And finding no way to bring him in because of the crowd, they went up on the roof and let him down on his bed through the tiles into the middle of the crowd before Jesus. Bible

“through the tiles.” Mark says that the men “uncovered the roof where he was, and...dug through it.” Although the average house had a roof of packed dirt, this house was in Capernaum, which had a large Roman influence, and so it is quite possible that the roof had a cap of tile over the dirt and beams. Thus, the men would “uncover” the roof and then dig through it.
