Hi all, this is my first post and I'm glad to have found your site! We are in the process of buying a 42 year old home (the heating system is approximately 23 years old), and our inspector stated this in his report: "We noted rust damage/deterioration to the gas flue pipe at the roof.....We identified extensive damage to the gas flue pipe, as viewed from the attic." Our inspector, who has been in business for 20 years, said he can count on two fingers how many times he's seen the bad condition of the flue pipe in the attic. I have attached pics (I hope!), and am sorry they couldn't be more fully detailed. The sellers said that they had an HVAC guy come out to look at it and he doesn't think it's an issue, so the sellers don't want to take care of it. I'm obviously concerned for my family's safety, and am doing as much research as possible on this. What are your opinions? Thanks so much! Click to Enlarge 28.94 KB Click to Enlarge 25.71 KB
