I have a project were the AHJ did some field fire testing on a canopy and decided that since a sample the thermoplastic ROOF membrane "sustained flame after an exposure to flame", sprinklers were required in the canopy.
I thought the canopy meet the exceptions of 8.15.7.3 (2). I didn't think the material on top of the canopy was a consideration. This canopy is constructed with a EIFS (FSI <25) attached to 2 layers of exterior gypboard attached to the bottom of 2x12's(joist spaces @22ft^3) with OSB and built up TPO roofing on top. Am I wrong in thinking that we are protecting the canopy from ignition sources underneath it, not above it?
