in roofing means the independent, systematic verification that the roof installation complies with the contract documents, design intent, and applicable standards. The consultant or owner typically holds this role, conducting periodic on-site observations and documenting any deviations or nonconforming conditions so they can be corrected before progress continues. This oversight provides objective confirmation that workmanship, materials, and installation procedures meet the required expectations, which supports performance, durability, and warranty considerations. It’s different from quality control, which is the contractor’s internal checks to ensure their work aligns with specs, and it’s not about safety programs or warranty requirements themselves.
