Which problem is NOT related to a building's structural integrity?

Moisture intrusion from exterior walls or the roof primarily concerns the building envelope and its ability to prevent water penetration, which can lead to various issues such as mold growth, material deterioration, and compromised indoor air quality. While moisture intrusion can negatively affect the overall condition of the building, it does not directly imply a failure of the structural components that support the weight and stability of the building.

In contrast, problems like rotting soffits, deformation causing doors or windows to bind, and foundation cracks are all indicative of issues that directly relate to the structural integrity. For instance, rotting soffits can lead to structural weakness if not addressed, deformation that causes doors or windows to bind indicates movement or shifts in the structure, and foundation cracks often signify serious underlying structural problems. Each of these issues directly impacts the stability and safety of the building's framework. Therefore, moisture intrusion, while critical to address for overall building health, does not inherently compromise the structural integrity of the building itself.
