may be considered Class A without testing Correct answer-Per IBC, Copper Sheet Roofing(min.
16oz) over combustible roof deck
TRUE. They are not compatible. (PVC is made up of ethylene and chlorine, and more durable than
EPDM) (Perlite roofing is often used for insulation) Correct answer-Perlite and PVC membranes
Primarily comes in black, has poor solar reflectivity, may be laminated with an additional layer.

gravel" roof?
FALSE. The Architect will almost always be held vicariously liable. Correct answer-The building
owner will almost always be held vicariously liable when a design's nonconformance with the
building code exists.
Solid deck (solid sheathing/ solid decking) Correct answer-A _____ deck would be considered as a
must in seismic activity, hurricane and tornado regions.
can increase the roofs insulation value Correct answer-A felt interlay

roof is:
Per NFPA 5000, there are specific requirements for buildings roof assemblies in that they need to be
hail-resistant in specific hail-prone regions. Correct answer-Referring to the NFPA, there are
requirements spelled out for buildings' roof assemblies in hail-prone regions:
there is heavy traffic on the roof. They are thicker. Correct answer-Built-up roofs are suitable when
NEVER allow the installation of a new roof system over existing roof systems with wet insulation.
Correct answer-Model building codes
