The word(s) "roofs" appears 38 time(s) in 37 verse(s) in Quran in Muhammad Pickthal translation.

(11) For that cause We decreed for the Children of Israel that whosoever killeth a human being for other than manslaughter or corruption in the earth, it shall be as if he had killed all mankind, and whoso saveth the life of one, it shall be as if he had saved the life of all mankind. Our messengers came unto them of old with clear proofs (of Allah's Sovereignty), but afterwards lo! many of them became prodigals in the earth.

(12) When Allah saith: O Jesus, son of Mary! Remember My favour unto thee and unto thy mother; how I strengthened thee with the holy Spirit, so that thou spakest unto mankind in the cradle as in maturity; and how I taught thee the Scripture and Wisdom and the Torah and the Gospel; and how thou didst shape of clay as it were the likeness of a bird by My permission, and didst blow upon it and it was a bird by My permission, and thou didst heal him who was born blind and the leper by My permission; and how thou didst raise the dead by My permission; and how I restrained the Children of Israel from (harming) thee when thou camest unto them with clear proofs, and those of them who disbelieved exclaimed: This is naught else than mere magic;

(13) Proofs have come unto you from your Lord, so whoso seeth, it is for his own good, and whoso is blind is blind to his own hurt. And I am not a keeper over you.

(14) Such were the townships. We relate some tidings of them unto thee (Muhammad). Their messengers verily came unto them with clear proofs (of Allah's Sovereignty), but they could not believe because they had before denied. Thus doth Allah print upon the hearts of disbelievers (that they hear not).

(15) Hath not the fame of those before them reached them - the folk of Noah, A'ad, Thamud, the folk of Abraham, the dwellers of Midian and the disasters (which befell them)? Their messengers (from Allah) came unto them with proofs (of Allah's Sovereignty). So Allah surely wronged them not, but they did wrong themselves.

(16) We destroyed the generations before you when they did wrong; and their messengers (from Allah) came unto them with clear proofs (of His Sovereignty) but they would not believe. Thus do We reward the guilty folk.

(17) Then, after him, We sent messengers unto their folk, and they brought them clear proofs. But they were not ready to believe in that which they before denied. Thus print We on the hearts of the transgressors.

(18) Hath not the history of those before you reached you: the folk of Noah, and (the tribes of) A'ad and Thamud, and those after them? None save Allah knoweth them. Their messengers came unto them with clear proofs, but they thrust their hands into their mouths, and said: Lo! we disbelieve in that wherewith ye have been sent, and lo! we are in grave doubt concerning that to which ye call us.

(19) With clear proofs and writings; and We have revealed unto thee the Remembrance that thou mayst explain to mankind that which hath been revealed for them, and that haply they may reflect.

(20) And verily We gave unto Moses nine tokens, clear proofs (of Allah's Sovereignty). Do but ask the Children of Israel how he came unto them, then Pharaoh said unto him: Lo! I deem thee one bewitched, O Moses.
