ABSTRACT:
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.
