Abstract A method of roof construction in which a flexible roof cover sheet is placed over the upper surface of a roof frame and is attached to that upper surface at points spaced inwardly from its outer edge, an elongated roof lock member is positioned adjacent the outer edge of the roof frame, the cover sheet is extended out over the upper surface of the roof lock member, the cover sheet is attached to the upper surface of the roof lock member at various points spaced along the length of the member, the outer longitudinal edge of the member is rotated downwardly so as to stretch the cover sheet in a lateral direction, and then the roof lock member is rigidly fastened in its rotated position so as to maintain the lateral tension in the cover sheet.
A roof lock device comprising: an elongated rigid metallic member formed as an extrusion, the greater part of the cross-section of said member having the configuration of a dipper, with a handle, an inner wall, a bottom wall, and an outer wall; said member also having a bottom wall extension which extends beyond said outer wall of said dipper and is curved upwardly and then inwardly; and which further includes an elongated wooden member inserted above said bottom wall extension and held in place by the curved portion thereof.
