Trying to date structure by roof line
This is a drawing for a carriage house in my back yard that is in extreme disrepair. I'm currently getting work done on the main house so there's next to no funds available to work on this carriage house but I'd like to save it before it collapses. I'm hoping to apply for some historical funding but I have no idea how old the structure is. The earliest date on my abstract for the main house is 1881 but I don't know if the carriage house was built at the same time (or even if the main house was built then!). Someone suggested that the roof line might help to date it but I don't know what it's called and haven't been able to find a photo with a matching roof. If anyone has any information to provide on the style of this structure, I would greatly appreciate it!
