The word(s) "roof" appears 247 time(s) in 241 verse(s) in Quran in Mohsin Khan translation.

(191) And those who strive against Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.), to frustrate them, they will be brought to the torment.

(192) And when Our Clear Verses are recited to them, they say: "This (Muhammad صلى الله عليه وسلم) is naught but a man who wishes to hinder you from that which your fathers used to worship." And they say: "This (the Qur'an) is nothing but an invented lie." And those who disbelieve say of the truth when it has come to them (i.e. Prophet Muhammad صلى الله عليه وسلم when Allah sent him as a Messenger with proofs, evidence, verses of this Qur'an, lessons, signs, etc.): "This is nothing but evident magic!"

(193) Say (O Muhammad صلى الله عليه وسلم): "Tell me or inform me (what) do you think about your (so-called) partner-gods to whom you call upon besides Allah? Show me, what they have created of the earth. Or have they any share in the heavens? Or have We given them a Book, so that they act on clear proof therefrom? Nay, the Zalimun (polytheists and wrong-doers) promise one another nothing but delusions."

(194) By the Qur'an, full of wisdom (i.e. full of laws, evidence, and proofs),

(195) And never came an Ayah from among the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) of their Lord to them, but they did turn away from it.

(196) Yes! Verily, there came to you My Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) and you denied them, and were proud and were among the disbelievers.

(197) To Him belong the keys of the heavens and the earth. And those who disbelieve in the Ayat (proofs, evidence, verses, signs, revelations, etc.) of Allah, such are they who will be the losers.

(198) None disputes in the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) of Allah but those who disbelieve. So let not their ability of going about here and there through the land (for their purposes) deceive you [O Muhammad صلى الله عليه وسلم, for their ultimate end will be the Fire of Hell]!

(199) It is He Who shows you His Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) and sends down (rain with which grows) provision for you from the sky. And none remembers but those who turn (to Allah in obedience and) in repentance (by begging His Pardon and by worshipping and obeying Him Alone and none else).

(200) That was because there came to them their Messengers with clear evidence (proofs and signs) but they disbelieved (in them). So Allah seized them (with punishment). Verily He is All-Strong, Severe in punishment.
