The Slate Roof House was a mansion that stood on 2nd Street north of Walnut Street in Philadelphia, Pennsylvania, from about 1687 until its demolition in 1867. Built for Barbadian Quaker merchant Samuel Carpenter, the house occupied a small hill overlooking the Delaware River. It was built of brick in the Jacobean style with its façade featuring two projecting wings that flanked a recessed central entrance. The house was notable for its large size as well for its slate roof, which was a rarity in early Philadelphia.
