This could be because the shingles seal was weaker on the pipe boots allowing wind to get under and bed the shingle back.
As you can see here more damaged shingles.
There are several areas that are wind damaged which we marked with chalk so that the homeowner could see the damage.
After our complete inspection we noted that there were 24 total wind damage shingles and the homeowner has filed a claim with his insurance claim.
As you can see these shingles shouldn't lift up but do. This is because the shingles have become cracked and the tar strip is not sticking anymore.
The front of the roof took the brunt of the damage but the back side still showed some damage as well.
