This is actually my first post here, I've been living in my house for the past three years, it was built in the 40s. its a 1.5 story house. I havent had any problems with it, however I did notice that the roof sags quite a bit. When standing outside and looking at it from an angle, from one end to the other end, it probably sinks a good 4 inches in the middle.
Should I be concerned about this, should I try to fix this, or have it fixed. I have seen in other posts where people strengthen their roof by adding additional beams in the attick, however the problem is that, because my house is 1.5 stories, the second floor is built into the roof, my attick space only represents one third of my roof.
Any ideas on how this can be fixed without having to demolish anything in my upstairs rooms?
