Siding/ Flashing Leak

This posting is a follow up to the prior posting titled “clues to a possible roof leak”

As it turns out, the leak was the result of an improper installation of step flashing and vertical siding.

The step flashing was located beneath new flashing added by the homeowner.  The new flashing did not solve the problem

The flashing seen here was added by the homeowner to attempt to stop a leak. The gutter is notched into the vertical siding

In this image, you can see the original step flashing. The water was not diverted from the vertical siding

The start of the water damage can be seen towards the top of this image. It is the location of the end of the gutter

The image below is of the exterior after the siding was removed
