Which statement best describes FM uplift ratings in relation to ASCE values?

• A. They are unrelated to ASCE standards.
• B. They do not exceed ASCE minimum values.
• C. They are higher, exceeding minimum ASCE values.
• D. They exactly match ASCE maximum values.

Answer: (C)

FM uplift ratings come from performance testing of a complete roofing system under FM Global’s protocols. These tests are designed to simulate severe wind conditions and often push beyond the basic requirements found in ASCE 7. Because the testing and evaluation focus on real assemblies and their installation details, the resulting uplift ratings typically provide a higher resistance than the ASCE minimum design values. That margin is why the best description is that FM uplift ratings are higher, exceeding minimum ASCE values. In practice, some assemblies may approach ASCE requirements for simpler cases, but FM ratings generally reflect a built-in safety margin that goes beyond the ASCE minimums.
