Narrative:

Contact with flat roof on vacant building. Descent to landing behind vacant school, vented a little early. Flight was in congested area. If flight path 2 ft higher would not have made contact. Incident was due to pilot judgement, have set up plan to practice approach and lndgs at least once a week for 4 weeks, simulated tight lndgs. Also to be more aware of the area. This is the only property contact in 4 yrs of ballooning.
