ABSTRACT:
A roof ridge vent and installation includes a ventilation material having walls defining a plurality of separate open cellular cavities, such as a honeycomb material, that may or may not extend from the underside of a separate sheet material. Preferably, the walls of the ventilation material extend substantially vertically within the vent, and paths of ventilation, which extend from on open slot on the roof ridge to either longitudinally-extending side edge of the vent, extend transversely through the walls of the ventilation material. To this end, the walls are perforated or are made of an air permeable material, more preferably, a non-wicking hydrophobic material or a non-woven fabric having a multiplicity of closely spaced openings. Alternatively, paths of ventilation can be provided by channels formed between adjacent, spaced-apart sections of the ventilation material. Preferably, the vent is continuous and elongate and is stored and shipped in a spiral roll.
