n.

Old English hrof “roof, ceiling, top, summit; heaven, sky,” also figuratively, “highest point of something,” from Proto-Germanic *khrofam (cf. Old Frisian rhoof “roof,” Middle Dutch roof, rouf “cover, roof,” Dutch roef “deckhouse, cabin, coffin-lid,” Middle High German rof “penthouse,” Old Norse hrof “boat shed”).

No apparent connections outside Germanic. “English alone has retained the word in a general sense, for which the other languages use forms corresponding to OE. þæc thatch” [OED]. Roof of the mouth is from late Old English. Raise the roof “create an uproar” is attested from 1860, originally in U.S. Southern dialect.
