Jereme Rogers, 24, allegedly went on his roof naked early Monday morning, the Los Angeles Times reported Thursday.
The newspaper said he preached from his rooftop before Redondo Beach Police Lt. Jim Acquarelli climbed onto the roof and talked him down.
Rogers apologized Wednesday, saying he had eaten some psychedelic mushrooms that caused him to "bug out."
Rogers was hospitalized for observation and then released. Police said he may face charges, the newspaper reported.
