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

(211) Verily, those who turn away from Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc. by attacking, distorting and denying them) are not hidden from Us. Is he who is cast into the Fire better or he who comes secure on the Day of Resurrection? Do what you will. Verily He is All-Seer of what you do (this is a severe threat to the disbelievers ).

(212) And among His Ayat (proofs, evidence, lessons, signs, etc.) is the creation of the heavens and the earth, and whatever moving (living) creatures He has dispersed in them both. And He is All-Potent over their assembling (i.e. resurrecting them on the Day of Resurrection after their death, and dispersion of their bodies) whenever He wills.

(213) And those who dispute (polytheists with Our Messenger Muhammad صلى الله عليه و سلم) as regards Our Ayat (proofs, signs, verses, etc. of Islamic Monotheism) may know that there is no place of refuge for them (from Allah's punishment) [Tafsir At-Tabari].

(214) And were it not that mankind would have become of one community (all disbelievers, desiring worldly life only), We would have provided for those who disbelieve in the Most Gracious (Allah), silver roofs for their houses, and elevators whereby they ascend,

(215) And adornments of gold. Yet all this (i.e. the roofs, doors, stairs, elevators, thrones of their houses) would have been nothing but an enjoyment of this world. And the Hereafter with your Lord is (only) for the Muttaqun.

(216) And indeed We did send Musa (Moses) with Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) to Fir'aun (Pharaoh) and his chiefs (inviting them to Allah's religion of Islam) He said: "Verily, I am a Messenger of the Lord of the 'Alamin (mankind, jinn and all that exists)."

(217) But when he came to them with Our Ayat (proofs, evidence, verses, lessons, signs, revelations) behold, they laughed at them.

(218) And when 'Îsa (Jesus) came with (Our) clear Proofs, he said: "I have come to you with Al-Hikmah (Prophethood), and in order to make clear to you some of the (points) in which you differ. Therefore fear Allah and obey me.

(219) (You) who believed in Our Ayat (proofs, verses, lessons, signs, revelations, etc.) and were Muslims (i.e. who submit totally to Allah's Will, and believe in the Oneness of Allah - Islamic Monotheism).

(220) These are the Ayat (proofs, evidence, verses, lessons, revelations, etc.) of Allah, which We recite to you (O Muhammad صلى الله عليه و سلم) with truth. Then in which speech after Allah and His Ayat will they believe?
