Coastal and Floodplain Construction Inspector's Practice Exam

Which materials or methods are restricted in hurricane-prone regions?

1. Use of vinyl siding

2. Use of aggregate as a roof covering

3. Fasteners for underlayment

4. Fiber cement panels

The correct answer is: Use of aggregate as a roof covering

The correct answer highlights the restriction on using aggregate as a roof covering in hurricane-prone regions because these materials can pose significant risks during high winds and severe weather conditions. Aggregate materials, typically consisting of loose stones or gravel, can be easily dislodged by strong winds. When this occurs, these materials can become dangerous projectiles, posing risks to both people and property. In coastal and floodplain construction, the emphasis is on ensuring that structures can withstand the forces of nature, particularly during hurricanes. To achieve this, roofing materials must be secured adequately to resist uplift and damage. Because aggregate does not adhere firmly and relies on weight alone, it does not meet the necessary standards for performance and safety in hurricane conditions. In contrast, the other materials and methods listed—use of vinyl siding, fasteners for underlayment, and fiber cement panels—are generally not restricted, provided they are used correctly and comply with local building codes designed for hurricane mitigation. Vinyl siding can offer flexibility and ease of installation, while fiber cement panels provide durability against harsh weather. Fasteners for underlayment must also be appropriate for wind resistance, but specific fastener types may vary based on design and engineering recommendations rather than outright restrictions.
