The word(s) "roofs" appears 210 time(s) in 207 verse(s) in Quran in Mohsin Khan translation.

(151) Do they not travel in the land, and see what was the end of those before them? They were superior to them in strength, and they tilled the earth and populated it in greater numbers than these (pagans) have done: and there came to them their Messengers with clear proofs. Surely, Allah wronged them not, but they used to wrong themselves.

(152) Then evil was the end of those who did evil, because they belied the Ayat (proofs, evidence, verses, lessons, signs, revelations, Messengers, etc.) of Allah and made a mockery of them.

(153) And as for those who disbelieved and belied Our Ayat (proofs, evidence, verses, lessons, signs, revelations, Allah's Messengers, Resurrection, etc.), and the Meeting of the Hereafter, such shall be brought forth to the torment (in the Hell-fire).

(154) And indeed We did send Messengers before you (O Muhammad صلى الله عليه وسلم) to their own peoples. They came to them with clear proofs, then, We took vengeance on those who committed crimes (disbelief, setting partners in worship with Allah, sins); and (as for) the believers, it was incumbent upon Us to help (them).

(155) And you (O Muhammad صلى الله عليه وسلم) cannot guide the blind from their straying; you can make to hear only those who believe in Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.), and have submitted to Allah in Islam (as Muslims).

(156) Thus does Allah seal up the hearts of those who know not [the proofs and evidence of the Oneness of Allah i.e. those who try not to understand true facts that which you (Muhammad صلى الله عليه وسلم) have brought to them].

(157) Only those believe in Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.), who, when they are reminded of them, fall down prostrate, and glorify the Praises of their Lord, and they are not proud.

(158) And who does more wrong than he who is reminded of the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) of his Lord, then turns aside therefrom? Verily, We shall exact retribution from the Mujrimun (criminals, disbelievers, polytheists, sinners).

(159) And We made from among them (Children of Israel), leaders, giving guidance under Our Command, when they were patient and used to believe with certainty in Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.).

(160) But those who strive against Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) to frustrate them - those, for them will be a severe painful torment.
