ABSTRACT:
A top down trap lock shingle system that includes a plurality of identical shingles, each shingle having a bottom layer, an intermediate layer permanently attached to the bottom layer along the intermediate layer top edge forming a pocket between the bottom layer and the intermediate layer and a top layer permanently attached to said intermediate layer and permanently attached to said top edge of said bottom layer forming an extended tab along the top of the shingle that includes strips of adhesive and said bottom layer having an enlarged nailing or stapling zone that extends beyond the bottom edge of the intermediate layer, said attachment flange including a top adhesive layer and a bottom adhesive layer. The shingles are trapped and locked by inserting the top tab portion of the top area in a top down manner onto an above shingle row staggered to protect the seams and fastening the bottom edge of the shingle to the plywood roof thus trap locking each of the shingle rows in place. The laminated shingle system is especially durable and protectful against high winds preventing wind damage and water intrusion.
