I made a 4 point inspection today on a home with a metal roof. The home is 55 years old and the roof is original.
Most of the sites I see indicate that a metal roof should last between 30 and 50 years but some say the metal roof can last the lifetime of the home. I need to be able to state the remaining life of the roof.
The roof looks good in general. It is obviously old but looks to be in good condition. No signs of leakage or rust. The customer says that her husband recoats it every several years.
How would you estimate the remaining life? I was thinking about saying that it appears to have approximately 10 years left. Any suggestions?
