a vent slot located through a roof structure along at least one of a roof ridge or hip ridge; a contoured roofing material having upwardly directed projections that forms a roof surface; at least one vent strip on the roof surface that extends on each side of the vent slot, the vent strip is comprised of synthetic fibers that are randomly aligned into an open web by an air flow and then joined by a phenolic or latex binder that is heat cured to form an air permeable mesh material having a generally uniform thickness, a density of about 0.08 to 0.1 grams per cubic centimeter (1.3 to 1.6 grams per cubic inch), and a crush recovery of at least 80%, the vent strip is resiliently compressible such that a space between the projections in the contoured roofing material is filled with the vent strip, and a portion of the strip is compressed into contact with and extends over the projections; and a cap overlying the slot and the vent strip. |
