According to the Florida Building Code, which of the following is an example of a Class A roof covering?

• A. Concrete tile
• B. Copper shingles
• C. Slate
• D. All of the above

Answer: (D)

Class A roof coverings are the highest fire-resistance category in the Florida Building Code. This rating comes from standardized fire tests that measure how well a roof assembly resists flame spread and heat transfer. Concrete tile, slate, and copper shingles all have excellent fire resistance, and when installed correctly with the proper underlayment and flashing, meet the Class A criteria. Because each listed material can attain Class A ratings, all of them qualify as Class A roof coverings. In practice, this means they are among the safer choices for fire performance, but always check the specific product rating and installation requirements for your exact assembly.
