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

(201) And indeed We sent Musa (Moses) with Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.), and a manifest authority,

(202) And a believing man of Fir'aun's (Pharaoh) family, who hid his faith said: "Would you kill a man because he says: My Lord is Allah, and he has come to you with clear signs (proofs) from your Lord? And if he is a liar, upon him will be (the sin of) his lie; but if he is telling the truth, then some of that (calamity) wherewith he threatens you will befall on you." Verily, Allah guides not one who is a Musrif (a polytheist, or a murderer who shed blood without a right, or those who commit great sins, oppressor, transgressor), a liar!

(203) Those who dispute about the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) of Allah, without any authority that has come to them, it is greatly hateful and disgusting to Allah and to those who believe. Thus does Allah seal up the heart of every arrogant, tyrant. (So they cannot guide themselves to the Right Path).

(204) Verily those who dispute about the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) of Allah, without any authority having come to them, there is nothing else in their breasts except pride [to accept you (Muhammad صلى الله عليه وسلم) as a Messenger of Allah and to obey you] . They will never have it (i.e. Prophethood which Allah has bestowed upon you). So seek refuge in Allah (O Muhammad صلى الله عليه وسلم from the arrogants). Verily, it is He Who is the All-Hearer, the All-Seer.

(205) Thus were turned away those who used to deny the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) of Allah.

(206) See you not those who dispute about the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) of Allah? How are they turning away [from the truth, (i.e. Islamic Monotheism to the falsehood (i.e. polytheism)]?

(207) And He shows you His Ayat (signs and proofs) (of His Oneness in all the above-mentioned things). Which, then of the Ayat (signs and proofs) of Allah do you deny?

(208) Then when their Messengers came to them with clear proofs, they were glad (and proud) with that which they had of the knowledge (of worldly things). And that at which they used to mock, surrounded them (i.e. the punishment).

(209) As for 'Ad, they were arrogant in the land without right, and they said: "Who is mightier than us in strength?" See they not that Allah, Who created them was mightier in strength than them. And they used to deny Our Ayat (proofs, evidence, verses, lessons, revelations, etc.)!

(210) That is the recompense of the enemies of Allah: the Fire. Therein will be for them the eternal home, a (deserving) recompense for that they used to deny Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.).
