What should an inspector look for when inspecting the roof structure?

When inspecting the roof structure, assessing poor attic ventilation is critical for several reasons. Adequate ventilation helps to regulate temperature and moisture levels in the attic space, which can significantly influence the overall health of the roof and the home. Poor ventilation can lead to a range of issues, including excessive heat buildup, which can cause roofing materials to deteriorate faster. Additionally, inadequate ventilation can contribute to moisture accumulation, fostering an environment for mold growth and potential rot within the roofing structure and insulation.

In contrast, while factors like pests and rodents, signs of water damage, and damaged shingles are also important aspects of a roof inspection, they do not directly relate to the foundational health of the ventilation system within the attic. Inspectors may identify these issues as secondary concerns that arise from or are exacerbated by poor ventilation. However, focusing on ventilation itself is crucial because it plays a vital role in maintaining the longevity and integrity of the entire roofing system and can prevent more significant problems from developing over time.
