According to InterNACHI, what percentage of existing decks are estimated to be completely safe?

The correct answer indicates that it's estimated that only 40% of existing decks are completely safe. This statistic reflects the concerns surrounding the structural safety and maintenance of residential decks, which can often be neglected over time. Decks face numerous challenges that contribute to safety issues, such as exposure to weather elements, deterioration of materials, insufficient structural support, and improper construction practices.

Understanding this statistic is vital for home inspectors, as it underscores the importance of thoroughly assessing deck safety during inspections. Inspectors need to check for critical factors like the condition of the wood, proper anchoring, and structural integrity to ensure that decks do not pose hazards to residents. Recognizing that a significant percentage of decks may not meet safety standards highlights the need for ongoing education and diligence in both construction and maintenance practices.

By being aware of this estimate, inspectors can better inform homeowners about the potential risks associated with decks and the importance of regular maintenance and inspections to uphold safety standards.
