To dream of your roof symbolizes your self-awareness vis-a-vis your subconscious feelings. It symbolizes a protection of your thoughts and beliefs. It is also a facade for how you perceive yourself.
To dream you are on a roof signifies euphoria from your achievements. To dream of falling off the roof suggests losing your control and having a weak standing at an advanced phase in your life.
To dream of a leaky roof suggests negative influences, distractions, and irritations. It may also suggest coming across new ideas and information. On the other hand, it may stand for a message that is finally getting across to you. This may be particularly true in the case of someone who is trying to shove his or her opinions down your throat.
To dream that the roof is caving in suggests a failure to live up to your ideals.
