  • Patent number: 6182400
    Abstract: An asphalt composition ridge cover and method of forming the same whereby a decorative appearance somewhat resembling that of a shake roof ridge cover is achieved. The ridge cover generally is a pair of flat, approximately rectangular pieces of asphalt composition roofing material, having a plurality of tabs at one end of each piece which are folded over one another thereby forming a region of increased thickness at that end. The two pieces are adhesively joined in a plurality of areas including an area disposed to both sides of the central fold that forms the ridge line of ridge cover when installed, thereby holding the ridge cover in a folded configuration. The adhesive joining in the vicinity of the central folding inhibits further bending along the central fold and thereby reduces cracking.
