When inspecting exterior flashings, what is often an unseen factor?

When inspecting exterior flashings, the condition of the flashing itself can often be an unseen factor that may not be immediately visible during an inspection. Flashing is critical in directing water away from vulnerable areas of a building, such as joints, seams, and penetrations. Damaged, corroded, or improperly installed flashing can lead to water intrusion and structural issues over time, making its condition essential to the overall integrity of the building.

While the presence of insulation, type of building materials, and external paint condition are all important aspects of a building's exterior, they do not directly address the effectiveness of the flashing. The condition of the flashing is crucial because issues here can lead to significant hidden damage that might not be apparent until it manifests as leaks or water damage inside the building. Therefore, focusing on the flashing's condition during an inspection is essential to prevent future problems related to water entry.
