Owens Corning roof data outcomes

what is the percentage of the roof data jobs you receive do you believe has a legit reason to file a claim against Owens Corning? My first job the lady lost shingles I know the shingles are supposed to withstand very high winds but a tornado practically touched down in her back yard, my second job there was a V framed in the roof two valleys had met and then the roof ran level for about 10 feet until it hit the eave and turned into a gable on both sides. My third job they said there shingles were curling up and when I got there it was the butt joints in the plywood that buckled up off the trusses. the last job I went to was poor flashing installation where the garage roof was step flashed into another gable, causing a roof leak and ridge vent was leaking
