'House top' in the Bible

The one who is on his housetop must not come down to take things out of his house,

The one who is on his housetop must not come down or go inside to take anything out of his house,

On that day, whoever is on the housetop and his goods [are] in the house must not come down to take them away. And likewise the one who [is] in the field must not turn back

And the next day, [as] they were on their way and approaching the city, Peter went up on the housetop to pray [at] about the sixth hour.
