The plural is “roofs,” not *”rooves.” But the mistaken plural occurs with some frequency — e.g.:
o “But the view from the classroom (which his son uses to run a cramming school) is of rooves [read 'roofs'] and television aerials, so the farmers’ cause seems already lost.” “The Last of the Left,” Economist, 4 Feb. 1995, at 32.
o “The birds scoured yards for food, roosted in eaves and pooped liberally on tile rooves [read 'roofs'].” Susan M. Loux, “Dairy Pigeons Spot New Targets,” Press-Enterprise (Riverside, Cal.), 20 July 1996, at B1.
o “Now Violeta shows off snapshots of Puerto Rico that evoke dusty palm trees and hot clay rooves [read 'roofs'] and heavy blue skies.” Diana Michele Yap, “‘Met Violeta, Liked Her a Lot,’” Providence J.-Bull., 10 Oct. 1996, at H8.
