thank you, that seems to be what is going to happen. They will remove the nails and repair with roofing cement. It is very helpful for me to know that I can insist they not leave nails in our roof. My husband and I (both retired) bought a 30 year roof bc we never want to have to repair or replace this roof again. I always try to be nice and accomadating to workers but I don't want to be someone's fool. thanks so much and God bless, andrea
