A roof ridge vent having a ventilation component integrally secured to a
waterproof outer covering. During installation of the vent, both the
ventilation component and outer covering are simultaneously installed in
a single process step. The use and separate installation of cap shingles
or the like over a pre-installed vent is eliminated. The vent and
covering are provided in an elongate, continuous length in a spiral roll
and are installed as a single continuous length on a roof ridge overlying
an elongate open ventilation slot.
