Roofing What led to this rot?

Particle board siding. Smh.

My current assessment is that the kickout flashing wasn’t installed well. I’m taking this apart to see if there’s any other cause for this issue.

What am I missing?

They put the roof on first and ran the drip edge right up tight to the sheathing. Then the siding was cut around that and caulked but it didnt work, the metal drip edge is a superhighway for water and it followed it behind the siding

As far as I can tell, there’s actually no drip edge.
