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 spacer bars 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 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.
