A new conical roof building method provides flat plates having straight abutting edges and curved outer edges. The plates are placed horizontally edge to edge except for a sectoral opening. The plates are welded together to form a flat disc-shaped blank, leaving an open sector of the blank. Radial supports are welded to a top of the disc-shaped blank. A center of the disc-shaped blank is lifted, forming a conical-shaped structure, closing and abutting edges of the open sector and touching edges of the formerly open sector are welded together, completing the forming of the conical roof.

The invention claimed is: 1. Apparatus comprising a conical roof, the conical roof being constructed as generally triangular plates having straight abutting edges and curved outer edges, the abutting edges of the plates being welded together and forming the conical roof, radial supports welded to a top of the conical roof, a center of the conical roof being raised to force together the abutting edges of the plates forming a conical-shaped structure, completing the conical roof, further comprising a compression ring welded to upper and inward portions of the radial supports after completing the conical roof.
