Which item is not listed as a common weak link in roofing systems?

• A. Overly bright color of edge metal.
• B. Fastener pull-out
• C. Inadequate perimeter attachment
• D. Adhesive voids

Answer: (A)

Wind uplift performance centers on how loads are carried through the roof system's connections and bonds. Fastener pull-out happens when the fastener can’t resist the withdrawal forces, often due to inadequate substrate or undersized screws. Inadequate perimeter attachment is critical because uplift forces concentrate at edges and perimeters, so weak attachments there compromise the whole assembly. Adhesive voids create unbonded spaces that weaken the bond line, reducing the roof’s ability to transfer loads and seal against water.

An overly bright color of edge metal does not represent a structural or wind-related weakness in the roof system. It’s more related to solar reflectance, thermal performance, and aesthetics, not to the load path or failure modes that govern wind uplift.
