Title: Original configuration retention extendible roof sections by means of universal inserts

Abstract: If any portion of a rigid surface is to be extended above the plane of the rest of the surface, then the extendible portion must be pierced. If it is necessary to keep elements from entering the resulting cuts and openings necessary to accomplish such an extension, then a weatherproof seal must be provided especially for those cuts pierced in a direction perpendicular to weathering forces and parallel to natural drawings. Since roofs are of varying shapes, there is a need for universal plates to be inserted in above mentioned cuts. These plates will provide a weatherproof seal in either extended or conventional configuration.
