Florida Building Code Practice Exam

In a high-velocity hurricane zone, the installation of asphalt shingles is limited to what roof mean height?

1. 20'

2. 33'

3. 38'

4. 48'

The correct answer is: 33'

In a high-velocity hurricane zone, the Florida Building Code sets specific regulations to ensure that roofing materials can withstand the harsh conditions posed by hurricanes, including high winds and flying debris. When it comes to asphalt shingles, the code limits their installation to a mean roof height of 33 feet. This requirement is based on the understanding that as the height of the roof increases, the potential for wind uplift and other stressors on the roofing material also increases. Therefore, the limit of 33 feet is in place to ensure the performance and safety of asphalt shingles in such environments. This height consideration is important for maintaining the integrity of the structure during extreme weather events, where traditional roofing materials might fail under the enhanced forces experienced at greater elevations. Options beyond this height may not be adequately designed to perform under the extreme conditions typical of hurricane zones, thereby leading to potential failures in the roofing system and compromising the safety of the building. This understanding emphasizes the critical nature of adhering to established building codes in high-risk areas.
