To find yourself on a roof in a dream denotes unbounded success. To become frightened and think you are falling, signifies that, while you may advance, you will have no firm hold on your position.

To see a roof falling in, you will be threatened with a sudden calamity.

To repair, or build a roof, you will rapidly increase your fortune.

To sleep on one proclaims your security against enemies and false companions. Your health will be robust.
