Coastal and Floodplain Construction Inspector's Practice Exam

What is the restriction on using aggregate as surfacing for roof covering in hurricane-prone regions?

1. It is allowed as a primary covering

2. It is not permitted as a roof covering

3. It is only permitted with additional materials

4. It requires special approval

The correct answer is: It is not permitted as a roof covering

Using aggregate as a surfacing for roof covering in hurricane-prone regions is generally not permitted as it poses a risk during high winds. When a hurricane strikes, strong winds can lift loose aggregate, turning it into projectiles that can damage other structures and create hazardous conditions. The prevailing codes and standards for roofing in these regions prioritize the use of roof coverings that are more secure and resistant to wind uplift to enhance safety and minimize damage. In hurricane-prone areas, the emphasis is on roofing materials that provide effective wind resistance, ensuring stability and reducing the likelihood of material displacement. Therefore, the guideline clearly limits the use of aggregate for roof surfacing, focusing on materials that can better withstand the severe weather conditions typical in such environments.
