Ventilated roof system with ridge vent

Abstract

A roofing system in a building structure having a ridge vent includes strips of composite material having a base material adapted to form a hermetic seal with the top surface of a roofing section and recesses in a top surface in which an air permeable material can be positioned. A strip is applied to roof sections adjacent to each side of a ridge vent so that a ridge cap can overlay the strips in spaced relation from the underlying roof sections and be sealingly secured to the roof sections. The strip material establishes a barrier between the ridge cap and the roof sections through which air can pass, but through which the passage of rain and insects is inhibited.

What is claimed is: 
     
         1 . A roof ventilation component comprising:
 an air permeable material having a generally rectangular shaped cross-section, wherein the roof ventilation component is configured to engage a roof surface and the roof surface is flat or includes ridges.   
     
     
         2 . The roof ventilation component of  claim 1 , further comprising a base material defining one or more recesses, wherein the air permeable material engages the base material at the one or more recesses. 
     
     
         3 . A method of installing a roof ventilation component, the method comprising:
 applying a roof ventilation component to a roof surface, the ventilation component comprising an air permeable material having a generally rectangular shaped cross-section, wherein the roof ventilation component is configured to engage the roof surface and the roof surface is flat or includes ridges; and   securing the ventilation component to the roof.   
     
     
         4 . The method of  claim 3 , wherein the roof ventilation component further comprises a base material defining one or more recesses, and wherein the air permeable material engages the base material at the one or more recesses.
