Abstract

A roof vent is made from convoluted filaments. The roof vent includes a center section, a first end section, and a second end section, all made from convoluted filaments. The first and second end sections each include a top layer made from convoluted filaments and a bottom layer made from convoluted filaments. The thickness of the first end section may be substantially the same as a thickness of the center section. A filter may cover the top of the center section, the tops, ends, sides, and bottoms of the first and second end sections, and a portion of a bottom of the center section, leaving a middle portion of the bottom of the center section uncovered by the filter.
