Cincinnati's chief building inspector says shoddy construction and a new roof that added more weight are to blame for the collapse of a church on Sunday. The roof and walls of Zion Hill Baptist Church caved in about 90 minutes after the end of Sunday services. No on was hurt. A demolition crew has torn down the rest of the building. The church's pastor estimated damage at 250-thousand dollars for the building and its contents. The city has no record of a building permit for the new roof, which would have prompted an inspection. Inspector Bill Langevin says if someone had looked at the building, the church might have been warned not to add another layer of shingles.
