Truss sheathing help needed

[Ray Farruggia]

I am a home inspector and I ran into a problem that I can find no info about, and hope someone here can direct me to the right place.

I just inspected a house with an apparent window leak problem. After many false starts, I located the source of water penetration. After pulling up the starter course and first row of roofing shingles, I saw that the roof sheathing was about 1 1/2" short of the fascia. Water had been splashing/spilling out of the gutter and getting through this opening, then behind the siding, and discharging around the window.

My question is, why was the sheathing short? I suspect poor quality workmanship, but could it have possibly been designed that way? or could it be a condition that occured over time, like some wacky case of truss uplift?

Any thoughts, advice or direction is truly appriciated. Thanks in advance, Ray

Did this happen to have box soffits?
Unlikely from truss uplift or any structural movement. I'm thinking they started their sheathing on the 2nd row and didn't measure up correctly for the placement.
Grumpy may have seen something like this in his travels also.

Thanks for the speedy reply Rich.
Nope, no box soffits.
Doing a lot of researh on truss deign, havent found anything remotely similar yet, so all signs point to poor workmanship.
