Must the owner of the lower floor rebuild the connecting roof if the upper floor owner refuses after the original roof collapsed?

Book of Settlement
Primary text
There are two narrations (Riwāyāt) regarding whether the owner of the lower floor can be compelled to engage in *Mubanah* (rebuilding the structure) with the owner of the upper floor when the roof separating them has collapsed and one party refuses. This situation is analogous to the ruling concerning a shared wall between two houses. Al-Shafi'i holds two opinions corresponding to these two narrations.

The issue of compelling reconstruction when the roof collapses is subjected to two principal rulings, similar to the case of a shared wall.
