What indication might suggest a failure of the flashings?

The indication that might suggest a failure of the flashings is water damage around and below the flashing. Flashings are critical components in roofing and building construction that are designed to prevent water intrusion at joints and transitions in materials. When flashings fail or are improperly installed, water can seep into the underlying structures, leading to visible signs of water damage. This can manifest as stains, peeling paint, mold growth, or even structural deterioration in the areas surrounding the flashings. Observing water damage in these locations is a clear indicator that the flashings are not working as intended and require attention.

In contrast, freshly painted surfaces, warmer interior temperatures, and new landscaping do not directly indicate issues with flashings. Freshly painted surfaces could simply mean that maintenance has been performed without addressing any underlying problems, while changes in temperature or the appearance of landscaping do not provide specific evidence of flashing failures.
