House Settling

[stealth]

I know it is normal for a newer house (2011) to settle, but was wondering does it settle to the point that one of my interior doors does not want to close, and needs a lot of force if I need it to close?

Also there is a crack about 12 inches long in my roof on the main floor, is this normal. Besides these things I haven't noticed anything else.

To fix the door should I be re-aligning it or can I just sand the top corner that it is rubbing on?

The door is an easy fix, replace one of the screws on the lower hinge with a 2 1/2 or 3" wood screw, drive it through the hinge into the stud. This should suck the door in enough to make space up top. No sanding required. Post pics of the crack in the ceiling.

Thanks for the idea. I'll get some pics tonight.
