(KMOV) -- Structural engineers are trying to figure out what caused a roof collapse at a St. Louis area church.
It happened around 8:00 p.m. on Tuesday at Faith Church in Fenton, Missouri.
The church was hosting a youth service at the time of the collapse.
About 20 students and a couple of adults were in the building when one of the adults noticed some tiles falling from the ceiling. The leaders decided to get everyone out of the building. Minutes later, the roof collapsed.
No one was injured in the collapse.
Authorities have deemed the 30-year-old building uninhabitable.
