A ridge seal assembly has a first molded unit having a flat nailing portion and a portion to conform to pan and cap areas of roof tiles, the nailing portion and the cover portion are contiguous and may have openings. The nailing portion has a first straight edge away from the tile-cover portion. A second like unit has openings that do not align with the openings in the first portion. The first and second molded units are joined along the first and second straight edges of the nailing portions, and spaced apart along the opposite edges, such that in an orientation to place over roof tiles and nail to the ridge beam, the first unit is above the second unit.
