What's Wrong with this Picture: Step Flashing

ANSWER: Missing "Kick-out" Flashing.
We see this type of roof/wall intersection all too often. Where is the water going? Because of the volume of water that can pour down a sloped roof, one of the most critical flashing details occurs where a roof intersects a sidewall. The roof must be flashed with step flashing. But most importantly, where the roof terminates, a “kick out” must be installed to deflect water away from the siding. Water draining behind the siding will cause damage no matter what is applied over the substrate. All siding manufacturer’s require the first piece of step flashing to divert water away from the wall. If “kick out” flashing is not installed, or installed improperly, we, as home inspectors, will include that in our report.

Roofing problem
I was this problem often when I was roofing dallas houses a few years ago. The original contractors hadn't step-flashed a single roof that I could see. I think it's probably because of the lack of consistent rainfall in that area, but whatever the reason, I didn't follow suit. Thanks for posting. This is something that is good to remember when house hunting and hiring new roofers.

I see this all the time in
I see this all the time in cheaper housing complexes, and especially with 'factory made' homes. You'd think it would be somethig simple enough to do, but cutting corners always results in shoddy work like this.
