Precipitation resistant ridge vent

DETAILED DESCRIPTION The present invention largely solves the above problems by providing a shingle over ridge vent that effectively excludes the entry of precipitation and foreign matter into the roof space.
The ridge vent is sturdy, easily manufactured and readily installed.
In addition, the filtering material that excludes precipitation is protected from factors that speed its deterioration.
The ridge vent is constructed of corrugated weather resistant material having a convoluted intermediate ply.
Airflow passages in the convoluted layer are linearly oriented generally perpendicular to the long axis of the ridge vent.
The material is cut and scored so that it may be folded to have a single top panel extending its entire length.
At either side of and below the top panel a plurality of folds create a plurality of stacked layers of the corrugated material with a plurality of airflow passages therethrough.
A routed groove may extend the length of the bottom side of the top panel of the ridge vent to facilitate bending the ridge vent to conform to different roof pitches and to provide an additional exit path for air flowing out of the ridge vent.
A sheet of air permeable, water resistant, woven or nonwoven fabric or other membrane is applied to the bottom side of the vent.
The filtering fabric is bonded to the corrugated material in the vicinity of the peak of the vent and on the bottom sides of the stacked, corrugated vent material.
When the ridge vent is applied to the roof ridge the filtering fabric forms a tent like structure such that any accumulated rainwater drains out through the bottommost layer of the stacked side vent portions of the ridge vent.
The enclosure of the filtering fabric inside the ridge vent protects the fabric from exposure to sunlight and other factors that encourage deterioration.
The ridge vent may be produced in lengthy continuous rolls or discrete sections for installation.
Discrete sections of ridge vent may be stacked flat or folded then stacked for shipping and handling
