The correct answers are The roof of the house was covered in bats. and The house's roof was covered in bats.
For inanimate objects (things that aren't alive, like a house), it is very common and natural to use an "of" phrase (the roof of the house).
However, using 's (the house's roof) is also grammatically correct and widely used in modern English. You must include the apostrophe before the "s" because "house" is singular!
