Which of the following materials is not permitted for use as roofing in a high-rise building?

Asphalt shingles
Metal panels
Clay tiles
Wood shakes

The correct answer is: Wood shakes

Wood shakes are not permitted for use as roofing in a high-rise building because they are not as durable or fire-resistant as the other materials listed. Asphalt shingles, metal panels, and clay tiles are all typically used in high-rise buildings due to their durability and fire resistance. Wood shakes may also not be able to withstand the high winds and harsh weather conditions often faced by buildings at higher altitudes. Therefore, they are not a suitable option for roofing in a high-rise building.
