Abstract: A hip and ridge attachment device utilized in the roofing industry for the construction of roofs. Hip and ridge attachment devices are secured onto a rooftop once the installation of roofing felt is complete, but before the completion of roof tile installation. After the installation of the instant invention, tiles are secured thereon with an adhesive. The instant invention comprises sheet metal, formed into a V-form with walls extending a predetermined length from both sides of the V-form. Said walls are outwardly bent near their distal ends to lay flush against a roof surface. Optionally, embossings on the V-form increase the effective contact area for an adhesive when applied thereon. Additionally, said invention may have louvers for ventilation means.
