Here are some photos of other areas of the same slope. These rips are everywhere on the south slope. I didn't find any on the north facing slope. I also counted over 30 creased tabs on the south slope, but now I'm beginning to wonder if they are wind related at all.

Thanks Marc. Your analysis is greatly appreciated. I will have to take a closer look at the home's foundation and look for any other signs of movement. I've been wrong more times than I would like to admit identifying causes of damage to roofs, but I've learned something new every time. In this case, I assumed wind, because it seemed like the most likely explanation considering the abundance of supporting evidence.

Thanks for the insight guys. I snipped one of the photos included in the adjusters report of an area with the tearing and tried to make the sheeting position fit the damage. It doesn't even come close to matching up. How would there be tearing in the middle of a sheet if the the decking did move? Click to Enlarge 254.44 KB

If the deck moved, wouldn't I see other signs of damage, or even deformation? How much movement would it take to tear a hole out from a shingle? I've never seen anything like this. Also, his back yard is a wide open golf course. The winds came in from that direction, and there are many creased shingles on the roof.

The last photo shows these spots circled and marked "W"

I was called to inspect a roof for hail damage that had been denied by adjuster. When I climbed up on the roof, I noticed dozens of torn through adhesive spots, mostly toward the corners of the tabs. The adjuster says "The rips are indicative of roof sheathing movement due to inadequate ventilation of the roof or improper spacing of the roof sheathing and not related to wind or hail" However, roof is ventilated correctly and there are no leaks on the roof (yet). Nothing notable in the attic. A storm with 60+ MPH wind gusts and hail had moved through the area and damaged most of the homes in the neighborhood. I'm guessing severe delamination and the sealant bonds are just really strong? Click to Enlarge 134.82 KB Click to Enlarge 59.13 KB Click to Enlarge 101.45 KB Click to Enlarge 54.28 KB
