My husband and I are wanting to buy a home. This home is one year old. Yet we noticed several (probably 10 or so) places on the roof that sag - very visible from just looking.
a. What would cause this?
b. Can it be fixed.
c. Is it a sign of faster need to replace. (it certainly isn't attractive - that's for sure) but is it a structural problem?

just a guess but i would say they have trusses on two foot centers and used 7/16 osb board instead of 1/2 or 3/4 plywood.for only one year old that is pretty drastic,oh probably didnt use the clips for the deck either .like i said thats just a guess from here without being able to see it.might be a problem if you get snow might not hurt any thing if not but i would think alot about buying that house cause who knows what else was done cheaply

Yes, it is structural problem, and expensive to fix. Better walk away from this one.

or..........

It could be a cut rafter roof with no perlin bracing and no additional braces for load. This would easily cause a sag like you describe. But........this would be the easiest to fix.............
