I had water damage in my house after a roofer stripped old shingles off and it rained. He did not have enough tarps to cover the house. He has tried to fix water spots on the ceiling, but they are still visible. Can I make him spray the entire ceiling? He also broke a decorative plastic insert on a garage door window. It cannot be replaced because they are not made anymore. What liability does he have as far as replacing the entire door?
