ABSTRACT:
A reusable grid system and method for in place cast forming a monolithic roof covering for a sloped roof, the roof covering having the stepped and segmented appearance of a tiled roof. The grid system includes a plurality of horizontally disposed dam bars and transversly disposed fixed and movable spacer bars therebetween which, when removably assembled atop a sloped roof, are adapted to retain monolithic poured and scraped plastic uncured concrete or the like so as to have an exposed surface which substantially duplicates a conventional tile roof after curing and removal of the grid system. The cured roof covering is thus monolithic from one eave to peak to the other eave and may include foam-filled cavities for thermal insulation and weight reduction, longitudinal segmented elastomer-filled expansion joints, formed eaves with gutter connecting means and molded edges. The grid system may also include a movable spacer bar assembly, as well as means for forming the valley between two adjacent roof sections.
