When I went on the roof

When I went to church I run upstairs, and the door was open then I look around then I run back down and get my brother and walk back up, so I open a box door on the wall and there was some thing in it but I take it out and saw another door and unlock it. So the door was open and I crawl threw the door and I was on the roof and so do my brother and we see all the thing that is outside. But I look and saw my friend and walk down to get her and we went back to the roof. Then my other friend and her sister was there and I show them to the roof of the church then they say it was cool that I find out about that place. But we go farther to the other roof and see the inside of the room and it was high up from the ground but we went back because we can't not go any farther.
