<p>An assemblage of sheet metal roof covering pieces is utilized in a novel process to recover and stiffen a deteriorated roof (ERC) without the necessity for extensive removal of the original roof covering, the deteriorated roof structure (ERC) further stiffened by ribs (111) that also serve to fix in interlocking engagement the sheet metal roof covering pieces. Including in the assemblage are interlocking valley pans (21) that are sequentially compressed between the ribs (111) and then fastened with the valley pans (21), then bridged by curved sheet metal caps (31) that are also interlocked. The resulting structure has the pleasing appearance of an Oriental tile roof.</p> |
