Moment #9: Rusted flashing along a wall line
Flashing failures are among the most common leak sources because seams and corners concentrate water flow. Rust, separation, or gaps can let water behind siding and into the roof structure. Even a small opening may route water into insulation and framing. This is often a high-value fix area because correcting flashing usually prevents repeat interior leaks. If you see corrosion, it’s worth inspecting all adjacent seams too.
