I have bought properties that needed roof and sometimes we would need to get on the roof to tell if there was one or two layers of shingles, but we always new how many layers before we started the job.You also said "they looked in the attic and didn't see any need for redecking" It would be blatantly clear from looking in the attic that there was more than one layer of shingles (look at the number of roofing nails sticking through the decking).As for uncovering bad roof decking during the tear off process, sometimes you just don't know until you tear off the shingles, other times its obvious from looking in the attic or walking on the roof.Sounds like this company has taken you for a ride.
