A roof having an insulating blanket of plastic foam covered by a protective sheath made up of a shell of reinforced concrete covered by a weather-impervious rubbery textured membrane. The membrane and the shell are married together in the sheath, the shell providing load bearing strength and the membrane protecting the shell and preserving its properties. The shell adheres tenaciously to the insulating blanket and the membrane to the shell. In a preferred construction, the sheath forms a protective bonnet having a girdle surrounding the eaves and verge further anchoring the roof covering to the superstructure of the building. Shingles of special construction preferably make up the insulating blanket. Special cement and latex binder compositions are disclosed for the shell and membrane respectively.

A roofing shingle, comprising, an elongated integral wedge-shaped body of closed cell synthetic plastic foam of density from about 1 to about 3 lbs per cubic foot having a substantially rectangular planar upper surface, a substantially rectangular planar under surface, opposed substantially triangular planar side surfaces and leading and trailing rectangular planar end surfaces, said body tapering from a major thickness adjacent the leading end to a minor thickness adjacent the trailing end which constitutes a tongue, said body having each side shaped to interfit with a complementary side of an adjacent shingle, the leading end being shaped to interfit with the trailing end of an adjacent trailing shingle, the undersurface being adapted to lie flat on a planar roof deck as a continuation of the undersurfaces of companion shingles at each side and at its trailing and leading ends, the body being provided with a side recess extending inward from and along the entire edge of one side surface and extending upward from and along the adjacent part of the edge of the undersurface, the body being provided with an end recess extend-inward from and along a major portion of the edge of the leading surface and upward from and along the edge of the undersurface, the body being provided, at the other side with a flange extending outward from and along a major portion of the edge of the other side face and upward from and along a major portion of the edge of the undersurface, said flange having an end face forming a continuation of a face of the end recess at one end and at the other end having a part including a continuation of the top, bottom and trailing end faces, the side recess being shaped to receive in a mating relationship, a flange of the type defined on the side of a similar flanking shingle and said flange being shaped to receive the side recess of a flanking shingle with the side surfaces of the respective shingles abutting whereby each side surface abuts that of an adjacent shingle and the upper and undersurfaces of the shingle and its flanking shingles form a substantially continuous planar surface, the end recess being adapted to receive the tongue of a similar shingle whereby the leading end surface is adapted to form a substantially unbroken surface continuing at an abrupt angle to the upper surface of the trailing shingle.
