This area is missing a shingle due to delamination. Delamination is the process in which one shingle comes apart and breaks into 2 pieces. The top section and the bottom section
More areas of delamination this is due to the high nailed nails. Here are a few pictures of the nails being too high
Rusting nails are also signs of water under the shingles, and this is due to the missing shingle just above this area.
The small holes in the ridge cap are due to the crack in the ridge cap shingles.
Lots of nail pops on hips and through the roof.
