Question: 1 / 400

According to IBC 2015, which type of covering is included in Class A roof assemblies?

Wood Shingles

Asphalt Shingles

Brick, masonry, or exposed concrete

Class A roof assemblies are designed to provide the highest level of fire resistance according to the International Building Code (IBC) 2015. Materials considered under Class A are those that can withstand severe fire exposure and are not easily ignited.

Brick, masonry, or exposed concrete are non-combustible materials that demonstrate significant fire resistance characteristics, making them suitable for Class A roof assemblies. These materials effectively prevent the spread of fire, which is crucial for building safety and compliance with building codes regarding fire resistance.

On the other hand, wood shingles and asphalt shingles are generally considered combustible materials and do not meet the criteria for Class A. Although metal panels can also contribute to fire resistance, the option most representative of non-combustible materials specifically detailed in Class A requirements is brick, masonry, or exposed concrete.
