Laminated hip and ridge asphalt shingle

Abstract

Laminated hip and ridge asphalt shingle having a first, a second and a third layer laminated together by a lamination adhesive. The first layer is of two L-shaped configurations, each having a horizontal head portion and a vertical butt portion. The horizontal head portions are superimposed on each other, while the vertical butt portions are placed adjacent to each other and form a gap which allows bending of the first layer thereby preventing stress and breaking. The second layer overlaps the firs layer. The third layer only overlaps the head portion of the second layer. The top surface of the shingle is coated with mineral granules, while portions of the undersurface of the shingle are coated with a self-seal adhesive to secure the shingle to the hip or ridge of a roof. Disclosed also is a process for installing the hip and ridge shingle units which includes: bending a first unit along a central fold line, pressing and adhering it to both sides of the intersecting plane of a roof; nailing the unit to the roof deck on both sides of the hip or ridge; bending a second unit along a central fold line, pressing and adhering it to both sides of the intersecting plane and to the first unit so that the butt portion of the second unit overlaps the head portion of the first unit; nailing the second unit to the roof deck on both sides of the hip or ridge; and similarly securing the necessary additional units to the intersecting planes of the roof to complete the installation.
