Question: For low-slope membrane roof systems, what minimum safety factor is typically considered appropriate when determining the design uplift-resistance capacity of the roof assembly?
- A. 1.67
- B. 2.5
- C. 1.0
- D. 2.0
Correct Answer: D
According to the NRCA manual's Appendix 1 on Wind Uplift, for low-slope membrane roof systems, a minimum safety factor of 2.0 typically is considered appropriate, based on ASTM D6630. The safety factor of 1.67 applies to steel deck assemblies with steel or aluminum metal panel roof systems, not membrane roof systems.

- C. Approved fabricator
- D. Registered design professional
Correct Answer: A
Chapter 2 defines 'approved source' as an independent person, firm or corporation, approved by the building official, who is competent and experienced in the application of engineering principles to materials, methods or systems analyses. An 'approved agency' is regularly engaged in conducting tests or furnishing inspection services, and an 'approved fabricator' is approved pursuant to Chapter 17.
