What is a potential consequence of inadequate ventilation in a roof system?

Inadequate ventilation in a roof system can lead to reduced energy efficiency. When ventilation is insufficient, it can cause temperature imbalances in the attic or roof space, which may result in overheating during the summer and excessive heat retention during the winter. These temperature fluctuations can lead to higher energy consumption as HVAC systems work harder to maintain comfortable indoor temperatures. Moreover, poor ventilation can trap moisture, contributing to mold growth and structural issues, which further degrade energy efficiency. By ensuring proper ventilation, a roof system can help maintain optimal temperatures and improve overall energy efficiency in a building.
