Which of the following is a benefit of proper roof ventilation?

Proper roof ventilation plays a significant role in maintaining a healthy and efficient home environment. One of the key benefits is the improvement of air quality within the home. When a roof is adequately ventilated, it allows for the exchange of stale, humid air with fresh air. This process helps to reduce the buildup of moisture that can lead to mold and mildew, which can negatively impact both the building structure and the occupants' health.

With effective ventilation, not only is the temperature inside the attic space regulated, which contributes to better energy efficiency, but it also helps to ensure that airborne contaminants and pollutants are minimized. This results in a healthier indoor living environment, making it a crucial aspect of home design and maintenance.

In contrast, the other factors mentioned are detrimental outcomes. Increased humidity can result from poor roof ventilation, which leads to moisture-related issues. Higher energy costs are often a consequence of inadequate ventilation that forces HVAC systems to work harder to maintain comfortable temperatures. Lastly, less structural integrity is associated with the potential damage caused by moisture accumulation over time, which is directly opposed to the benefits of proper ventilation.
